Fermentation Processes

Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the process in which glucose is broken down anaerobically, meaning in the absence of oxygen. Fermentation is used industrially to produce a wide variety of products, including beverages, food, and pharmaceuticals.There

are two main types of fermentation processes: alcoholic fermentation and lactic acid fermentation. Alcoholic fermentation is used to produce ethanol, which is the alcohol found in beer, wine, and spirits. Lactic acid fermentation is used to produce lactic acid, which is a food additive and preservative.Fermentation
