Abstract
Postbiotics are metabolites derived from probiotics and other beneficial microorganisms that due to containing organic acids, bacteriocins, and bioactive peptides possess antimicrobial and antioxidant properties. In recent years, the use of postbiotics as a functional agent for food packaging systems has increased in popularity among researchers. However, although the postbiotics-packaging system has increased gradually, there are some obstacles that challenge it such as the safety and stability of novel beneficial microorganisms like mold as a next generation of postbiotics sources, parameters optimization of preparation and treatments of postbiotics, safety and performance of postbiotic carrier polymer and the sensorial effect of postbiotics on packaged foods. In addition, to ensure the consumption of packaged food with postbiotic-containing polymers, its safety needs to be thoroughly investigated, as research has shown that the postbiotic administration can have negative effects such as gastrointestinal complications, and allergies on the consumer body's health. Finally, for the entry of postbiotics as functional compounds into the food packaging market, the collaboration between academia and industry, clear labeling of packaged food and increasing consumer awareness about postbiotics are essential. Therefore, this study aims to briefly overview of the current status and future directions of postbiotics in food packaging.
