ABSTRACT
The present experiment was carried out during 2016-2017. The effect of different gamma irradiation dosages on shelf-life and quality of papaya cv. Taiwan was investigated at ambient temperature during storage. The physical and quality characteristics such as Physiological loss in weight, spoilage, shelf life, ß-carotene, TSS, reducing sugar and total sugars along with organoleptic evaluation were studied at an interval of 3 days upto 12th days after storage. The data were statistically analyzed using completely randomized design. Irradiation of papaya fruits with 0.8kGy dosage and stored at ambient temperature gives high shelf-life days and increased upto 12 days when compared to control (5 days) and also shows highest score for organoleptic evaluation. At the end of storage studies T4 - 0.8kGy treated fruits have shown the best results for TSS, PLW(%), sugars and carotene content.
