Lactase (β-Galactosidase, EC 3.2.1.23), also known as β-galactosidase, hydrolyzes lactose to produce glucose and galactose. The lactase produced by the company is derived from Aspergillus oryzae and is a food grade lactase preparation purified by a biological fermentation method.

Lactose needs to be decomposed into two kinds of monosaccharides such as glucose and galactose by lactase to be absorbed by the body. If the permanent or temporary lactase deficiency in the body, lactose can not be fully decomposed, it will form a "lactose intolerance" disorder.
