Résumé

A study was conducted to assess the potential of chitosan coating in extending postharvest life and maintaining quality of longan fruit during storage at low temperature. The fruits were treated with solutions of 0.5, 1 and 2% chitosan, respectively, and then stored at 2 °C and 90% relative humidity. Changes in respiration rate, polyphenol oxidase (PPO) activity, colour, eating quality, weight loss, total soluble solids, titratable acidity and ascorbic acid were measured. From the results, it is suggested that the application of chitosan coating could be beneficial in extending postharvest life and maintaining quality and, to some extent, controlling decay of longan fruit.
