Recent progress in the antimicrobial and antioxidant peptide activated film/coatings for food packaging applications: A Review

Peptides produced from food and other protein resources have gained immense interest to the researcher owing to their excellent antioxidant and antimicrobial properties. The inclusion of bioactive peptides into the food packaging system could be beneficial to improve the shelf life of packed food as well as helpful to reduce the use of unhealthy food preservatives. Moreover, owing to consumer awareness, recently there has been a growing interest in safe and biodegradable packaging materials. Therefore, the study on peptide-added functional packaging could be a good approach to fulfil these demands. Reports have already shown that the addition of bioactive functional peptides retard the oxidation of lipids in food as well as inhibits the growth of food-borne pathogens. The application of the peptide-based packaging film has been studied in various food systems and the resulting insight of those work indicates the potential of peptides as an alternative to synthetic food preservatives.
