Lactase, also known as beta-galactosidase hydrolysis of lactose to produce glucose and galactose. Lactase also has the transfer function of galactosidase, galactose to lactose generated galactooligosaccharide, as a bacteria-acting factors for the development of functional foods. Biological enzyme lactase is a non-toxic side effects, by the authority of the FDA, the FCC, the WHO / FAO and JACFA assessment to determine the safety of substances.
Action Principle
Lactase can hydrolyze β-glycosidic bond of lactose molecule into glucose and galactose

The Lactase from Aspergillus oryzae has a high activity at low pH(pH3.5~5.5), making it particularly suitable for digest lactose in acid conditions, and it's therefore ideal for use in the dietary supplements as digestive aid.
The dose of fungal lactase depends on the amount of the lactose and the size of meal consumed, one general guideline is 2,500ALU per 10~13g of lactose consumed. We recommend a dose of 4,000~6,000ALU with each lactose-containing meal.
Other Application
Apply to process free-lactose yogurt.
It can hydrolyze the lactose in the whey to form monosaccharide which can be used by Saccharomyces Cerevisiae.
