Lactose Monohydrate, chemically known as lactose monohydrate, is a white crystalline powder, which is mainly composed of lactose combined with a water molecule. It is widely used in the fields of food, pharmaceuticals and laboratory research. As a sweetener, Lactose Monohydrate has low sweetness and is mainly used to improve the taste and flavor of food while providing certain nutritional value. It is also often used as an auxiliary material in food processing to help mix and stabilize other ingredients. Due to its characteristics as a nutritional sweetener, lactose monohydrate can be found in various foods and beverages, including baby food, candy and dairy products.

In the laboratory, Lactose Monohydrate is often used as an analytical reagent and chromatographic reagent. It plays an important role in chromatographic separation and analysis, especially in the preparation and separation and purification process. It is also one of the important components for the preparation of biological culture media because it can provide the necessary carbon source and nutritional support for the growth of microorganisms. This makes it play an indispensable role in the fields of microbiology and biotechnology. In the medical field, Lactose Monohydrate also has special uses. It can be used to treat constipation because lactose can promote intestinal peristalsis during digestion, thereby helping defecation. In addition, lactose monohydrate is also used to treat hepatic encephalopathy, a condition usually caused by liver failure. Lactose can reduce ammonia levels in the body, thereby improving the patient's cognitive function.
