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

1. Improve metabolic energy utilization rate of meal like raw material soybean meal, cottonseed meal, rapeseed meal, reduce chyme viscosity, improve animal production performance and increase feed/gain ratio.
2. Completely degrade oligosaccharide of meal like raw materials, reduce nutrients residue in chyme, and increase nutrient utilization rate.
3. Eliminate flatulence, diarrhea of mono-gastric animals, deal to digestive disorders caused by oligosaccharide.
4. Ease or avoid alimentary apparatus compensatory hyperplasia, reduce animal maintenance requirements, improve feed energy valence.
For a long time, lactase production for hydrolysis of milk and milk caramel. It can also be used for the processing of a range of other dairy products such as yogurt, ice cream, desserts, butter and cheese.
We specialize in the manufacture of lactase can be used as aid digestion agent used in dietary supplements.
The role of the enzyme has a transglycosylation, can also be used for the production of functional galactooligosaccharides.
When people consumed the dairy products or lactose-containing food, as a lack of lactase in the body, the lactose is digested and fermented by intestinal bacteria and forms a mass of carbon dioxide gas. It can lead to the expansiodn of intestinal tract and the strengthening of intestinal peristalsis. It brings borborygmus, diarrhea, abdominal distension an so on. It is called lactose intolerance.
The Lactase from Aspergillus oryzae has a high activity at low pH(pH3.5~5.5) making it particularly suitable for
