Tomato (Lycopersicon esculentum) is one of the most widely consumed fresh fruity vegetables in the world. Tomatoes were coated with 0.25 and 0.5 chitosan. The physico-chemical parameters and microbial load were studied for a period of 30 days. The lower concentrations of chitosan 0.25 was found effective than 0.5 in maintaining the physico-chemical characteristics. The results clearly indicated that fruits treated with chitosan were better in maintaining all physicochemical characteristics (pH-4.7 TSS-16.03 Acidity-0.35 Ascorbic acid-23.54 Weight loss-7.34 and Moisture-93.96) and better reduction in microbial growth (Total plate count-18.16 yeast and mold-5.12 cfu/log) sensory attributes (Appearance-4.43 Taste-4.06 and Flavour-4.43) than control throughout the storage period. The study concludes that chitosan coating could be a good alternative to preserve the quality and extend the postharvest life of tomatoes.

Abstract

Tomato (Lycopersicon esculentum) is one of the most widely consumed fresh fruity vegetables in the world. Tomatoes were coated with 0.25 and 0.5 chitosan. The physico-chemical parameters and microbial load were studied for a period of 30 days. The lower concentrations of chitosan 0.25 was found effective than 0.5 in maintaining the physico-chemical characteristics. The results clearly indicated that fruits treated with chitosan were better in maintaining all physicochemical characteristics (pH-4.7 TSS-16.03 Acidity-0.35 Ascorbic acid-23.54 Weight loss-7.34 and Moisture-93.96) and better reduction in microbial growth (Total plate count-18.16 yeast and mold-5.12 cfu/log) sensory attributes (Appearance-4.43 Taste-4.06 and Flavour-4.43) than control throughout the storage period. The study concludes that chitosan coating could be a good alternative to preserve the quality and extend the postharvest life of tomatoes.
