●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
