Description

Phosvitin is a highly phosphorylated protein primarily derived from egg yolk, known for its exceptional metal-chelating and antioxidant properties. Its unique structure, rich in phosphoserine residues, makes it a valuable functional ingredient for controlling oxidation and enhancing mineral bioavailability. This product is essential for manufacturers in the nutraceutical, food science, and biomedical research sectors seeking natural, multifunctional additives. Phosvitin CAS NO 9008-96-2 offers a versatile solution for applications requiring natural emulsification, stabilization, and bioactive delivery.

Application

• Nutraceutical & Dietary Supplements: Utilized as a natural mineral carrier (e.g., for iron, calcium) to improve absorption and as an antioxidant ingredient.
• Functional Food & Beverage Fortification: Acts as an emulsifier, antioxidant, and stabilizer in products like dairy alternatives, health drinks, and fortified foods to prevent lipid oxidation.
• Biomedical & Cosmetic Research: Investigated for its bioactive properties in wound healing, anti-aging formulations, and as a carrier for drug delivery systems.
• Food Preservation: Applied as a natural antioxidant coating or additive in meat, seafood, and poultry products to extend shelf life and maintain color.
• Biochemical Research & Reagent: Serves as a standard or key reagent in studies of phosphoprotein chemistry, metal-protein interactions, and enzymatic activity.
• Animal Feed & Pet Food: Incorporated as a functional protein source to enhance mineral nutrition and antioxidant status in premium feed formulations.
