The present study was undertaken to evaluate the influence of laboratory made ethylene absorbents particularly Silica gel-permanganate and Celite-permanganate mixture on postharvest quality of bitter gourd cv. Meghna-2 under ambient storage conditions (temperature 27.2-31.4°C and 69-72% RH) packed in 50µ polypropylene bags (20cm x 17cm size). The experiment was laid out in completely randomized design with seven treatments and replicated thrice. The fruits stored with Celite-KMnO4 mixture maintained higher sensory score of 6.00 in storage. The physiological loss in weight of fruits with Celite-KMnO4 mixture documented minimum weight loss of 2.04% at the end of storage. The fruits treated with Celite+KMnO4 (8 g/kg) recorded no spoilage (0.00 %) respectively up to 4 days in storage followed by gradual rise.Celite+KMnO4 8g/kg showed higher disease reduction index (100.00 respectively) up to 4 days of storage period. The chlorophyll content remained high till expiry of storage period with maximum retention of chlorophyll a (9.00 mg/g), chlorophyll b (4.29 mg/g) and total chlorophyll (13.29 mg/g) in Celite+KMnO4 (8 g/kg) mixture respectively. Hence, it was concluded that bitter gourd fruits packed with polypropylene films along with Celite-permanganate mixture can successfully preserve the major postharvest attributes stored at ambient conditions.
