Lactase activity

Applications

Lactase Enzyme is mainly used in the dairy industry. The low-sweetness and low-solubility lactose can be converted into sweeter, more soluble monosaccharides (glucose and galactose). The possibility of precipitation of lactose crystals in ice cream, condensed milk, and evaporated milk is reduced, and sweetness is increased at the same time.

In the fermentation and baking industry, lactose, which cannot be utilized by general yeast, can be hydrolyzed into glucose.

A certain number of infants have diarrhea after feeding milk due to a lack of normal lactase in the intestines. Therefore, many countries often add lactase to milk for infants to drink.
