Rot and damage caused by post-harvest phytopathogenic fungi affect fruit quality. Essential oils (EO) are considered as an alternative to fungicides. Postharvest diseases of fruits may also be controlled by the bagging approach and the use of antimicrobial packaging. Based on the beneficial properties of EO and the concepts of bagging and antimicrobial packaging, this study aimed to develop sachets containing EO to be used as part of an antimicrobial packaging system. The activities of oregano, cinnamon and lemon grass EO were evaluated testing the sachets in vitro against the phytopathogenic fungi Alternaria alternata, Fusarium semitectum, Lasiodiplodia theobromae and Rhizopus stolonifer. The effects of the sachets on the microbiological and physicochemical parameters of post-harvest papaya were also evaluated. Both pure and sachet-incorporated EO showed antifungal activity in vitro against all tested fungi. For papaya, sachets containing cinnamon, oregano and lemon grass showed a significant reduction in the growth of mesophilic aerobic bacteria, yeasts and mould, with the cinnamon sachet causing the greatest reduction in microorganisms at the end of the storage time. Physicochemical parameters of papaya, such as weight loss, colour, firmness, total soluble solids/titratable acidity ratio and pH were not significantly altered by the presence of EO sachets, thus not affecting the natural ripening process of the papaya.

Genetic modification has led to fierce debates around the world. Nevertheless, scientific evidence for its potential effects on the structure and performance of industries has hitherto remained rather meagre. In this article, we take some preliminary steps towards closing this gap by exploring the effects of the introduction of a genetically modified cassava variety on the structure and efficiency of the starch industry in Thailand. Currently, producers of cassava starch are confronted with a problem called post-harvest deterioration, which reduces the quantity and quality of starch in cassava roots within 24 to 48 hours after harvesting, leading to lower payments for farmers and lower starch recovery rates for factories. In addition, post-harvest deterioration prohibits factory owners to hold large stocks of fresh cassava. Combined with a strong seasonal fluctuation of supply, this leads to a low utilisation of installed processing capacities at the starch factories. In this article, we examine how the structure and performance of the Thai starch industry would change in case a genetically modified cassava variety would be introduced that no longer suffers from post-harvest deterioration. After having interviewed 19 stakeholders in this industry, we developed two simple linear programming models to examine the optimal locations, capacity classes and utilisation percentages for starch processing plants in the Northeast of Thailand. Our findings demonstrate that an extension of the storability of cassava to 45 days will not only diminish the number of factories needed, but it will also cause most large-sized factories to be replaced with medium-sized plants. Moreover, introducing a new cassava variety with such properties is estimated to render benefits of approximately US $ 35 million for Thai cassava farmers and factory owners.

ABSTRACT The objective of the present work was to evaluate the use of extracts of leaves and fruits of neem (Azadirachta indica Juss) as coating for papaya Formosa fruits aiming to maintain their quality during post-harvest storage. A completely randomized experimental design in a 5x5 factorial arrangement was used, with 3 replications of 2 papaya fruits per plot. The treatments consisted of five coatings with extracts of neem leaves and fruits (leaf extracts at 5 and 10%, fruit extracts at 5 and 10% and a control treatment without coating) and five storage periods (0, 3, 6, 9 and 12 days) under mean temperature of 30.4 °C and relative humidity of 42%. The fruit weight loss, external appearance, pulp firmness, titratable acidity and soluble solids were evaluated, and the fungi species on the fruit surface of each storage were identified and quantified. The treatments with extract of neem leaves and fruits at 5% had papaya fruits with best external quality and provided best control of growth of phytopathogenic fungi. Regarding external appearance, papaya fruits coated with extracts of neem leaves and fruits at 5% had a shelf life of 12 days, while those coated with extracts at 10% had a shelf life of 9 days.
