The study was conducted to assess the factors that contribute to post harvest losses of farm produces in the Nkwanta Districts, Volta Region, Ghana. Data was collected from 250 farmers in the district using a structured questionnaire. The last item on the questionnaire examined the level of agreement attached to various factors influencing post harvest losses in the district on a five point Likert scale. Multivariate factor analysis method was used in the analysis. The results indicated that about 87.2% of the total respondent experience of post harvest losses and there are five salient factors that influence post harvest losses. Difficulties in market accessibility related factors was the most important factor of all. Another important factors accountable for post harvest losses are lack of knowledge and technology related factors, lack of storage facilities and poor packaging, the poor road network, and labour cost. It is therefore recommended that different forms of training and information should be made available for farmers. Also, the establishment of the factories and storage facilities at farming communities should be put in place in order to reduce post harvest losses by way of processing and storage of the excess produces at the local level.

Abstract Pigeonpea (Cajanus cajan Milsp) is an important food crop in the dryland tropics. The objective of this research was to evaluate the effects of post-harvest processing and storage on sensory characteristics of pigeonpea. Moisture content of harvested pigeonpeas was assessed at 0. 22 and 60 days of storage. Five treatments of podded, deep-frozen (-18°C), blanched (72°C, 2min), oven-dried (65°C, 8hr), and blanched + oven-dried pigeonpea, in a completely randomized design were evaluated for sensory characteristics at post-harvest storage. The reduction in moisture content was highest (43%) in podded and lowest (6%) on blanched pigeonpea at 60 days of storage. Consumer acceptance of pigeonpea varied significantly (P < 0.05) for traits of physical appearance, color, aroma, and seed tenderness. Physical appearance of podded pigeonpea had a sensory rating of 6.3, indicating high acceptability, while blanched samples had a 6.0 rating on a 7-point hedonic scale. The podded, blanched + oven-dried and seed tenderness had 5.6, 6.6, and 6.1 scores, respectively. The sensory scores of podded and oven-dried were attributed to high sugar concentrations (4.25 mg/100g) the samples at 22 days post pre-treatment. Palatability and overall acceptance of pigeonpea were comparable, indicating that post-harvest treatment and 22-day storage had positive sensory attributes. Post-harvest processing treatment and storage may enhance vegetable pigeonpea utilization in the dryland regions.

Ochratoxin A (OTA) is a mycotoxin that contaminates several foodstuffs, including cocoa. It has nephrotoxic, teratogenic and carcinogenic properties in humans. The effect of post-harvest processing and storage on the OTA contamination of cocoa was studied over three successive cocoa seasons (2005, 2006 and 2007) in Cameroon. The type of fermentation (box or heap) did not significantly influence bean OTA content, which varied from undetectable (<0.03 ng/g) to 0.25 ng/g, remaining below 2 ng/g (the defined standard for cocoa beans). However, pod damage and late pod opening were aggravating factors for OTA contamination of cocoa. If pods were not intact (intentionally or naturally damaged), OTA was found in samples with contents of up to 75.5 ng/g before processing and 32.2 ng/g after 4 months' storage. This contamination exceeded the levels tolerated for export. In addition, some of the cocoa produced is processed locally and consumed as chocolate, cocoa powder, chocolate filled sweets, cocoa-based drinks and cocoa butter. In Cameroon, the average daily consumption of cocoa by-products is estimated at 0.75 g/d for adults and 1 g/d for children. Consequently, for maximum OTA contamination of cocoa beans, the maximum daily exposure to OTA would be 1.61 ng/kg bw/d in young children weighing around 20 kg, greatly contributing to the exposure of young consumers.

Outputs of all agricultural commodities produced in the field have to undergo a series of operations such as threshing, transportation, processing and storage and exchange before they reach the consumer and there are appreciable losses of outputs during these stages of their handling. This is most uncertain to get expected returns. Moreover, vegetables are more perishable then food grains. Hence, post-harvest losses are quite often, at different marketing levels than food grains. The presence study was undertaken to find out the post-harvest losses of selected vegetable in Akola district for the year 2017-18. The data of 90 tomato growers were purposely collected from randomly located villages of the district. Simple tabular analysis was carried out to accomplished the objectives. This study revealed that per hectare cost of cultivation of tomato was Rs.101804.29 whereas per hectare the net return was Rs.73253.37 The input output ratio at Cost C2 in production of tomato is 1.72. The per hectare post-harvest losses at the farm level was estimated to be 16.49 quintal in tomato. The corresponding economic loss was 16645.20 Rs./ha. It is suggested that to prevent from the losses the farmers should be aware through training on standardization and grading, handling, proper packing and providing storage facilities and quick transportation to prevent the economic losses.

The increases in consumer awareness of the potential health benefits of green tea have driven global demand for green tea products. This study investigated the effect of post-harvest processing and storage of Japanese-styled green tea (Camellia sinensis var. sinensis) grown in NSW, Australia. Harvested material underwent a processing delay of 6, 12, 18 or 24 h at temperatures of 0, 5 and 25 °C. Targeted green tea constituents: theanine, caffeine and catechins were determined using HPLC with UV detection. Product quality and commercial value were determined using the Quality Index (QI) Tool. Reductions in constituent levels were evident within all storage delays, with nominal quality preservation achieved by reducing the temperature. The green tea material stored at 25 °C for 24 h created the most commercially valued product, despite it having visual characteristics more akin to a semi-fermented tea. These visual characteristics are traditionally considered markers of green tea damage and are discarded; however, QI-Tool scoring suggests that this raw material presents as a commercially favourable source of food loss and waste (FLW). The findings of this study extend our understanding of post-harvest processing delays and storage on green tea quality and suggest the viability of a commercially valuable semi-fermented produced from FLW.
