Abstract:
The demand for fresh pineapple fruit is currently highest for the MD2 pineapple variety. Continuous efforts are made to enhance the quality of MD2 pineapples, including the fruit skin colour, flesh colour, sweetness, and minimizing sunburn damage. Bagging is one of the pre-harvest methods that can be employed for this purpose. This research aims to find suitable bagging materials that meet the industry's criteria and assess the severity of sunburn in each bagging treatment. A completely randomized design was used in this study, with six different bagging materials and pineapples aged 80 Days After Forcing (DAF). The bagging materials used were the control, blue Polyethylene (PE) bag, white PE bag, black patent bag, paper bag, and the existing cap-shaped bagging technique using recycled paper from banana bagging, as utilized by PT. Great Giant Pineapple. Each treatment involved 120 pineapple samples harvested at 140 DAF. MD2 pineapples without bagging were found to provide the best results according to PT. Great Giant Pineapple's criteria, with green skin colour (1.35%) and uniform yellow flesh (85.62%).

Abstract:
The pineapple is an essential fruit in Taiwan. Farmers separate pineapples into two types, according to the percentages of water in the pineapples. One is the “drum sound pineapple” and the other is the “meat sound pineapple”. As there is more water in the meat sound pineapple, the meat sound pineapple more easily rots and is more challenging to store than the drum sound pineapple. Thus, farmers need to filter out the meat sound pineapple, so that they can sell pineapples overseas. The classification, based on striking the pineapple fruit with rigid objects (e.g., plastic rulers) is most commonly used by farmers due to the negligibly low costs and availability. However, it is a time-consuming job, so we propose a method to automatically classify pineapples in this work. Using embedded onboard computing processors, servo, and an ultrasonic sensor, we built a hitting machine and combined it with a conveyor to automatically separate pineapples. To classify pineapples, we proposed a method related to acoustic spectrogram spectroscopy, which uses acoustic data to generate spectrograms. In the acoustic data collection step, we used the hitting machine mentioned before and collected many groups of data with different factors; some groups also included the noise in the farm. With these differences, we tested our deep learning-based convolutional neural network (CNN) performances. The best accuracy of the developed CNN model is 0.97 for data Group V. The proposed hitting machine and the CNN model can assist in the classification of pineapple fruits with high accuracy and time efficiency.

Abstract:
Lendang Nangka Utara Village is located in the Masbagik Subdistrict, covering an area of 900 hectares. This village is renowned for its abundant natural resources, particularly pineapples. However, an issue observed in this village is the underutilization of these available natural resources. Pineapples, which are an iconic produce of Lendang Nangka Utara Village, should be processed into various products such as pineapple chips, pineapple jam, pineapple candy, pineapple pies, and more. Nonetheless, a majority of the residents in Lendang Nangka Utara Village who have pineapple farms merely sell the fruit without engaging in the production process to create value-added products. The Community Empowerment Real Work Lecture (Kuliah Kerja Nyata) aims to harness the existing resources in Lendang Nangka Utara Village to develop creative and innovative processed products. The chosen sample product for utilizing the available pineapple resources is pineapple pie. The program involves both socialization and training sessions for pineapple pie making. The socialization efforts aim to instill an entrepreneurial spirit within the community of Lendang Nangka Utara Village. Additionally, the pineapple pie training is designed to provide insights to the local community on how pineapples can be transformed into a product with higher market value compared to selling them solely as fresh fruits.

Abstract:
Riau is one of the provinces which is the largest producer of pineapples in Indonesia, reaching 214,277 tons in 2020. Only 53% of pineapples are consumed by the public, and the rest is thrown away. The contents of pineapple skin are water (86.7%) and carbohydrates (10.54%). Pineapple skin also contains quite high levels of sugar and carbohydrates. This can be used for further processing of pineapple skin, so that with a touch of technology and innovation pineapple skin can be converted into processed food products with economic value. One use of pineapple skin is as the main ingredient in making pineapple skin syrup. Pineapple skin syrup produced from processed pineapple skin has a fresh aroma and taste. The aim of this service is to increase the knowledge of SMKS Islamic Inayah Ujungbatu students in utilizing pineapple peels so that pineapple peels, which are usually wasted when processing the fruit flesh, can be used into innovative products with high economic value. The results of the service showed that more than 90% of participants stated that the training provided was very useful for improving their competence and could be used as a reference for independent entrepreneurship.

Abstract:
Pineapple fruit is included in the type of tropical fruit, which is quite popular because it contains a lot of Vitamin C, which is quite high. Pineapple is a local fruit in the Kampar area, this fruit can be consumed directly and become other local processed products. Therefore, the quality of pineapple ripeness must be maintained. The problem that occurs at this time is that the pineapple fruit selection process is still done manually, by looking at it visually, so mistakes can occur in the process of clarifying pineapple fruit identification according to standards. Therefore, it is necessary to research the ripeness of pineapples using the Color Space Algorithm Hue Saturation Intensity (HIS). The variables to be input are based on photos of ripe, half ripe, and raw pineapples using a smartphone camera or DSLR camera with a minimum resolution of 8 MP. Clarifying the results with image processing and Hue Saturation Intensity (HIS) transformation has an accuracy rate of 80% for the 20 image test data. So that the expected results can help pineapple farmers in detecting the level of maturity of pineapple fruit, which is difficult, can minimize errors in determining the ripeness of pineapple fruit

Abstract:
Pineapple is a kind of organic product from the Bromeliaceae family which has the logical name Ananas comosus Merr. Pineapple plants have weathered skin and pointed leaves on top. The taste of new pineapple is a combination of sweet and slightly sharp. Pineapple is high in L-ascorbic acid, which helps cells fight damage, according to the Linus Pauling Organization at Oregon State College. L-ascorbic acid is also useful in managing medical conditions, such as heart disease and joint pain. However, due to the absence of consideration from the regions and local governments regarding pineapple on the island of Sumatra, it has caused several problems, especially data on pineapples related to the advantages, content, and uniqueness of pineapples to be used as pineapples. chaotic and diminishing pineapple production, especially on the island of Sumatra. Therefore, it is important to make a wish to know the assessed amount of Pineapple Organic Product Crop Creation on the island of Sumatra so that the public authorities on the island of Sumatra have endlessly clear references to decide on an approach or make major progress sothat the development of pineapple on the island of Sumatra does not diminish. The method used in making predictions is the FletcherReeves algorithm and is a method in ANN. In this study, the data used was the number of pineapple fruit plants on the island of Sumatra in 2012-2021 obtained from BPS.

Abstract:
Information on methane emission in pineapple cultivation on peatlands is scarce. Methane emission in pineapple cultivation is important as 90% of pineapples are grown on the peat soils of Malaysia. It is essential to determine methane emission in pineapple cultivation because pineapples are Crassulacean acid metabolism plants whose effects on methane could be different from other crops grown on tropical peat soils. Methane emissions from root respiration, microbial respiration, and oxidative peat decomposition were determined in a lysimeter experiment. There were three treatments: peat soil cultivated with pineapple, bare peat soil, and bare peat soil fumigated with chloroform. Methane emissions from peat soil cultivated with pineapple, bare peat soil, and bare peat soil fumigated with chloroform were 0.65 t/ha/yr, 0.75 t/ha/yr, and 0.75 t/ha/yr, respectively. The lower methane emissions are consistent with the general believe that methane emission from cultivated peat soils is lower than those of anaerobic or water logged peat soils. Soil methane emission was affected by nitrogen fertilization under pineapple cultivation but the converse was true for soil temperature nor soil moisture.

Abstract:
Pineapples are a tropical food crop, yet from the late 1600s onwards, they were grown extensively in the northerly latitudes of Europe. The race to produce the first fruit in Europe was won by the Dutch in 1685 but the production of the first British fruits between 1714 and 1716 triggered a mania for growing them and the horticultural developments that this stimulated are described. The advent of hot water heating from 1816 revolutionized pineapple growing and in the Victorian era the production of well-grown pineapples became the crucial challenge that every gardener worth his salt had to master so that fruits could be entered in the prestigious horticultural shows. The Victorian pineapple pit at The Lost Gardens of Heligan, which was restored in 1994, recalls 19th century pineapple growing. A description and evaluation of the cultivation of the pit using traditional Victorian methods, but lacking certain crucial facilities such as tanner’s bark and supplementary heating, is given.

Abstract:
Pineapple has a large demand for plant nutrients and for this reason; fertilization is almost mandatory where the fruit is destined for sale. As consumer demand for organic food grows, organic production and certification is seen as a valuable alternative for smallholder farmers in developing countries. This study sought to investigate the effects of different organic fertilizers on the physical and chemical quality of pineapple (Ananas comosus L.) cultivated in two different ecological zones in Ghana. Organic fertilizers treatments were POME (Palm oil meal effluent), Phos-K (PH), Yara (Y) and combination of Phos-K and POME (PH+P) and Yara + POME (Y+P) in the ratio of 1:1. Soil without fertilizer was control. A farmer field demonstration and an on-station experimental trial were conducted parallel at Nsakyi and at the Biotechnology and Nuclear Agriculture Research Institute (BNARI) research farm, respectively. The experiment was laid out in the Randomised Completely Block Randomized Design (RCBD) with five fertilizer treatments and four replications. Sugar loaf pineapples were harvested at 17 months upon maturity, washed, peeled, and juice extracted for analyzing vitamin C, Total Soluble Solids, pH, Titratable acidity, juice yield and colour. Fruits were weighed with Sartorius scale and percentage weight loss estimated over 15 days. The weight loss of pineapples treated with POME (25.56 ± 0.62 %) from BNARI farm was significantly (p<0.05) higher than all the other pineapple treaments. pH of all pineapple samples significantly (P<0.05) differed for all the different fertilizer treatments for both farms. Phos-K significantly (p<0.05) enhanced the vitamin C content of pineapples from both ecological sites Lightness (L*) and yellowness (b*) for juice of pineapple treated with Phos-K from BNARI farm was significantly (p<0.05) higher, than samples from Nsakyi farms indicating desirable visual appeal for sugar loaf pineapples. Organic fertilizers significantly (p<0.05) influenced the pH, vitamin C and juice yield of pineapples grown in the two different ecological zones. Irrespective of the ecological differences in Nsakyi and BNARI farm sites, the application of Phos-K to pineapple significantly (p<0.05) increased the juice yield which is a desirable quality of pineapple. Thus the application of Phos-K organic fertilizer, better improved the physical and chemical quality attributes of pineapple. However, there is the need to conduct further work on application rate and utilization efficiency of organic fertilizers that will produce maximum pineapple quality and yield.

Abstract:
Located in Muara Enim Regency, Tanjung Baru Village in Lembak Sub-district has an abundance of natural resources, one of which is a pineapple plantation that deserves attention. Thanks to the village's dry soil consisting of sand and low lime content, pineapple cultivation thrives here. In fact, locals often turn to pineapple cultivation for their livelihood. Unfortunately, the sheer number of people owning these plantations has led to a surplus of pineapples, resulting in a drop in prices and lost opportunities for profit. As students, our goal is to foster MSMEs in Tanjung Baru Village through hands-on training on how to make delicious pineapple jam. We strive to provide locals with essential knowledge to effectively utilize pineapple products and delve into researching key ingredients that have the potential to cultivate and trade high-quality pineapples at the best prices. Our goal is to assist the development of MSMEs in Tanjung Baru Village.

Abstract:
Amidst the COVID-19 pandemic, some individuals have turned to functional foods in an effort to bolster their immune systems. One such functional option is prebiotic drinks. These beverages are crafted from fermented sugars, which serve as a carbon source for lactic acid bacteria. To enhance their functional properties, prebiotic drinks often incorporate inulin—a type of prebiotic. Traditionally, these drinks are milk-based, but for those who cannot tolerate dairy, alternatives have emerged. For instance, pineapple-based prebiotic drinks enriched with inulin from mangrove apples have gained popularity. The process involves extracting inulin from mangrove apples and combining it with pineapple to create a probiotic drink. The resulting beverage derives its sweetness from the natural sugars found in pineapples and mangrove apples. Pineapple contains approximately 2.32% glucose, 1.42% fructose, and 7.89% sucrose, while mangrove apples boast 5.08% inulin, 9.67% soluble dietary fiber, and 0.66% FOS. These sugars serve as nourishment for lactic acid bacteria, ultimately stimulating the production of IgG and IgM antibodies. In summary, the combination of inulin-rich mangrove apples and pineapple’s total soluble solids can contribute to fortifying the body’s immune system during the COVID-19 pandemic.

Abstract. In eastern China, pineapple harvesting is a complicated and sometimes dangerous task, and an effective method to harvest pineapples instead of picking them manually has not been developed. In this article, a pineapple picking end-effector based on the physical properties of pineapples (static friction characteristics and compressive properties) was designed. The fingers of the end-effector were used to capture a pineapple in the form of step-by-step movement to help reduce fruit damage and plant damage during picking. The indexes of the evaluation of the pineapple picking performance (fruit damage rate, plant damage rate, fruit fall rate and average picking time) were established, and the picking test was conducted at a pineapple plantation. The temperature effect was analyzed in the morning (19°C) and at noon (35°C). The temperature had no significant effect on the picking performance. The picking performance test showed that the size of the fruit might be the main cause of fruit damage. Throughout the picking test, the fruit damage rate was 5%, the plant damage rate was 0%, the fruit fall rate was 1.7%, and the average picking time of each fruit was 14.9 s.

Abstract:
Burning pineapple residues on peat soils before pineapple replanting raises concerns on hazards of peat fires. A study was conducted to determine whether ash produced from pineapple residues could be used to minimize carbon dioxide (CO2) and nitrous oxide (N2O) emissions in cultivated tropical peatlands. The effects of pineapple residue ash fertilization on CO2 and N2O emissions from a peat soil grown with pineapple were determined using closed chamber method with the following treatments: (i) 25, 50, 70, and 100% of the suggested rate of pineapple residue ash + NPK fertilizer, (ii) NPK fertilizer, and (iii) peat soil only. Soils treated with pineapple residue ash (25%) decreased CO2 and N2O emissions relative to soils without ash due to adsorption of organic compounds, ammonium, and nitrate ions onto the charged surface of ash through hydrogen bonding. The ability of the ash to maintain higher soil pH during pineapple growth primarily contributed to low CO2 and N2O emissions. Co-application of pineapple residue ash and compound NPK fertilizer also improves soil ammonium and nitrate availability, and fruit quality of pineapples. Compound NPK fertilizers can be amended with pineapple residue ash to minimize CO2 and N2O emissions without reducing peat soil and pineapple productivity.

Abstract:
Pineapples are a tropical fruit with high nutritional value and high vitamin and sugar contents. In this study, low-grade pineapples were fermented to produce vinegar using surface culture fermentation (SCF), which involved the addition of dragon fruit juice, to compare the quality and antioxidant activity of different preparations of vinegar. The highest acetic acid concentration (7.35%) was obtained from pineapple vinegar after 20 days of incubation. Vinegar made from mixed pineapple and dragon fruit juice without peel and vinegar with pineapple and dragon fruit juice with peel had acetic acid concentrations of up to 6.20% and 4.50%, respectively. The mixed-fruit vinegar of pineapple and dragon fruit juice with peel displayed the highest antioxidant activity at 210.74 µg/g TE, while no significant difference was found between the other two vinegars (189.52 vs. 187.91 µg/L TE). Notably, the volatile compounds detected in the vinegars were alcohols and esters, which may contribute to the distinct aroma. Overall, the addition of dragon fruit juice with peel to pineapple vinegar increased the phenolic content and antioxidant activity; however, fermentation was slightly slower than that of the other two test materials.

One way to process pineapples, pineapples are classified as highly perishable and rotten foods. For this reason, it is necessary to handle fruit to save the abundance of fruit that occurs during harvest. One example of what the community has done is dealing with the abundant harvest of pineapples by making fruit as a daily snack, namely getting dry fruit products that are ready to eat by making pineapple chips. The production of fruit kiripik is usually done by frying which is done by frying which contains oil which is usually called conventional frying. Therefore, with this oven drying machine, it can help the community in making pineapple chips. The purpose of this study was to determine the moisture content in the manufacture of pineapple chips in a drying oven machine, to analyze the ratio of temperature settings that were set 95 to 110 in the drying process.

Our results show that at eight days of storage, the concentration ofL. plantarumandL. fermentumon pineapples pieces ranged between 7.3 and 6.3 log cfu g−1, respectively, without affecting the final quality of the fresh-cut pineapple. The antagonistic assays indicated thatL. plantarumwas able to inhibit the growth of both pathogens, whileL. fermentumwas effective only againstL. monocytogenes. This study suggests that bothL. plantarumandL. fermentumcould be successfully applied during processing of fresh-cut pineapples, contributing at the same time to inducing a protective effect against relevant foodborne pathogens.

Abstract:
Pineapple mealybug, Dysmicoccus brevipes (Hemiptera: Pseudococcidae), is a significant pest in pineapple production and a key trade barrier. We explored the potential use of ethyl formate (EF) as a methyl bromide alternative for the postharvest fumigation of D. brevipes in imported pineapples. When treated at 8 °C for 4 h, EF fumigation was effective against D. brevipes with LCt99, the lethal concentration × time product of EF necessary to achieve 99% mortality of D. brevipes nymphs and adults at 64.2 and 134.8 g h/m3, respectively. Sorption trials conducted with 70 g/m3 EF for 4 h at 8 °C using 7.5, 15 and 30% pineapple loading ratios (w/v) indicated that loading ratio lower than 30% is necessary to achieve the LCt99 values required to control D. brevipes. In a scaled up trial using 1 m3 chamber, EF fumigation with 70 g/m3 for 4 h at 8 °C with 20% pineapple loading ratio (w/v) resulted in a complete control of D. brevipes treated. There were no significant differences in hue values, sugar contents, firmness, and weight loss between EF-treated and untreated pineapples. Our results suggest that EF is a promising alternative to methyl bromide fumigation for the postharvest phytosanitary disinfection of D. brevipes in pineapples.

Abstract:
Pineapple (Ananas comosus) is one of the five important value chains in Kilifi County and is grown under small scale farming and under rain-fed conditions. There are six distinct pineapple growing areas and CBOs in Magarini namely Changoto, Danisa, Faith, Chamari, Bore-Singwaya and Baricho-Mwanazi. This crop has a big market share but the region can hardly meet the market demand. The pineapples are cultivated in special soils indicated by the presence of certain virgin forests and vegetation types. However, these pineapple farmers face a myriad of challenges that limit full exploitation of the 20,000Ha pineapple growing potential. It is in this regard that a rapid rural appraisal (RRA) study was conducted facilitated by Micro-Enterprise Support Programme Trust with the funding of Danida to establish the current situation on pineapple cultivation in Magarini Sub-County to inform the type of intervention strategies to use. Methodology used involved sampling of 60 farmers out of the total population of 600 pineapple farmers in the six growing areas. The 60 farmers represented 10% sample size. These farmers were selected for focus group discussions and interviews. Methods and tools used for data collection included transect travels across and through the six pineapple growing areas, making observations, taking photographs, meeting key informants and farmers for focus group discussions, and individual interviews. Obtained data was subjected to descriptive analysis. Frequency charts obtained were used to make inferences for discussion. The findings indicated that capital investment required for pineapple establishment was too high. Planting material constituted over 50% of the total investment. Pineapple cultivation is conducted under shift cultivation system, where farmers move to open new virgin forests every 3-4 years since the farmers do not use inorganic fertilizers as contract buyers prefer organically produced fruits. Sokoke (loamy clay) soils were the best soils for pineapple growing unlike Soso (sandy loam) soils or Ngama (clayey) soils. Grabs, beetles, birds, mealy bugs and millipedes were the major pests of pineapples. The MD2 pineapple variety being introduced was susceptible to pests and diseases that caused death of the central apical stem inducing production of tillers (suckers).

Abstract:
Pineapple cultivation in the central zone of Uttar Pradesh represents a dynamic agricultural endeavor, characterized by both challenges and opportunities. This abstract explores the unique factors that farmers face in this region, shedding light on the potential for this tropical fruit's growth and economic contribution. The central zone of Uttar Pradesh experiences a diverse climate, ranging from hot summers to cold winters. Pineapple, originally a tropical fruit, demands consistent warmth [1]. This climatic variability presents a significant challenge for pineapple growers, who must adapt their cultivation practices to ensure optimal growth and yields. Moreover, the soil quality in this region often falls short of the sandy loam and fertility requirements that pineapple plants thrive in [2]. Soil testing and enhancement become critical tasks for farmers looking to establish a suitable environment for pineapple cultivation. Pests and diseases further compound the challenges. Pineapple plants are susceptible to a range of issues, including mealybugs, aphids, and the dreaded fusarium wilt. Effective pest and disease management strategies are vital to maintaining healthy crop yields while minimizing the use of chemical pesticides [3]. Additionally, many farmers in the central zone may lack the requisite technical knowledge and skills needed for successful pineapple cultivation. Access to training and extension services, as well as modern farming practices, becomes essential to enhance agricultural techniques and overcome these challenges. On the flip side, there are significant opportunities awaiting pineapple growers in this region [4]. Pineapples are increasingly sought after for their unique flavor and nutritional value, creating a robust market demand in both local and national markets. Farmers have the potential to tap into this growing demand and enhance their income through pineapple cultivation. Furthermore, integrating pineapple cultivation into existing cropping systems offers an avenue for crop diversification, reducing dependency on a single crop and enhancing overall farm sustainability. Value addition through processing, such as converting pineapples into juice, jam, or canned fruit, allows farmers to expand their product range, increase shelf life, and reduce post-harvest losses [5]. Government support in the form of initiatives and subsidies designed to promote horticulture and agricultural diversification provides a crucial opportunity for pineapple growers to access financial and technical assistance.

Abstract:
ABSTRACT: Brazil is one of the main global producers of pineapple (Ananas comosus L. Merril), with emphasis in the Northeastern region of the country. Pineapple is exposed to several phytosanitary problems, including viruses. Pineapple badnaviruses are caused by two distinct species: Pineapple bacilliform CO virus (PBCoV) and Pineapple bacilliform ER virus (PBErV). The present study aimed to detect possible species of the genus Badnavirus in pineapple samples in Northeastern Brazil, via PCR and sequencing of the RT/RNaseH region. Leaf samples of pineapples were collected in the states of Alagoas, Maranhão, Paraiba and Pernambuco, and subsequently subjected to total DNA extraction and amplification via PCR. Badnavirus positive samples were selected for sequencing. Analysis of pairwise comparisons revealed that all sequences obtained in this work showed an identity greater than 80% with the sequence of the species PBCoV (EU377664), from Australia, fully corroborating with phylogenetic analyzes. These results suggest the widespread of PBCoV in Northeastern Brazil and record the first report of Badnavirus in pineapple culture in Brazil.

Abstract:
Pineapple cultivation in nitrogen deficient and acidic peat soils leads to poor growth, yield, and fruit quality of pineapples. A study was conducted to determine whether clinoptilolite zeolite (CZ) could improve soil nitrogen availability, growth, yield, and fruit quality of pineapples grown in drained peat soils. Laboratory leaching experiments were conducted to determine the effectiveness of CZ in controlling nitrogen loss from peat soils, whereas an ion-exchange resin method was used to determine nitrogen availability in pineapple cultivation. Treatments evaluated were: (i) different amounts of CZ (25, 50, 70, and 100%) + NPK fertilizer, (ii) NPK fertilizer, and (iii) peat soil only. The peat soils with CZ reduced ammonium and nitrate losses because of the sorption of ammonium within the lattices of the CZ via ion exchange. Co-application of CZ (25%) and NPK fertilizers was more effective in increasing soil ammonium availability, whereas the use of CZ (25% to 100%) improved nitrogen uptake and use efficiency, growth, yield, and fruit quality of pineapple because CZ could regulate the availability of nitrogen ions for pineapple uptake. The buffering capacity of CZ increased soil pH and facilitated organic nitrogen mineralization. The co-application of CZ and NPK fertilizers can be used to improve nitrogen availability and pineapple productivity in tropical peat soils.

Abstract:
Pineapple is one of the most economically important fruits in tropical countries, particularly in Thailand. Canned pineapple is currently Thailand’s main exported commodity to many countries, including the United States, Russia, Germany, Poland, and Japan. Fungal diseases are considered a permanent threat to fruits in the pre- and post-harvest stages, leading to considerable economic losses. Fungal disease is one of the primary causes of massive yield losses in pineapples around the world. Colletotrichum species are the most common fungal pathogens affecting different tropical fruits. Although there are many reports regarding Colletotrichum species associated with pineapple, they do not have molecular data to confirm species identification. However, the occurrence of Colletotrichum species on pineapple has not been reported in Thailand so far. In this study, we isolated and identified Colletotrichum fructicola on pineapple in northern Thailand and have proven its pathogenicity to the host. This is the first report of the occurrence of Colletotrichum in pineapple, based on morpho-molecular approaches.

Abstract:
Pineapple fruit is a type of horticultural plant that has the potential to be developed. In the process of pineapple cultivation, it is very susceptible to pests and diseases. Diseases that often attack pineapples such as; wilt disease, stem base rot, fusariosis, bacterial rot, and urethral disease. The process of identifying pineapple diseases is often done manually so it takes a long time. In addition, in the process of controlling pests and diseases, farmers only spray pesticides or other handling techniques that are not suitable for the pests and diseases that attack them. Thus, the treatment is not optimal and has an impact on the emergence of new pests and diseases in pineapple. Currently, computer technology can be used in various branches of science, one of which is artificial intelligence. The expert system is a scientific branch of artificial intelligence that can solve problems. The purpose of this research is to assist farmers in identifying pests and diseases in pineapples so that the control process can be carried out optimally, quickly, and on target. The implementation of an expert system uses the Case Base Reasoning (CBR) method which will produce a diagnostic similarity value and provide recommendations for diseases that attack. This research processes data in the form of symptoms seen in pineapple plants. The test results obtained a percentage of 100%. Thus, the application of the CBR method is very relevant in identifying pests and diseases of pineapple plants.

Abstract:
As a means of adding value to pineapple production and minimising post-harvest losses, sliced pineapples were dried using a Solar Conduction Dryer (SCD) and appropriate thin layer drying models to predict drying were developed whilst the performance of the SCD was also investigated. For the period of the experiment, ambient temperature and temperature in the dryer ranged from 24 to 37 °C and 25 to 46 ℃ respectively. The performance of the dryer was compared to open sun drying using pineapple slices of 3-5 mm in thickness where the slices were reduced from an average moisture content of 85.42 % (w.b.) to 12.23 % (w.b.) by the SCD and to 51.51 % (w.b.) by the open sun drying in 8 hours effective drying time. Pineapple slices of thicknesses 3 mm, 5 mm, 7 mm and 10 mm were simultaneously dried in the four drying chambers of the SCD and their drying curves simulated with twelve thin layer drying models. The Middilli model was found as the best fitted thin layer drying model for sliced pineapples. The optimum fraction of drying tray area that should be loaded with pineapples was also investigated by simultaneously loading 7 mm slices of pineapples at 50, 75, and 100 percent of drying tray area. Loading the slices at 50, 75 and 100 percent of drying tray area gave overall thermal efficiencies of 23, 32 and 44 percent, respectively, hence loading pineapple slices at 100 percent drying tray area was recommended as the best.

Abstract:
In the region that is today Brazil, presence of pineapple in the food of Indigenous peoples was noted early by the Portuguese and other European explorers, who described the presence of the plant in Indigenous gardens and around villages along the Atlantic coast and in the interior. The objective of this paper is to contribute to the ethnobotany and history of pineapple in South America, particularly Central Brazil, based on the first known photographic documentation of the use of pineapple in the diet of an Indigenous society: the Nambikwara in the northwestern region of the State of Mato Grosso, Brazil. The pineapple’s presence in Nambikwara villages immediately caught the attention of the early explorers and fermented Nambikwara “pineapple wine” enjoyed enormous success. The photographic record presented here was produced on the occasion of one of the first scientific expeditions sponsored by the Brazilian government in the early twentieth century, the Commission for the Construction of Telegraph Lines from Mato Grosso to Amazonas (better known as the “Rondon Commission”). All photos presented here were taken by Major Thomas Reis during a visit to the Nambikwara-Mamaindê village, in the Cabixi River region, in northern Mato Grosso, during the expedition undertaken from 1913 to 1914. They show many details of how pineapples (Ananas ananassoides) are processed, including the familiar setting of a child playing beside her working mother. As these four images suggest, unexplored archival materials offer great potential for conducting visual historical ethnobotanical studies of topics that are otherwise invisible in the academic record.

Abstract:
The organic pineapple sub-sector in Uganda has existed for slightly over 10 years. Whereas the sub-sector targets the organic market, slightly more than half of the organic pineapples produced by farmers are sold in this market and the rest is sold to the conventional market. This study aimed at determining the transaction costs that limit the amount of organic pineapples sold by farmers to the organic market. The study also aimed at establishing the relationship between the transaction costs and governance of the transactions between farmers and exporters. Data were collected from 140 organic pineapple farmers and seven organic pineapple export companies. Qualitative methods and econometric methods were used in data analysis. Findings show that there were high asset specificity and uncertainty in organic transactions, which resulted into farmers selling only a proportion of their produce to exporters. Involving farmer in contract formulation, trust, distance to collection centers and high asset specificity increased the proportion of pineapple sold by the farmers while farmers’ experience reduced the proportion sold. There were three forms of governances between farmers and organic exporters; the captive, modular and relational governance. The relational governance had the highest transaction costs, and less proportion of organic pineapples were sold in this governance. The study recommends transaction cost reduction strategies such as organizing farmers in cooperatives, trust building and engaging farmers in contract formulation.

The variations of pre-treatment conducted include control variation (K), immersion in sucrose solution (G), sucrose-citric acid mixture (GS), citric acid (S), thermal blanching (B), and kapur sirih or betel lime solution (KS), with and without freezing process before drying. The S variation resulted in the best shelf life of dried pineapple, lasting 106 days under room conditions using 0.75% citric acid solution. The shelf life of dried pineapple with pre-treatments K, G, GS, B, and K, respectively, were 61, 49, 33, 72, and 20 days. Drying and all types of pre-treatments resulted in a darker colour compared to fresh pineapple. Drying and all types of pre-treatments also yielded higher firmness values compared to fresh pineapple. Freezing prior to drying resulted in a darker colour for dried pineapple compared to unfrozen dried pineapple. Freezing prior to drying also yielded a softer texture compared to unfrozen dried pineapples. According to a group of 32 untrained panellists in the age group of 20-24 years old, the G variation was the most preferred variation of dried pineapple.

Abstract:
Quite a few studies have been conducted to improve the Agrobacterium-mediated transformation of pineapple, which is the second most important commercial tropical fruit crop worldwide. However, pineapple transformation remains challenging, due to technical difficulties, the lengthy regeneration process, and a high labor requirement. There have not been any studies specifically addressing the introduction of GFP-tagged genes into pineapples through Agrobacterium-mediated transformation, which would enable easy, non-destructive expression detection. It would also allow expression localization at the organelle level, which is not possible with GUS a reporter gene that encodes β-glucuronidase or a herbicide resistance reporter gene. Here, we report a method for the introduction of GFP-tagged genes into pineapples through Agrobacterium-mediated transformation. We used embryonic calli for transformation, and plants were regenerated through somatic embryogenesis. In this study, we optimized the incubation time for Agrobacterium infection, the co-cultivation time, the hygromycin concentration for selection, and the callus growth conditions after selection. Our strategy reduced the time required to obtain transgenic plants from 7.6 months to 6.1 months. The expression of GFP-tagged AcWRKY28 was observed in the nuclei of transgenic pineapple root cells. This method allows easy, non-destructive expression detection of transgenic constructs at the organelle level. These findings on pineapple transformation will help accelerate pineapple molecular breeding efforts to introduce new desirable traits.

Purpose The purpose of this paper is to evaluate the shelf-life of minimally processed pineapple when subjected to the use of different edible coatings. Design/methodology/approach The pineapples were peeled and cut into cubes. The gums were prepared by dissolving them in distilled water and then heated to total dissolution. After calcium chloride, citric acid and ascorbic acid and glycerol were added in the solutions. The pieces of pineapple were completely submerged in the respective solutions and then drained. Four treatments were obtained, namely: T1 – control treatment (pineapple without coating); T2 – pectin; T3 – tara; T4 – xanthan. The cubes were stored in PET by 12 days at 4±1°C. Analyzes were carried out of mass loss, pH, titratable acidity, soluble solids, microbiological and sensory analysis. Findings It was possible to observe that the use of evaluated coatings was efficient to maintain the conservation of minimally processed pineapple in all analyzes, when compared with the control sample. The treatment with tara gum showed the best results to those obtained by the other studied gums. Practical implications The study may help small-scale establishments to increase the shelf-life of minimally processed pineapple. Originality/value Tara gum reduced the mass loss, delayed the microbial growth and maintained the sensorial quality of minimally processed pineapples for a longer time.

Abstract:
Fresh-cut pineapple has experienced an increase in demand due to its great health benefits and is rich in vitamins A, B and C. Moreover, pineapple is known as a source of the enzyme bromelain, which has therapeutic applications, such as reducing inflammation, improving digestion and treating osteoarthritis. However, bromelain generally affects the pineapple’s flavour and is less preferred by consumers due to the uncomfortable prickling and tingling sensations it brings. In the present study, two types of gases and their combination, nitrogen (N2) and carbon dioxide (CO2), were used to evaluate their impacts on reducing the tingling and prickling sensations, as well as maintaining the postharvest qualities of fresh-cut pineapple stored at 5°C for 12 days. The parameters being evaluated were the bromelain enzyme activity, flesh colour, ascorbic acid concentration, flesh firmness, soluble solids concentration (SSC), titratable acidity (TA) and sensory evaluation. No significant differences were recorded for all parameters tested. Based on the sensory evaluations, all the attributes, such as colour, aroma, texture, sweetness, sourness, tingling and prickling sensations, and overall acceptance were not affected by the different gases application. Even though no apparent effect was observed, the 30 panellists preferred the aforementioned attributes, except sourness. In conclusion, the fumigation treatments with N2 and CO2 gases were not effective in reducing the tingling and prickling sensations of pineapples cv. Morris.

Abstract:
In mainland China, more than 80% of pineapples (Ananas comosus L.) grown are the cultivar ‘Comte de Paris’. Fruit size is an important commercial trait in crops such as pineapple and it is generally believed that cell number and cell size play an important role during fruit size regulation; however, few cellular biological studies on pineapple fruit development have been conducted. To better understand the regulation of pineapple fruit size, the changes in cell number and cell size during fruit development were analysed. Pineapple cv. ‘Comte de Paris’ fruit were collected every 15 days from 0 to 75 days after the first flower appeared (DAFF), and the flesh of the second (top) and the sixth (base) fruitlets were selected for histological observation. Cell size exhibited a rapid increase up to 60 DAFF, while the cell rapidly proliferated up to 30 DAFF, then slowed down but continued to proliferate. Although grown under identical conditions, ‘Comte de Paris’ pineapples grew to different sizes. The results showed that the cell number, the cell size and the number of fruitlets were correlated with the final fruit size/weight regulation, but that cell number played the most important role.

Abstract:
The date pineapple (Ananas comosus var. comosus) was introduced to Hawaii is not known, but its presence was first recorded in 1813. When American missionaries first arrived in Hawaii in 1820, pineapple was found growing wild and in gardens and small plots. The pineapple canning industry began in Baltimore in the mid-1860s and used fruit imported from the Caribbean. The export-based Hawaii pineapple industry was developed by an entrepreneurial group of California migrants who arrived in Hawaii in 1898 and the well-connected James D. Dole who arrived in 1899. The first profitable lot of canned pineapples was produced by Dole’s Hawaiian Pineapple Company in 1903 and the industry grew rapidly from there. Difficulties encountered in production and processing as the industry grew included low yields resulting from severe iron chlorosis and the use of low plant populations, mealybug wilt that devastated whole fields, inadequate machinery that limited cannery capacity, and lack of or poorly developed markets for the industry’s canned fruit. The major production problems were solved by public- and industry-funded research and innovation in the field and in the cannery. An industry association and industry-funded cooperative marketing efforts, initially led by James Dole, helped to expand the market for canned pineapple. Industry innovations were many and included: selection of ‘Smooth Cayenne’ pineapple as the most productive cultivar with the best quality fruit for canning; identification of the cause of manganese-induced iron chlorosis and its control with biweekly iron sulphate sprays; the use of mulch paper and the mechanization of its application, which increased yields by more than 20 t·ha−1; and the invention of the Ginaca peeler–corer machine, which greatly sped cannery throughput. Nematodes were also a serious problem for the industry, which resulted in the discovery and development of nematicides in the 1930s. As a result, by 1930 Hawaii led the world in the production of canned pineapple and had the world’s largest canneries. Production and sale of canned pineapple fell sharply during the world depression that began in 1929. However, the formation of an industry cartel to control output and marketing of canned pineapple, aggressive industry-funded marketing programs, and rapid growth in the volume of canned juice after 1933 restored industry profitability. Although the industry supported the world’s largest pineapple breeding program from 1914 until 1986, no cultivars emerged that replaced ‘Smooth Cayenne’ for canning. The lack of success was attributed in part to the superiority of ‘Smooth Cayenne’ in the field and the cannery, but also to the difficulty in producing defect-free progeny from crosses between highly heterozygous parents that were self-incompatible. Production of canned pineapple peaked in 1957, but the stage was set for the decline of the Hawaii industry when Del Monte, one of Hawaii’s largest canners, established the Philippine Packing Corporation (PPC) in the Philippines in the 1930s. The expansion of the PPC after World War II, followed by the establishment of plantations and canneries by Castle and Cooke’s Dole division in the Philippines in 1964 and in Thailand in 1972, sped the decline. The decline occurred mainly because foreign-based canneries had labor costs approximately one-tenth those in Hawaii. As the Hawaii canneries closed, the industry gradually shifted to the production of fresh pineapples. During that transition, the pineapple breeding program of the Pineapple Research Institute of Hawaii produced the MD-2 pineapple cultivar, now the world’s pre-eminent fresh fruit cultivar. However, the first and major beneficiary of that cultivar was Costa Rica where Del Monte had established a fresh fruit plantation in the late 1970s. Dole Food Co. and Maui Gold Pineapple Co. continue to produce fresh pineapples in Hawaii, mostly for the local market. All of the canneries eventually closed, the last one on Maui in 2007.

Abstract:
Fruit plants in Kediri Regency are classified as having good economic potential, one of which is pineapple. Pineapple plants in Kediri Regency have differences in productivity in each sub-district. The results of interviews with local farmers indicated that the Supiturung Micro Watersheds in Plosoklaten District had low pineapple productivity and were not yet optimal. Therefore, this study aimed to determine the factors causing differences and less optimal productivity of pineapples in the Supiturung Micro Watersheds and analyze the land suitability assessment of pineapple plants in the region. This study used a survey method with a physiographic approach to 10 Land Map Units (LMU) and determined 20 observation points as representatives. Data analysis was performed through correlation and multiple regression tests with the stepwise method to determine the land characteristics that most significantly affected pineapple productivity. Modification of the suitability class and modification of the criteria was carried out utilizing boundary line analysis, with class boundaries according to FAO (1976), namely class S1 (80-100%), S2 (60-80%), S3 (40-60%), and N (<40%) of the potential productivity. The land suitability evaluation results of pineapple plants in the Supiturung Micro Watersheds were included in land suitability classes S2, S3, and N. Based on the stepwise method analysis, the texture is a significant characteristic affecting the productivity of pineapples (p <0.05) with a correlation coefficient value of 0.838. The modification of land suitability criteria with boundary line analysis resulted in changes in one land characteristic, namely soil texture S2, S3, and N. Initially, the rough class included in the N class was changed to S2 level along with the slightly rough level.

Abstract This study aims to determine consumer characteristics and attributes, and level of pineapple fruit, which are consumers’ preferences in Labuhan Batu District, North Sumatra Province. The largest peatland is on the east coast, namely in the Labuhan Batu District area of 192 thousand ha. Some research results support that pineapple is tolerant of high soil acidity levels, adaptive to peat swampland that is tolerant of pH 3‒4. Based on this, pineapple is a potential plant in Labuhan Batu District, so sustainable pineapple cultivation is needed. By understanding the characteristics, attributes of pineapple level, from consumer preferences, it is hoped that marketing and determining sales strategies can be adjusted to market demand: methods, conjoint analysis. The characteristics of the consumers used are gender, age, education level, type of work, family income per month, number of family members, and purchase frequency for attributes, taste, size, taste, color, and texture. The results of the study, the characteristics of age 25‒44 are consumers who consume the most pineapples. The combination of pineapple fruit that consumers like, fruit with a sweet taste, large size, strong taste, soft and smooth texture, and yellowish-green color. This can be considered in determining the target market and marketing strategy for pineapple in Labuhan Batu District, North Sumatra Province.

Abstract:
Pineapple is a fruit commodity that is Indonesia's flagship. This is because pineapple is a fruit that has the highest export volume in Indonesia. To obtain pineapples with perfect ripeness, generally manually selected, this becomes inefficient if large numbers of pineapples are selected. So, in this study, an image processing system will be developed that can classify pineapple ripeness based on its image. In this study, the color feature extraction used is feature extraction based on hue and saturation values. Color feature extraction with hue and saturation is used to obtain various information from the colors in the image so as to facilitate the identification process. Furthermore, Linear Discriminator Analysis will obtain optimal projections to be able to enter spaces with smaller dimensions by performing pattern recognition that can be separated so that they can be grouped based on boundary lines obtained from linear equations. Based on the results of the accuracy test, the accuracy rate reaches 83%, it is in the good category

Abstract:
Pineapple waste accounts for a significant part of waste accumulated in landfill which will further contribute to the release of greenhouse gases. With the rising pineapple demands worldwide, the abundance of pineapple waste and its disposal techniques are a major concern. Exploiting the pineapple waste into valuable products could be the most sustainable way of managing these residues due to their useful properties and compositions. In this review, we concentrated on producing useful products from on-farm pineapple waste and processing waste. Bioenergy is the most suitable option for green energy to encounter the increasing demand for renewable energy and promotes sustainable development for agricultural waste. The presence of protease enzyme in pineapple waste makes it a suitable raw material for bromelain production. The high cellulose content present in pineapple waste has a potential for the production of cellulose nanocrystals, biodegradable packaging and bio-adsorbent, and can potentially be applied in the polymer, food and textile industries. Other than that, it is also a suitable substrate for the production of wine, vinegar and organic acid due to its high sugar content, especially from the peel wastes. The potentials of bioenergy production through biofuels (bioethanol, biobutanol and biodiesel) and biogas (biomethane and biohydrogen) were also assessed. The commercial use of pineapples is also highlighted. Despite the opportunities, future perspectives and challenges concerning pineapple waste utilisation to value-added goods were also addressed. Pineapple waste conversions have shown to reduce waste generation, and the products derived from the conversion would support the waste-to-wealth concept.

Changing the ingredients also can change the properties of the bread. In this study, bread was made using rice flour and sourdough. Sourdough with Lactic Acid Bacteria (LAB) and yeast can also be added with pineapple starter to help microbiota growth. The study aimed to determine the amount of microbiota produced from sourdough with pineapple addition and its effect on the texture of rice flour bread. Pineapples with water and sugar were fermented to make pineapple starter. Pineapple starter is then used in sourdough making and fermented around 3-6 days. The mature sourdough was used in bread making. The addition of pineapple, in the form of a starter, made the pineapple sourdough (PS) have lower pH and higher titratable acidity (TA), total Lactic Acid Bacteria (LAB), and total yeast than sourdough without the addition of pineapple starter or wheat sourdough (WS). The pH and TA of PS at the peak were 3.25 and 2.67 mL of NaOH. The total LAB of PS at the peak was 9.27 Log CFU/g, and the total yeast was 9.30 Log CFU/g. PS reached its peak on the third day, while wheat sourdough (WS) reached it on the sixth day. The pineapple sourdough bread (PSB) had the lowest specific volume, and the highest texture properties compared to control bread (CB) and wheat sourdough bread (WSB), but there is no significance different. The addition of pineapple starter can fasten the fermentation time of sourdough and made the bread less brittle than CB.

Abstract:
Pineapple (Ananas comosus) is widely consumed and appreciated not only due to its taste and aroma and to its nutritional and antioxidant properties, including its vitamin C and phenolic contents. In an attempt to explore new antioxidant leads, pineapple waste is often neglected in the pineapple industry. Fruit processing has considerably higher ratios of by-products and pineapple by-products are not exceptions as they consist basically of the residual pulp, peels, stem, and leaves. Pineapple waste is a by-product resulting from canning processing of pineapple that produces about 35% of fruit waste and leads to serious environmental pollution. The objective of this study is to determine whether different varieties and parts of pineapple waste (peel, core, crown, and stalk) can affect and give the highest amount of natural antioxidant activity. In this study, the antioxidant activities of different parts of three pineapples (N36, Madu, and MD2 were measured using the DPPH method. Methanol solvent has been used for extraction and various parts of pineapple were used to determine the effect of different plants on antioxidants. The samples were determined by using an ultraviolet (UV) spectrophotometer. The result for scavenging activity (DPPH) indicates Madu variety displayed high scavenging activity compared to MD2 and N36 varieties. Madu varieties demonstrated a significant free radical scavenging ability where their crown has IC50 and cores are merely IC50 at 175 ppm and 500ppm. The MD2 crown also demonstrates IC50 at 275 ppm. The results suggest that Madu varieties comprised of the crown of pineapple studied may be useful as potential sources of natural antioxidants.

Pineapples have been associated with outbreaks of Escherichia coli and Salmonella. Little is known about the behavior of E. coli O157:H7 and Salmonella on cut pineapple. The objectives of this study were to evaluate the fate of E. coli O157:H7 and Salmonella on fresh and frozen cut pineapples and the influence of acid adaptation on Salmonella survival on fresh cut pineapple at ambient storage (23°C). Cut pineapples were spot inoculated with a four-strain cocktail of E. coli O157:H7 or a five-strain cocktail of Salmonella. Inoculated samples were air dried, placed in containers, and stored at 4, 12, 23, and −20°C. Samples were stomached and then enumerated on nonselective and selective media at days 0, 1, 3, 5, 7, 10, 14, 21, and 28 (4 and 12°C); 0, 1, 3, 5, and 7 (23°C); and 0, 7, 14, 21, 28, 60, 90, 120, 150, and 180 (−20°C). E. coli O157:H7 and Salmonella inoculated onto pineapple did not grow but survived for the shelf life at each temperature, with improved survival at lower temperatures. E. coli O157:H7 and Salmonella can survive on frozen cut pineapples for at least 180 days. Acid adaptation of Salmonella did not allow growth and did not increase survival. Fresh and frozen cut pineapples are potential vectors for E. coli O157:H7 and Salmonella transmission and preventive procedures should be implemented during production and postharvest processing.

Abstract:
This study compared the quality and storage characteristics of four pineapple varieties to select those displaying adequate storage resistance and those suitable for freshly cut processing. Four varieties of pineapple, namely Tainong No.16, Tainong No.17, Tainong No.11, and Bali, were used to analyze the quality differences in freshly cut pineapple during storage by measuring the quality, physiological indicators, and total microbial count. The results indicated that the nutritional quality and storability of freshly cut pineapples differed significantly among the varieties. During refrigeration at 4 °C, Tainong No.11 and Bali displayed the shortest storage period of 4 d, while Tainong No.17 and Tainong No.16 presented storage periods of 5 d and 6 d, respectively. A sensory evaluation indicated that the Tainong No.16 variety was superior in terms of consumer preference, while the Bali slices were generally rated lower than the other cultivars. Additionally, the sensory properties, weight loss, firmness, and ascorbic acid (AA) content of Tainong No.16 changed the least during storage, with values of 60.75%, 6.48%, 75.15%, and 20.44%, respectively. Overall, the quality order of the four varieties of freshly cut pineapples during storage was: Tainong No.16 > Tainong No.17 > Tainong No.11 > Bali. Moreover, two-way ANOVA showed that the main effect of variety and storage time on the storage quality of fresh-cut pineapple was significant (p < 0.05). The interaction effect of variety and storage time on other quality characteristics of fresh-cut pineapple was significant (p < 0.05) except for Titratable acid (TA) and AA. In conclusion, Tainong No.16 displayed higher storage potential than the other varieties. The results of this work provide application possibilities to promote the successful processing of pineapple cultivars as freshly cut produce.

Abstract:
Sugihwaras Village is a village located in Ngancar District, Kediri Regency. The Sugihwaras Village area includes plantation areas, forestry areas and the Mount Kelud Tourism Area, which means that some economic activities take place in the agricultural and tourism sectors. A well-known agricultural commodity is pineapple with a typical mainstay product, namely "kelud “Madu” pineapple". The superiority of commodities and the implementation of tourism activities in the Mount Kelud Tourism Area has created new job opportunities, namely Kelud “Madu” Pineapple Traders. In practice, Kelud “Madu” pineapple traders are part of Micro, Small and Medium Enterprises (MSMEs) and as an aspect of Tourism Amenities to support tourism activities in the Mount Kelud Tourism Area. The Kediri Regency Government also supports the potential of “Madu” pineapple in Sugihwaras Village by holding a Pineapple Festival to develop and commercialize the potential of kelud “Madu” pineapple. However, the government's objectives are still not in line with the conditions of MSMEs selling kelud “Madu” pineapples. Therefore, this research seeks to examine marketing management by Kelud “Madu” pineapple traders as supporters of the Mount Kelud Tourism Area. This research uses a qualitative method with an exploratory descriptive approach. Data collection techniques use interviews, observation and documentation. Data analysis consists of data collection, data condensation, data presentation, and drawing conclusions. The research results show that marketing by kelud “Madu” pineapple traders is considered to be quite good in terms of potential, personal, operational, relationship and interaction management. The obstacles encountered by kelud “Madu” pineapple traders are related to the provision of facilities, high purchasing prices, and declining sales. Efforts made by the government include organizing festivals and community training, but there is a need for capital assistance for traders.

Abstract:
Fresh pineapple is an excellent source of vitamin C and there is a big demand for organically produced sugar-loaf pineapples in Europe. However, due to its high moisture content and high perishability, transportation over long distances is difficult and require cold storage conditions. The main objective of this research was to assess the quality properties of organic and conventional sugar loaf pineapples under cold storage conditions over a 21 – day period. Conventional pineapples were harvested from Albe Farms in the Eastern region and organic pineapples from Ali farms in the Central regions of Ghana. The fruits were allowed to cool to room temperature before storing at 1°C. Physical and chemical properties of the fruits were determined at days 0, 7, 14 and 21, using standard methods. Conventional sugar-loaf pineapples were larger, but had lower dry matter, soluble solids and vitamin C, than organic pineapples. The weight, translucency and pH of the two categories of pineapples were similar. No significant loss in weight, lengths and crown characteristics were observed after the storage period. Translucency increased from <25% to a range of 50 – 75% by the end of the storage period in both organic and conventional fruits. While no clear trend was observed in the soluble solids content and pH during storage of both organic and conventional sugarloaf pineapple, total titratable acidity increased marginally and vitamin C levels dipped over the 21-day storage period. The trends in acidity, vitamin C and translucency suggest that it is possible to store both conventional and organic sugarloaf pineapple for 21-day storage period at 1 °C. This implies the possibility of shipping both organic and conventional sugarloaf pineapples to destinations requiring sea freighting.
