Product Details

β-Galactosidase#9031-11-2

β-Galactosidase (CAS No. : 9031-11-2) is a glycoside hydrolase capable of catalyzing the hydrolysis of β -galactosidic bonds. It is widely present in microorganisms, plants and animals, and its product characteristics and application scenarios are significantly diverse. In terms of physical properties, most commercially available products are white to light yellow powders or liquid preparations. Powder products have better fluidity and are convenient for storage and transportation. Liquid preparations, on the other hand, may be light yellow to light brown transparent or slightly turbid liquids, and buffers or stabilizers are often added to maintain activity.

Product Usage

β-Galactosidase (CAS No. : 9031-11-2) has a wide range of applications, with the core being its characteristic of catalyzing the hydrolysis of β -galactosidic bonds: In the food industry, it is mainly used in the production of low-lactose dairy products (such as lactose-free milk and ice cream) to solve the problem of lactose intolerance. It is also used in whey processing to recover lactose, synthesize functional oligosaccharides (such as galactooligosaccharides), and clarify fruit juices.
