Product Description
β-Galactosidase (CAS No. 9031-11-2) is a glycoside hydrolase enzyme that catalyzes the hydrolysis of β-galactosidic bonds. It is widely distributed in microorganisms, plants, and animals, with diverse product characteristics and application fields.
In terms of physical form, most commercially available products appear as white to light yellow powders or liquid preparations. The powder form offers good flowability and is convenient for storage and transportation. Liquid preparations are typically light yellow to light brown transparent or slightly turbid solutions, often containing buffers or stabilizers to help maintain enzymatic activity.

Product Application
β-Galactosidase (CAS No. 9031-11-2) has a wide range of applications, primarily based on its ability to catalyze 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, helping to address lactose intolerance issues. It is also applied in whey processing for lactose recovery, the synthesis of functional oligosaccharides such as galactooligosaccharides, and the clarification of fruit juices.
