Where is maltose primarily found?

Maltose is primarily found in grains, particularly in foods derived from barley and other cereals. It is a disaccharide sugar composed of two glucose units and is formed during the process of starch digestion or fermentation. In the context of grains, maltose is produced when the starch breaks down through the action of enzymes, particularly during processes like malting, which is essential in beer production.

While dairy products, fruits, and vegetables contain sugars, they do not have maltose as a primary sugar. Dairy products mainly contain lactose, fruits are rich in fructose and glucose, and vegetables have a variety of sugars but usually not maltose in significant amounts. This specific association of maltose with grains helps understand its metabolic role and prevalence in our diets, particularly in foods like bread, beer, and cereals.
