Lactase, also known as β-galactosidase, is a kind of digestive enzyme in the human body. It is the most important digestive enzyme in infants and young children whose main source of nutrition is breast milk/milk powder. The main function of lactase is to digest lactose and hydrolyze lactose into galactose and glucose that can be absorbed by the human body. Lactase also has the transfer function of galactosidase, galactose to lactose generated galactooligosaccharide, as a bacteria-acting factors for the development of functional foods.

1. Prevent lactose indigestion

1. Catalytic decomposition of lactose: Lactase is mainly used in the dairy industry, using its hydrolysis to decompose lactose in dairy products and produce low lactose or lactose free dairy products. In addition, acid lactase can be made into lactase preparations for the treatment of symptomatic lactose intolerance, especially for infants who take dairy products as the main source of nutrition. Also, it can be added to milk powder to make milk powder for special purposes.
2.Transfer of galactoside: Galactooligosaccharides(GOS) which can promote proliferation of probiotics can be produced by its transfer of galactoside.
How to use it?
Lactase can be used as aid digestion agent in dietary supplements. Moreover, it applies to add in yoghurt in food processing. It can also be used for the production of functional galactooligosaccharides due to its transglycosylation effect.
If people take lactase as a supplement, the most common dose is 300 mg per day, but some people can take up to 810 mg per day.
