Physical Characteristics of Gelatin-Xylitol Edible Film

This research objective was to obtain a gelatin-xylitol edible film with optimal physical characteristics. Research on the use of gelatin as a raw material for making edible films and xylitol as a plasticizer in making edible films was carried out from December 2022 to March 2023 which took place at the Laboratory of Animal Products Technology, Faculty of Animal Science, Universitas Brawijaya. This study focused on differences in the percentage of xylitol in the manufacture of gelatin-xylitol edible films with 5 treatments, namely T0 (0%), T1 (0.5%), T2 (1%), T3 (1.5%), and T4 (2%) with 3 repetitions each. The results showed the effect of different xylitol administrations on gelatin-xylitol edible films. There was a very significant difference (P< 0.01) in the analysis of the water resistance test, water vapor transmission rate, and thickness; a significant difference (P < 0.05) in the analysis of the elasticity and tensile strength tests; and there was no significant difference (P > 0.05) on the test for water content, solubility, and total solute. Based on the physical characteristics of the gelatin-xylitol edible film, it can be concluded that the addition of 0.5% xylitol produces a good edible film to be used as a product.
