Development of Biodegradable Packaging Films and Edible Coatings for Food Products Based on Composite Materials

Abstract

Plastic is undoubtedly the most convenient type of packaging, but at the same time it is not ecologically friendly. The widespread use of packaging materials all over the world makes us think more and more about the harm of plastic to the environment and humans. It does not decompose in natural conditions and accumulates in huge quantities, because it is mostly used as a single-use packaging. Therefore, the development of environmentally friendly biodegradable edible films and coatings is relevant. Edible food packaging is an important step in food production and one of the innovative directions of food packaging development. This article presents materials on the development of the formulation and manufacturing technology of new composite materials based on sodium alginate and chitosan for the production of edible coatings and films. The results of the physical, chemical and bactericidal properties of these materials are presented.
