Abstract


Gelatin is an important natural biopolymer protein extracted from fibrous insoluble collagen and broadly used by various industries because of its stabilizing, and easy handling usage. Nowadays, scientists are interested to find out the alternative polymer of plastic, provide food safety as well having the properties of rapid degradation and environmental friendly. In this study, an investigation was carried out to figure out the property of gelatin as a bioplastic polymer. Gelatin based biofilms are produce in laboratory by solution casting method in Petri plates. The prepared biofilms characterized by tensile strength, break point elongation, swelling behavior, thermogravimetric analysis and degradation. Kinetic studies of pyrolysis of gelatin was investigated by using Friedman method and integral method apparent activation energy (E) were evaluated at constant heating rate. Food coating test were also employed to analysis the gelatin coating protection on food materials.
