Growing evidence of the link between gut microbiota and human health has created interest in dietary modifications that can impact microbial activity and host responses. Although probiotics and prebiotics have been widely studied for this purpose, it can be complex to preserve the viability and effectiveness of living microorganisms throughout food processing and storage. This has drawn attention to postbiotics, a relatively new class of microbial-derived alternatives that contain inanimate microorganisms and/or their constituents that have been shown to promote the host's health.Postbiotic preparations may contain inactivated bacterial cells, and their components such as cell-wall structures, proteins, polysaccharides depending on the microbe and processing applications. Certain preparations may affect immunological responses, inflammatory signaling, intestinal barrier function, and interactions within the gut microbial population, according to experimental data. Recent studies on humans have also shown that certain postbiotic preparations are useful, especially for specific immunological outcomes and gastrointestinal problems. From a food technology perspective, postbiotics have potential due to their non-viable nature, which may provide more processing and storage flexibility than live probiotic cultures. However, there are still significant variations in microbial strains, production techniques, inactivation processes, composition, and dose in the field. Furthermore, while human clinical evidence is still very limited, a large portion of the current evidence is derived from laboratory and animal investigations. The current understanding of postbiotics, their main compositions, sources and manufacturing, methods of action, possible roles in human health and the gut, uses in functional foods, safety concerns, research constraints, and future possibilities are all included in this study. Overall, postbiotics represent a promising area at the intersection of food science, microbiology, and nutrition, although stronger clinical evidence and standardized approaches are needed to support their wider application.
