Malt extract is produced from malted barley through a process of hot water extraction without chemicals. The extract is a yellow-brown viscous liquid with a pleasant malty flavor. It contains gluten and must be declared in ingredients lists due to potential allergens. Malt extract is used as a flavoring, coloring, and texture agent in various baked goods, beverages, cereals, and snacks. However, people with celiac disease must avoid it due to potential immune reactions to gluten.
