Abstract

Utilization of rabbit skin as a food product has not been carried out optimally, it is not in line with the increasing production of meat. The high protein content makes rabbit skin potential to be used as gelatin. Gelatin is a protein-derived compound that has translucent, colorless, and tasteless properties. This makes gelatin suitable as a raw material for the manufacture of edible films. Edible film is a packaging layer for edible food products. film The added glycerol plasticizer can affect the characteristics. This study aims to determine the right concentration to obtain moisture content, film, and water vapor transmission rate of edible film from rabbit skin gelatin. The method used is an experimental method with a completely randomized design (CRD) with 4 treatments consisting of glycerol concentrations of 5%, 10%, 15%, and 20%. Each treatment was repeated 5 times with observed moisture content, thickness , and water vapor transmission rate. The statistical test used ANOVA’s test, then Duncan's advanced test at the 5% level. The results showed that the effect of glycerol concentration on rabbit skin gelatin gave a different response (P<0.05) with the best concentration of glycerol 10% (P2) on the moisture content, thickness , and water vapor transmission rate of the edible film. Keywords : edible film, rabbit skin gelatin, glycerol, moisture content, thickness, water vapor transmission rate
