Solid-State Fermentation for the Recovery of Phenolic Compounds from Agro-Wastes

This review article analyzes the extraction of polyphenolic compounds from agro-wastes using solid-state fermentation, highlighting its potential in the food, cosmetic, and pharmacology industries. It discusses the impact of various extraction parameters, such as substrate, temperature, pH, microorganism inoculum, moisture, and water activity, on the concentration and recovery of these compounds. The study emphasizes the use of agro-industrial wastes like peels, seeds, and fruit pulp as valuable sources of polyphenols due to their biological properties. Solid-state fermentation is presented as an innovative, environmentally friendly method that adds value to agrifood products from agro-industrial wastes.
