Application of Bio-nanocomposites in Food Packaging

The need for food packaging to maintain quality and shelf life is increasing day by day. Nanostructured materials are preferred over microstructures due to their unique physical and chemical properties and improved performance. Advanced packaging based on nanotechnology has made it possible to preserve and transport food safely without changing the taste and quality. In addition, it prevents contamination and preserves the mechanical, physiological, physical and chemical properties of food. Various nanomaterials have been used in food packaging to prepare improved, active, smart and bio-based packaging. Smart packaging ensures food safety by detecting contamination, gases, humidity, temperature and other food parameters using sensors. With the increasing demand for the production of new, environmentally friendly and high-performance packaging, "bio-nanocomposites" have attracted a lot of attention in recent years. Bio-nanocomposites are bio-based polymers that consist of two main components, one acting as a matrix called biopolymer (continuous phase) and the second as a reinforcing agent (dispersed phase) with dimensions ranging from 1 to 100 nm. . Bio-based packaging is a new and new generation packaging that replaces natural polymers with synthetic plastics. In this article, recent research in the field of bio-nanocomposites has been reviewed based on the application for different needs and the possible risk of nanoparticle migration.
