Novel Approaches in Establishing Chemical Food Safety Based on the Detoxification Capacity of Probiotics and Postbiotics: A Critical Review
This review examines emerging evidence that probiotics and their metabolic byproducts (postbiotics) can help neutralize environmental contaminants in food, including bacterial toxins, mycotoxins, pesticides, heavy metals, and microplastics. Researchers found that various probiotic strains can bind to, transform, or break down these harmful substances through multiple mechanisms. The study highlights biological approaches using beneficial microorganisms as a practical and cost-effective strategy for improving food safety.
