AI Article Synopsis

  • Chitosan, derived from chitin, is a highly abundant polymer gaining popularity in the food industry for its biodegradable films and coatings, especially when enhanced with plant extracts for better antimicrobial and antioxidant effects.
  • These enriched chitosan films and coatings not only support the demand for environmentally friendly, synthetic preservative-free foods, but also show promising results in improving the quality and safety of various food products.
  • Despite its beneficial properties, further research is needed to expand the use of bioactive chitosan coatings across more food applications and industries, ultimately aiming to reduce plastic usage.

Article Abstract

Chitosan is the deacetylated form of chitin regarded as one of the most abundant polymers and due to its properties, both chitosan alone or in combination with bioactive substances for the production of biodegradable films and coatings is gaining attention in terms of applications in the food industry. To enhance the antimicrobial and antioxidant properties of chitosan, a vast variety of plant extracts have been incorporated to meet consumer demands for more environmentally friendly and synthetic preservative-free foods. This review provides knowledge about the antioxidant and antibacterial properties of chitosan films and coatings enriched with natural extracts as well as their applications in various food products and the effects they had on them. In a nutshell, it has been demonstrated that chitosan can act as a coating or packaging material with excellent antimicrobial and antioxidant properties in addition to its biodegradability, biocompatibility, and non-toxicity. However, further research should be carried out to widen the applications of bioactive chitosan coatings to more foods and industries as well was their industrial scale-up, thus helping to minimize the use of plastic materials.
