What was done
This narrative review synthesized literature on postbiotics, focusing on establishing definitions, microbial sources (including lactobacilli, yeasts, and fungi), extraction and production techniques, and biochemical profiles (short-chain fatty acids, enzymes, peptides, polysaccharides, peptidoglycans, and teichoic acids). It also evaluated their reported biological activities (antioxidant, anti-inflammatory, antidiabetic, immunomodulatory, antihypertensive, antimicrobial) and summarized the patent landscape for industrial applications.
What was found
The abstract provides no quantitative data or specific numerical results. It qualitatively describes postbiotics as exerting biological effects similar to live probiotics while providing practical advantages in formulation stability and handling because the cells are inactivated.
Why it matters
It provides a broad framework summarizing postbiotics as stable, non-viable functional ingredients with potential utility across food, veterinary, pharmaceutical, and cosmetic applications.
Limits
The review is narrative rather than systematic and provides general conceptual summaries without pooled clinical outcome measures. No specific sample sizes, trial counts, or quantitative effect sizes are provided in the abstract.
