Fermentation is a natural process where microorganisms, like bacteria and yeast, convert sugars into acids, gases, or alcohol. This process is commonly used in making foods and drinks such as bread, yogurt, and beer. During fermentation, these tiny organisms break down the sugars, producing carbon dioxide and other byproducts that give these products their unique flavors and textures. In addition to enhancing taste, fermentation also helps preserve food. The acids produced during fermentation can inhibit the growth of harmful bacteria, making foods like pickles and sauerkraut safer to eat. Overall, fermentation is a fascinating way that nature transforms simple ingredients into delicious and nutritious foods.
