Abstract :
Shelf life extension is the holy grail for the fruit and vegetable industry. Extension of shelf life of fruits and vegetables has several advantages, it improves the quality, taste and texture of the food, it reduces food waste. The aim of this study is to determine the potential of discarded desiccant silica gel as agent in prolonging the shelf life of lakatan banana. The experiment was laid out in completely randomized design and replicated thrice. The lakatan banana stored with ethylene absorbent (10 grams silica gel) and in conventional way without ethylene absorbent. The physiological loss of lakatan banana, in terms of the pulp to peel ratio, set up without ethylene absorbent documented minimum weight loss of (1.65g) recorded with spoilage at the end of 7 days storage. The banana with ethylene absorbent (10 grams silica gel) documented with (1.57g) recorded no spoilage respectively up to 7 days storage. In terms of Peel color banana without ethylene absorbent data shows most evident change in peel color and some of the banana turns black which shows that the banana is overripe and already in decaying process compared to set up with ethylene absorbent (10 grams silica gel) shows the peel color of the banana are still good recorded with no spoilage. Total soluble content remained high in set up with ethylene absorbent (10 grams silica gel) with (17.37%) compared to the set up without ethylene absorbent (15%). Hence, It was concluded that silica gel can successfully prolong the shelf life of lakatan banana.
