Abstract

Changes in quality characteristics of tomato (Lycopersicum esculentum Mill) as influenced by modified atmosphere packaging (MAP) and γ-irradiation 0, 1, 2, 3 and 4 KGy doses and low temperature (LT, 12±1°C) storage at 90-95% RH were studied. Tomatoes packed with LDPE film could be stored up to 21 days at 12±1°C and 90-95% RH with the maximum retention of fruit quality characteristics such as 1.92 a/b ratio, 46.6 N shear value and 16.4 N penetration value as compared to 1.88 a/b ratio, 41.3 N shear value and 13.1 N penetration value in untreated open kept control tomatoes stored for 7 days under same conditions. Irradiation in combination with MAP and LT storage were not suitable for tomatoes harvested at breaker stage of maturity for shelf-life extension and maintenance of fruit quality.
