Guava fruit is a climacteric fruit and its production is throughout the world. Pakistan also include in the list of Major producing country of Guava fruits. This research was carried out in two phases of the set of experiments. In the Frist experiment, the basic physico-chemical characterization of Guava verity (Gola) and in the second part of experiments, checked the storage stability assessment of guava in response to different dose of irradiation like 200Gy, 600Gy, 1KGy, 1.4KGy and 1.8KGy. The fruits exposed to the irradiation dose (1.0 kGy) had significantly highest TA (%) values as compared to other doses. Thus, in this study, the soluble solids contents practically remained, and there was a significant reduction in acidity at the end of the storage period, which provided an increase in the ratio, a behavior that is natural during fruit ripening. We can conclude that gamma irradiation can be successfully applied as better postharvest intervention to retain the storage related quality attributes of guava fruit and to enhance its shelf life so that it can be exported to distance markets for the generation of revenue. It is also proved that gamma irradiation significantly retained the nutraceutical potential of guava fruits during storage period up to 24th days.
