Storage Study of Custard Apple Seed Powder

Abstract

The present study was conducted to study the changes in physical and chemical properties of custard apple seed powder packed in LDPE, HDPE & LAF packaging under normal and vaccum packaging conditions. Physical properties viz. water absorption capacity, water solubility index, bulk density, pH & Titratable acidity whereas chemical properties viz. moisture, fiber, fat, protein & carbohydrate content of custard apple seed powder packed in different packages under different storage conditions were determined at an interval of 15 days for a period of 60 days. The Physical properties viz. water absorption capacity, water solubility index, bulk density & pH of custard apple seed powder were observed to be decreased with the storage period whereas its Titratable acidity was increased with the storage period. Moisture content of custard apple seed powder was increased with storage time while its other chemical properties viz. fiber, fat, protein & carbohydrate content were decreased with storage time. Vacuum packed custard apple seed powder could be safely stored in laminated aluminum foil up to a period of 60 days.
