Edible Film from the Pectin of Papaya Skin (The Study of Cassava Starch and Glycerol Addition)

Abstract

The production of edible cooking made from the pectin of papaya skin with cassava starch and glycerol adition had been studied. The usage of pectin of papaya skin was one way to use papaya skin waste in order to raise its economic value. The aim of this study was to study the effect of cassava starch and glycerol concentration on the product qualities and to determine the the best treatment in making a good quality adible film and acceptable by the consumer. This research used completely randomized design in factorial patern with two factors. The first factor was cassava starch concentration (25%, 35% and 45%) and the second factor was glycerol concentration (20 %, 15% and 10). The data were analyzed by Analysis of Variance (Anova) and Duncan’s Multiple Range Test to detect the difference between the treatment. The best treatment was 25% cassava starch addition and 10% glycerol concentration which produced edible film which had moisture content of 21.16%, thickness of 0.023 mm, tensile strength of 1.900 N, elasticity of 14.223%, and vapor transmission rate of 116.963 g/m2/24 hours. So the production of edible film from papaya skin pectin was potential to be developed.
