Postbiotic bioactive packaging systems: A review

Abstract

A bioactive containing packaging system is not only a traditional protective structure for a food product but also offers additional health-benefiting properties. Postbiotics (nonbiotics) are metabolites produced by probiotic microorganisms that have numerous health benefits. The safety and non-toxicity of postbiotics and their capability to prevent the growth of food spoilage microbes are the significant features of postbiotics (cell-free supernatants) in using these components in food manufacturing. In this comprehensive review, authors discuss the characteristics of postbiotics, different types and sources of postbiotics, their application in active packaging and the possibilities of their application in increasing the shelf-life of products with active packaging.
