Abstract

Custard apple, a tropical fruit, is underutilized because of its poor storability. Researchers have worked on various aspects for improving the storage life of fruits; still its storage life is limited to few days. So to counteract this, an experiment was conducted to study the effect of modified atmosphere packaging using three different kinds of films along with low temperature storage at 8, 12 and 15 °C and observations were recorded at weekly interval. The study indicated an increasing trend in the respiration rate and ethylene production rate as well, and the rate increased with increase in storage temperature and duration. The physiological loss in weight in packed fruits showed a drastic reduction. Titratable acidity increased as storage duration while ascorbic acid shown exact reverse trend. There was significant increase in reducing sugar and total sugar as duration increased but rate was low in 8° C fruits.

Keywords
