Maltose is a type of sugar known as a disaccharide, which means it is made up of two simpler sugar molecules called glucose. It is commonly found in foods like malted beverages and certain cereals. Maltose is produced during the digestion of starch, a complex carbohydrate, and is broken down by the enzyme maltase in the body. In addition to its presence in food, maltose plays a significant role in the brewing industry, where it is a key ingredient in the production of beer. The fermentation process converts maltose into alcohol and carbon dioxide, contributing to the flavor and texture of the final product.
