Description

Lactalbumin (Alpha Cow Milk Reduced) is a high-purity protein fraction derived from bovine milk, specifically the α-lactalbumin component with its disulfide bonds reduced. This product is valued for its excellent nutritional profile, high digestibility, and functional properties in specialized formulations. It serves as a critical ingredient for manufacturers in the nutraceutical, infant nutrition, sports nutrition, and high-value food sectors seeking premium protein sources with specific amino acid profiles.

Application

• Infant Formula & Clinical Nutrition: As a primary protein source to mimic the amino acid composition of human milk, supporting optimal growth and development.
• Sports & Performance Nutrition: Key component in protein powders, bars, and ready-to-drink supplements for muscle recovery and synthesis due to its high branched-chain amino acid (BCAA) content.
• Medical & Dietary Foods: Used in enteral and parenteral nutrition products for patients with specific metabolic needs or malabsorption issues.
• Functional Food Fortification: Incorporated into yogurts, beverages, and baked goods to enhance protein content and nutritional value.
• Biopharmaceutical Research: Serves as a substrate or standard in enzymatic studies and biochemical research.
• Cell Culture Media: Used as a component in specialized serum-free media formulations for biotechnology applications.
