Desenvolvimento de Filme Biodegradável a partir de Amido de Milho Zea Mays L.

Abstract

The interest in the use of raw materials from renewable resources for the production of food packaging has been growing, due to the environmental impact caused by the synthetic polymers that are usually used. The use of natural substances such as polysaccharides to develop biodegradable functional films has opened up new application perspectives for sustainable packaging materials. Among the polysaccharides that can be used for the production of biodegradable packaging, starch has promising potential for this production, since it is renewable, subject to natural decomposition, widely available at low cost and it can be subjected to heat treatment to obtain thermoplastic starch by using a suitable plasticizer. Taking these aspects into account, the objective of this study is to develop a biodegradable film using corn starch as the main raw material, evaluating its properties and reviewing the studies already carried out in this area.
