Description

Livetin is a purified protein fraction derived from egg yolk, primarily composed of a mixture of alpha, beta, and gamma livetins. This high-purity biological material is valued for its functional properties and nutritional profile, making it a critical ingredient in advanced formulations. It serves as an essential raw material for manufacturers in the pharmaceutical, nutraceutical, and high-end food industries seeking consistent, reliable, and well-characterized protein components.

Application

• Pharmaceutical Excipients: Used as a stabilizer, emulsifier, or carrier in vaccine adjuvants and certain drug delivery systems.
• Nutraceutical & Dietary Supplements: Incorporated into protein powders, specialized nutrition products, and sports supplements for its amino acid profile.
• Biotechnology Research: Serves as a component in cell culture media, diagnostic assay development, and biochemical research.
• High-End Food Processing: Utilized as a natural emulsifier and texture modifier in sauces, mayonnaise, and other premium food products.
• Cosmetic Formulations: Applied in skincare products for its potential moisturizing and skin-conditioning properties.
• Veterinary Pharmaceuticals: Used in the formulation of vaccines and nutritional products for animal health.
