Description

Citraurin is a naturally occurring apocarotenoid pigment responsible for the distinctive orange-red color in certain fruits and flowers. This compound matters as a high-value, natural colorant and a key intermediate in the biosynthesis of other important carotenoids, offering significant potential in the food, cosmetic, and nutraceutical industries. It is needed by manufacturers and R&D professionals in the natural color, dietary supplement, and specialty chemical sectors seeking authentic, bio-derived pigments for product development and research applications.

Application

• Natural Food Colorant: Used to impart orange-red hues to beverages, confectionery, dairy products, and other food items as a clean-label alternative to synthetic dyes.
• Cosmetic & Personal Care Ingredient: Incorporated into formulations for lipsticks, blushes, and skincare products to provide natural coloration and potential antioxidant benefits.
• Nutraceutical & Dietary Supplements: Serves as a bioactive ingredient or a precursor in supplements targeting eye health and antioxidant support due to its carotenoid lineage.
• Pharmaceutical Research: Investigated as a potential therapeutic agent or a biochemical intermediate in studies related to vision, cellular health, and oxidative stress.
• Animal Feed Additive: Utilized in poultry feed to enhance the coloration of egg yolks and bird skin, improving product appeal.
• Biochemical Research: Employed as a standard or reagent in analytical chemistry, metabolic pathway studies, and enzymatic research.
