DOAN, CRAIG H., and P. MICHAEL DAVIDSON. "Microbiology of Potatoes and Potato Products: A Review." Journal of Food Protection 63, no. 5 (May 1, 2000): 668–83. http://dx.doi.org/10.4315/0362-028x-63.5.668.
Abstract:
Many types of spoilage and pathogenic microorganisms exist on fresh, minimally processed, and fully processed potato products. Potatoes are processed into many products including frozen, dried, ready-to-eat, and minimally processed. The microbiological quality of finished potato products is influenced by the natural microflora, processing, handling, and human contact. The natural microflora of potatoes are influenced by soil and airborne inocula, agricultural practices, harvesting methods, and storage conditions. The microflora of processed products are influenced by all of the factors and conditions affecting the natural microflora as well as the processes applied to the product. Increased consumer demand for new and existing potato products highlights the importance of ensuring their microbiological safety. This review considers the sources of microorganisms, microflora, foodborne disease pathogens, and outbreaks associated with, and selected microbiological research involving, potatoes and potato products.

Abstract:
Minimally processed products are demanded by a growing market because consumers are looking for value-added products and ready to eat, but their marketing is limited by a short life and rapid deterioration of their components due to damage tissue processing operations, this affect the sensory quality of the final product mainly due to enzymatic, biochemical changes and microbial growth. Consequently, there is a need to find alternatives for the conservation of fresh-cut fruits and vegetables, alowing to reduce to a minimum the changes occurring in plant tissue. Among the alternatives that have been proposed, they are: The application of antimicrobial and antioxidants agents, calcium, edible coatings and packaging under modified atmospheres. Therefore, the aim of this review is to present an overview of available technologies with the potential to be used by the Colombian agricultural industry for the conservation of minimally processed fruits and vegetables, so that you will give added value to our products and access to new markets.

"The importance of agro-economic characteristics for minimal cassava processing: A review." Research, Society and Development 10, no. 7 (July 2, 2021): e57110716904. http://dx.doi.org/10.33448/rsd-v10i7.16904.
Abstract:
Cassava (Manihot esculenta Crantz) is a crop of extreme economic and agronomic value because it has several varieties, it is highly nutritious and extremely important in the food industry in the generation of products for human consumption. The objective of the present study was to characterize the culture of cassava by means of its peculiarities, potential of the product called minimally processed cassava, to describe the methods used in the generation of this product to understand the dynamics of consumption of this product. Because it is a relatively easy crop and has low nutritional requirements, cassava is grown in most of the national territory, with a growing increase in production every year. The products generated from cassava are appreciated and sold in the national and international territory, the minimally processed cassava is among the products generated by this culture, of great economic value and of great acceptance in the consumer market. The work was carried out by means of a bibliographic survey that address relevant issues about cassava and generated products, mainly minimally processed table cassava to provide an assembled and relevant knowledge to the scientific community in agri-food technologies.

Abstract:
In the United States, as much as 10% of the watermelon sold is as a minimally processed product. These products are prepared at the retail level as cubed flesh in plastic food containers or as halved slices wrapped in plastic film. The shelf life of these products at different temperatures is not known. In this study, `Allsweet' and `Jubilee' ripe watermelons were washed, wiped with a 5% bleach solution, and cut into transverse slices using surface-sterilized knives. Halves of these slices were sprayed with distilled water (pH 7.0) or with Natureseal plus 5% ascorbic acid (pH 4.5), wrapped with plastic film (0.05-mm thickness), and stored at 2 and 5 °C for 4 to 6 days. Weight loss of wrapped slices was 0.1 % at 2 and 5 °C after 4 days of storage and 0.5% of slices sprayed with Natureseal. Watermelon flesh became slimy after 3 and 5 days of storage at 5 and 2 °C, respectively, especially in slices treated with Natureseal. Fruit rinds developed brown stains and became very soft. In a separate study, watermelon slices (flesh and rind) placed in jars at 10 °C lost the characteristic watermelon odor after 2 days and a more pumpkin-like odor developed. Respiration after 1 day at 10 °C was 6 to 8 mL CO2/kg-h and increased after 5 days of storage to 13 and 25 mL CO2/kg-h for `Allsweet' and `Jubilee', respectively. Ethylene production was 0.04 to 0.06 μL/kg-h after 1 day of storage, increasing to 0.55 μL/kg-h after 5 days of storage. Results indicate that cut watermelon should be held at temperatures of 2 °C or less for no more than 3 days.

"Effect of Agronomic Practices on Yield and Quality of Borage at Harvest and During Storage as Minimally-Processed Produce." Agronomy 10, no. 2 (February 6, 2020): 242. http://dx.doi.org/10.3390/agronomy10020242.
Abstract:
Borage (Borago officinalis L.) is a hairy pubescent herb known throughout the world for its folk medicinal uses, as well as for many culinary uses. There is still little information on the cultivation needs of this species, especially for its use as vegetable crop and as fresh-cut produce. Hence, the aim of the research was to study the effects of agronomic practices on yield and quality of borage and on the storability as minimally-processed product. Two experiments were carried out in two consecutive years in order to evaluate the effect of plant density and plastic mulching on yield and quality of two borage accessions at harvest and during storage as minimally-processed produce for 14 days at 4 °C. The highest plant density (8 plants m2) determined the highest yield of plants and minimally-processed leaves with good quality retention during storage. Mulching had a positive effect on earliness, yield, and shelf life of minimally-processed leaves but also increased nitrate accumulation and reduced ascorbic acid content. Borage plants with lower spacing grown on mulched soil showed the best yield of plants and minimally-processed leaves irrespective of the borage accession tested. Borage plants can be used to produce minimally-processed entire leaves with good quality characteristics.

"Microbiological and Sensory Quality of Fresh Ready-to-Eat Artichoke Hearts Packaged under Modified Atmosphere." Journal of Food Protection 80, no. 5 (March 30, 2017): 740–49. http://dx.doi.org/10.4315/0362-028x.jfp-16-289.
Abstract:
ABSTRACT In recent years the sales of minimally processed vegetables have grown exponentially as a result of changes in consumer habits. The availability of artichoke buds as a ready-to-eat product would be, therefore, highly advantageous. However, minimally processed artichoke hearts are difficult to preserve because of their rapid browning and the proliferation of naturally occurring microorganisms. We developed artichoke hearts prepared as ready-to-eat products that maintain the characteristics of the fresh product. The microbiological stability, sensory qualities, and shelf life of the processed artichoke hearts were determined. During the shelf life, Salmonella, Listeria monocytogenes, and Escherichia coli counts were below the limits legally established by European regulations for minimally processed vegetables. The pH played an important role in microbial growth. Artichoke hearts had lower microbial counts in experiments conducted at pH 4.1 than in experiments conducted at pH 4.4, although the recommended threshold value for total plate count (7 log CFU/g) was not exceeded in either case. Sensory parameters were affected by the microorganisms, and artichoke products at lower pH had better sensory qualities. Vacuum impregnation techniques, modified atmosphere packaging, and low storage temperature were very effective for increasing the shelf life of minimally processed artichokes. The average shelf life was approximately 12 to 15 days.

Abstract:
In order to decrease microbial contamination, fresh-cut industry commonly uses sodium hypochlorite as a disinfection agent, however, the by-products such as trihalometanes and chloramines are potentially harmful for human health making necessary the search for alternative disinfectant agents. A comparative study on the effectiveness of different disinfection methods on the quality of minimally processed F. vesca strawberry is presented. The fruit was processed in a clean room through the following steps: reception, cutting, washing, draining, and packaging. The processed strawberries were packaged in thermally sealed polypropylene trays using passive modified atmosphere. During a storage period of 8 days at 4ºC, the quality parameters, sensory attributes, and microbial counts were determined. As conclusion, the use of lactic acid at a concentration of 2.5 g/l in the washing water was effective in reducing microbial counts, maintaining the sensory attributes and quality of the product during the storage. The present study demonstrates that the use of lactic acid in the washing water could be a good alternative of the use of sodium hypochlorite and suggests that strawberries could make an acceptable fresh-cut product.

Abstract:
AbstractObjectiveTo identify the use of ultra-processed foods – vectors of salt, sugar and fats – in the Norwegian diet through an assessment of food sales.DesignSales data from a representative sample of food retailers in Norway, collected in September 2005 (n150) and September 2013 (n170), were analysed. Data consisted of barcode scans of individual food item purchases, reporting type of food, price, geographical region and retail concept. Foods were categorized as minimally processed, culinary ingredients, processed products and ultra-processed. Indicators were share of purchases and share of expenditure on food categories.SettingSix geographical regions in Norway.SubjectsThe barcode data included 296 121 observations in 2005 and 501 938 observations in 2013.ResultsUltra-processed products represented 58·8 % of purchases and 48·8 % of expenditure in 2013. Minimally processed foods accounted for 17·2 % of purchases and 33·0 % of expenditure. Every third purchase was a sweet ultra-processed product. Food sales changed marginally in favour of minimally processed foods and in disfavour of processed products between 2005 and 2013 (χ2(3)=203 195,P<0·001, Cramer’sV=0·017,P<0·001).ConclusionsUltra-processed products accounted for the majority of food sales in Norway, indicating a high consumption of such products. This could be contributing to rising rates of overweight, obesity and non-communicable diseases in the country, as findings from other countries indicate. Policy measures should aim at decreasing consumption of ultra-processed products and facilitating access (including economic) to minimally processed foods.

Abstract:
Today’s society characterized by an increasing health consciousness and growing interest in the role of food for maintaining and improving human well-being and consumer health, in addition to their nutritional and sensory properties, foods are currently recognized as active and protective agents. Among the others, fresh-cut horticultural products stand out as convenient novel foods that fit the many feeds of a modern life style as they combine technical content with an innovative food concept. The international fresh-cut produce Association (IFPA) defines fresh-cut products as fruits or vegetables that have been trimmed and / or peeled and / or cut in to 100% usable product that is bagged or pre-packaged to offer consumers high nutrition, convenience, and flavour while still maintaining its freshness. In particular, fresh cut fruits attract consumers because they are fresh, nutritious, low priced, and ready-to-eat. As a consequence, a wide assortment of minimally processed fruits has been developed to meet consumers, needs for ‘quick” and convenient products, and to benefit from fruits healthy image. Present study was carried out to known the microbiological quality of minimally processed fruits and vegetable. Acidty, pH and moisture content was estimated under physico-chemical properties and TPC and Yeasts and mouls count was analysed for minimally processed cabbge and Pineapple available in Tirupathi Super markets.

Abstract:
Purpose – The purpose of this paper is to examine the usefulness of integrating measures of motivations in predicting purchase intentions of fresh cut products. In order to gain this purpose the authors developed a field study that involved about 425 consumers of fresh cut vegetables products. Design/methodology/approach – Questionnaire data were gathered in Italy on a Likert scale. Questions focussed on intentions to purchase fresh cut lamb’s lettuce from environmental sustainable farms, simulating a fresh cut product with an Eco-label. Data were analyzed using structural equation modeling (SEM). The SEM technique is used to develop propositions representing a theoretical approach in the context of the process for purchasing fresh cut products. With regard to distinguishing between the motives, the authors referred to the approach that sets out two different types of motive: health and green. Findings – The resulting managerial implications make it possible to assess how much the different types of motive influence the attitude and affect the choices and the behavior of the consumers. Originality/value – This implies important managerial implications for new marketing strategies for minimally processed food products, with the opportunity to take advantage of the potential adoption of an Eco-label.

Martins, Ramilo Nogueira, Ben-Hur Mattiuz, Leandra Oliveira Santos, Cristiane Maria Ascari Morgado, and Claudia Fabrino Machado Mattiuz. "Preservation of minimally processed 'aurora-1' peaches using additives." Revista Brasileira de Fruticultura 33, no. 4 (December 2011): 1229–39. http://dx.doi.org/10.1590/s0100-29452011000400023.
Abstract:
'Aurora-1' peaches establishes an interesting alternative as a minimally processed product, due to its characteristics like flavor, color, smell, and also because of its handling resistance. However, it has a short shelf life after a fresh-cut due to enzymatic browning and stone cavity collapse. The main purpose of this research was to test the additive with antioxidant effect to prevent browning in minimally processed 'Aurora-1' peaches. The minimal processing consists of washing, sanitizing, peelings and fruit stone extraction. After that, longitudinal cuts were made to obtain eight segments per fruit. The slices were immersed into the following treatment solutions: control (immersion in 2% ascorbic acid); 2% ascorbic acid + 2% calcium chloride; 1% sodium isoascorbate; 1% citric acid; 1% L-cysteine hydrochloride. The products were placed into rigid polystyrene trays branded MEIWA M-54, covered with 14 µm PVC film (OmnifilmTM) and kept in cold storage at 3ºC ± 2ºC and 65% RH for twelve days, and evaluated each three days. Appraised variables were appearance, soluble solids, titratable acidity, soluble carbohydrates and reducing sugars, total and soluble pectin, ascorbic acid, and peroxidase and polyphenol oxidase enzyme activity. L-cysteine gave to the minimally processed products a shelf life of twelve days, limmited by off-flavor. The treatment with ascorbic acid was efficient to maintainthe ascorbic acid content, with a shelf-life of nine days, limited by enzymatic browning.

Abstract:
The increasing demand of minimally processed fruits and vegetables signify a challenge to make them stable and safe to be consumed. The processing of this type of product may contribute higher risks of food borne illnesses. One of the foodborne pathogens in minimally processed fruits and vegetables is Listeria monocytogenes. The importance of understanding the characteristics of L. monocytogenes will help to determine how this microorganism occurs, grows, and survives in minimally processed fruits and vegetables. Proper and suitable methods to reduce L. monocytogenes so that it can not pose a significant risk to cause disease therefore are able to be determined according to the model of the growth and survival of L. monocytogenes in minimally processed fruits and vegetables.

Abstract:
A wide range of fresh conveniently packaged, minimally processed products are available on both local and global market in response to consumer demand for ready to eat food. Majority of these products are leafy vegetables, which are highly susceptible to quality changes during minimal processing operations (trimming, cutting, washing, drying, and packaging). Despite the available precautionary measures for maintaining quality attributes of raw and processed material, quality degradation due to minimally processing is unavoidable, also considering that a peeling, trimming and/or cutting operation is always present except than for baby leaves and small fruits. In addition, other operations as washing and drying are known to cause mechanical stresses and loss of sugars and nutrients. However, the extent to which quality is compromised depends on the produce and on the processing conditions, including equipment and their operational settings. This review aims to describe the main processing operations and equipment used, resuming the available information on their impact on final quality of fresh-cut products over storage, in order to identify areas for future research aiming to the enhancement of product quality

Abstract:
The objective of this work was to evaluate modified atmosphere effectiveness in minimally processed cauliflower aiming food safety maintenance for consumers, as conservation of product physical and chemical characteristics for better quality. Cauliflowers cv. Cindy were selected, washed, sanitized with sodium hypochlorite (200 mg L-1) and rinsed. After processing, they were immersed, one more time, in sodium hypochlorite solution (50 ppm) and dried by the air. Portions of 200 g were made and placed in different atmospheres: T1 = 0.05 % CO2 + 23 % O2; T2 = vacuum; T3 = tray of expanded polystyrene with polyvinyl chloride film (PVC) and T4 = 6 % CO2 + 4 % O2 + 90 % N2. The packages were stored in cold chamber at 5 ºC ± 1 and 85% ± 5 of relative humidity. Analysis were performed every two days and the evaluated traits were: loss of fresh mass, respiratory activity, soluble solids, titratable acidity, pH, reducing sugars, instrumental color, visual and microbiological analysis. The experimental design was completely randomized, in factorial design. Data were submitted to analysis of variance and means were compared using Tukey test at 5% of probability and regression analysis for storage period. Tray of expanded polystyrene with PVC delayed for two days product climacteric peak in relation to other modified atmosphere. Furthermore, it provided quality attributes maintenance. The best notes of visual appearance and the best intention of purchase were attributed to minimally processed cauliflower wrapped in modified atmosphere with 6% CO2. + 4% O2.

Abstract:
AbstractThe nutritional reformulation of processed food and beverage products has been promoted as an important means of addressing the nutritional imbalances in contemporary dietary patterns. The focus of most reformulation policies is the reduction in quantities of nutrients-to-limit – Na, free sugars, SFA,trans-fatty acids and total energy. The present commentary examines the limitations of what we refer to as ‘nutrients-to-limit reformulation’ policies and practices, particularly when applied to ultra-processed foods and drink products. Beyond these nutrients-to-limit, there are a range of other potentially harmful processed and industrially produced ingredients used in the production of ultra-processed products that are not usually removed during reformulation. The sources of nutrients-to-limit in these products may be replaced with other highly processed ingredients and additives, rather than with whole or minimally processed foods. Reformulation policies may also legitimise current levels of consumption of ultra-processed products in high-income countries and increased levels of consumption in emerging markets in the global South.

Abstract:
Minimally processed onion is a ready-to-use onion product offering the consumer a fully usable commodity, without much change to freshness of the produce. Effect of packaging and storage temperature on shelf-life in minimally processed onion was studied. Packaging and temperature play an important role in determining shelf-life in minimally processed onion. Onion pieces approx. 8-10mm thick were cut with a plain, sharp knife and subjected to dip-treatment with the firming agent, calcium lactate (2%), for 5 minutes. The samples were surface-dried and packaged in polypropylene bags of size 250 X 125mm, of variable thicknesses (25, 50 or 75μm) and stored at low temperatures and high RH:8±1°C and 83±2% RH; 10±1°C and 82±2% RH; and, 12±1°C and 80±2% RH. It was found that onion cv. Arka Sona sliced with a plain, sharp knife, pre-treated with 2% calcium lactate, surface-dried and packaged in polypropylene bags sized 250X125mm (50μm thick), and stored at 8+1°C and 83±2% RH retained freshness and nutritive value, were microbially safe and acceptable, with a shelf-life of 14 days at storage.

Abstract:
Food processing is used for transforming whole food ingredients into food commodities or edible products. The level of food processing occurs along a continuum from unprocessed to minimally processed, processed, and ultra-processed. Unprocessed foods use little to no processing and have zero additives. Minimally processed foods use finite processing techniques, including drying, freezing, etc., to make whole food ingredients more edible. Processed foods combine culinary ingredients with whole foods using processing and preservation techniques. Ultra-processed foods are manufactured using limited whole food ingredients and a large number of additives. Ultra-processed snack foods are increasing in food environments globally with detrimental implications for human health. This research characterizes the choices, consumption, and taste preferences of adolescents who were offered apple snack food items that varied along a processing level continuum (unprocessed, minimally processed, processed, and ultra-processed). A cross-sectional study was implemented in four elementary school classrooms utilizing a buffet of apple snack food items from the aforementioned four food processing categories. A survey was administered to measure students’ taste acceptance of the snacks. The study found that the students selected significantly (p < 0.0001) greater quantities of ultra-processed snack foods (M = 2.20 servings, SD = 1.23) compared to minimally processed (M = 0.56 servings, SD = 0.43) and unprocessed (M = 0.70 servings, SD = 0.37) snack foods. The students enjoyed the taste of ultra-processed snack foods (M = 2.72, SD = 0.66) significantly more (p < 0.0001) than minimally processed (M = 1.92, SD = 1.0) and unprocessed (M = 2.32, SD = 0.9) snack foods. A linear relationship was found between the selection and consumption quantities for each snack food item (R2 = 0.88). In conclusion, it was found that as processing levels increase in apple snack foods, they become more appealing and more heavily consumed by elementary school students. If applied broadly to snack foods, this conclusion presents one possible explanation regarding the high level of diet-related diseases and nutrient deficiencies across adolescents in America. Food and nutrition education, food product development, and marketing efforts are called upon to improve adolescent food choices and make less-processed snack food options more appealing and accessible to diverse consumers.

Abstract:
AbstractObjectiveTo examine the availability of packaged food products in New Zealand supermarkets by level of industrial processing, nutrient profiling score (NPSC), price (energy, unit and serving costs) and brand variety.DesignSecondary analysis of cross-sectional survey data on packaged supermarket food and non-alcoholic beverages. Products were classified according to level of industrial processing (minimally, culinary and ultra-processed) and their NPSC.SettingPackaged foods available in four major supermarkets in Auckland, New Zealand.SubjectsPackaged supermarket food products for the years 2011 and 2013.ResultsThe majority (84 % in 2011 and 83 % in 2013) of packaged foods were classified as ultra-processed. A significant positive association was found between the level of industrial processing and NPSC, i.e. ultra-processed foods had a worse nutrient profile (NPSC=11·63) than culinary processed foods (NPSC=7·95), which in turn had a worse nutrient profile than minimally processed foods (NPSC=3·27), P<0·001. No clear associations were observed between the three price measures and level of processing. The study observed many variations of virtually the same product. The ten largest food manufacturers produced 35 % of all packaged foods available.ConclusionsIn New Zealand supermarkets, ultra-processed foods comprise the largest proportion of packaged foods and are less healthy than less processed foods. The lack of significant price difference between ultra- and less processed foods suggests ultra-processed foods might provide time-poor consumers with more value for money. These findings highlight the need to improve the supermarket food supply by reducing numbers of ultra-processed foods and by reformulating products to improve their nutritional profile.

Minimally processed fruits offer a convenient and practical product to the consumer, with quality and freshness similar to the <em>in natura </em>product. The aim of this study was to apply coatings of croaker protein isolate (<em>Micropogonias furnieri</em>) with organoclay (montmorillonite) on minimally processed apples during 12 days of storage at 5 ± 1 °C. The apples were washed, peeled and cut into cubes. Coatings were then applied where T1 (control sample), T2 (croaker protein isolate coating) and T3 (croaker protein isolate coating and montmorillonite (MMT). The pieces were allowed to drain into sieves and these were stored in polyethylene terephthalete (PET) packaging for a period of 12 days at 5 ± 1 °C. Analyses of weight loss, firmness, color (Lightness (L*), Chroma a* and b*), pH, and microbiological analyses (psychrotrophic, yeasts and molds, <em>Salmonella</em> and <em>Escherichia coli</em>) were carried out. The analyses were carried out in triplicate and evaluated at the times of 1, 3, 5, 7, 9 and 12 days of storage. The use of croaker protein isolate coating and MMT proved promising in keeping weight loss, microbiological counts, enzymatic browning and firmness loss at minimum in minimally processed apples.

Abstract:
Minimal processing techniques should provide the market with fresh- like appearance. Fresh-cut vegetables are consumed widely and it is a healthy, nutritional and convenient option. The present study aimed to standardize and develop the minimally processed precut pseudostem. Two banana varieties were selected viz., ottuvazhai (syn Mupaddai) (V1), vayalvazhai (V2) for developing minimally processed product.To prevent browning, different pretreatments such as lemon juice, turmeric powder, curd, salt, water, citric acid, and vinegar were used at 1 to 5 % concentration. Two different packaging materials, viz., aluminum foil (P1) and low-density polypropylene (P2) were used.The chemical composition of banana pseudostem was analyzed. The moisture, browning index, color value and microbial study of the precut pseudostem were analyzed using standard procedures. The quality of minimally processed precut pseudostem was evaluated from the initial day to 9 days at ambient and refrigerated storage conditions. Among the pretreatments, citric acid pretreated precut pseudostem had an effective role against browning reaction.During storage conditions, a minimum changes were observed in Mupaddai variety (V1) precut pseudostem sample. At refrigerated condition, the minimally processed product (V1) from aluminum foil was good upto 9 days of storage condition.

Public Health Nutrition 22, no. 5 (February 12, 2019): 936–41. http://dx.doi.org/10.1017/s1368980018003762.
Abstract:
AbstractThe present commentary contains a clear and simple guide designed to identify ultra-processed foods. It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing. Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods. A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).

Abstract:
Sensory attributes like colour, flavour and texture are makers in the consumer's purchasing decision of minimally processed organic apples. Drying using low temperatures represent a simple and easy way for minimally processing of organic fruits, moreover this procedure is accepted in organic agriculture. The aim of this study is to establish the consumer acceptance of organic apples dried using two different temperatures and how they characterize the final product. In order to accomplish the proposed purpose, three organic apples cultivars ‘Rubinola’, ‘Topaz’ and ‘Gemini’ were sliced and dried in a professional dryer with air distribution, using temperatures like 35°C and 50°C. Consumer general impression regarding obtained dried organic apples was based on a questionnaire, which contain several questions about colour, flavour, texture and size, in two sessions organized during two different scientific events. Dried organic apples were tasted and evaluated by consumers of both genders with ages between 22 and 66 years old. The slice size of organic dried apples was preferred by over 50% of consumers for all apple varieties. Consumers preferred more the taste of ‘Gemini’ cv. apples dried at 50°C compared to those dried at 35°C. The consumer’s acceptance of minimally processed organic apples was oriented towards those dried at 50°C. Obtained results suggest that sensory attributes are very important in consumer acceptance of a minimally processed product by drying technology and more studies are required.

Abstract:
Fruits and vegetables (F&V) products are recommended for the daily diet due to their low caloric content, high amount of vitamins, minerals and fiber. Furthermore, these foods are a source of various phytochemical compounds, such as polyphenols, flavonoids and sterols, exerting antioxidant activity. Despite the benefits derived from eating raw F&V, the quality and safety of these products may represent a source of concern, since they can be quickly spoiled and have a very short shelf-life. Moreover, they may be a vehicle of pathogenic microorganisms. This study aims to evaluate the bacterial and fungal populations in F&V products (i.e., iceberg lettuces, arugula, spinaches, fennels, tomatoes and pears) by using culture-dependent microbiological analysis and high-throughput sequencing (HTS), in order to decipher the microbial populations that characterize minimally-processed F&V. Our results show that F&V harbor diverse and product-specific bacterial and fungal communities, with vegetables leaf morphology and type of edible fraction of fruits exerting the highest influence. In addition, we observed that several alterative (e.g., Pseudomonas and Aspergillus) and potentially pathogenic taxa (such as Staphylococcus and Cladosporium) are present, thus emphasizing the need for novel product-specific strategies to control the microbial composition of F&V and extend their shelf-life.

Abstract:
The effect of caseinate/chitosan blend on the shelf life of minimally processed apples was studied. In the first phase of the work, the effect of the biopolymer coating on the respiration rate of the minimally processed apples was studied as function of gas composition (5%, 10%, 21% of O2 with N2 as balance at 5 °C) and temperature (5 °C, 10 °C at 5% of O2 with N2 as balance). In the second phase, the shelf life of the packed product was studied during storage at 5 °C. The gas composition (O2%-CO2%) in the package headspace, relative humidity, pH, hardness, color and antioxidant capacity of the product were monitored after 0, 1, 4, 7, 11, and 14 days. The coating effectively reduced respiration rate of the product when oxygen was over 10%. In the presence of the coating, the reduction of oxygen did not affect the respiration rate. At 5% of O2, the respiration rate decreased by 50% by changing the temperature from 10 °C to 5 °C. Shelf life study showed that the chitosan—caseinate coating was able to preserve the mechanical properties and the antioxidant capacity of the product during storage by increasing the shelf life by 7 days to 11 days at 5 °C.

Abstract:
Abstract This research aims to develop a mathematical model for respiration rate and gasses exchange in modified atmosphere packaging (MAP), and examine the effect of packaging materials of MAP on quality of minimally processed papaya. Minimally processed papaya of IPB 9 Calina variety was stored at 5, 10, 15, 20, and 25 °C for respiration rate measurement. The MAP of the fruits were carried out using plastic films of polypropylene (PP), low-density polyethylene (LDPE) and polyethylene stretch-wrap (PE). The results showed that the respiration increased with increasing storage temperature. The relation between respiration and storage temperature was described using the Arrhenius equation with a coefficient of determination (R2) of 0.9189 for O2 consumption and 0.9881 for CO2 production. The packaging materials of LDPE and PE stretch-wrap provide a modified atmosphere effect in the package, while for polypropylene packaging did not reach steady conditions. The MAP using polyethylene stretch-wrap film was better in maintaining quality of the fruit. The MAP was designed with a product weight of 200 g, a packaging thickness of 20 μm and surface area of 0.0216 m2. The gas composition in the MAP was 7.2% O2 and 5.2% CO2 after 6 days of storage at 15 °C.

Abstract:
The development of food industry technologies and increasing the sustainability and effectiveness of processing comprise some of the relevant objectives of EU policy. Furthermore, advances in the development of innovative non-thermal technologies can meet consumers’ demand for high-quality, safe, nutritious, and minimally processed foods. Acoustic technology is characterized as environmentally friendly and is considered an alternative method due to its sustainability and economic efficiency. This technology provides advantages such as the intensification of processes, increasing the efficiency of processes and eliminating inefficient ones, improving product quality, maintaining the product’s texture, organoleptic properties, and nutritional value, and ensuring the microbiological safety of the product. This review summarizes some important applications of acoustic technology in food processing, from monitoring the safety of raw materials and products, intensifying bioprocesses, increasing the effectiveness of the extraction of valuable food components, modifying food polymers’ texture and technological properties, to developing biodegradable biopolymer-based composites and materials for food packaging, along with the advantages and challenges of this technology.

Abstract:
Food packaging systems are continually impacted by the growing demand for minimally processed foods, changing eating habits, and food safety risks. Minimally processed foods are prone to the growth of harmful microbes, compromising quality and safety. As a result, the need for improved food shelf life and protection against foodborne diseases alongside consumer preference for minimally processed foods with no or lesser synthetic additives foster the development of innovative technologies such as antimicrobial packaging. It is a form of active packaging that can release antimicrobial substances to suppress the activities of specific microorganisms, thereby improving food quality and safety during long-term storage. However, antimicrobial packaging continues to be a very challenging technology. This study highlights antimicrobial packaging concepts, providing different antimicrobial substances used in food packaging. We review various types of antimicrobial systems. Emphasis is given to the effectiveness of antimicrobial packaging in various food applications, including fresh and minimally processed fruit and vegetables and meat and dairy products. For the development of antimicrobial packaging, several approaches have been used, including the use of antimicrobial sachets inside packaging, packaging films, and coatings incorporating active antimicrobial agents. Due to their antimicrobial activity and capacity to extend food shelf life, regulate or inhibit the growth of microorganisms and ultimately reduce the potential risk of health hazards, natural antimicrobial agents are gaining significant importance and attention in developing antimicrobial packaging systems. Selecting the best antimicrobial packaging system for a particular product depends on its nature, desired shelf life, storage requirements, and legal considerations. The current review is expected to contribute to research on the potential of antimicrobial packaging to extend the shelf life of food and also serves as a good reference for food innovation information.

Abstract:
Several processes including controlled atmosphere, hypobaric storage and the application of protective films have been developed to extend shelf-life of fruits and vegetables. Recently, the application of edible coatings that can simulate controlled atmosphere storage to prolong product freshness is becoming a popular concept. The ability of these coatings to extend postharvest storage life depends on their differential permeability to CO2, O2 and water vapor.This talk will describe the developmental aspect and specific applications of edible coatings on various fresh and minimally processed fruits and vegetables.

Abstract:
Kale, a imortant crop for family farms, gains added value through minimal processing, enhancing freshness and convenience. UV-C irradiation emerges as a promising method for extending kale's shelf life without chemicals, although standardization is complex due to varying food resistances to light penetration.The study in question analyzed the effects of two different irradiation times on minimally processed cabbage, packaged in bowls and Styrofoam with plastic film, observing changes in physical-chemical and sensory parameters, such as loss of mass, color, pH, and visual and olfactory signs of deterioration. Six treatments were tested, varying the exposure time and the type of packaging, as well as a treatment with chlorinated sanitizer, using the Tukey test at 5% significance to determine the most effective in preserving the product. It was found that the packaging in the cumbuca resulted in less mass loss compared to the tray, and the lowest pH values were recorded in the treatment with UV-C light in the cumbuca, which may indicate that they are an option for reducing the stress of the product after processing. None of the color parameters a* and b* or the luminosity index differed from each other, so it is valid to say that the UV-C radiation and chlorine sanitization treatments applied in the experiment were able to preserve the color of the cabbage samples for a period of 8 days. Therefore, the application of UV-C light did not negatively affect the color, pH or loss of mass of the minimally processed cabbage and combined with the correct packaging can be an alternative to conventional sanitization, in addition to maintaining the original aroma of the product.

"Evaluation of Key Antimicrobial Properties of Moringa oleifera in Relation to Its Use as a Hand-Washing Product." Water 10, no. 9 (August 29, 2018): 1154. http://dx.doi.org/10.3390/w10091154.
Abstract:
Moringa oleifera (M. oleifera) is a fast-growing, drought-resistant plant found throughout tropical and subtropical regions. A previous study found dry M. oleifera leaf powder to be similarly efficacious to non-medicated soap when used as a hand-wash, even without the use of water. These characteristics suggest that M. oleifera could serve as a potential hand-washing product in water and resource-limited contexts, such as humanitarian and emergency settings. The purpose of this study was to assess the efficacy of minimally processed M. oleifera sourced locally in Ghana as a hand-washing and antimicrobial product by assessing whether: (1) different preparations of M. oleifera have antibacterial properties against potential diarrheal pathogens through set-up of die-off studies; (2) M. oleifera is an effective hand-washing product by conducting an in-vivo trial with healthy volunteers; and (3) M. oleifera has antimicrobial properties in potentially reusable aqueous solutions, such as rinse water used for hand-washing. M. oleifera was found to be significantly less effective than non-medicated soap when tested as a hand-washing product and promoted the growth of bacteria in aqueous solution. Moreover, the Moringa used in the study was found to be host to pathogenic bacteria, reinforcing the idea that it is unsuitable to use as a hand-washing product. Accordingly, in its minimally processed form, M. oleifera appears to be an ineffective antimicrobial agent and its use as a hand-washing product in water-scarce and resource-limited settings is not recommended.

Foods 10, no. 12 (November 25, 2021): 2919. http://dx.doi.org/10.3390/foods10122919.
Abstract:
Polyphenols are important bioactive compounds that are affected by processing. The consumer’s demand for minimally processed products contributes to the increase in non-thermal technologies such as high-pressure processing (HPP) in the food industry. This review is aimed at critically discussing the positive and negative effects of thermal treatment (TT) and HPP on the stability of different polyphenol families in agro-food products obtained from strawberry and apple, two of the most used fruits in food processing. Our findings show that the phenolic content was affected by processing, fruit type, polyphenol family, and storage conditions (time and temperature) of the final product. To increase shelf life, manufacturers aiming to preserve the natural content of polyphenols need to find the sweet spot between polyphenol stability and product shelf-life since the residual enzyme activity from HPP can affect polyphenols negatively.

Abstract:
ABSTRACT: In the present study, tannin extracts (rinsed or not) were compared to the use of sodium hypochlorite and tap water on fresh cut crisp leaf lettuce stored under modified atmosphere packaging. Effects of these sanitizers on total color difference and microbial levels of the product after sanitization and storage for 9 days at 3°C were evaluated. Performance of rinsed SM(r) tannin extract was comparable to the results of chlorine solution for all the analyzed parameters and; furthermore, that extract presented a high reduction in the initial bacterial count of minimally processed lettuce. However, storage of tannin extracts, did not impart better outcomes than the use of tap water. Therefore, the tannin extract storage SM(r) could be used in washing water to reduce the initial microbiological load, avoiding cross contamination in vegetables minimally processed.

Abstract:
Fruits that go through processes of sanitation, peeling, cutting and packaging, to be consumed soon afterwards, are called minimally processed fruits. Since fruit consumption is important in the human diet, consumers have looked for practicality in both preparation and consumption, a situation that includes minimally processed food. However, minimal processing can damage plant tissues, mainly by pulp browning and by accelerating changes in natural characteristics of the product. This study aimed at minimizing changes in minimally processed sliced peaches by immersing them in solutions which contained preservatives. The experiment was a completely randomized design in a 5x3 factorial scheme (5 anti-browning agents x 3 storage periods), with 4 trays per replicate and six slices of peaches in every replicate. Sliced fruits were treated with T1 = control (distilled water); T2 = ascorbic acid at 1% (m/v); T3 = sodium isoascorbate at 1% (m/v); T4 = ascorbic acid at 0.5% (m/v) + sodium isoascorbate at 0.5% (m/v); and T5 = citric acid at 0.5% (m/v) + sodium isoascorbate at 0.5% (m/v). Afterwards, they were placed on trays, covered with 9µ PVC film and stored at 4±1ºC for 0 (S1), 6 (S2) and 12 (S3) days. The following variables were evaluated: mass loss, pulp color, pulp firmness, soluble solids, titratable acidity, pH, rot spots, total phenols and antioxidant activity. The treatment that consisted of citric acid at 0.5% (m/v) + sodium isoascorbate at 0.5% (m/v) was the most efficient one to control oxidation; its values of browning indexes were the lowest ones, i. e., 15.62 (S1), 17.74 (S2) and 17.58 (S3). Besides, it kept the creamy-white color of the pulp throughout storage time.

Abstract:
Refrigerated fresh-cut fruit and vegetables are the most rapidly expanding area in produce sales. Shelf life for minimally processed produce depends on natural product senescence or spoilage organism decay. Shelf life limits, near-aseptic cutting facilities, refrigerated transportation, and refrigerated storage make it possible to ship precut cantaloupe coast to coast on a year-round basis. Thorough cantaloupe surface disinfection reduces potential spoilage organisms and harmful pathogens. We compared using vapor hydrogen peroxide and sulfur dioxide to the current practice of hypochlorite (HOCL) washing to reduce cantaloupe microbial load. After treatment, cantaloupe were stored in unsealed polyethylene bags at 2.2°C for 4 weeks. The HOCL treated fruit were scrubbed and soaked for 5 minutes in a commercial HOCL solution. After 4 weeks, the HOCL washed fruit had reduced visible molds compared to controls. Cantaloupes fumigated for 60 minutes with 5000 or 10,000 ppm sulfur dioxide developed sunken lesions but no significant decay after 4 weeks storage. Cantaloupes, treated 60 minutes with 3 mg·L–1 volume vapor hydrogen peroxide, did not show injury or significant decay after 4 weeks storage. Sulfur dioxide and vapor hydrogen peroxide show promise as alternatives to HOCL.

Abstract:
The principles of application of a Shelf Life Decision System (SLDS) for the optimization of the distribution of chilled fresh and minimally processed food products are developed. The SLDS integrates predictive kinetic models of food spoilage, data on initial quality from rapid techniques, and the capacity to continuously monitor temperature history of the food product with Time Temperature Integrators (TTIs) into an effective chill chain management tool that leads to an improved narrow distribution of quality at consumption time, effectively reducing the probability of products consumed past shelf life end. The applicability and effectiveness of the SLDS is demonstrated and evaluated based on actual food spoilage and TTI kinetics and chill chain data employing the Monte Carlo simulation method.

Abstract:
Recently, consumers’ demand for fresh, nutritious, and convenient food has shown a significant rise. This trend has forced increased sales of minimally processed and/or pre-packed fruit- and vegetable-based products. New product development and the diversification of plant-based foods have supported this growth. The food production sector should balance this requirement with the necessity to provide safe food with extended shelf life while meeting consumer demands for novel, nutritious, and affordable food products. The use of alternative “soft hurdles” may result in a decrease in the rate of food deterioration and spoilage attributed to microbial activity or other physiological/chemical degradation reactions. The objective of the article is to provide a systematic review of the preservative effect of the available hurdles implemented during processing and packaging of fresh-cut fruits and vegetables, focusing on recent applications aiming at improving product quality and prolonging their limited shelf life.

Abstract:
ABSTRACT Biodegradable packaging may replace non-biodegradable materials when the shelf life of the packaged product is relatively short, as in minimally processed foods. The objective of this work was to evaluate the efficiency of biodegradable films comprising starch/polyvinyl alcohol (PVOH)/alginate with the addition of 0 or 0.5% of essential oil of copaiba (EOCP) or lemongrass (EOLM) compared to poly-vinyl chloride (PVC) films in the storage of minimally processed lettuce. Lettuce samples cut into 1-cm strips were placed in polypropylene trays wrapped with biodegradable films and stored at 6 ± 2 °C for 8 days. PVC films were used as controls. The biofilms presented 11.43-8.11 MPa resistance and 11.3-13.22% elongation, with water vapor permeability (WVP) of 0.5-4.04 x 10-12 g. s-1.Pa-1.m-1; thus, the films' properties were considered suitable for the application. The lettuce stored in PVC presented minor total soluble solids (TSS), less luminosity (L), higher intensity of yellow color (b), and eight times less mass loss than that stored in biodegradable films. Multivariate analysis showed that the lettuce lost quality after 2 days of storage in PVC films, representing a different result from the other treatments. Lettuce stored in biodegradable films for 2 and 4 days showed a greater similarity with newly harvested lettuce (time zero). The films with or without the addition of essential oil showed similar characteristics. Biodegradable films were considered viable for the storage of minimally processed lettuce.

Abstract:
Multistate outbreaks of Escherichia coli O157:H7 infection in 2005 and 2006 associated with fresh and especially minimally processed produce greatly escalated the application of rapid pathogen detection systems to safety management in this food category. Pathogen testing was rapidly integrated into preharvest qualification for field lots, incoming raw produce, or final product. The raw produce and final product were incorporated into test-and-hold programs, typically within a 10-h time frame. To enhance consumer safety and provide guidance for the industry, an assessment of selected kits in comparison to a culture-based method was undertaken. Four primary kits were compared: the Neogen Reveal, SDI RapidChek, BioControl GDS O157, and Qualicon BAX O157 MP. Nine different leafy greens were freshly harvested and inoculated with a five-isolate mixture of E. coli O157:H7 at 10 CFU/25 g of sample, and cultures were enriched following the specified protocol. The PCR method was most consistent for identifying the presence of the inoculated pathogen in the shortest period of time. For the red-pigmented leafy vegetables red butter lettuce, curly endive, red lettuce, and lollo rosa, 13, 38, 88, and 100% false-negative results, respectively, were obtained with the immunoassays, but PCR detection was minimally affected. Immunoassays were negatively affected by delays in achieving critical threshold populations during the allowed enrichment period. Leafy green type, temperature abuse, and preharvest environment were unlikely to affect the results of PCR-based kits. Findings strongly suggest that product testing systems using 8-h detection cutoffs may give false-negative results. These issues become very important in high-throughput testing and retest protocols for presumptive pathogen-positive lots of produce.

Abstract:
ABSTRACTThe poultry industry is faced with compounding pressures of maintaining product safety and wholesomeness while keeping up with consumer trends of all-natural foods and label accuracy. Consumers are increasingly demanding that their foods be minimally processed and contain compounds that are easily read and recognized, i.e., products must be clean labeled. The purpose of this review is to briefly describe several natural antimicrobial agents that can be incorporated into poultry processing. These compounds and their essential oils were included in this mini-review because they are generally recognized as safe by the U.S. Food and Drug Administration and are considered clean label: thyme extract, rosemary extract, garlic, and oregano. This list of natural antimicrobial agents by no means includes all of the options available to poultry processors. Rather, this review provides a brief glance at the potential these natural antimicrobial agents have in terms of reduced pathogenicity, increased shelf stability, and sensory acceptability through direct product application or as part of the product packaging.

STORED AT TWO DIFFERENT TEMPERATURES." Revista Caatinga 29, no. 1 (March 2016): 25–36. http://dx.doi.org/10.1590/1983-21252016v29n104rc.
Abstract:
ABSTRACT: This work studied the physical, chemical and biochemical alterations in minimally processed yam stored at two different temperatures, as well as the incidence of bacteria of the genus Pseudomonas. The experimental design was completely randomised in a 2x8 factorial design, with two storage temperatures (5 and 10°C) and eight storage times (0, 2, 4, 6, 8, 10, 12 and 14 days). Experiments were in triplicate. Yam was selected, peeled and cut into slices of approximately 3 cm thickness. The slices were rinsed with water, sanitised and then drained in kitchen strainers. Approximately 300 g of the processed product were packed in nylon multilayers 15 µm thick, 15 cm wide and 20 cm long. The packs were sealed, weighed and kept at 5 and 10 ± 2°C for 14 days. Fresh weight loss, baking time, enzymatic activity of polyphenol oxidases, peroxidases and catalases, total soluble phenol content, and antioxidant capacity were evaluated, as well as visual analysis and incidence of Pseudomonas sp. Means of temperatures were compared by Tukey´s test at 5% significance. Yam storage at 5°C reduced weight loss and kept visual quality for longer; it also reduced cooking time and the activity of the enzymes polyphenol oxidase and peroxidase. In contrast, it promoted higher content of total soluble phenols, as well as a higher catalase activity and antioxidant capacity. During the storage time, there was no incidence of Pseudomonas sp. Minimally processed yam stored at 10°C may be sold for up to six days, and yam stored at 5ºC for up to 14 days.

Abstract:
Ultra-processed, pre-packaged foods are becoming a growing part of our diet, while displacing whole and minimally processed foods. This results in an increased intake of free sugar, salt, and saturated fats, that have a profoundly negative effect on health. We aimed to assess the trend in free sugar content in pre-packaged foods in Slovenia and evaluate the efficacy of industry self-regulations designed to combat the excess consumption of free sugar. A nation-wide data collection of the Slovenian food supply was performed in 2015 and repeated in 2017. In 2017, 54.5% of all products (n = 21,115) contained free sugars (median: 0.26 g free sugar/100 g). Soft drinks became the main free sugar source among pre-packaged goods (28% of all free sugar sold on the market) in place of chocolates and sweets, of which relative share decreased by 4.4%. In the categories with the highest free sugar share, market-leading brands were often sweeter than the average free sugar value of the category. This indicates that changes in on-shelf availability towards a greater number of healthier, less sweet products are not necessarily reflected in healthier consumers’ choices. Relying solely on voluntary industrial commitments to reduce free sugar consumption will likely not be sufficient to considerably improve public health. While some further improvements might be expected over the longer term, voluntarily commitments are more successful in increasing the availability of healthier alternatives, rather than improving the nutritional composition of the market-leading products. Additional activities are, therefore, needed to stimulate reformulation of the existing market-leading foods and drinks, and to stimulate the consumption of healthier alternatives.

Abstract:
Edible coatings have several advantages in preserving foods, such as avoiding water loss, controlling microbial growth, and reducing the need for preservatives added directly to the product. Antimicrobial action can be obtained by adding antimicrobial substances including phenolic compounds commonly found in plant extracts. This study evaluated the phenolic compounds content, antioxidant and antimicrobial activity of pulp, and seed extracts of Mimusopsis comersonii (popularly known in Brazil as abrico), besides the phenolic compounds were identified and quantified in the pulp extract. Edible coatings were incorporated with pulp extract in order to evaluate the preservation of minimally processed apples and baroa potatoes against foodborne bacteria, and enzymatic browning was also determined. Myricetin-3-glucoside, quercetin-3-glucoside, and kaempferol-3-glucoside were identified as major flavonoids in the apricot pulp extract. The seed and pulp extracts inhibited all tested microorganisms, especially Staphylococcus aureus and Salmonella Typhimurium. Edible coatings added with 9% of phenolic extract showed in vitro antimicrobial activity, in addition to being effective in preventing enzymatic browning in minimally processed apples and baroa potatoes for up to 15 days of storage. They were also effective in reducing up to 2 log CFU/g of aerobic mesophiles after 15 days of storage for apples, even though no microbial inhibition in baroa potatoes was observed under the same conditions. The addition of pulp phenolic extract in edible coatings proved to be an alternative in the preservation of apples and in the antibrowning activity of minimally processed baroa potatoes.

"Effect Of Light Environment On Harvest Quality And Postharvest Behavior Of Minimally Processed Sweet Pepper." European Scientific Journal, ESJ 12, no. 15 (May 30, 2016): 406. http://dx.doi.org/10.19044/esj.2016.v12n15p406.
Abstract:
The aim of this study was to evaluate the effect of two light environments on two maturity stages of sweet pepper and the postharvest behavior of minimally processed product using passive modified atmosphere. The size and fruit morphology were measured at harvest. Overall visual quality, gas concentration inside the bags, weight loss, soluble solids, firmness, electrolyte leakage, carotenoids and ascorbic acid were determined during the storage period. Results showed that quality parameters were affected by radiation and processing. Shaded pepper fruits showed higher water content and lower size compared to fruits exposed to full radiation. Fruit nutritional value was maintained, but after six days was not marketable. Visual quality of intact fruit was not affected without differences between treatments. Shelf life processed red fruits as julienne was reduced, being the worst performing during storage. Post-harvest visual quality was in relation to gases composition (O2 and CO2) inside the trays.

Abstract:
The first goal of this study was to determine the packaging film O2 permeability required to maintain a steady-state O2 concentration of 3% in modified-atmosphere packaging (MAP) of minimally processed romaine lettuce (Lactuca sativa L.). The second goal of the study was to determine the extent to which MAP could preserve lettuce quality and consequently extend product shelf life. Oxygen consumption rates of commercially prepared lettuce samples were determined in a closed system for each of three atmospheres (3% O2 combined with either 6%, 10%, or 14% CO2). Enzymatic, quadratic, and linear mathematical models were compared to determine which best described the respiratory data. The linear model was the most suitable and was used to predict the O2 consumption rate of the minimally processed romaine lettuce under the desired package headspace gas concentrations. The predicted O2 consumption rate was used to calculate the necessary O2 permeability for the packaging film. Packages (21.6 × 25.4 cm) were constructed from a polypropylene-polyethylene-laminate film with the appropriate O2 permeability. Packaged samples were stored under three modified atmospheres (MAs) (3% O2 combined with either 6%, 10%, or 14% CO2) for 20 days, and headspace gas concentrations, lettuce appearance, and color were evaluated every other day. Growth of pectinolytic and lactic acid bacteria was also studied. The O2 consumption rate of the lettuce decreased with increasing CO2 levels. The O2 levels in the MA packages equilibrated at 7% to 11%. Compared to a control atmosphere of air, MAP delayed the development of tissue discoloration. Preliminary results indicated no effect of MAP on microbial growth. Of the three CO2 levels, 10% was slightly more effective than 6% and 14%. Critical choice of packaging permeabilities combined with MAP maintained the quality of minimally processed romaine lettuce and thereby increased shelf life by about 50%.

Abstract:
Minimal processing of eggplant (Solanum melongena L.) generates loss of firmness and polyphenol oxidase catalyzes the oxidation of phenolic compounds producing enzymatic browning. The aim of this study was to evaluate the effect of 1% ascorbic acid and 2% calcium ascorbate in aqueous solution at natural pH of the antioxidant (pH 2.6 and 7.8, respectively), or adjusted to pH 5 with generally recognized as safe substances, mantaining the quality of minimally processed eggplant stored at 5 °C for 6 d. Water was used as a control. The color, firmness, polyphenol oxidase activity, and visual quality was evaluated in the freshly cut fruit at 3 and 6 d of storage. No effect of the treatments on firmness or polyphenol oxidase activity was observed. At 3 d of storage, a correlation was observed between polyphenol oxidase activity and the visual evaluation of the cut product. Samples treated with 2% calcium ascorbate and the rest of the treatments at pH 5 had a lower browning index than those treated with 1% ascorbic acid and the control. At the end of the storage period, the visual quality of the eggplant samples treated with 1% ascorbic acid at pH 5 was evaluated above the marketing limit, whereas those treated with 1% ascorbic acid at pH 2.6 had the lowest quality indicators. An adjustment to pH 5 helps to preserve the luminosity and visual quality of the eggplant, however firmness was not affected by calcium ascorbate or the pH of the medium.

"High-Pressure Processing Effects on Microbiological Stability, Physicochemical Properties, and Volatile Profile of a Fruit Salad." Foods 13, no. 9 (April 24, 2024): 1304. http://dx.doi.org/10.3390/foods13091304.
Abstract:
Nowadays, consumers are more aware of the effects of their diet on their health, and thus demand natural or minimally processed food products. Therefore, research has focused on processes that assure safe products without jeopardizing their nutritional properties. In this context, this work aimed to evaluate the effects of high-pressure processing (550 MPa/3 min/15 °C, HPP) on a fruit salad (composed of melon juice and pieces of Golden apple and Rocha pear) throughout 35 days of storage at 4 °C. For the physicochemical properties analysed (browning degree, polyphenol oxidase activity, antioxidant activity (ABTS assay), and volatile profile), a freshly made fruit salad was used, while for the microbiological tests (total aerobic mesophiles, and yeast and moulds) spoiled melon juice was added to the fruit salad to increase the microbial load and mimic a challenge test with a high initial microbial load. It was determined that processed samples were more microbiologically stable than raw samples, as HPP enabled a reduction of almost 4-log units of both total aerobic mesophiles and yeasts and moulds, as well as an almost 1.5-fold increase in titratable acidity of the unprocessed samples compared to HPP samples. Regarding browning degree, a significant increase (p < 0.05) was observed in processed versus unprocessed samples (roughly/maximum 68%), while the addition of ascorbic acid decreased the browning of the samples by 29%. For antioxidant activity, there were no significant differences between raw and processed samples during the 35 days of storage. An increase in the activity of polyphenol oxidase immediately after processing (about 150%) was confirmed, which was generally similar or higher during storage compared with the raw samples. Regarding the volatile profile of the product, it was seen that the compounds associated with melon represented the biggest relative percentage and processed samples revealed a decrease in the relative quantity of these compounds compared to unprocessed. Broadly speaking, HPP was shown to be efficient in maintaining the stability and overall quality of the product while assuring microbial safety (by inactivating purposely inoculated microorganisms), which allows for longer shelf life (7 versus 28 days for unprocessed and processed fruit salad, respectively).
