Development of Biodegradable Polysaccharide-Protein Edible Gel Coat With Antimicrobial Properties for Food Products

Abstract

Food edible coatings are an important milestone in food production and one of the innovations in food packaging development. This article presents materials on the development of the formulation and technology for the manufacture of a novel composite coating based on sodium alginate, chitosan and protein hydrolysate obtained by the electrochemical method of double extraction from cod processing waste to obtain edible coatings for semi-finished fish products. Furthermore, the physicochemical, physical, mechanical and microbiological properties of this material are described.
