Lactose is a sugar that is found most notably in milk. Lactose makes up around 2~8% of milk (by weight), although the amount varies among species and individuals. It is extracted from sweet or sour whey.
Pharmarceutical lactose products is an extra from the milk to separate out the product, the pharmaceutical, food, health care roducts such as the production of essential accessories for the pharmaceutical carriers and excipients.
Properties: white crystal or crystalline powder, slightly sweet taste, the relative density 1.525 (water-bearing materials), soluble in water, in ethanlo, insoluble in chloroform or ether.

Applications of Lactose
1. A fermented milk is essential to provide the carbon source. Under the action of lactic acid bacteria, lactose, galactose and glucose is decomposed into.
2. Provide nutrition to provide energy for mankind. Galactose has important influence on the development of the mammalian nervous. Lactose is conducive to the absorption of calcium. Lack of lactase causes lactose intolerance.
3. Dairy organizations have an important impact on the state. Milk production, the impact on the crystallization of lactose milk taste. Solubility milk.
4. Has an important influence on the color of dairy flavor. Browning reaction. After fermentation flavor formation.
Lactose is a naturally occurring simple carbohydrate, or sugar, found only in the milk of mammals.
For this reason, it is also commonly referred to as "milk sugar." All commercial lactose is obtained from the milk of cows as a by-product of the dairy industry. Chemically, lactose is the disaccharide of the simple sugars D-galactose and D-glucose (Figure 1). In other words, the lactose molecule comprises one molecule of D-galactose chemically linked to one molecule of D-glucose. Lactose exists in two isomeric forms, known as alpha and beta (designated a-lactose and b-lactose).
