Summary
Food grade lactose monohydrate is a kind of disaccharide which exists in the milk of mammals, so comes the name. Its molecular structure is condensed and formed by a molecule of glucose and one molecule of galactose. It taste slightly sweet, lactose content is 4% in milk and 5% to 7% in human milk. Industrial Lactose is extracted from whey, it can be used in the manufacture of baby food, candy, artificial milk, etc. In medicine it is used as a flavoring agent.
Properties

Product Detail
【Function】
1, Lactose is essential for fermented milk, it can provide carbon source. Lactose can be broke down into galactose and glucose under the action of lactic acid bacteria.
2, Lactose can provide nutrition and energy for human body. Lactose is beneficial to calcium absorption. Lacking of lactose will cause lactose intolerance.
3, Lactose has an important impact on the organization state of dairy product.
4, Lactose has important impact on color and flavor of dairy products, after browning reaction and fermentation the flavor forms.
5, Lactose can promote calcium absorption
6, Lactose has intestines function and it can prevent constipation.
Application:
It can be used as nutritive sweeteners, excipients, dispersing agent, flavoring agents, nutritional agent.
