Description

α-Lactalbumin is a globular whey protein and a key component of the lactose synthase enzyme system. It is highly valued for its excellent nutritional profile, containing all essential amino acids, and its unique functional properties in food systems. This protein is essential for manufacturers in the infant formula, sports nutrition, and functional food industries, where it serves as a premium protein source and a critical bioactive ingredient.

Application

• Infant Formula and Clinical Nutrition: A primary protein source designed to mimic the amino acid profile of human breast milk, supporting healthy growth and development.
• Sports and Performance Nutrition: Incorporated into protein powders, bars, and ready-to-drink beverages for its high-quality, rapidly digestible protein content.
• Functional Food & Beverage Fortification: Used to enhance the protein content and nutritional value of products like yogurts, meal replacements, and health drinks.
• Biomedical and Pharmaceutical Research: Serves as a model protein in studies of protein folding, metal-binding properties, and as a substrate for enzymatic assays.
• Cell Culture Media: Employed as a component in specialized media formulations for biotechnology and pharmaceutical applications.
• Cosmeceuticals: Utilized in high-end skincare formulations for its potential bioactive and moisturizing properties.
