Description
Beta-Galactosidase (CAS 9031-11-2, EC 232-864-1) is a hydrolytic enzyme that cleaves the glycosidic bond in lactose, releasing glucose and galactose. It is commercially known as lactase and referenced under identifiers including β-gal, S 2107, and SL396. It carries no assigned E-code in the EU.
In dairy processing, beta-galactosidase is added directly to milk or whey streams to produce lactose-free products by enzymatic hydrolysis at controlled pH and temperature. In pharmaceutical manufacturing, it serves as a reporter enzyme in cell-based assays and gene expression systems. Biotechnology applications include glycan synthesis and carbohydrate substrate screening.
The enzyme is supplied as a dry powder in food-grade and technical grades, with food applications subject to FCC compliance and relevant EU food enzyme regulations. It falls under HS code 35079090 and is subject to REACH registration requirements for industrial quantities. Packaging formats vary by supplier and application grade.
