Description

Xanthophyll is a vital oxygenated carotenoid pigment, widely recognized for its role as a natural colorant and antioxidant. Its significance lies in providing safe, stable, and vibrant yellow to orange hues while offering functional health benefits. This compound is essential for manufacturers in the nutraceutical, food & beverage, animal feed, and cosmetic industries seeking natural ingredient solutions.

Application

• Nutraceutical & Dietary Supplements: Key ingredient in eye health formulas (e.g., AREDS2) for its role in macular pigment, often combined with other carotenoids like Lutein and Zeaxanthin.
• Food & Beverage Coloring: Used as a natural color additive (E161) in products such as beverages, dairy, confectionery, and baked goods to achieve yellow and orange shades.
• Animal & Aquafeed Nutrition: Incorporated into poultry feed to enhance yolk color intensity and into aquaculture feed (e.g., for salmon and shrimp) to improve flesh pigmentation.
• Cosmetic & Personal Care: Employed in skincare formulations for its antioxidant properties, helping to protect skin from oxidative stress and contributing to product coloration.
• Pharmaceutical Intermediates: Serves as a starting material or intermediate in the synthesis of specialized pharmaceutical compounds.
• Research & Development: Used as a standard or reagent in biochemical, nutritional, and photobiological research studies.
