Lactose Monohydrate CAS 10039-26-6

Lactose, a disaccharide composed of glucose and galactose, is a unique carbohydrate in human and mammalian milk. In the process of infant growth and development, lactose can not only provide energy, but also participate in the process of brain development. Lactose monohydrate is mainly used as diluent in the manufacture of baby food and preparation of drugs, such as pharmaceutical tablets and powders.

Description  

Lactose occurs as a white to creamy white, crystalline powder. It is normally obtained from whey. It may be anhydrous, contain one molecule of water of hydration, or contain a mixture of both forms if it has been prepared by a spray drying process. It is soluble in water, very slightly soluble in alcohol, and insoluble in chloroform and in ether.

 

Application  

Lactose monohydrate is almost white crystalline granules or powder, odorless, slightly sweet. It’s made from whey and is mainly used in food industry, medicine and chemical reagents. There are two isomers of lactose, being monohydrate and anhydrous. Lactose monohydrate is more stable in air and is unaffected by moisture. The sweetness of α-lactose is 15% of sucrose. In food industry, lactose monohydrate functions as a flow agent, humectant, crystallization control agent, and sweetener. It is used in baked goods for flavor, browning, and tenderizing and in dry mixes as an anticaking agent.
