: Sweet corn ( Zea mays L.) is a grain harvested before maturity and consumed as a vegetable. An optimal supply chain, to preserve sugars and antioxidant (AO) capacity is essential to maintain quality of sweet corn. The choice of packaging film plays an essential role, especially in products with a high respiration rate such as sweet corn. Sweet corn grown on a commercial farm in Senegal was sampled at the harvest day, at the UK arrival date following 12–14 d of shipping (packaging date), at the best before date (BBD) and 5 days after the best before date. The results showed that high quality preservation of sweet corn is possible along a complex supply chain from harvest in Senegal through transport to the UK. Results suggested that lower perforation films have a beneficial role in preserving antioxidant capacity. Furthermore, damaged kernels in the cut-ends of the cobs were shown to be the main factor reducing the overall quality of the product.

The objective was to analyse the effect of the following factors: drying, hybrid and crop management on physical properties of two orange-flint maize respect to a dent hybrids, dried naturally and to 70 and 90°C, which were grown in a location of Argentina's main maize-production area during one growing season and with two levels of fertilisation respect to a control treatment. The drying only affected the arithmetic and geometric mean diameters. The length, width, and length/width, length/thickness, length/geometric mean diameter ratios, diameter of the spherical part of the kernel, sphericity and kernel volume depended on the hybrid. The bulk and kernel densities, porosity, thousand kernel weight, and angle of repose were influenced by the interactions drying*hybrid, drying*crop management, and hybrid*crop management. Thus, the flint maize hybrids should be dried to temperatures that not affected their physical properties, since these will determine their behaviour in storage plants.

This study investigates the perception, the importance and adoption determinants of pre and post-harvest technologies (PPHTs) along fresh tomato fruit value chain. Data was collected from value chain actors via a survey. The analytical result reveals the choice of cultivar type, and temperature management as the most important technologies being used to reduce post-harvest losses in Ghana's tomato value chain. There is a positive perception of PPHTs' ability to reduce post-harvest losses. However, the degree of perception differs among adopters and non-adopters of PPHTs. Whereas, increase in adopters' age and the perceived PPHTs risk are likely to undermine the adoption of PPHTs, increase in temperature and access to PPHT, education, labour, credits are likely to increase the adoption PPHTs significantly. Hence, there is the need to consider the perception, the importance of PPHTs, and the adoption determinants surrounding PPHTs in making policies to control post-harvest losses in tomato value chain.

This study considered post-harvest deterioration of green billeted and green whole stalk on sugarcane. A yield deterioration assessment was conducted in the Northeast of Thailand. To have an appropriate assessment, several sugarcane quality parameters such as sugarcane weight (kg), Brix %, juice purity %, commercial cane sugar (CCS) % of cane, reducing sugar % Brix, mannitol, lactic acid, and dextran in mg/kg Brix unit were used to investigate post harvest sugarcane deterioration due to bacterial activity. The deterioration trial was undertaken over 13 days to investigate the green billets (GB) and green whole-stalks (GWS). All sugarcane quality parameters, CCS %, reducing sugar % Brix and juice purity % showed a faster deterioration rate of GB than GWS under identical time and climatic conditions. Mannitol, lactic acid and dextran were useful as an indicator of deterioration and estimating the juice purity drop during post-harvest sugarcane deterioration.

Pre-harvest practices (PHPs) are key to sustainable mango farming, including their impact on fruit quality at harvest and post-harvest longevity. However, the adoption of these practices is still below the expected levels for optimal production. This paper analyses the determinants of the extent of adoption of PHPs using cross-sectional data collected in Embu and Machakos counties of Kenya. Multivariate probit and ordered probit models were applied. The results reveal that there are significant correlations among the PHPs. Further analysis shows that the probability of and the level of adoption of PHPs is influenced by region, years of experience in mango farming, off-farm income, mango sales, number of mango trees, access to inputs, and perceptions towards PHPs. These results indicate that policymakers and their development counterparts ought to strengthen farmers' access to farm inputs and extension services, and address barriers to financial access to accelerate the adoption of PHPs.

The physicochemical changes in fruits can be influenced by postharvest handling during the storage period. The physicochemical properties (firmness, soluble solids content, pH, moisture content, and colour) were analysed over seven interval days to observe the changes between the seeded and seedless watermelons. The results indicated a decrease in the firmness, soluble solids content, and moisture content values, whereas the pH values increased for both seeded and seedless watermelons. The L*, b*, and chroma values increased whereas the a* value reduced. The hue angle value increased for both seeded and seedless watermelons. Principal component analysis (PCA) was used to determine the quality changes of both varieties and correlations among the physicochemical properties of watermelon samples. The findings indicated that PCA has the potential to characterise quality changes patterns in the seeded and seedless watermelons during storage and could establish the basis of major impact on the determination of fruit quality.
