Presentation title: Postbiotic products as functional food ingredients

Abstract: Of interest is the biological activity of postbiotics and the possibility of their use as functional food ingredients. Postbiotics are products of metabolism and processing of probiotic bacteria, namely, specific enzymes, peptides, teichoic acids, muropeptides, bacteriocins, organic acids, and others. Some postbiotics can cross the intestinal barrier and exhibit systemic antihypertensive, hypocholesterolemic, antioxidant, and immunological properties. Of particular interest is the use and study of the properties of muropeptides (low-molecular degradation products of peptidoglycans of the cell walls of probiotic bacteria) as immunological ingredients of functional nutrition for people with reduced immune status.In this regard, it is necessary to develop a technology for producing low molecular weight muropeptides as immunological functional ingredients
