This study determined the efficacy of modified atmospheric packaging (MAP) in enhancing the quality and shelf-life of tomato 'Samjhana' under ambient conditions during winter (March 2015: 15.5±4.5°C; 82±17% RH). MAP treatments were 25 micron-thick low-density polyethylene (LDPE), 50 micron-thick LDPE, 25 micron-thick polypropylene (PP), 50 micron-thick PP, and commercial clingwrap film. Samples held under ambient conditions in the open served as the control. Ten kg breaker fruits were used for each treatment per replicate; four replicates were used. Fruit were held in the MAP for 5 and 10 days to simulate short- and long-term holding and transport, respectively. After treatment, the samples were kept in the open. MAP was very effective in prolonging the shelf life of tomato. Fruit in 25-50 micron-thick LDPE showed better color retention and firmness, lower weight loss, and longer shelf life than the other treatments. The 5-day holding period in the MAP resulted in better quality and longer shelf life than the 10-day holding period. The results indicate that tomatoes can be successfully stored in MAP to minimize perishability and reduce postharvest losses.
