Fermentation
Fermentation is a biological process in which microorganisms, such as bacteria, yeast, or fungi, break down sugars and other organic compounds without oxygen to produce energy. Depending on the type of fermentation, this process produces by-products like alcohol, gases (such as carbon dioxide), or acids. Fermentation is widely used in food production and occurs naturally in various environments.
Functions?
Fermentation can extend the shelf life of food by creating an environment where harmful bacteria cannot grow. This is why many fermented foods, like pickles and sauerkraut, are preserved for long periods. Fermentation can add complex flavors to food and drinks—for example, the tanginess in yogurt or the sourness in sourdough bread results from lactic acid fermentation.

Nutritional benefits?
Fermentation can improve food digestibility and enhance its nutritional profile by breaking down antinutrients (like phytic acid) and increasing the bioavailability of vitamins and minerals.
Additional info?
Many fermented foods contain beneficial bacteria (probiotics), which support gut health and the immune system.
