ABSTRACT
An experiment on the effect of some coating materials on the storage and quality of banana var. Amrita sagar was carried out at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during September 1997 to January 1998. The five materials viz., CaCl2 @ 1%, waxol, Benlate 500 ppm, surfactant (Jet powder) @ 6% , thickener (corn starch) @ 6% and their combinations were considered as coating materials. The longest shelf life was found in wax coated fruits (21 days) with the lowest weight loss per finger (6.89%) while the shortest shelf life was recorded in Benlate treated fruits (9.33 days). The highest weight loss was obtained in CaCl2 treated fruits (25.07%). The highest percentage of total sugars was recorded in control fruits (21.63) and the lowest in wax coated fruits (18.8) at full ripe condition. A moderate high TSS was obtained in wax coated fruits (29 %) as compared to the highest TSS in Benlate treated fruits (30.5%) at full ripe stage. The lowest titrable acidity was also recorded in wax coated fruits (0.47%)
