Fermentation

Definition

Fermentation is a metabolic process that converts sugars into acids, gases, or alcohol using microorganisms such as yeast and bacteria. This natural process is key in creating traditional foods and beverages, enhancing flavors, preserving food, and improving digestibility. Fermentation also contributes to the cultural identity of various communities, reflecting their culinary heritage and practices.
