The fermentation process is a natural metabolic pathway where microorganisms, such as yeast and bacteria, convert sugars into acids, gases, or alcohol. This process occurs in anaerobic conditions, meaning it takes place without oxygen. Fermentation is commonly used in the production of various foods and beverages, including bread, yogurt, and beer. During fermentation, the microorganisms break down carbohydrates, releasing energy and producing byproducts like carbon dioxide and ethanol. This not only helps preserve food but also enhances flavors and textures. The process is essential in many culinary traditions and plays a significant role in food science and technology.
