Abstract

Currently, there is great interest in the study of new ecological technologies searching a harmonious lifestyle with the environment. In this sense, numerous investigations on thermoplastic materials have been conducted as a significant alternative due to their promising applications. In this regard, thermoplastics materials from different biodegradable and edible polymer sources, which can be used in food packaging, films or coatings, have been evaluated as an alternative to replace synthetic materials to contribute to environmental pollution. The aim of this chapter was to study the physicochemical, mechanical and structural properties of biopolymer films for use in the food industry. In this chapter, different components used for the production of biodegradable and edible coatings: biopolymers, plasticizers, antimicrobials and antioxidants are reviewed.

Keywords:

Biopolymers, Edible films, Food industry, Physicochemical and mechanical properties, Thermoplastic material.
