Postbiotics, products, or metabolites secreted by living probiotic bacteria like thioic acids, peptides, enzymes, peptidoglycan taken peptidoglycans, polysaccharides, organic acids and cell external proteins, are said at be produced during the bacterial fermentation process. Postbiotics may provide immunization, anti-oxidant, Prevents inflammation, low cholesterolemic, antimicrobial, antagonistic obesity, contrast hypertensive and diabetic retinopathy, impacts. This work attempted to show the antimicrobial performance of postbiotics. In this regard, we consider microbial strains used as postbiotic sources and also postbiotics as antimicrobial agents in food products. Studies show that as probiotics are fed special forms of fiber (prebiotic) molecules, indicate substances known as postbiotics. Short chain fatty acids like acetate, propionate, and butyrate are among in between broadly studied postbiotics. The process of extraction and purification of postbiotics is performed by centrifugation, dialysis, and freeze-drying. These features show that postbiotics assist to increase host health by increasing certain physiological functions. On the other hand, postbiotics can be used to increment the Useful lifetime various Foodstuffs, including dairy products. Research has shown that the addition of postbiotic powder resulting from freeze-drying of these products can prevent mold spoilage. This is due to the antimicrobial effects of postbiotic compounds. It is said that in the near future we will see significant advances in the biological preservation of food.
