Description

Violaxanthin is a naturally occurring xanthophyll carotenoid pigment found in various plants and algae. It serves as a key intermediate in the plant photoprotective xanthophyll cycle and is valued for its potent antioxidant properties. This high-purity compound is essential for research and development in the nutraceutical, cosmetic, and food colorant industries, where its natural origin and bioactivity are significant advantages.

Application

• Nutraceutical & Dietary Supplements: Used as an active ingredient in antioxidant formulations and vision health supplements.
• Cosmetic & Personal Care: Incorporated into skincare products for its antioxidant and potential anti-aging benefits.
• Food & Beverage Coloring: Functions as a natural yellow-to-orange colorant in food products.
• Animal & Aquaculture Feed: Added to feed to enhance the coloration of poultry, fish, and crustaceans.
• Pharmaceutical Research: Serves as a reference standard and an intermediate in the study of metabolic pathways and oxidative stress.
• Plant Physiology & Biochemistry Studies: Critical for research on photosynthesis and photoprotection mechanisms in plants.
