Abstract: An experiment was done to increase the storage life of guava by modified atmosphere packaging. In this study fruits were packed in polypropylene bags with 2 pores, 4 pores, 6 pores, 8 pores and10 pores and observed the chilling injury and storage life of guava cv. Allahabad safeda stored at 6 ± 10 C. This experiment was conducted at Fruit Research Station, Sangareddy, Medak District, Telangana. The experiment was done by using completely randomized design with factorial concept with three replications per treatment. Guava fruits cv. Allahabad safeda were packed in polypropylene bags with different ventilation (2, 4, 6, 8 and 10 pores) and stored at6 ± 1º C. Fruits packed in polypropylene bags with 4 pores significantly recorded lowest PLW. Significantly highest fruit firmness and organoleptic evaluation were recorded in fruits packed in polypropylene bags with 4 pores. Significantly lowest chilling injury and electrolyte leakage was recorded in fruits packed in polypropylene bags with 4 poresand corresponding increase the shelf life of upto 25.63 days. The fruits kept under control recorded a shelf life of 20.05 days only. Titratable acidity was significantly lowest in fruits packed in polypropylene bags with 4 pores. Fruits packed in polypropylene bags with 4 pores recorded significantly highest TSS, brix-acid ratio and ascorbic acid.
