What You Need to Know
During fermentation, microbes such as lactic acid bacteria, yeasts, and acetic acid bacteria metabolize carbohydrates via glycolysis and fermentation pathways, producing lactic acid, ethanol, CO₂, and a suite of secondary metabolites. The resulting pH drop, gas generation, and enzymatic breakdown of proteins and polysaccharides alter texture, while volatile esters and aldehydes contribute to aroma and taste.
