Beneficial effects of postbiotics on food products and its effect on human health: A Critical Review

The human intestinal microbiota is a collection of microorganisms that reside in the gastrointestinal tract and there is a direct link between the presence of beneficial microbiota and the development of immune function, the nervous system and the host metabolic pathways. Therefore, consumption of foods or supplements containing postbiotic compounds is one of the most important strategies to balance the microbiota and improve the health of the host. Evidence suggests that postbiotics do not require survival compared to their parent probiotic cells and can produce health-like effects similar to probiotics. Also, the production and use of postbiotics is safer, more stable and more cost-effective. Postbiotics have biological activity, including immune modulating, anti-inflammatory, antioxidant and anti-cancer activity. In this study, a review of the concept of postbiotics and classification of postbiotics based on type and chemical composition and physiological activities and promising effects on prevention or improvement in treatment methods as well as delaying spoilage and increasing shelf life in food products has been done.
