Abstract

Tomato is rich sources of minerals, vitamins, polyphenols, and carotenoids that are beneficial for human health. Chitosan and vanillin could be an elicitor to induced defense enzyme activities in host against pathogen causing disease. This study aimed to evaluate the effect of chitosan and vanillin coating on defense-related enzymes (PAL, PPO and POD) activites on tomato fruits during ambient storage Chitosan and vanillin in aqueous solutions i.e. 0.5% chitosan + 10 mM vanillin, 1% chitosan + 10 mM vanillin, 1.5% chitosan + 10 mM vanillin, 0.5% chitosan + 15 mM vanillin 1% chitosan + 15 mM vanillin and 1.5% chitosan + 15 mM vanillin, respectively, were used as edible coating on tomato fruits. The results revealed 1.5% chitosan + 15 mM vanillin have significantly lower the activities of defense enzyme i.e. peroxidase (POD) and polyphenoloxidase (PPO), and phenylalanine ammonia-lyase (PAL) while shelf life was prolonged to 25 days at 26 ± 2ºC and 60 ± 5% relative humidity without any negative effects on fruit postharvest quality
