Citranaxanthin

Citranaxanthin (CAS 3604-90-8), also designated E161i, is a synthetic carotenoid pigment used to impart yellow-to-orange coloration in food, feed, and cosmetic applications.

Where is Citranaxanthin used?

• Food: colorant and antioxidant stabilizer; standardizes color in processed products where natural pigment variability affects batch consistency
• Poultry and aquaculture feed: pigmentation of egg yolks and broiler skin
• Farmed fish flesh: key quality driver for commercial producers
• Cosmetics: stable warm-toned coloration in self-tanners, color cosmetics, and skin-care preparations
• Pharmaceutical and nutraceutical formulators source it for antioxidant-positioned dietary supplements.

Good to know: Supplements often target carotenoid intake for specific health applications. Buyers should confirm specification sheets against their formulation targets before procurement.
