Abstract
The experiment was conducted to evaluate the suitable packaging materials for shelf life extension of Assam lemon fruit at ambient condition. During storage, physico-chemical changes were determined at 7, 21, 35, 56 and 77 days of storage using perforated (2, 6 and 10 pin hole) and non-perforated PP (Polypropylene), LDPE (Low density polyethylene) and LDHM (Low density high molecular weight), and control. The rate of change (Total soluble solids, titratable acidity, ascorbic acid and chlorophyll) in packed fruit was comparatively slower as compared to that of control fruits. The present study revealed that packaging of fruits in perforated 2 pin hole PP had distinct advantages over control and other packaging materials in respect of shelf life extension besides retention of quality and nutritional value of the fruits. Assam lemon can be stored up to 21 ±1.00 days only in ambient conditions whereas extension of shelf life up to 77 ±1.41 days is possible by packing the fruits in perforated 2 pin hole PP and this could be suggested for obtaining the optimum and desirable qualities of the fruits with a better shelf life.
