Abstract
The research was designed to extend shelf life of stored strawberry by bioactive chitosan coating. Strawberry fruits were dipped for 2 min in different concentration of irradiated chitosan (300, 500, 1000 and 1500 ppm) solution which were subjected to different gamma radiation doses (30, 40, 50 and 60 kGy) while uncoated fruits were served as control. Samples were packed in zip bags and stored in 4°C and kept for observation. Fruits treated with 50 kGy irradiated chitosan at 1500 ppm concentration showed significant delays in the change of weight loss, decay percentage, pH, and ascorbic acid content as compared with the uncoated control fruits. Samples stored in 4°C and packed in zip bags showed an increased shelf life up to…
