Functional Properties of Edible Films from Whey Proteins: A Review

Proteins are maj or class of edible biodegradable biopolymers. Whey pro tein is one of the imp ortant protein sources. One ofthe potential uses of this pro tein is fo r production of biodegradable films and coatings. edible. biodegradable fi lms and coatings, by acting as barriers to control the transfer of moisture, oxygen, carbon dioxide, lipids, and flavor comp ounds, can prevent quality deterioration and increase the shelf life of the food products. In addition, edible films or coatings may provide mechanical integrity and imp rove the handling characteristics of the food. They can be effec tive carriers ofmany junctional ingredi ents, such as antimicrobial agents to improve safety and stability offoods, antioxidants to prevent lip id oxidation, and fla vorings and pigments to improve quality offoods . in this manuscript, physico chemical properties ofthese films (including water vapor and oxygen barrier properties, mecha nical, thermal and thermomechanical prope rties) were investigated.
