●Product Name:β-galactosidase

●Synonym:Lactase

●CASno. 9025-35-8

●Product Description:Lactase is 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 and modified milk powder to reduce the lactose intolerance

●Action Principle:The lactase can hydrolyze the β- galactosidase bond of lactase molecule and galactose.

●Packaging and Storage:

▲Storage:Store at room temperature,away from light,cold storage is better.  

▲Shelf:2 years. 

▲Packaging:25kg/drum

●Product Characteristic:

▲Temperature range:5 ºC-65 ºC optimum temperature:55 ºC-60 ºC 

▲pH range:pH3.0-8.0 optimum:4.0-5.5

●Product Feature:

▲Product apppearance:White to light brown powder,the colour may vary from batch to batch.

▲Product odor:Slight odor of fermentation

Standard enzyme activity:No less than 100000ALU/g

▲Enzyme activity definition:One lactase unit is defined as the quantity of enzyme that will liberate o-nitrophenol at a rate of 1 μmolperminute under the condition of hydrolyze oNPG at 37 ºC and pH4.5.

▲Product standard:GB1886.174<>

●Applicetion:

▲When people consumed the dairy products or lactose-containing food,as a lock of lactase in the body,the lactose is digested and fermented by intestinal bacteria and forms a mass of carbon dioxide gas. It drings borborygmus,diarrhea,abdominal distension and so on.It is called lactose.

▲The Lactase from Aspergillus oryzae has a high activity at low pH(3.5-5.5)，making it particularly suitable for digest lactose in the dietary supplements as digestiveaid.

The dose of fungal lactase depends on the amount of the lactose and the siz e of meal consumed,one general guideline is 2,500ALUper10-13g of lactose consumed.We recommend a dose of 4,000-6,000ALUwith eash lactose-containing meal.For very sensitive lactose-containingconsumers(need a 100% conversion),10,000ALUper meal is recommended.

▲Other Application: Apply to process free-lactose yoghurt.It can hydrolyze the lactose in the whey to from monosaccharide which can be used by Saccharomyces cerevisiae
