Effect of gamma irradiation on physico-chemical properties and shelf life of tomato (Solanum lycopersicum cv. Anand tomato-3)
Author(s): DB Desai and DC Joshi
Abstract: The present investigation was conducted with a broad aim of increasing the shelf life of tomatoes using gamma irradiation as a pre-treatment. Tomatoes (Anand Tomato-3) at two different maturity stages i.e. breaker and light-red stage were exposed to different levels of gamma irradiation (1.00, 2.00, 3.00 and 4.00 kGy) and stored at two different storage temperatures i.e. 28±1â°C and 14±1â°C. All the pretreated tomatoes were evaluated for its physico-chemical properties and shelf life. For breaker stage tomatoes, increasing dose level of gamma irradiation showed superior physico-chemical properties and increased shelf life than the control. Breaker stage tomatoes treated with 4 kGy dose and stored at 14±1â°C showed highest i.e. 150 % increase in shelf life as compared to control tomatoes. Results for light-red stage tomatoes were antithetical than breaker stage tomatoes. Gamma irradiation of light-red stage tomatoes showed inferior physico-chemical properties and decreased shelf life than the control during storage.
