Modified atmosphere packaging of 'Kolikuttu' bananas at low temperature

Mature 'Kolikuttu' bananas were packed under modified atmosphere (M.A.) conditions using low density polyethylene (LDPE) bags and stored at 14 degrees C and 94% r.h. The effect of ethylene scavengers on storage life of banana was examined. The in-package concentrations of oxygen, carbon dioxide and ethylene were measured during storage. Percentage weight loss, changes in firmness, total soluble solids (TSS), pll and sugar: acid during storage were also determined. Based on the in-package gaseous composition, the optimum storage period was defined. After termination of storage, bananas were allowed to ripen naturally, and the physico-chemical properties of ripened banana were analysed. 'Kolikuttu' bananas could be packed in LDPE (0.075 mm) and stored at 14 degrees C and 94% r.h. for 24 d. Storage life could be further extended up to 30 d by using ethylene scavengers. Physico-chemical properties of M.A. stored banana after ripening were similar to those held under ambient conditions. Therefore, packaging of 'Kolikuttu' banana as individual hands in LDPE (0.075 mm) bags of 1:1 surface to weight ratio (cm(2) g(-1)) with 50 ml of saturated potassium permanganate absorbed onto suitable porous matrices could be recommended to increase storage life at 14 degrees C.
