Product Description

1.Product Name:   Lactose

2.CAS NO:   63-42-3 

3.Purity: 99%min

4.Appearance:  White crystalline powder

5.HS Code:   17021100.00

6.Application: 

 

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.
