Studies have revealed that edible coatings particularly Carnuba wax and chitosan can be used as postharvest treatment for enhancing the storability of bitter gourd gourd fruits under ambient storage conditions (temperature 27.4-32.3°C and 70-81% RH).There were seven treatments, replicated thrice and experiment was laid out in completely randomized design. The bitter gourd fruits coated with 1.0% Carnuba wax maintained higher sensory score of 6.67 in storage. The physiological loss in weight was documented minimum in Carnuba wax treated fruits with a weight loss of 4.61% by the end of storage period. The fruits treated with Carnuba wax (0.50 and 1.0%) recorded no spoilage respectively up to 4 days. Higher disease reduction index of 83.98 was observed. The chlorophyll content remained high on 2nd day, 4th day as well as on 6th day in storage with maximum retention of chlorophyll a (9.67mg/g), chlorophyll b (4.60 mg/g) and total chlorophyll (14.28 mg/g) in 1.0%Carnuba wax coated fruits. Hence, it could be concluded that postharvest application of 1.0% Carnuba wax has a potential to extend storage life and preserve other quality attributes.
