Full textAbstract:
Fruit wine is an important part of our diet that contains essential part of vitamin and minerals that contribute to overall strength for our health. Like other beverages fruit wines are undistilled alcoholic beverages usually made from grapes or other fruits such as peaches, plums or apricots, banana, elderberry, or black berry which are nutritive, more tasty, and mild stimulants. These fruits undergo a period of fermentation and aging. They usually have an alcohol content ranging between 5 and 13%. Wines made from fruits are often named after the fruits. No other drinks, except water and milk, have earned such universal acceptance and esteem throughout the ages as has wine. Wine is a food with a flavor like fresh fruit which could be stored and transported under the existing conditions. Being fruit-based fermented and undistilled product, wine contains most of the nutrients present in the original fruit juice. The nutritive value of wine is increased due to the release of amino acids and other nutrients from yeast during fermentation. The quality of fruit wine is easily affected during fermentation due to inappropriate selection of strain for fermentation and poor management of others fermentation conditions. In this present review, I discussed, history of fermentation, initial quality of grape fruit and wine quality, fermentation stage of wine, factors influencing fermentation and wine quality

Full textAbstract:
‘Aliza’ is a new pomelo × mandarin hybrid (Citrus maxima, cv. Red Chandler × Citrus reticulata, cv. Ora) developed by the Israeli citrus breeding program at the Volcani Institute. Here, we aimed to characterize the quality and flavor of ‘Aliza’ fruit as compared to other commercial citrus fruit, specifically pomelo (C. maxima), grapefruit (Citrus paradisi), orange (Citrus sinensis) and mandarin (C. reticulata). ‘Aliza’ fruits have a similar size as grapefruits, but have a thinner peel and a unique yellowish/golden color. ‘Aliza’ fruits are completely seedless and have especially high juice contents. They also have a unique, highly preferred flavor, characterized by high sweetness and moderate bitterness and acidity, with strong citrusy and tropical fruity aromas. Sensory analyses conducted with the aid of a trained panel and an electronic tongue revealed that the flavor of ‘Aliza’ fruits is different from the flavors of other citrus species. Consumer acceptance and preference tests revealed that ‘Aliza’ fruit are highly appreciated and favored. The aroma volatile profile of ‘Aliza’ fruit was somewhat similar to those of pomelo and grapefruit, but very different from those of orange and mandarin. Overall, ‘Aliza’ fruits can be distinguished from other citrus fruits by their unique color, high juice content and exceptional, unique flavor.

Full textAbstract:
In 2001 and 2002, we imposed a wide range of croploads (0-15 fruits/cm2 of TCA) on 4- and 5-year-old Honeycrisp/M.9 trees by manual hand thinning soon after bloom to define appropriate croploads that give adequate repeat bloom and also the best fruit quality. At harvest each year we evaluated fruit ripening and quality. Samples were stored for 5 months in air at 38 °F and 33 °F and evaluated for fruit firmness and storage disorders. Cropload was negatively correlated with tree growth, return bloom, fruit size, fruit red color, fruit sugar content, fruit starch content, fruit firmness, fruit acidity, fruit bitter pit, fruit senescent breakdown, fruit rot and fruit superficial scald, but was positively correlated with leaf blotch symptoms, fruit internal ethylene concentration at harvest, and fruit soggy breakdown. There was a strong effect of cropload on fruit size up to a cropload 7, beyond which there was only a small additional effect. Although there was considerable variation in return bloom, a relatively low cropload was required to obtain adequate return bloom. Fruit red color was reduced only slightly up to a cropload of 8 beyond which it was reduced dramatically. The reduced fruit color and sugar content at high croploads could indicate a delay in maturity of but, fruits from high croploads were also softer, had less starch and greater internal ethylene. It that excessive croploads advance maturity. Overall, croploads greater than 10 resulted in no bloom the next year, and poor fruit size, color and flavor, but these fruits tended to have the least storage disorders. Moderate croploads (7-8) resulted in disappointing return bloom and mediocre fruit quality. For optimum quality and annual cropping, relatively low croploads of 4-5 were necessary.

Full textAbstract:
Smart packaging of fresh produce is an emerging technology toward reduction of waste and preservation of consumer health and safety. Smart packaging systems also help to prolong the shelf life of perishable foods during transport and mass storage, which are difficult to regulate otherwise. The use of these ever-progressing technologies in the packaging of fruits has the potential to result in many positive consequences, including improved fruit quality, reduced waste, and associated improved public health. In this review, we examine the role of smart packaging in fruit packaging, current-state-of-the-art, challenges, and prospects. First, we discuss the motivation behind fruit quality monitoring and maintenance, followed by the background on the development process of fruits, factors used in determining fruit quality, and the classification of smart packaging technologies. Then, we discuss conventional freshness sensors for packaged fruits including direct and indirect freshness indicators. After that, we provide examples of possible smart packaging systems and sensors that can be used in monitoring fruits quality, followed by several strategies to mitigate premature fruit decay, and active packaging technologies. Finally, we discuss the prospects of smart packaging application for fruit quality monitoring along with the associated challenges and prospects.

The aim of the study was to find effects of tomato grafting on another cultivar. The tomato cultivars used as scions were Yeni Talya, Swanson and Beril. Cultivars used as rootstocks were Beaufort and Arnold. Cleft grafting methods were applied. The following characteristics of grafted and nongrafted plants were recorded: fruit index, number of fruits/truss, fruit weight, fruit yield, dry matter, pH, concentration of soluble solids, titratable acidity, total sugar and lycopene and vitamin C. The results showed that fruit yield and fruit index, number of fruits/truss and fruit weights were improved by grafting. Fruit quality, measured in terms of dry matter, concentration of soluble solids, total sugar, and vitamin C content, was lower in the fruits of grafted plants than in nongrafted ones. No significant difference in lycopene and pH content was found. Titratable acid content was improved by grafting. A positive effect of grafting was recorded when Beaufort was used as rootstock. These results showed that grafting could be an advantageous alternative in tomato production.

Abstract: Digital images and computer sciences have become two powerful tools in several areas, such as astronomy, medicine, forensics, etc. In the last few years, computer sciences are getting involved in agricultural and food science to decide based on estimated or actual parameters named features. Rottenness is the state of decomposing or decaying the quality of the fruit, which not only affects the taste and appearance but also modifies its nutritional composition, causing the presence of mycotoxins dangerous for humans. Detecting rotten fruits has become significant in the agricultural industry. Usually, the classification of fresh and rotten fruits carried by humans is not effective for the fruit farmers. Human beings will become tired after doing the same task multiple times, but machines do not. Thus, the project proposes an approach to reduce human efforts, reduce the cost and time for production by identifying the defects in the fruits in the agricultural industry. If we do not detect those defects, those defected fruits may contaminate good fruits. Hence, we proposed a model to avoid the spread of rottenness. The proposed model classifies the fresh fruits and rotten fruits from the input fruit images. Here, we use a trained deep learning model i,e sequential model to detect whether a fruit is fresh or rotten. In this work, three types of fruits, such as apple, banana, and oranges are used as a dataset. The experiments were done using a dataset composed of around 12000 images divided by 6 classes, 3 fresh fruits, and 3 rotten fruits

Full textAbstract:
Commercial fruit baby food is a preserved fruit product usually made with fruit purees, sugar, water and variable additives (thickening agents, antioxidants, etc.). As the foodstuffs intended for particular nutritional uses, baby foods for infants and young children conforms to a set of strict guidelines e.g. maximum levels for pesticide residues, microbiological contamination, addition of additives, labelling, etc. However, being an important supplement to children diet and/or for their progressive adaptation to ordinary food, the nutritional quality of commercial fruit baby food in very important. Ten samples of commercial fruit baby food from the market were analysed for the fruit content, ascorbic acid and total polyphenols content and total antioxidant capacity determined by DPPH method. Hydroxymethylfurfural (HMF) and furfural content were followed as the time-temperature effort indicators. The method for the estimation of fruit content in products was based on the concentration of glucose, fructose, sorbitol, potassium, formol number, malic and citric acid, phosphorus, ash and refractive index and the results were compared with the Code of practice of AIJN and literature sources. The study indicates that there are big differences in composition and quality of commercial fruit baby food, whereas some samples contain fruits only, another products are diluted with significant amount of sugar, water and starchy fillers.

Full textAbstract:
Southern assortment of cherries does not quite meet the modern requirements of production. Many varieties are low-productive, not resistant to cherry leaf spot ( Coccomyces hiemalis ) and moniliosis ( Monilia cinerea ), small-fruited, with low taste qualities. However, new varieties have been created that have not been studied by the complex of consumer and commodity qualities of fruits. Thus, evaluation of new varieties for these traits is relevant. The aim of the research was to evaluate cherry varieties of different origin for commodity, biochemical, and consumer qualities of fruits. The research was carried out in the Kuban horticultural zone of the Krasnodar territory. Objects of the research were 9 varieties of sour cherry trees. Field and laboratory studies were conducted according to Program and methodology of varietal study of fruit, berry and nut crops (1999), Methodological instructions on chemical and technological variety testing of vegetable, fruit and berry crops for canning industry (1993). Statistical analysis was carried out according to B.A. Dospekhov (2014) and G.F. Lakin (1990). It was found that the average fruit weight of cherry varieties varied not significantly - from 2.72 to 6.45 g, which was confirmed by the coefficient of variation (23.3 %). Indicators of maximum and minimum fruit weight varied significantly in varieties, coefficients of variation were 27.2 and 29.7 %, respectively. The following cherry varieties with large fruits were identified: Timati, Igrushka, Duk Ivanovna, Duk Khodosa, Prizvaniya and Svetlaya. were distinguished. Cherry varieties with high sugar content in fruits were as follows: Feyа, Dzhusi Frut and Igrushka. Feyа, Duk Khodosa, Prizvanie, Svetlaya and Dzhusi Frut had fruits with low acidity; Feyа, Dzhusi Frut and Igrushka fruits were characterized by high content of soluble solids in fruits. Feyа, Igrushka and Duk Khodosa fruits had the highest content of vitamin C; Igrushka, Duk Khodosa, Prizvanie, Svetlaya and Dzhusi Frut were rich in Vitamin P; Duk Khodosa, Prizvanie, Dzhusi Frut and Duk Ivanovna had the largest anthocyanin content. Therefore, Igrushka and Duk Khodosa cherry varieties are recommended for growing in the southern Russia and breeding for improvement of fruit quality.

Abstract: In agricultural and horticulture. Image processing is one of the widely used application. in this paper automated quality identification using some image processing techniques is there that can be done using some image features which help in quality detection of vegetables like shape, color and size. tomatoes are in high demand because the world population consumes them daily. This research is to improve tomato production and fruit quality through fruit measurement methods, which have a low impact factor on fruit and plant during measurements. As there is high demand for quality fruits in the market fruit grading process is considered as very important. Fruit grading by a human may cause inefficient and it may also leads to some error. Researchers have developed numerous algorithms for quality grading and sorting of fruits. color is most important features for indentifying disease and maturity of the fruit. Here a sorting process is introduced where the image of the fruit is captured and analyzed using image processing techniques and the defected fruit is discarding by this process. the main aim of this paper is to do the quality check of the fruits within a short span of time.

Apparently, there are no custard apple cultivars defined for the northeastern region of Brazil. The establishment of breeding programs aimed at the selection of types from productive locations for later cloning is desirable. This work's objective was to evaluate the yield (during the first three crops) and quality (first crop) of fruits from 20 half-sibling custard apple tree progenies, selected from home orchards. An additional objective was to estimate genetic parameters for the traits evaluated. A micro sprinkling-irrigated experiment was conducted in Mossoró-RN, Brazil, as random blocks with five replications. In characteristics evaluated for periods longer than a year (diameter, height and mean weight of fruits, number of fruits ha-1 and fruit yield (kg ha-1), and a split-plot design was adopted, with progenies considered as plots and annual cropping seasons as subplots. The best progenies in terms of fruit yield (A3 and A4) are not necessarily the best for fruit dimensions and fruit mean weight (A2, FE4, JG1, JG2, SM1, SM7, and SM8). These progenies show great potential to be used in future studies on crosses or on vegetative propagation. In this regard, progeny JG2 should be highlighted as promising in terms of yield and fruit size. The progenies are not different with regard to percentages (in relation to mean fruit mass) of pericarp, endocarp, seeds, and receptacle, in the fruit, and fruit volume, number of seeds/fruit, and total soluble solids content in the fruit pulp, but progeny FE4 presents higher total titratable acidity in the fruit pulp. Narrow-sense heritability estimates were relatively high for all characteristics in which there was variability between progenies, with higher values for number of fruits ha-1 (80 %) and fruit yield (78 %). Relatively high coefficients of genotypic variation (around 20%) were observed for number of fruits ha-1 and fruit yield, with lower values for the other characteristics. There were positive genotypic and phenotypic correlations between fruit diameter (FD) and fruit height, FD and mean fruit weight, and number of fruits ha-1 and fruit yield.

Full textAbstract:
Hass avocado quality varies by origin, season, and production practices. However, there is a lack of methodologies to guarantee that fruit reaching the market has consistent quality. The aim of this work was to identify predictive markers for quality management. Fruit samples produced under different nutrient management, elevation, date-to-harvest, and growth cycle conditions were analyzed. Dry matter, oil content, internal disorders, sensory attributes, minerals, and fatty acids were evaluated as quality variables. The results highlighted soil and weather differences among orchards. Nutrient management practices based on index balancing in some samples increased both productivity and fruit size. High variability was observed in the dry matter related to the age of the fruit at harvest. Ripening heterogeneity was very large in low-elevation orchards where the fruit was picked relatively early. High flesh mineral contents delayed fruit ripening. At low growing temperatures, more oleic and linoleic acids were present in fruits. The sensory texture and taste descriptors were affected by the fruit age and related to the flesh composition. Logistic, PLS-DA, and biplot models effectively represented the variabilities in the ripening pattern, composition, and sensory profile of avocado fruits and allowed the samples to be grouped according to the internal fruit quality.

Abstract: Fruit sorting is an important step in the fruit industry since it ensures that only high-quality fruits are sold. Manual sorting takes time, is labour-intensive, and is prone to human error. The use of a conveyor belt system with machine vision to automate the sorting process can increase the efficiency and accuracy of fruit quality sorting. This study describes the design and execution of a conveyor belt system for sorting fruit quality using machine vision. The approach is intended to sort fruits based on their appearance, such as colour, size, and form. The machine vision system is trained using a collection of photos of variable quality fruits, allowing it to differentiate between high-quality and low-quality fruits. The conveyor belt system is made up of a motor, sensors, and a camera that takes pictures of the fruits as they move along the belt. The machine vision system processes the photos in real time, determining the quality of each fruit and directing it to the right bin. The precision, speed, and efficiency of the system are all measured. The technology looks potential for increasing the efficiency and accuracy of fruit quality sorting in the fruit sector.

Full textAbstract:
This study aimed to evaluate the interference of bagging materials on the incidence of insect larvae and the physical and chemical quality of the guava cv. Paluma in an organic system. The experimental design was in randomized blocks with seven treatments and four replications of 25 fruits each. The bagging materials (treatments) were: nonwoven fabric (TNT), transparent plastic bag, white plastic bag, parchment paper, kraft paper, and non-bagged fruits (control). The titratable acidity (TA), ascorbic acid, soluble solids (SS), SS/TA ratio, fresh mass, fruit diameter, fruit length, appearance, and fruit fly incidence were evaluated. Fruit bagging increased the fresh fruit mass, except the tulle bag, which did not change fruit diameter but increased fruit length. There was a high incidence of fruit flies in the non-bagged fruits (100%) and in those with tulle bags (56.53%), reduced to 2.15% when using parchment paper, and reaching the absence of bored fruits when using nonwoven fabric, transparent plastic, and white plastic bags, materials that provided the highest percentages of marketable fruits. All bagging materials did not change the total titratable acidity content and the SS/TA ratio; however, all of them reduced the content of total soluble solids, except the tulle bag. Fruit bagging with nonwoven fabric and parchment paper increased the content of ascorbic acid. Fruit bagging with parchment paper, plastic bag, and nonwoven fabric are efficient in the organic production of guavas for preventing the infection by insect larvae and maintaining the physical and chemical quality of the fruit.

Applications of 1 or 2 mmol/l SA significantly reduced chilling injury and fruit decay of apricot fruit as well as membrane electrolyte leakage and ascorbic acid content. Fruits treated with SA resulted in high total polyphenolic content, antioxidant capacity and carotenoids content while these parameters significantly decreased in non-treated control fruits. Overall, our results showed that SA prolonged the storability of fruits of three different apricot cultivars during cold storage.

Alternate partial root-zone drying (PRD) irrigation and deficit irrigation (DI) are water-saving irrigation strategies. Here, comparative effects of PRD and DI on fruit quality of tomato (Solanum lycopersicum L.) were investigated. The results showed that the irrigation treatments had no effect on tomato yield but significantly affected several organic and mineral quality attributes of the fruits. Compared to DI, PRD significantly increased the fruit concentrations of Ca and Mg, and fruit juice concentrations of total soluble solid, glucose, fructose, citric and malic acid, P, K and Mg. It is concluded that PRD is better than DI in terms of improving fruit quality, and could be a promising management strategy for simultaneous increase of water use efficiency and fruit quality in tomatoes.

Full textAbstract:
Fruit quality is certainly influenced by biotic and abiotic factors, and a main quality attribute is the external appearance of the fruit. Various possible agronomical approaches are able to regulate the fruit microenvironment and, consequently, improve fruit quality and market value. Among these, fruit bagging has recently become an integral part of fruits’ domestic and export markets in countries such as Japan, China, Korea Australia and the USA because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. Despite increasing global importance, the development of suitable bagging materials and, above all, their use in the field is quite laborious, so that serious efforts are required to enhance and standardize bagging material according to the need of the crops/fruits. This review provides information about the effects of bagging technique on the fruit aspect and texture, which are the main determinants of consumer choice.

Full textAbstract:
The objective of this study was to evaluate the quality of white-fleshed dragon fruit (Hylocereus undatus) at harvest and postharvest to determine fruit quality and the feasibility of harvesting the fruits at different outer fruit color stages. The treatments consisted of four peel color stages – S1 (<25% red peel), S2 (25%-49% red peel), S3 (50% to 75% red peel) and S4 (>75% red peel) – and two evaluation times (at harvest and one day after full red peel color), which corresponded to 1, 3, 5 and 7 days after harvest for the S4, S3, S2 and S1 color stages, respectively. The total, peel and pulp weights, pulp yield, peel thickness, pulp firmness, pH, total soluble solids and peel, scale and pulp colors were evaluated. The peel and scale colors are reliable indicators of fruit quality. It is possible to extend the postharvest shelf life of the fruits by harvesting at the S1 stage, but this negatively affects yield and final quality; the fruits are smaller and less sweet, making harvesting unfeasible at this timepoint. Despite the higher yield and quality of fruits harvested at a more advanced ripeness stage (S4), the postharvest shelf life is considerably reduced. Thus, fruits at stages S2 or S3 should be harvested to obtain higher yield and quality.

A study was conducted to improve fruit yield and quality in nectarine through pruning. Six-year old plants of two cultivars, Silver King and Snow Queen, were given nine different pruning treatments, with three replications, in Complete Randomized Block Design. Results showed that on increasing pruning intensity, fruit yield decreased, while quality of the fruits improved. Best quality fruits in terms of fruit weight and pulp:stone ratio were obtained with 60% thinning-out + 3/4 heading-back, while, maximum fruit surface colour and total soluble solids (TSS) were recorded with 40% thinning-out + 3/4 heading-back. Highest acidity in fruits was recorded with 20% thinning-out + 1/4 heading-back. Among the two cultivars, 'Silver King' exhibited better fruit quality than 'Snow Queen'.

Enhanced fruit quality, plant health, and productivity are major objectives in apple breeding. The undesirable fruit quality traits frequently associated with pest- and disease-resistant cultivars may be related to resource allocation tradeoffs. The objective of the present study was to evaluate the association between insect resistance and fruit quality in apple. The studied ‘Fiesta’ × ‘Discovery’ apple progeny was characterized by reasonable fruit firmness and optimal sugar content and acidity but small fruit size. There was a positive correlation between codling moth (Cydia pomonella) fruit infestation and fruit firmness. Additionally, a positive correlation was detected between shoot infestation by green apple aphid (Aphis pomi), fruit number as well as sugar content. Infestation by the apple leaf miner moth (Lyonetia clerkella), the rosy apple aphid (Dysaphis plantaginea), the leaf-curling aphid (Dysaphis cf. devecta), and the apple rust mite (Aculus schlechtendali) was not significantly related to fruit quality traits. The positive relationship of increased infestation by some pest insects and quality-determining fruit characteristics such as firmness or sugar content points to a possibly increased necessity for plant protection measures in apple cultivars producing high-quality fruits. One possible explanation of higher pest infestation in cultivars producing fruits with high quality is a tradeoff between resource allocation to defensive secondary metabolites or to fruit quality. By identifying a relationship between pest infestation and fruit quality, the present study highlights the need to consider pest resistance when breeding for high-quality apple cultivars. The use of genetic markers for fruit quality and pest resistance in marker-assisted breeding may facilitate the combined consideration of fruit quality and pest resistance in apple breeding programs.

Full textAbstract:
The study was tested the technical feasibility of bagging eggplant fruits during production to protect them against Eggplant fruit and shoot borer (EFSB) following randomized complete block with 6 treatments. Highest number of marketable fruits per plant was produced by imported white bag (12.33), which was followed by butter paper bag (10.67). Maximum aborted fruit was obtained from the imported brown bag (23.33%) and HDPE bag (20.00%). The highest average fruit weight (363.33 g) was obtained from fruits bagged with Imported white, while maximum fruit length and fruit diameter was also produced from imported white bag (15.27 cm and 11.23 cm, respectively). Zero percent damage by eggplant fruit and shoot borer was produced by imported brown bag, imported white bag and butter paper bag, while higher infection was observed in open fruit (control) (17.70 %), HDPE bag (11.70 %). Bagging eggplant fruit produced 38.78 to 58.20 t/ha, while open fruit (control) produced only 35.66 t/ha. The highest calculated fruit yield 58.20 tons/ha was estimated from imported white bag and other bagging fruits were local brown bag (46.74 t/ha), HDPE bag (45.00 t/ha), butter paper bag (43.23 t/ha). The bagging of eggplant fruits with imported white bag and butter paper bag were more effective in reducing damage by eggplant fruit and shoot borer than the other bagging treatments and the control. These two treatments produced higher number of consumers preferred fruit, without negative effects on the color of the skin, fresh weight and fruit abortion, thus resulting in higher economic gains.

[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe and the quality of the produced fruit when the application were made only at planting and 23 days after planting.

Full textAbstract:
Plant-associated microbes can shape plant phenotype, performance, and productivity. Cultivation methods can influence the plant microbiome structure and differences observed in the nutritional quality of differently grown fruits might be due to variations in the microbiome taxonomic and functional composition. Here, the influence of organic and integrated pest management (IPM) cultivation on quality, aroma and microbiome of raspberry (Rubus idaeus L.) fruits was evaluated. Differences in the fruit microbiome of organic and IPM raspberry were examined by next-generation sequencing and bacterial isolates characterization to highlight the potential contribution of the resident-microflora to fruit characteristics and aroma. The cultivation method strongly influenced fruit nutraceutical traits, aroma and epiphytic bacterial biocoenosis. Organic cultivation resulted in smaller fruits with a higher anthocyanidins content and lower titratable acidity content in comparison to IPM berries. Management practices also influenced the amounts of acids, ketones, aldehydes and monoterpenes, emitted by fruits. Our results suggest that the effects on fruit quality could be related to differences in the population of Gluconobacter, Sphingomonas, Rosenbergiella, Brevibacillus and Methylobacterium on fruit. Finally, changes in fruit aroma can be partly explained by volatile organic compounds (VOCs) emitted by key bacterial genera characterizing organic and IPM raspberry fruits.

Full textAbstract:
Bagging regulates the fruit microenvironment and improves the quality and market value of fruits. It is a safe and ecofriendly technique to protect fruits from insect/pest infestation and multiple biotic and abiotic stresses. In the current study, the influence of fruit bagging was evaluated on the development and quality of loquat fruits. Fruits from a healthy loquat orchard (Cv. Zaozhong No.6), located in Fujian, China, were enveloped in paper (T1), aluminum (T2), and aluminum–polyethylene bags (T3), while unbagged fruits were maintained as control (T0). In general, fruit bagging improved fruit quality in terms of fruit physiological and biochemical attributes and protected fruits from physical damage. In particular, aluminum–polyethylene bagging enhanced fruit weight, length, and width by 1.37-, 1.18-, and 1.13-fold, respectively. Loquat fruits bagged with paper bags exhibited the maximum soluble sugar and lowest titratable acid content. Fruits treated with paper and aluminum–ethylene bags showed twofold higher sugar–acid ratio as compared to control. Aluminum–polyethylene bagging caused 66.67%, 55.56%, and 33.33% reductions in skin burn, fruit rotting, and black spot of loquat. The fruits bagged in aluminum and aluminum–polyethylene did not show insect or bird damage, while unbagged fruits had 14.70% and 17.65% insect and bird damage, respectively. Overall, the results suggest that paper, aluminum, and aluminum–polyethylene bagging improved fruit health by 75%, 131%, and 144%, respectively, as compared to control. To delineate bagging type-dependent effects, principal component analysis was performed. Paper bagging was positively correlated with fruit firmness, rotting, soluble sugars, sugar–acid ratio, and proline content. Aluminum bagging was highly associated with improvements in titratable acids, cystine, and methionine. Aluminum–polyethylene bags were correlated with fruit weight, size, peel thickness, edible rate, and certain amino acids.

A new computer vision algorithm for citrus fruit quality classification based on the size of a single tree fruits was developed in this study. The image properties of area, perimeter, and diameter for the citrus fruits were measured by pixels. In order to estimate citrus fruit size in a realistic manner, the ratios of diameter, perimeter and area in pixel values in relation to the actual size of one fruit were determined. The total of 1860 citrus fruits were grouped based on diameter, perimeter, and area in pixels. The results of the grouping of citrus fruits by diameter, perimeter and area were compared with the results of the survey research into citrus fruit size as conducted by the Jeju Citrus Commission. Comparative results reveal that the image of the citrus fruit diameter in pixels demonstrate a more accurate size than the other two pixel values, i.e. perimeter and area.

The objective of this study was to assess the yield and fruit quality of apple produced with a conventional and an organic production systems in Southern Brazil. The orchards consisted of alternate rows from 10 to 12-year old 'Royal Gala' and 'Fuji' apple trees on M.7 rootstocks, grown as slender spindles, on 4x6 m spacing. Eighteen apple trees of each cultivar and management system were randomly selected and assessed for nutrition, flowering, fruit set, yield, and fruit quality during two growing seasons (2002/2003 and 2003/2004). The organic management system resulted in lower concentrations of K, Mg, and N in leaves and fruits, and in smaller fruits for both cultivars, and lower fruit yield for 'Fuji' than from the conventional production system. For both cultivars, fruits from the organic orchard harvested at commercial maturity had a more yellowish skin background color, higher percentage of blush in the fruit skin, higher soluble solids content, higher density, higher flesh firmness, and higher severity of russet than fruits from the conventional orchard. Fruit from the organic orchard had lower titratable acidity in 'Royal Gala', and higher incidence of moldy core and lower incidence of watercore in 'Fuji', than fruit from the conventional orchard. A non-trained sensory panel detected no significant differences for fruit attributes of taste, flavor and texture between fruit from the production systems for either cultivar.

Full textAbstract:
Fruit transpiration or weight loss was measured gravimetrically on eggplant fruits (cv. Classic) at various stages of development. The calyx of some fruits was covered with Vaseline to measure its relative contribution to total fruit transpiration. To evaluate the effect of storage conditions on fruit transpiration and quality, fruit of commercial size (24/37.4 liter box) were stored at either low evaporative demand (10C, 100% RH) or high evaporative demand (20C, 70% RH) for 7 days. After storage period, fruit transpiration and other fruit quality characteristics were determined. The results indicated that ≈70% of total fruit transpiration occurred through the calyx and stem in fruits size-24, where the calyx accounted for ≈10% of total fruit surface area. The surface area of the calyx relative to the total fruit area decreased as fruits developed. There was a positive correlation between evaporative demand in the storage room and fruit transpiration. At a higher evaporative demand, there was a reduction in fruit shelf life, fruits being more withered and less firm as compared to those stored at a lower evaporative demand. Thus, eggplant fruit quality would probably be extended by a reduction in fruit transpiration.

The fruit quality of 15 sweet cherry cultivars (’Canada Giant’, ’Celeste’, ’Chelan’, ’Ferrovia’, ’Germersdorfi Rigle’, ’Katalin’, ’Karina’, ’Kordia’, ’Linda’, ’Regina’, ’Sam’, ’Sandra Rose’, ’Sunburst’, ’Sylvia’ and ’Techlovan’) was studied under super-intensive growing conditions at Nagykutas. We measured the fruit diameter, fruit width, fruit height, stem length and stem weight, fruit and pit weight and the total dry matter content. There were large differences among the cultivars. These differences are due to the genetic characteristics of fruits because all other conditions were the same. For 11 cultivars, we collected fruit samples several times /2-4/. We examined on this cultivars all the above listed fruit quality parameters. When examining these samples, we have gained information how earlier or later than optimal harvest time influences fruit quality.

An experiment was carried out at the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai during 2018 to find out the effect of fruit size on physiological seed quality of cucumber. Variation in fruit size of cucumber results in poor quality seeds. In order to overcome this obstacle fruit grading was done based on weight of fruit to obtain good quality seeds. Harvested fruits of cucumber (Cucumis sativus) were categorized based on the weight into three different groups viz., Big (2.41kg), medium (1.66kg) and small (1.28kg). Observations on fruit and seed quality parameters were recorded. The results revealed that medium sized fruits recorded higher values compared to big and small sized fruits. The number of seeds/fruit recorded higher in medium sized fruit (935 numbers) followed by small (896 numbers) and big (876 numbers) sized fruits. The big, medium and small fruits were recovered to 1.52 %, 1.06% and 0.58% seeds respectively. The physiological quality characters measured in terms of seed germination revealed that seeds of medium sized fruits were recorded higher (80%) followed by seeds of big (82%) and small (65%). The seedling vigour measured through root (17.08cm) and shoot length (14.45cm), dry matter production (0.85g 10 seedlings-1) and vigour index (2522) also proved the superiority in medium sized fruits.

Water stress decreases the quality of fruit by generating reactive oxygen species. Grafting is a technique that can improve the efficiency of crop water usage. This work was performed in order to assess the effect of different water stresses on the commercial and nutraceutical quality of a melon fruit. Cantaloupe melon plants, grown under shade houses were grafted onto a creole pumpkin rootstock and grown with different water stresses (20, 30, and 40 kPa). The grafted melon plants under 30-kPa water stress (G30) showed greater fruit firmness and increased catalase activity. The G30 fruits showed an increase in GPX activity of up to 80% over the non-grafted plants. The GSH was higher in fruits subjected to the 40-kPa water tension. The superoxide dismutase showed a 15% greater inhibition in the fruits from the non-grafted plants. At higher water tensions, the DPPH antioxidant activity decreased, while the vitamin C content increased.

Freshly harvested mango fruit (Mangifera indica L. cv. Nam Dok Mai), were heated at 38 °C for 3 days or heated and then stored at 4 °C for 3 weeks before ripening at 25 °C, then compared with nonheated fruit for quality changes. When not refrigerated, heated and nonheated fruit ripened within 7 days to a comparable quality, although titratable acidity remained higher in heated fruit. The peel of heated fruit was initially yellower in cold-stored fruits, and soluble solids content was initially greater, whereas firmness and titratable acidity were less than that of nonheated fruit during ripening at 25 °C. After cold storage and ripening, heated fruit had a lower incidence of disease and developed less chilling injury than nonheated fruit. Nonheated fruit stored at 4 °C also developed off-flavors whereas the heated fruit did not. Heat treatment did not inhibit ripening but did ameliorate low-temperature injury.

Fleshy fruits are the most demanded fruits because of their organoleptic qualities and nutritional values. The genus Prunus is a rich source of diversified stone/drupe fruits such as almonds, apricots, plums, sweet cherries, peaches, and nectarines. The fruit-ripening process in Prunus involves coordinated biochemical and physiological changes resulting in changes in fruit texture, aroma gain, color change in the pericarp, sugar/organic acid balance, fruit growth, and weight gain. There are different varieties of peaches with unique palatable qualities and gaining knowledge in the genetics behind these quality traits helps in seedling selection for breeding programs. In addition, peaches have shorter post-harvest life due to excessive softening, resulting in fruit quality reduction and market loss. Many studies have been executed to understand the softening process at the molecular level to find the genetic basis. To summarize, this review focused on the molecular aspects of peach fruit quality attributes and their related genetics to understand the underlying mechanisms.

We measured fruit diameter, fruit width, fruit height, stem length and stem weight, fruit and pit weight and total soluble solids content. There were large differences among cultivars in the datas. These differences are due to genetic fruit-characteristics, because all other conditions were the same. We harvested fruits by 3 cultivars two times to check their characteristics on two ripening phases. We examined on these cultivars all the above listed fruit quality parameters. With these data we can be informed about the role of later than optimal harvesting time and how big an effect it has on fruit quality.

Defective fruits are the main reason for worldwide financial catastrophes in agricultural production. It affects both the dependability and quality of the fruits. Post-harvest, quality checking requires a significant amount of time and labor-intensive skill. Automatically identifying fruit quality enables saving time and labor during harvest. Various algorithms have been created using machine learning and image processing methods to detect and categorize fruit quality. A system using Convolutional Neural Networks (CNN) and transfer learning techniques has been developed to enhance the fruit classification process. Two methods are suggested for predicting fruit freshness. One tailored CNN architecture is proposed by modifying the network's parameters to suit the dataset. The second technique utilizes the pre-trained VGG model with transfer learning to assess the freshness of the fruit. The proposed models are capable of differentiating between fresh and spoiled fruit by analyzing the input photos. This research used 70 diverse types of fruit, such as apples, bananas, oranges, and others. The first CNN obtains 98.55% accuracy for heterogeneous fruit dataset while second VGG16 achieves 99.05% accuracy on similar dataset. The plant village global dataset is utilized with various fruit categories. As a result, The VGG16 provides higher accuracy than conventional CNN and other deep learning algorithms.

This research was conducted at farmers’ oranges field in Belantih Village, Kintamani District, Bangli Regency, Bali, and Laboratory of Agriculture Faculty of Warmadewa University. The aim of the study was to know the difference of quality of Siam citrus fruits at different fruit maturity levels during storage period. The experiment used randomized block design. The treatment was fruit maturity, consisting of 4 levels i.e FM1 = harvested 22 weeks after flowering (WAF) with physical appearance of green fruit skin, FM2 = harvested at 24 WAF with green yellowish fruit skin, FM3 = harvested at 26 WAF with yellow-greenish fruit skin, and FM4 = harvested at 28WAF with yellow fruit skin, each repeated 6 times. The results showed, the riper harvested fruit the sweeter the taste, which reflected by the higher total dissolved solids and sugar/acid ratio, but the shelf life was shorter because the fruits were rapidly shrinking and loss of weight and quickly damaged. However, if the fruits harvested too young (before the age of 26 WAF) the quality of the fruits were low reflected by lower of weight per fruit and fruit diameter and decreased the quality of the fruit during storage was faster. Based on the result of this research, to get good quality of Siam Citrus fruit and kept longer on storage the fruit harvest should be done at age 26 WAF with physical appearance characteristic of yellow green fruit skin.

Aim: To study the multivariate analysis, genetic parameters and correlation for post harvest quality and yield traits in tomato.
Study Design: The variability in the twenty genotypes of tomato (Solanum lycopersicum L.) was evaluated for 18 yield attributes and post harvest quality traits using randomized block design and analyzed with multivariate methods.
Place and Duration of Study: Twenty genotypes of tomato augmented from Indian Institute of Vegetable Research, Varanasi were sown during rainy season at Horticulture Research Farm of Banaras Hindu University.
Methodology: The unweighted pair group method of the average linkage (UPGMA) cluster analysis and principal component analysis (PCA) were used to analyze the data. Canonical discriminant analysis showed the contribution of each trait to the classification of the tomato accessions into different cluster groups.
Results: The first seven principal components (PC) explained 87.83% of total variation and has eigen values >1. The traits that mainly contributed for this variation in PC1 and PC2 are fruit yield, plant height, number of flower clusters per plant, number of fruits per plant, days to first fruit set, number of fruits per cluster. High (>20%) genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for number of fruits/cluster, fruit shape index, number of fruits/plant, fruit yield and shelf life. The correlation coefficients of number of primary branches/plant, days to first fruit set, number of flower clusters/plant, number of fruits/cluster, fruit width (cm), number of fruits/plant, fruit weight (g) and lycopene (mg/100 g) were positively and significantly correlated to fruit yield/plant.
Conclusion: Number of flower clusters/plant, fruit weight and number of fruits per plant had contributed for maximum variation. These traits also had high heritability, high genetic gain and significant correlation with fruit yield.

Full textAbstract:
The effects of shoot length, fruit density, thinning patterns, and light levels on crop quality of peach (Prunus persica Batsch.) were investigated. On shoots 50 and 75 cm long, fruits were thinned to produce several distribution patterns, with peaches concentrated in the bottom, middle, or distal portion of the shoot, or uniformly spaced along the shoot at two fruit densities (≈10 or 15 cm between fruit). The lower fruit density on the longer shoots resulted in larger fruits. At the same fruit density, fruits clustered in the distal section of the shoot were smaller, with lower soluble solids concentration (SSC) and a smaller percentage of the exocarp colored red than for the other spacing patterns. Photosynthetically active radiation (PAR) was negatively correlated with the percentage of green exocarp and positively correlated with the percentage of red exocarp. However, the low correlation coefficients (0.45 and 0.50, respectively) indicate that even low light levels can result in substantial red pigment development in peach fruit.

<p class="042abstractstekst"><span lang="EN-US">Gamboge disorder has a detrimental effect on mangosteen. The leakage of the gamboge may result from water availability. Thus, modifying the transpiration of the fruit by bagging might minimize the inappropriate leak of the gamboge produced by the fruit. The study’s objective was to understand the relationship between different fruit positions and bagging treatment on the gamboge disorder in mangosteen. The experiment was conducted on 10-years old trees by tagging young fruits, five replicates with two fruit positions (inside and outside), and bagging treatment (no bagging, transparent and black plastic bagging). The result showed that bagging the fruits inside the canopy does not affect fruit mass. However, bagging with transparent and black plastic of the fruits inside the canopy decreases fruit size. The fruit quality improves by black bagging on the inside canopy fruits. These findings demonstrate that bagging fruits outside the canopy lowers their quality. Black bags used to package fruits inside the canopy improve fruit quality. However, the treatment also causes more fruit to fall from the tree and decreases the nutrient content.</span></p>

Consumer interest in avocado fruit has increased in the last decade in Europe. Nutritional and quality attributes affect the choice of these fruits, whose characteristics must also be maintained in the postharvest period. The preference regarding the feasibility of eating ripe fruits can assure and improve the success of the emerging marketing of avocados. The exposure of fruits to exogenous ethylene (C2H4) treatment can accelerate the process of fruit ripening. The aim of this work was at improving the existing knowledge about the quality traits of avocado cv. Hass fruits at the ready-to-eat stage. The most important qualitative traits (weight loss, dry matter content, hardness pulp, and external and internal fruit colour) were evaluated up to 96 hours, maintaining the fruit at two different temperatures, T1 (+8°C) and T2 (+17°C). A trained sensory panel was conducted at 96 hours to confirm the quality of avocado cv. Hass ripened with exogenous C2H4.

Fruit wines have gained great interest in recent years due to the increasingly diverse demands of consumers for different fruit wines with different colors, flavors, and nutritional values. Some fruits such as blueberry and strawberry are perishable and have a short shelf life. The production of fruit wine reduces fruit losses after harvest and enhances fruit utilization. The production of fruit wine with premium quality is determined by both intrinsic (i.e., genetic background) and extrinsic factors (e.g., yeast and fermentation protocol). This article provides an updated overview on the strategies and technologies aiming to improve the quality of fruit wines. Recent progress in improving fruit wine quality by variety selection, post-harvest treatments, yeast selection, fermentation protocols, fermentation conditions, and aging technologies has been comprehensively reviewed.

Full textAbstract:
The objective of the study was to evaluate some postharvest parameters of fruit quality at seven strawberry cvs., ('Alba', 'Clery', 'Coral', 'Magic', 'Premial', 'Queen Elisa', 'Record') grown at RIFG Pitești, Romania in open field, in the 2016-2018 period. The storage method included three days in normal refrigeration condition (2-4ºC) followed by one day at room temperature (22-24 ºC). The following parameters were determined before and after storage: fruit weight (g), fruit firmness (kgf/cm2), four color indicators (L*, a*, b*, ∆E) and percent of damaged fruits caused by pathogen. Statistically assured differences were recorded between cultivars. 'Premial' cv. proved the lowest fruit weight loss (0.27 g) and also the lowest fruit firmness loss (0.09 kgf/cm2) after storage. 'Alba' cv. had the highest percentage of healthy fruits after storage (86.4%). After four days storage both early cvs.were marketable.

Full textAbstract:
Bitter gourd is a widely consumed cucurbitaceous vegetable rich in several nutrients and phytochemicals. The fruit is also used in traditional medicine systems to cure a variety of ailments. However, bitter gourd fruit has a very short postharvest life of 3-4 days at ambient conditions, due to which it suffers significant loss after harvest. In the present study, with the aim to extend storage life, bitter gourd fruits were packed in corrugated fiberboard boxes along with sachets of potassium permanganate (KMnO4) granules @ 1.0, 2.0 and 3.0 g per kilogram of fruit; while control fruits were packed without KMnO4 sachets. The results revealed that during 8 days of storage at room temperature, fruits packed with 3.0 g/kg KMnO4 sachets had minimum deterioration in fruit quality compared to control, and also weight loss and decay loss was observed lowest. KMnO4 treated fruit @ 3.0 g/kg retained the highest chlorophyll content and lowest accumulation of carotenoid pigments in the fruit skin. These fruits also had maximum soluble solids, ascorbic acid, total phenolics content, antioxidant capacity and minimum accumulation of malondialdehyde up to 8 days of storage than other treatments.

Full textAbstract:
Fruit intake is generally associated with better diet quality and overall health. This report examined the effect of 100% fruit juice (considered a part of total fruit servings) and its replacement with whole fruits equivalents on nutrient intake and diet quality. National Health and Nutrition Examination Survey 2013–2016 data (24-h dietary recall) from adults 19+ years (n = 10,112) were used to assess the diet quality and nutrient intakes and to isocalorically replace with 100% fruit juice intakes whole fruit equivalents in a modeling analysis. About 15.6% adults were 100% fruit juice consumers. Consumers had higher diet quality (10% higher Healthy Eating Index, HEI 2015 score), and higher intakes of energy, calcium, magnesium, potassium, vitamin C and vitamin D than non-consumers. Consumption of 100% fruit juice was also associated with lower risk of being overweight/obese (−22%) and having metabolic syndrome (−27%). Replacing 100% fruit juice with whole fruits equivalents did not affect nutrient intake except for a modest increase (+6.4%) in dietary fiber. Results show that 100% fruit juice intake was associated with better diet quality and higher nutrient intake. Replacement of 100% fruit juice intake with whole fruits equivalents had no significant effect on nutrients except for dietary fiber.

"Calcium Nutrition in Fig Orchards Enhance Fruit Quality at Harvest and Storage." Horticulturae 9, no. 1 (January 16, 2023): 123. http://dx.doi.org/10.3390/horticulturae9010123.
Full textAbstract:
Due to the high perishability of figs, calcium stands out as an important nutrient for orchard management. This study aims to study the pre-harvest applications of calcium chloride in fig orchards. The fig trees were sprayed with 0, 0.5, 1.0, 1.5 and 2.0% CaCl2, and fruits were thereafter stored for 0, 7, 14 and 21 d. The variables analysed were the concentration of calcium in leaves and fruits, weight loss, fruit decay, pectinolytic enzyme activity, and physical and chemical attributes of the fruits; CaCl2 sprays enhanced fruit Ca2+ concentration in leaves (14.03%) and fruits (29.3%) and were effective in reducing polygalacturonase and pectin methylesterase activity, weight loss and fruit decay. Pre-treatment with 1% CaCl2 provided fruits with larger diameters, greater firmness, and higher levels of total phenolic compounds in both fruit peel and pulp. The pre-harvest application at 1% CaCl2 showed to be a promising technique in producing high quality fruits and extended storage by approximately 7 to 10 days. These findings may be useful in planning new cultural practices for fig orchards that produce high-quality fruit with desirable characteristics for growers and consumers.

Full textAbstract:
Plum is the most important fruit crop for cultivation in Serbia. However, a small amount of plum fruit is sold as fresh fruit due to its poor quality. In order to improve fruit quality and obtain regular and high yield chemical blossom thinning agents were applied. The experiment was conducted on seven-year-old plum trees of cultivar `Stanley` which were planted on distance 5x5 m. Ammonium thiosulphate and ethephon were applied in the next treatments: 1) ammonium thiosulphate 1.5% (ATS); 2) ethephon 0.015% (E); 3) ammonium thiosulphate 1.5% + ethephon 0.015% (ATS + E); 4) hand thinning (HT); 5) untreated control treatment (UTC). Chemical thinning treatments were performed once during the phase of full bloom, while hand thinning treatment was performed after the fall of unfertilized fruitlets at the end of May. Parameters analyzed were yield, fruit size, fruit weight, pit weight, fruit firmness, fruit shape index, soluble solids content, total acid content and the amount of harvested fruits per time unit. The obtained results have shown that ATS + E, ATS and HT treatments significantly reduced the number of fruits on the trees compared to the control treatment. However, yield per tree was reduced significantly only in the ATS + E treatment. Other treatments compensated for the smaller number of fruits per tree with a significantly larger fruit size. Since the fruit size was larger on treated trees, the amount of harvested fruits per time unit was significant compared to control treatment. There were no significant differences among the applied treatments in terms of fruit firmness, soluble solids and total acid content.
