Gathambiri, CW, WO Owino, S. Imathiu, and JN Mbaka. "Postharvest losses of bulb onion (Allium cepa L.) in selected sub-counties of Kenya." African Journal of Food, Agriculture, Nutrition and Development 21, no. 02 (March 24, 2021): 17529–44. http://dx.doi.org/10.18697/ajfand.97.20145.
Full textAbstract:
Inappropriate postharvest practices such as unsuitable harvesting methods and inadequate curing in bulb onion lead to losses. Postharvest losses in bulb onion contribute to food and nutrition insecurity. Although Kenya has suitable environmental conditions for bulb onion production, its productivity is low, which is attributed to pre-and postharvest factors. Information on bulb onion postharvest losses and their causes in the country is scanty which limits the development of postharvest losses reduction strategies. Therefore, this study was carried out in three major bulb onion growing sub-counties of Kenya namely Mt.Elgon, Buuriand KajiadoEastto determine postharvest practices, causes, and factors influencing postharvest losses of bulb onion. A multi-stage sampling design was used to select the study areas and a total of 166respondents were randomly selected. Face-to-face interviews were conducted using a structured questionnaire to collect information on postharvest handling practices, postharvest loss levels, and their causes at farm level. Data were subjected to descriptive and logistic regression analysis using Statistical Package for Social Scientists(SPSS) software version 2.0. Results indicated that 68% of the respondents were males and with an average age of40 years in the three sites. Forty-eight percent of the respondents used leaves toppling, and 25% used drying of upper leaves as maturity indices. About 42% of the respondents used machete (panga) as a harvesting tool which significantly (P<0.05) influenced postharvest losses. Seventy seven percent of the respondents indicated that up to 30% of postharvest losses occurred at farm level. Forty percent of the respondents indicated that bulb onion rots caused 10 % loss at farm level. The level of education and mode of transport (bicycles and donkeys) significantly (P<0.05) influenced postharvest losses. It was concluded that the postharvest losses at farm levelwas30%andwere mainly caused by rotting. Socio-economic characteristics and postharvest handling practices influenced bulb onion losses at farm level. Development of postharvest losses reduction strategies on bulb onions focusing on alleviating rotting through appropriate postharvest handling practices at farm level was recommended.

Full textAbstract:
Postharvest loss reduction has received attention in many policy documents across nations to ensure global food security, particularly in developing countries. Many researchers have examined various options for reducing postharvest losses. We contribute our quota to this scientific discourse by using a different approach. We argue that the human element of managing postharvest loss is central and therefore poses the question of what are the characteristics of the farmer who manages postharvest losses better. We examine this question by using a cross section of yam farmers in the Zabzugu district in Northern Ghana and generate a proportional variable called postharvest management, which measures how effective a farmer works to reduce storage losses. We then use a fractional logistic regression model to examine the determinants of postharvest management. A significant result is that subsistence farmers manage postharvest losses better than commercial farmers. Characteristically, the farmer who effectively manages postharvest losses is a young, subsistence farmer, living in or close to a district capital with fewer household members, has attained formal education, and produces more yam. Efforts to reduce postharvest losses require the provision of access roads to remote towns or providing effective storage techniques and training on postharvest management practices.

Full textAbstract:
Purpose The purpose of this paper is to develop a straightforward method to quantify volume and value of postharvest losses in the tomato postharvest value chain in Nepal and estimate the monetary loss shouldered by value chain actors. Design/methodology/approach The study combines interview data to quantify volume and prices with produce sampling to quantify quality losses, and does this at four nodes of the tomato value chain in Nepal: farmers, collectors, wholesalers, and retailers to estimate volume and value of postharvest losses. Findings Almost one-fourth of the total tomato harvest weight that enters the value chain is lost before it reaches consumers, and other one-fifth is traded by the value chain actors at reduced price due to quality damage. The total volume of postharvest loss (weight and quality loss) is not the same for all value chain actors and the average monetary loss ranges from 4 percent of gross revenues for farmers to 12 percent for wholesalers. Practical implications A standard method to account for both physical weight losses and quality losses of horticultural produce is lacking in estimates of the monetary value of postharvest losses for horticultural crops. Knowing such losses is essential for postharvest technology generation, promotion, and adoption. This study provides a framework that can be adopted and improved in future loss assessment studies for estimating the volume and value of postharvest losses in a horticultural value chain. Originality/value The uniqueness of the method used in this study is that it combines interview data to estimate price and volume with produce sampling to quantify quality losses, and does this at four nodes of the value chain: farmers, collectors, wholesalers, and retailers. This method could become a standard approach for assessment of postharvest weight and quality losses and to estimate the monetary value of total postharvest losses in the value chain for horticultural crops.

Full textAbstract:
Tomato production can serve as a source of income for most rural and periurban producers in most developing countries of the world. However, postharvest losses make its production unprofitable in these parts of the world. Postharvest losses in tomatoes can be as high as 42% globally. Postharvest losses in tomatoes can be either quantitative or qualitative. Even though emphasis in crop research nowadays is increasing shifting from quantity to quality of produce, there is still little improvement in the quality of commercially produced tomato varieties, hence resulting in high quality losses. From the study it was discovered that the postharvest quality status of tomatoes partly depended on some preharvest practices carried out during production. Some of these factors are fertiliser application, pruning, maturity stage, cultivar selection, and irrigation. Using best postharvest handling practices or factors such as temperature, relative humidity, gases in storage, postharvest calcium chloride application, and physical handling procedures to maintain the quality after harvest was also critical. It was concluded by this study that understanding and managing both preharvest and postharvest factors properly will reduce the postharvest quality losses in tomatoes.

Purpose – The purpose of this paper is to evaluate the banana industry in Zimbabwe focusing on postharvest losses along the value chain (VC). Design/methodology/approach – The study evaluated the banana industry in Zimbabwe focusing on postharvest losses along the VC. Findings – Total postharvest losses for 2011-2012 were estimated to be 24-27 per cent of total production with a minimum economic loss of USD69,983/annum/firm, and a total loss of more than USD500,000/annum between the VCs analysed. The bulk of the losses occurred at farm level during handling and transportation. The major factors contributing to banana postharvest losses were: unreliable transport, poor communication and coordination between producers and processors; lack of or inefficient temperature management and poor sanitation. Practical implications – The study identified production capacity, quality and branding as opportunities and challenges in the banana industry. Currently, there is a 40 per cent unmet local demand for bananas and hence there are no exports. If modern banana handling systems are employed and more research and development is carried out along the VC, postharvest losses can be reduced significantly, resulting in increased income and potential expansion of the industry. Originality/value – This is the first known attempt to analyse the banana VC in southern Africa and quantify postharvest losses.

Full textAbstract:
Postharvest losses of horticultural perishables between the production and retail distribution sites are estimated to range from 2% to 23%, depending on the commodity, with an overall average of about 12% of what is shipped from U.S. production areas to domestic and export markets. Estimates of postharvest losses in developing countries are two to three times the U.S. estimates. Losses in dried grains, legumes, nuts, fruits, vegetables, and herbs and spices range from 1% to 10%, depending on their moisture content, temperature and relative humidity of transport and storage facilities, and protection against pathogens and insects. Reduction of these losses can increase food availability to the growing population, decrease the area needed for production, and conserve natural resources. Strategies for loss prevention include use of genotypes that have longer postharvest-life, use of an integrated crop management system that results in good keeping quality of the commodity, and use of the proper postharvest handling system that maintains quality and safety of the products. Biological (internal) causes of deterioration include respiration rate, ethylene production and action, rates of compositional changes, mechanical injuries, water loss, sprouting, physiological disorders, and pathological breakdown. The rate of biological deterioration depends on several environmental (external) factors, including temperature, relative humidity, air velocity, and concentrations of carbon dioxide, ethylene, and oxygen. Socioeconomic factors that contribute to postharvest losses include governmental regulations and policies, inadequate marketing and transportation systems, unavailability of needed tools and equipment, lack of information, and poor maintenance of facilities. Although minimizing postharvest losses of already produced food is more sustainable than increasing production to compensate for these losses, less than 5% of the funding of agricultural research is allocated to postharvest research areas. This situation must be changed to increase the role of postharvest loss reduction in meeting world food needs.

Full textAbstract:
Current postharvest activities in the sesame value chain are prompting colossal losses, which reduce overall global productivity. This review portrays losses in sesame during various processing stages, from grain harvesting to marketing and transformation of crop seed into oil. Such losses in sesame not only reduce yield but also have an impact on the economy of its production territories. The loss in productivity is because the majority of farmers don't use adequate harvesting, packaging, or handling technologies to manage on-farm produce. Also, there is a lack of knack for minimizing postharvest losses. Therefore, the study penlights the inevitability of increasing production by raising productivity and quality while giving mitigation strategies to reduce postharvest losses. Elevating standardized productivity with accurate postharvest management is the only substitute for the gap between the global productivity average and the overall production potential of sesame.

Full textAbstract:
The study examined the nature and causes of postharvest losses incurred by formal and informal traders in Mutare urban. A survey was conducted where questionnaires were administered to various respondents in the formal and informal sector of fruits and vegetables. The research study assessed the profitability of trading in fruits and vegetables to formal and informal traders. It also assessed traders’ perception of the losses of fruits and vegetables and further determined the possible ways of reducing these postharvest losses so as to enhance profitability in the sector. The study from a sample of 34 respondents revealed that both formal and informal traders experience losses during storage and transportation of goods. Losses incurred during storage were due to the unavailability of proper storage facilities specifically to informal traders. Furthermore, postharvest losses were also resulting from excessive exposure of crops to sunlight, poor packaging, poor carrying containers, attacks by insect pests as well as microbial or disease attacks. Postharvest losses affect profitability and growth of the fruits and vegetables sectors. There is need for farmers to improve on the quality of their produce and harvesting practices as emphasized by traders as they suffered losses as a result of poor quality goods supplied. Further postharvest practices should be improved by traders with special emphasis on adequate storage, handling and proper transportation of goods.

Purpose – The purpose of this paper is to quantify the incidence of postharvest losses of cabbage at retail purchase and during consumer simulated storage. Design/methodology/approach – Physical losses, changes in quality and nutritional value were determined using produce from three different retail outlets in South Africa. Economic losses and the environment impact associated with postharvest losses of cabbage were estimated. Findings – After seven days in storage, high incidence of postharvest losses occurred, ranging from 12 per cent under cold storage to 46 per cent under ambient conditions. These losses were equivalent to over R10 million (∼US$1 million) per annum, while the equivalent wasted fresh water was estimated to be sufficient to meet the needs of over 217,000 per annum. Research limitations/implications – Study was only conducted in one town and to get the real impact of the losses the research should cover a wider coverage area. Originality/value – Cabbage is one of the most widely consumed vegetables globally and this is the first research effort to quantify the magnitude of postharvest losses. A multi-parameter approach was applied to estimate the socio-economic and environmental impacts of losses.

Crimson Seedless) along the Supply Chain and Associated Economic, Environmental and Resource Impacts." Sustainability 13, no. 8 (April 16, 2021): 4450. http://dx.doi.org/10.3390/su13084450.
Full textAbstract:
High incidence of postharvest losses is a major challenge to global food security. Addressing postharvest losses is a better strategy to increase business efficiency and improve food security rather than simply investing more resources to increase production. Global estimates show that fruit and vegetables are the highest contributors to postharvest losses and food waste, with 45% of production lost. This represents 38% of total global food losses and waste. However, the lack of primary data on postharvest losses at critical steps in the fruit value chain and the unknown economic, environmental and resource impacts of these losses makes it difficult to formulate mitigation strategies. This paper quantifies postharvest losses and quality attributes of ‘Crimson Seedless’ table grapes at farm and simulated retail levels. Table grapes were sampled from four farms in the Western Cape Province of South Africa, the largest deciduous fruit production and export region in Southern Africa. Mean on-farm losses immediately after harvest was 13.9% in 2017 and 5.97% in 2018, ranging from 5.51% to 23.3% for individual farms. The main reason for on-farm losses was mechanical damage (7.1%). After 14 days in cold storage (−0.3 ± 0.7 °C, 81.3 ± 4.1% RH), mean grape losses were 3.05% in 2017 and 2.41% in 2018, which increased to 7.41% in 2017 and 2.99% in 2018, after 28 days. After 10 days of further storage under simulated market conditions (5.4 ± 0.6 °C, 83.7 ± 2.9% RH), fruit losses were 3.65% during retail marketing and 4.36% during export. Storing grapes under ambient conditions (25.1 ± 1.3 °C and 46.6 ± 6.0% RH) resulted in a higher incidence of losses, increasing from 7.03 to 9.59 and 14.29% after 3, 7 and 10 days, respectively. The socioeconomic impacts of these postharvest losses amounted to financial losses of over ZAR 279 million (USD 17 million according to the conversion rate of 20 October 2020) annually, and this was associated with the loss of 177.43 million MJ of fossil energy, 4.8 million m3 of fresh water and contributed to the emission of approximately 52,263 tons of CO2 equivalent.

Fruit cullage due to postharvest-expressed diseases and disorders of `Anjou' pear amounted to $1.4–2.4 million annually to northwest growers in 1991–93. Fungal diseases, including Penicillium spp., Botrytis cinerea, and Mucor spp. accounted for the majority of losses. Scald, skin speckling, and scuffing are listed by packinghouse managers as major contributing disorders. A 3-year study has examined reasons for losses and methods to reduce losses through improved postharvest handling. Maturity at harvest, fruit nutrient status, time of packing, temperature management, and improved handling practices provide the basis for cullage.

Abstract Despite the goal set in 1975 by the Seventh Special Session of the U.N. General Assembly for a 50% reduction in postharvest losses to be achieved by 1985, little postharvest horticultural research has been published by lesser developed countries (LDCs), where losses are assumed to be high (7, 9, 12). An exception is the work of the ASEAN Postharvest Horticulture Training and Research Center in the Philippines. Interest in postharvest research, however, runs keen among LDC researchers. A recent survey of foreign alumni of the Dept. of Horticulture at Michigan State Univ. showed that the course most cited as the one they “would take today” was postharvest physiology (1).

Mechanical intervention in rice (Oryza sativa L.) postharvest operation especially harvesting, threshing and carrying is increasing due to shifting labour from agriculture to non-agricultural sector. It was hypothesized that mechanical intervention in rice postharvest operation will increase the postharvest losses. A two-year study (2008-2010) was conducted during Aus, Aman and Boro seasons in six locations of sadar upazila at Gazipur district to test the hypothesis. The widely used varieties of BR11, BR23, BR26, BR27, BRRI dhan28, BRRI dhan29 were used to assess the losses during harvesting to drying. In the study areas, farmers common practices (harvesting paddy by sickle; transportation by head, shoulder and power tiller operated trolley; threshing by open drum and close drum thresher; cleaning by traditional cleaning device kula and winnower and sun drying) were used to assess the postharvest losses. The average postharvest losses from harvesting to drying recorded 10% in three rice growing seasons. Losses due to mechanical threshing and traditional sun drying were 3.16% and 3.14% respectively. Power tiller operated trolley showed the lowest carrying loss compared to shoulder and head carrying methods. Both kula and winnower were observed as the most appropriate method of grain cleaning. Mechanical intervention in threshing increased the losses, whereas decreased in transportation and winnowing. These data might be used for policy makers to assess the national food grain loss and for researchers to design and development new technology to reduce the postharvest loss. The study should be continued to other regions for consistent results.Bangladesh Rice j. 2016, 20(1): 23-32

Postharvest losses of tomato pose serious threat on the economic viability of actors in the tomato production chain in Nigeria. Therefore, postharvest losses of tomato among marketers in Ibadan Metropolis of Oyo State Nigeria were investigated by the researchers. One hundred and twenty tomato marketers were chosen from the five food markets in Ibadan metropolis through a simple random sampling technique. The study adopted linear regression and descriptive statistics to analyze data. The outcomes of the investigation show that females were 92.5% and 88.3% were married. Capital is primarily raised through cooperative societies (57.5%). Postharvest losses of tomato accounted for 18.9% of purchase which represents ₦124,800/day. The major causes of PHLs are poor packaging (100%) and poor storage (100%) by the tomato marketers. Meanwhile, all the respondents (100%) adopted sorting to reduce PHLs of tomato. The regression analysis showed that education has a significant effect to reduce PHLs of tomato. The study concluded that huge postharvest and monetary losses of tomato are experienced by the tomato marketers. The study recommends provision of quality postharvest handling education to tomato marketers as a way of reducing PHLs of tomato in Ibadan.

Tomato is a very well-known horticultural crop in Bangladesh. In order to make tomato production profitable postharvest management is very important. The present study assessed tomato postharvest losses in four intensive growing sites of Jamalpur and Rangpur districts of Bangladesh. Farm level postharvest losses were measured through using descriptive and inferential statistics. Cobb- Douglas type multiple linear regression model was used to identify the factors affecting farm level tomato postharvest loss in the survey areas. Farm level postharvest loss of tomato was 12.45% per farm in the survey area. From this3.59% was due to partial damages and the rest 8.86% was for full damages of tomato. The major causes for postharvest loss of tomato were rotten, disease and insect infestation. This loss incurs financial loss at farm level by BDT 152.45 per decimal of tomato cultivation. Total harvested amount, family member and selling price were some of the important factors for tomato postharvest loss in the survey area. Wide practices of improved postharvest management practices are essential to reduce tomato postharvest loss in the survey area.

Demand for citrus fruit has increased over the years in Nigeria. However, post-harvest loss of tropical fruits is high in developing nations owing to poor handling and storage facilities along the supply chain. The study therefore assessed levels and correlates of postharvest losses of fresh oranges along the orange supply chain. Primary data collected from marketers and producers of orange were analysed using descriptive statistics and ordered logit. Orange farming was dominated by male (68.4%) while orange marketing was dominated by females. Most of the producers (63.16%) and wholesalers (65.38%) experienced postharvest loss of 6-10%, while 46.79% of the retailers experience a postharvest loss of less than 5%. Being a male farmer that harvested oranges in the afternoon increased the likelihood of postharvest losses among the farmers while having a large household size reduced it. However, education, smallholding marketing and use of storage facilities reduced the likelihood of postharvest loss among orange marketers. Postharvest training for farmers and marketers on fruit harvesting and storage methods will help to minimise postharvest loss from producers to retailers.

The study assessed the volume and value of postharvest losses of cucumber in Rajshahi, Rangpur and Bandarban districts of Bangladesh. The survey covered 180 cucumber farmers. Multistage stratified random sampling technique was used to select the respondents. Postharvest loss was calculated by evaluating the quantitative and qualitative losses of cucumber. Among the respondents 71% were belonged to small farm size category followed by medium (21%) and marginal farm size category (6%). Average per hectare postharvest loss was 3929 kg in the survey areas. Postharvest loss was found highest in Rangpur (5781kg) followed by Rajshahi (4075kg) and Bandarban (1931kg). Total postharvest loss was 51.79% due to complete physical damage and the rest (48.21%) was due to partial physical damage. Sorting and grading stages accounted to 27.52% and 24.98% respectively were responsible for complete physical damage and partial physical damage. The least postharvest loss (3.61%) was due to storing of cucumber, whereas the highest loss (24.03%) was due to insect infestation. Besides, rotten and skinning causes for complete and partial physical damages of cucumber in Rajshahi district, where it was due to insect infestation in Bandarban and Rangpur district. The farmer of Rangpur district spent 81720 per hectare of cucumber cultivation, whereas it was Tk. 62354 and Tk. 34826 Rajshahi and Bandarban district respectively.

Full textAbstract:
In developing countries, food systems are mainly characterized by unorganized, traditional supply chains, and limited market infrastructure. Bulk quantity of the harvested produce is lost every year because of the absence of proper postharvest handling and management practices. The current study was conducted to estimate and identify the major causes for postharvest losses of fruits and vegetables in Debre Markos, north-western Ethiopia. Forty respondents who were retailing fruits and vegetables were randomly selected and qualitative and quantitative data were collected by using direct market observation and semistructured questioners. The result of the present study revealed significant differences between sociodemographic factors, handling practices, and postharvest loss. Educational status, selling experience, and packaging material have a significant relationship with postharvest loss. A significant difference was obtained among the transportation methods used, the selling place, storage methods, and materials. The result also indicated that fewer than 20 percent of respondents practiced selling fruits and vegetables in the resident mini shop. The majority of damaged produce was sold at a discount price. Retailers do not have formal knowledge of postharvest handling practices. The average postharvest losses of fruits and vegetables were estimated to be five to eighty-three percent of the market share. Mainly, during retailing, rotting, mechanical damage, poor handling, improper management of temperature and relative humidity, and hygiene problems during handling are among the major causes of postharvest losses. To reduce the high postharvest loss and supply quality products for consumers throughout the year, intervention activities such as the construction of permanent selling place for perishables, practicing various evaporative cooling technologies, outset training, awareness creation, and infrastructures should be effectively and urgently addressed.

This study aims to analyze the supply chain of potatoes and determine the factors affecting postharvest losses of potatoes at the producer level of Bangladesh. Data were collected through a face-to-face interview schedule from a sample of total 60- 30 farmers, 6 wholesalers, 5 aratdars, 5 retailers, and 14 consumers in Sirajdikhan and Sadar Upazila of Munshiganj district. Descriptive statistics (percentages, frequencies, etc.) and multiple linear regression analysis were used for this study. The result shows that channel 4 is the longest marketing chain in the study area which includes the marketing actors – farmers, aratdars, wholesalers, retailers, and consumers. In the supply chain of potatoes, the amount of postharvest loss is 6.6% for the producer’s level, 5.3% for the wholesale level, 1.10% for the aratdar level, and 2.1% for the retailer level in the study area. The regression model reveals that age and amount of production have a significant positive relationship, while experience has a significant negative relationship with the postharvest losses of potatoes. The study also shows that lack of storage facility (48.94%) and poor packaging system (32.73%) are the major reasons for occurring postharvest losses of potatoes. The farmers and intermediaries suggested that it is necessary to identify the maturity stage of potatoes at harvesting time (70%), improve the cold storage facility (56.67%), and improve the loading and unloading system (56.25%), etc. for reducing postharvest losses of potato.

ABSTRACT Although difficult to pin down an exact figure, the idea that postharvest losses (PHL) of perishables in Brazil stand at 30-45% has been widely accepted. In spite of the modernization of production systems and the logistics and distribution of perishables in the last decades, postharvest losses continue to be a persistent and relevant problem. However, little is known about what has already been published on the subject. This work addresses precisely this issue, based on a comprehensive survey of publications on PHL of fruits and vegetables. Bibliographic searches were performed at the Embrapa’s library system, Google Scholar and SciELO. Several publications on PHL of fruits and vegetables were reviewed and grouped according to their scope and objectives into three major categories: (1) PHL studies: estimates, measurements, research projects, reviews; (2) postharvest technologies: application of technologies, studies of postharvest physiology, diseases and/or mechanical damage; (3) economics: studies of economics, logistics and management. Results of this analysis are discussed in a historic perspective and mainly in what they reveal of the impact of social and technological development on the studies of PHL in horticultural crops.

Abstract Most people have experienced occasions when senescence in a horticultural commodity has disappointed them as consumers. This may have been when a dozen roses, ordered for someone special, failed to open and deliver the visual and fragrant pleasure that was expected. Perhaps it was when the bushel of apples stored in the cellar was found to be shrivelled and too soft to consume. Our personal experiences take on economic significance when one considers the cumulative effect of the losses that occur during the harvesting, handling, storage, and distribution of fresh fruits, vegetables, and flowers. Estimates have placed the losses during marketing at anywhere from 5% to 50%, depending on the commodity. Directly or indirectly, all of these losses are related to processes of senescence.

Irradiated cut Rosa × hybrida `Royalty' flowers were used to determine the efficacy of electron-beam irradiation for extending flower postharvest life by reducing native and inoculated populations of Botrytis cinerea. In preliminary experiments, roses received irradiation dosages of 0.00, 0.50,1.00, 2.00, and 4.00 kilogray (kGy), along with an untreated control, to establish killing dosages. Irradiation dosages of 1.00 kGy or greater irreversibly damaged rose petal tissue. In subsequent experiments, roses irradiated at dosages of 0.00, 0.25, 0.50, 0.75, and 1.00 kGy, and an untreated control, were used for evaluating postharvest events. We have found that irradiation dosages of 0.25 and 0.50 kGy slowed the rate of flower bud opening slightly and did not decrease postharvest quality or longevity. Inoculated and uninoculated roses irradiated at 0.00, 0.25, 0.50, and 0.75 kGy were used to determine if electron-beam irradiation could reduce Botrytis infection and proliferation during postharvest storage, and these results also will be presented.

Full textAbstract:
A semistructured questionnaire based on the commodity system assessment methodology (CSAM) was used to determine postharvest losses in vegetable amaranths (VA). Fifty producers and retailers were randomly selected from five and four major VA producing areas and markets, respectively, and interviewed. Data obtained were subjected to descriptive statistical analyses. The survey revealed that absence of laws, regulation, incentives, and inadequate technical information affected the production of VA. The utmost preproduction challenge was poor quality seeds with poor seed yield (35%), low viability (19%), and nontrueness (46%). It was noted that some cultural practices including planting pattern and density, irrigation, and fertiliser use had effects on postharvest losses. Some postharvest practices used were cleaning with water, trimming, sorting, and grading. Usually the produce was transported to marketing centers by cars and motor cycle trailers. Generally poor temperature management after harvest was a big challenge for the postharvest handling of VA. The potential of vegetable amaranths as a commodity in the study area can be enhanced by providing the necessary institutional support, incentives, and use of good management practices along the value chain. An interdisciplinary approach and quantification of losses along the chain are recommended for any future study.

Full textAbstract:
Sweet potato is now classified among the high-priority crops targeted at reducing food insecurity and malnutrition in many countries. Despite this growing interest, high postharvest losses caused by poor handling, physiological weight loss, sprouting, weevil (Cylas spp.) damage and microbial decay remain a challenge. Decay losses due to tip rot and other pathogenic fungi are a challenge in Ghana. Incidence of tip rot, which is characterized by a dry decay at either or both ends of roots, is severe due to late harvesting of roots which are intended for storage. This study evaluated a series of postharvest techniques which can be integrated to extend shelf-life in small scale storage. These include harvest maturity, root tip coppicing, hot water treatment, honey waxing and sanitizing in postharvest chemicals. Tip coppicing significantly (P<0.001) reduced the incidence of tip rot across the varieties when stored for 8 weeks, but dipping roots in different oils did not significantly (P<0.05) reduce tip rot incidence. Decay losses in the control and hot water treated roots were similar during the first 4 weeks after storage, but later losses were significantly severe in hot water treated roots. The range of fungi genera identified in this study are generally fungal endophytes; often symptomless in roots but become pathogenic when conditions are favourable. Due to the root thin skin, mechanical injuries during harvesting and handling become infection pathways for such pathogens. Therefore, integration of best practices at each step of harvesting and postharvest handling operations can significantly minimize decay losses.

Full textAbstract:
Fruit diseases brought on by fungus infestation leads to postharvest losses of fresh fruit. Approximately 30% of harvested fruits do not reach consumers’ plates due to postharvest losses. Fungal pathogens play a substantial part in those losses, as they cause the majority of fruit rots and consumer complaints. Understanding fungal pathogenic processes and control measures is crucial for developing disease prevention and treatment strategies. In this review, we covered the presented pathogen entry, environmental conditions for pathogenesis, fruit’s response to pathogen attack, molecular mechanisms by which fungi infect fruits in the postharvest phase, production of mycotoxin, virulence factors, fungal genes involved in pathogenesis, and recent strategies for protecting fruit from fungal attack. Then, in order to investigate new avenues for ensuring fruit production, existing fungal management strategies were then assessed based on their mechanisms for altering the infection process. The goal of this review is to bridge the knowledge gap between the mechanisms of fungal disease progression and numerous disease control strategies being developed for fruit farming.

Full textAbstract:
Postharvest technologies have allowed horticultural industries to meet the global demands of local and large-scale production and intercontinental distribution of fresh produce that have high nutritional and sensory quality. Harvested products are metabolically active, undergoing ripening and senescence processes that must be controlled to prolong postharvest quality. Inadequate management of these processes can result in major losses in nutritional and quality attributes, outbreaks of foodborne pathogens and financial loss for all players along the supply chain, from growers to consumers. Optimal postharvest treatments for fresh produce seek to slow down physiological processes of senescence and maturation, reduce/inhibit development of physiological disorders and minimize the risk of microbial growth and contamination. In addition to basic postharvest technologies of temperature management, an array of others have been developed including various physical (heat, irradiation and edible coatings), chemical (antimicrobials, antioxidants and anti-browning) and gaseous treatments. This article examines the current status on postharvest treatments of fresh produce and emerging technologies, such as plasma and ozone, that can be used to maintain quality, reduce losses and waste of fresh produce. It also highlights further research needed to increase our understanding of the dynamic response of fresh produce to various postharvest treatments.

There are several factors that generate postharvest losses of Citrus sinensis, but none have been focused on the central jungle of the Junín region of Peru. The objective of this research was to evaluate postharvest losses of Citrus sinensis in the province of Satipo, Junín region of Peru, considering the stages of the production chain. The methodology was applied to descriptive and cross-sectional design. A sample of 10 orange trees, 3 transport intermediaries and 5 traders selected for compliance with minimum volume and quality requirements were used. The °Brix, pH and acidity characteristics of the fruit were determined. Subsequently, absolute and percentage losses were quantified through direct observation, surveys and interviews. The main postharvest losses of Citrus sinensis were 1.50% in harvesting and detaching, 1.75% in transport to the collection center, 2.23% in storage and transport by intermediaries, and 2.90% in storage and sale by retailers. The overall loss was 8.12% throughout the production chain and US$5.75 per MT of C. sinensis harvested. The main damages found were mechanical and biological, caused by poor harvesting and packaging techniques, precarious storage and careless transport of the merchandise.

Orange wastage through postharvest losses has contributed to food scarcity, economic loss and massive importation of food items in Nigeria. The research was mainly carried out to investigate the determinants of orange postharvest losses among orange farmers in Konshisha Local Government of Benue State, North Central geopolitical zone of Nigeria. Primary data was collected from the orange farmers using structured questionnaires and key informant interviews. Descriptive statistics and Ordinal Regression model were used to analyse the data collected. The quantity lost was perceived at six (6) categories. The results revealed that most (63.7%) of the farmers were above 34 years of age. Also the majority (95.1%) were male, while 55.3% of the respondents’ farm size was relatively large with 200 and above stands of orange. The farmers’ literacy level was 73.6%. Those that belonged to farmers groups were 39.5. Further results established the use of probit link function in the ordinal regression modelling and that the significant factors affecting orange postharvest losses in the area are farmer’s lack of education and farmers not belonging to any association or group. The only significant covariate with the postharvest loss quantity of orange is farm size. The test of parallel lines established that, the location parameters (slope coefficients) are the same across response categories.

Full textAbstract:
Seasonality in mango production is a major factor contributing to high postharvest losses reported in the value chain. Oversupply during the high season is one of the factors that contribute to the high postharvest losses (≥ 50%) in the supply chain in Kenya. Effective strategies to address seasonality can contribute significantly to postharvest loss reduction. Efficacy of two flower induction chemicals, potassium nitrate (KNO3) and ethephon on reproductive growth parameters and yield components were evaluated on two mango varieties: ‘Apple’ and ‘Ngowe’. KNO3 was applied at two concentrations (2 and 4%), and ethephon (600 and 1000 ppm) then compared to control (water). They were applied to trees which failed to flower/set fruit in 2014 season. There effect was established from reproductive growth parameters: days to flowering, number of panicles per tree, fruit set per 20 panicles, fruit fall and hormonal effect. KNO3 (4%) and ethephon increased percentage flowering in both ‘Ngowe’ and ‘Apple’ and AEZs (Agro-Ecological Zones), significantly (p < 0.05) shortened time to flowering and increased fruit set. The findings show that KNO3 and ethephon can be used to induce flowering/fruiting in mango fruits. These technologies can therefore be applied to induce off-season mango production to address seasonality and reduce postharvest losses during the peak season.

Solar light has fundamental roles in vast chemical, biochemical, and physical process in biosphere and hence been declared as “source of life.” Solar light is further classified into a broad range of electromagnetic waves, and each region in the solar spectrum bears its unique actions in the universe or biosphere. Since centuries, solar light is believed as a potent source of killing pathogens causing postharvest losses on food products as well as human skin diseases. Citrus fruit crops are widely produced and consumed across the world, but due to their higher juicy contents, Penicillium italicum (blue mold) and Penicillium digitatum (green mold) make their entry to decay fruits and cause approximately 80% and 30% fruit losses, respectively. Agrochemicals or synthetic fungicides are highly efficient to control these postharvest fungal pathogens but have certain health concerns due to toxic environmental residues. Therefore, the scientific community is ever looking for some physical ways to eradicate such postharvest fungal pathogens and reduce the yield losses along with maintaining the public health concerns. This review article presents and discusses existing available information about the positive and negative impacts of different spectrums of solar light exposure on the postharvest storage of citrus fruits, especially to check citrus postharvest rotting caused by Penicillium italicum (blue mold) and Penicillium digitatum (green mold). Moreover, a special focus shall be paid to blue light (390–500 nm), which efficiently reduces the decay of fruits, while keeping the host tissues/cells healthy with no known cytotoxicity, killing the fungal pathogen probably by ferroptosis, but indepth knowledge is scanty. The study defines how to develop commercial applications of light in the postharvest citrus industry.

Full textAbstract:
Reducing postharvest losses (PHLs) in the South African citrus industry is fundamental in ensuring food, income, and nutrition security. However, there is limited knowledge on the extent of postharvest losses, their diversity, and the associated inhibiting factors. These factors compromise postharvest loss management strategies and how they can be scaled up across production zones in South Africa. The study adopted a pragmatic philosophy to assess the magnitude and diversity of PHLs for citrus crops and assess the determining factors. A standardized questionnaire was administered to 137 citrus producers from the Eastern Cape Province’s three production zones. Multistage sampling which combined purposive and stratified proportionate sampling was utilized to select the province, production zones, and farmers. The study employed the embedded research approach with a zero-inflated Poisson (ZIP) model. The countfit and Vuong tests were used in Stata 15 to ascertain and correct for overdispersion and inflated zeros while isolating the model which best fitted the data. The ZIP regression model indicated that social (e.g., marital status, education, age), economic (e.g., yield), institutional (e.g., markets, extension, credit), and cross-cutting (e.g., pruning, cultivar) factors determined the magnitude of PHL exposure. Targeted and tailored capacity building on good agricultural practices in citrus production might help to reduce postharvest losses through the extension pillar. The production of Nova and Navel citrus cultivars may be promoted when these cultivars are easily accessible and available to farmers while researching other traits to reduce PHL incidences. Investment programs to support the use of water-efficient drip irrigation systems need to be initiated to reduce the chances of incurring considerable postharvest losses. Likewise, pest and disease control in citrus production should be intensified and targeted. Subsidized support for the maintenance of citrus plantations should be provided by the government and other stakeholders, such as citrus production associations.

During storage of sugar beet, respiration and rots consume sucrose and produce invert sugar. Diseases that occur in the field can affect the magnitude of these losses. This research examines the storage of roots with rhizomania (caused by Beet necrotic yellow vein virus) and the effectiveness of rhizomania-resistant hybrids in reducing postharvest losses. Roots of susceptible hybrids from sites with rhizomania had respiration rates 30 days after harvest (DAH) that ranged from 0.68 to 2.79 mg of CO2 kg–1 h–1 higher than roots of the resistant hybrids. This difference ranged from 2.60 to 13.88 mg of CO2 kg–1 h–1 120 DAH. Roots of resistant hybrids from sites with rhizomania had 18 kg more sucrose per ton than roots from susceptible hybrids 30 DAH, with this difference increasing to 55 kg Mg–1 120 DAH. The invert sugar concentration of susceptible hybrids from sites with rhizomania ranged from 8.38 to 287 g per 100 g of sucrose higher than that for resistant hybrids 120 DAH. In contrast, differences between susceptible and resistant hybrids in respiration rate, sucrose loss, and invert sugar concentration in the absence of rhizomania were relatively small. Storage losses due to rhizomania can be minimized by planting resistant hybrids and processing roots from fields with rhizomania soon after harvest.

Full textAbstract:
Present dietary recommendations for fruits and vegetables should be based on the bioavailability of essential nutrients at the time of optimum harvest. Few people, however, are fortunate enough to have available freshly harvested produce all year. With the development of improved postharvest technology, shelf life has increased dramatically in many parts of the world. How does the nutritional quality of fruits and vegetables change with increasing storage time, changes in storage atmosphere, different postharvest processes? Do these changes have an impact on dietary recommendations? Apples are capable of being stored for up to 12 months with properly managed temperature and storage atmosphere. Because information regarding this subject is lacking for apple (and many other fruits and vegetables), perhaps a model can be developed based on work with other commodities to help us understand the nutritional changes associated with different postharvest treatments.

Full textAbstract:
The study was conducted for assessing postharvest loss of major fruits in different hill regions of Bangladesh. The study areas covered four hill districts, namely Rangamati, Khagrachari, Bandarban and Moulvibazar and six selected fruits, namely mango, jackfruit, litchi, banana, pineapple and orange. These fruits are grown intensively in hill regions compared to other parts of Bangladesh. Data were collected from 2050 fruit growers and 749 traders of eight (8) upazilas considering accessible and less accessible areas. At farmers and traders level, the total postharvest loss of banana, pineapple, orange, mango, litchi and jackfruit were 372, 274, 200, 243, 165 and 380 kg/mt which was accounted about 37%, 27%, 20%, 24%, 17% and 38% of total production respectively. The main postharvest losses at farm level were incurred due to severe attack of insect, bat, squirrel and monkey. For traders, major losses were incurred during transportation. On the basis of retail price, the annual economic loss was estimated as Tk. 2107.5 crore and the maximum loss was incurred for banana (Tk. 705.79 crore) followed by pineapple (Tk. 550.58 crore) and mango (Tk. 508.95 crore) and the lowest for orange (Tk. 1.12 crore). It is interesting to note that, transportation dummy, labour dummy and market demand dummy had negative and significant effect on the postharvest losses. If transportation facilities can be improved and market demand and labour availability can be increased, postharvest loss will be decreased to an acceptable level at the study areas.Bangladesh J.
