High Quality Invertase, Dextranase & Lactase

LactaseLactase is also named β-galactosidase, derived from the Aspergillus oryzae, it's afood grade enzyme
which produced from submerged fermentation. It's widely used in the dietary supplements as adigestive
aid to reduce the lactose intolerance.Action Principle
The lactase can hydrolyze the β-glycosidic bond of lactose molecule into glucose and galactose.Product Characteristic

Enzyme activity definition: One lactase unit is defined as the quantity of enzyme that will liberate o-nitrophenol at arate of 1µmol per minute under the condition of hydrolyze onPG at 37ºC and pH 4.5.Packaging and Storage
Packaging: 25kg/drum
Storage: store at room temperature, away from light, cold storage is better.
Shelf life: 2years.Application
When people consumed the dairy products or lactose-containing food, as alack of lactase in the body, the lactose is digested and fermented by intestinal bacteria and forms amass 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 ahigh 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 adose of 4,000~6,000 ALU with each lactose-containing meal. For very sensitive lactose-intolerant consumers (need a100% conversion), 10,000 ALU per meal is recommended.
Other application: Apply to process free-lactose yoghurt.
DextranaseDextranase, called alpha glucanase. It's ahigh-yielding strain from Chaetomium gracile screened by mutagenesis, which is through liquid deep fermentation extract from refining. It's widely used in the field of sugar, toothpaste and etc..Action Principle
Dextranase is ahydrolase for specificity splitting decomposition α-1, 6-glucoside linkages of dextran molecule, which outcome production are mainly isomaltose, isomalto-oligosaccharides and glucoseProduct Characteristic
Temperature range: 35ºC~65ºCoptimum temperature: 55ºC~60ºC
pH range: effective pH 3.0~8.0optimum pH: 5.0~6.0Product Feature
Product specification: light yellow liquid/ powder, enzyme activity: 50000U/g.
Activity definition: one dextranase unit is defined as the quantity of enzyme that will liberate reducing sugar at arate of 1µmol per minute under the condition of hydrolyze dextran (2% dextran T2000) at 55ºC and pH5.5 within 10min.Packaging and Storage
Packaging: 25kg/drum
Storage: optimal cold storage near 4~5ºC
Shelf life: 2yearsApplication Method
Sugar industry: In the sugar industry, leuconostoc mesenteroides streptococcus and other microorganisms are through secretion glucansucrases catalyze sucrose to glucose, glucose further polymerized to form dextran. The dextran is ahigh molecular weight polysaccharide polymer, and the type of glycosidic linkage is mainly α-1, 6glycosidic bond. The existence of dextran will have serious impact on sugar production, obviously increasing the viscosity of sugar, reducing the sugar filtration, so that crystallization of sucrose generate abnormal morphology crystals, increase the sugar costs while affect product quality. The use of dextranase can effectively improve the speed of heating cane juice, shorten time to clarify and crystallize, to eliminate the adverse impact of crystallization, thereby improve the production efficiency and yield of sugar.
Other use: The addition of dextranase in toothpaste and mouthwash has good effect on prevention and treatment of dental caries and gingivitis.
InvertaseInvertase, named as Saccharase, fructofuranoside fructohydrolase (EC.3.2.1.26). This product was produced by Saccharomyces cerevisiae strain, which fermented in submerged medium. Saccharase could be used as the additives, ingredients, and the biocatalyzer in the fields of food, beverage, alcohol fermentation, and pharmaceutical preparation etc..Action Principle
Invertase can specifically hydrolyze the fructofuranoside in the non-reducing sugar, and can catalyze the sucrose hydrolysis to produce glucose and fructose.Product Characteristic
Optimum temperature: 45~55ºC
Optimum pH: 4.5~5.5Product Feature
Appearance: Offwhite powder
Enzyme activity: 60000 SU/g
Enzyme activity definition:
A sucrase unit SU is under prescribed conditions (pH4.5, 20ºC, 5.4% (w/v) sucrose solution hydrolysis for 30 minutes), the amount of enzyme which convert 1mg sucrose into glucose and fructoseu in 5minutes.Packaging and Storage
Packaging: 25kg/drum
Storage: We recommend to store the product under the environment with temperature <25ºC, humidity <50%, and the best temperature is 4ºC~10ºC.
Shelf life: 2yearsApplication
The invertase can hydrolyze the sucrose, and produce invert syrup which include glucose and fructose(1:1 proportion).
This invert syrup can inhibit sucrose crystallization and improve the sweetness, enhance the taste, flavor and color in food.Dosage
Add 350g invertase into 1MT sugar syrup(70%, 50ºC), it will be completely hydrolyzed in 6hours. If you focus on the cost, you can add 150g invertase into 1MT sugar syrup(70%, 50ºC), and it will be completely hydrolyzed in 12 hours.
Package: 25kg/drum or as your request.
Storage Situation: Stored in acool and dry well-closed container. Keep away from moisture and strong light/heat.
Shelf Life: Two years when properly stored.
