  • Applications

    Lactoferrin (CAS 339615-76-8) is used as a functional protein ingredient across several industries: in food processing and dairy products, it serves as a nutrition-oriented additive with iron-binding capacity and antimicrobial properties; in infant formulas and other functional foods, it is incorporated to reflect the composition of human milk; in cosmetics and personal care, it appears as a bioactive protein ingredient for skin formulations; in animal feed and agriculture, it is included as a feed additive to standardize ingredients and influence microbial balance; and in pharmaceutical and nutraceutical formulations, it is explored as a stabilizer and carrier for bioactives and as a protein-based component in controlled-release systems.
