What You Need to Know
During fermentation, lactic acid bacteria metabolize lactose or other sugars to produce lactic acid, lowering the pH and creating an environment that favors probiotic survival while inhibiting spoilage organisms. The acidification also modifies the texture and flavor profile of the product. Maintaining optimal temperature and inoculum density is critical to preserve viability and metabolic activity.
