Description

Torularhodin is a naturally occurring carotenoid pigment, a valuable member of the xanthophyll family. This compound is prized for its potent antioxidant properties and its ability to impart a vibrant red-orange color. It serves as a key functional ingredient for manufacturers in the nutraceutical, cosmetic, and food industries seeking natural, bioactive solutions. Torularhodin CAS NO 514-92-1 offers a sustainable, bio-derived alternative to synthetic colorants and antioxidants.

Application

• Nutraceutical & Dietary Supplements: Utilized as an active antioxidant ingredient in capsules, tablets, and functional food formulations to support cellular health.
• Natural Food Coloring: Provides a stable red-orange hue to beverages, dairy products, confectionery, and savory snacks as a clean-label colorant.
• Cosmetics & Personal Care: Incorporated into skincare serums, creams, and lotions for its antioxidant benefits and potential skin-protective effects.
• Animal Feed & Aquaculture: Used as a pigment source in feed for poultry, fish, and crustaceans to enhance the coloration of egg yolks, flesh, and shells.
• Pharmaceutical Research: Serves as a reference standard and an intermediate in research focused on oxidative stress and carotenoid metabolism.
• Functional Beverages: Added to health drinks and smoothies for combined color and antioxidant enrichment.
