Mango fruit plays an important economic role in Côte d’Ivoire as the third major exported fruit after banana and pineapple. The main issue of the mango value chain in Côte d’Ivoire is linked to poor agricultural practices and postharvest losses due to climateric characteristics of the fruit. The aim of this study was to investigate the efficiency of bioactive edible coating made of garlic extract and cassava starch as a novel approach to enhance the postharvest quality and shelf-life of Keitt mango fruit.

This study was conducted to investigate the potential of phytochemical extracts on extending the shelf-life of harvested tomato fruits, and to determine which phytochemical extracts can best enhance its shelf-life. The free radical scavenging activity (FRSA) of tomato fruits coated with phytochemical extracts stored under ambient condition and the toxicity of the phytochemical coatings was also evaluated.

The purpose of this study was to evaluate the effect of chitosan concentration on the quality and shelf life of tofu. Tofu is treated by soaking in a chitosan solution with a concentration of 0.75 - 1.5%. The results showed that chitosan concentration 1% give the most stable pH value during storage, pH value ranged from 5.9 to 6.28, chitosan concentration of 0.75%, 1% and 1.25 % for the least reduced protein value.

The results of the study indicate that the less stable criteria on each sample background are the basis for selecting evaluation criteria for subsequent studies that contribute to reducing the cost of monitoring. The difference in the time it takes to estimate the stability of the product when using different methods also helps manufacturers consider the appropriate evaluation method for their products.
