XKfood LA ( 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’s widely used in the dietary supplements as a digestive aid to reduce the lactose intolerance.
ACTION PRINCIPLE
The lactase can hydrolyze the β-glycosidic bond of lactose molecule into glucose and galactose.

APPLICATION
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 expansion of intestinal tract and the strengthening of intestinal peristalsis. It brings borborygmus, diarrhea, abdominal distension and 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 digest lactose in the stomach, 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 2,500 ALU per 10～13 grams of lactose consumed. We recommend a dose of 4,000～6,000 ALU with each lactose-containing meal. For very sensitive lactose-intolerant consumers (need a 100% conversion), 10,000 ALU per meal is recommended.
OTHER APPLICATION:
Apply to process free-lactose yoghurt.
