Preparation and characterization of biodegradable film based on skin and bone fish gelatin

Biodegradable films can act as excellent oxygen, water, and lipid barrier. Gelatin is utilized extensively as a gelling agent, emulsifier, stabilizer, adhesives, viscosity agent, binder agent and film-forming agent. Fish gelatin as a film-forming agent has unique characteristics but varies depending...

Summary:Biodegradable films can act as excellent oxygen, water, and lipid barrier. Gelatin is utilized extensively as a gelling agent, emulsifier, stabilizer, adhesives, viscosity agent, binder agent and film-forming agent. Fish gelatin as a film-forming agent has unique characteristics but varies depending on fish species. The study aims to characterize biodegradable film made using skin and bone fish gelatin with the addition of plasticizer. Gelatin of ocean fish, spotted oceanic triggerfish (Canthidermis maculata), and freshwater fish, tilapia (Oreochromis niloticus) were used. As a plasticizer, glycerol or sorbitol with concentrations of 0.25 and 0.5 % was added. Gelatin of spotted oceanic triggerfish resulted in film with higher tensile strength, whereas tilapia gelatin with glycerol produced biodegradable film with higher elongation and water vapor permeability. The best characteristics of biodegradable film made from gelatin of spotted oceanic triggerfish with 0.25% sorbitol.
