CAS 9031-11-2 Food grade β-galactosidase Acid Lactase
Product Description
Lactase is also named β-galactosidase, derived from the Aspergillus Oryzae. It's a food grade enzyme which produced from submerged fermentation.It can be used as digestive aid in the dietary supplements.
Action Principle
The lactase can hydrolyze the β-glycosidic bond of lactose molecule into glucose and galactose.

Function/Application
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.
