Development of edible packaging film from banana peels and effect of glycerol concentration on the film properties

Edible film from banana peel was developed with incorporation of varying levels of glycerol (5, 10, 15 and 20%) as plasticizers. Different parameters including thickness of the edible film, moisture content of the film by hot air oven method, tearing strength, density, water absorption, solubility, water vapor transmission rate(WVTR) and color were studied. The study shows the best result at 10% glycerol concentrations.
