Barley malt extract is a sweet, treacle-like substance used as a dietary supplement and a natural sweetener. It is produced by extracting maltose from sprouted, malted barley. Barley malt extract is used in the bread and baked goods industry for browning and flavoring, and in cereal manufacture to add malt flavor. It is also used in the brewing of beer. Barley malt extract contains approximately 65 percent maltose, 30 percent complex carbohydrates, and 3 percent storage protein. It is a nutritive sweetener and a source of fermentable material, yeast food, browning and flavoring agents, color, sweetener, and enzyme source.
