Edible composite packaging has the advantage of complementary functional properties over its individual bio-components. However, film composites made from caseinate (CA) and carboxymethyl chitosan (CMCH) have not yet been well explored. In this study, four types CA-CMCH films were prepared evaluated with without transglutaminase (TGase) supplement. Aqueous CA (8%, w/v) CMCH solutions (2%, mixed...
