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.
