Description

β-Galactosidase is a vital hydrolytic enzyme that catalyzes the breakdown of lactose into its constituent monosaccharides, glucose and galactose. This catalytic activity is essential for addressing lactose intolerance and improving the functionality of dairy products. It is a critical reagent for the food & beverage, pharmaceutical, and diagnostic industries, where precise enzymatic activity and high purity are paramount for product quality and process reliability.

Application

• Lactose-Free Dairy Production: Hydrolyzes lactose in milk, yogurt, ice cream, and whey to create products suitable for lactose-intolerant consumers.
• Food Ingredient Processing: Used to enhance sweetness, improve texture, and prevent crystallization in various food systems.
• Pharmaceutical Intermediates: Employed in the synthesis of oligosaccharides and other bioactive compounds.
• Diagnostic & Analytical Reagents: Serves as a key component in clinical assay kits for detecting specific biomarkers or enzymatic activity.
• Biotechnology Research: A fundamental tool in molecular biology for assays involving β-galactoside substrates (e.g., lacZ gene reporter systems).
• Animal Feed Additive: Improves digestibility and nutritional value of feed containing dairy by-products.
