Abstract
The present investigation was conducted to evaluate the effect of different packaging films on storage life of tomatoes in consumer packages. Five packaging films HDPE (25μ), LDPE (25μ), PP (25μ), shrink (15μ) and cling (15μ) were used to wrap the consumer packages made of corrugated trays. These film wrapped consumer packages were evaluated for postharvest quality of tomato cv. Punjab Varkha Bahar 4 under ambient and cold storage conditions. The physico-chemical parameters measured to determine the storage life of tomato were PLW, spoilage, firmness, colour, gas concentration, TSS, titratable acidity, total phenols, ascorbic acid and lycopene content at 0, 3, 6, 9, 12 and 15 days of storage under ambient storage conditions (17.4-19 °C, 25-28% RH) and at 0, 7, 14, 21, 28 and 35 days of storage under cold storage conditions (10±1°C and 90-95% RH). Cold storage of tomato was found to be better than ambient storage. Tomato packed in cling film wrapped consumer packages were found to be best for 9 days of storage life with desirable physical and chemical attributes as compared to control packages which maintained the storage life up to 3 days only under ambient storage conditions. Tomatoes packed in cling film wrapped consumer packages proved to be the best for 21 days of storage life with minimum weight loss and spoilage, desirable fruit firmness, better colour and other quality parameters as compared to control packages which maintained the storage life up to 7 days only under cold storage conditions.
