Product Name:beta-D-Galactosidase
English Name:beta-D-Galactosidase
CAS No.:9031-11-2
Aliases:beta-Galactosidase, Lactase
Physical Properties:White to light brown powder or liquid, soluble in water. The optimum pH varies by source: 7.0~7.5 for E. coli, 6.0~7.0 for yeast, and about 5.0 for mold. The optimum temperature is 37~50°C. It catalyzes the hydrolysis of lactose into glucose and galactose.
Uses:Mainly used in the dairy industry to hydrolyze lactose into glucose and galactose, reducing the possibility of lactose crystallization and increasing sweetness. It is also used in fermentation and baking industries to make lactose available for yeast, and can be added to milk for lactose-intolerant individuals.
Technical Specifications:
Enzyme activity definition: One unit of enzyme activity is the amount that produces 1 micromole of glucose per minute from lactose under specified conditions.
Optimum pH: 7.0~7.5 for E. coli-derived enzyme, 6.0~7.0 for yeast-derived enzyme, and about 5.0 for mold-derived enzyme.
Optimum temperature: 37~50°C.
At normal usage concentration, approximately 74% of lactose can be hydrolyzed within 72 hours.
Recommended dosage for milk: 3000 NLU/L.
