麦芽糖, or maltose, is a type of sugar that is produced from the starch of grains, particularly barley. It is created during the process of malting, where grains are soaked in water and allowed to germinate. This process activates enzymes that break down starches into simpler sugars, resulting in maltose. It is commonly used in food products, especially in brewing and baking. In addition to its use in food, 麦芽糖 is also a key ingredient in traditional Chinese sweets and desserts. It has a mild sweetness and a unique flavor that enhances the taste of various dishes. As a natural sweetener, it is often preferred over refined sugars in many recipes.
