Abstract: The present study aimed at the evaluation of postharvest quality of guava fruit (cv. Gola) stored under different packaging materials at room temperature. Transition in multiple quality parameters was quantified at fixed intervals (4-days) during the storage period of 20 days. Each packaging material had significant effect upon fruit quality as compared to control samples. The values of firmness, ascorbic acid and total phenolics inclined to retain in the packaged fruit samples as compared to control. Respiratory gases (ethylene and CO2) were hindered under HDPE and BDP packaging's materials. In terms of enzyme dynamics, catalase (CAT) was high with the passage of storage; however, lower activity of poly phenol oxidase (PPO) was observed in packed samples as compared to unpacked one. Biodegradable, PP and HDPE packaging showed promising results to maintain better fruit quality and revealed higher values for phenolics and vitamin C contents during storage.
