Description

β,β-Caroten-3-One is a naturally occurring ketocarotenoid, also known as echinenone, which serves as a key intermediate in the biosynthesis of astaxanthin. This compound is valued for its potent antioxidant properties and its role as a natural colorant, providing a distinctive orange-red hue. It is primarily utilized by manufacturers in the nutraceutical, cosmetic, and animal feed industries seeking high-purity, bio-active ingredients.

Application

• Nutraceutical & Dietary Supplements: Used as an active antioxidant ingredient in formulations targeting cellular health and wellness.
• Cosmetics & Personal Care: Incorporated into skincare products (e.g., creams, serums) for its antioxidant benefits and as a natural colorant.
• Animal Nutrition (Aquaculture & Poultry): Employed as a pigment source in feed to enhance the natural coloration of salmon, shrimp, egg yolks, and poultry skin.
• Food Coloring (where approved): Functions as a natural color additive for food and beverage products.
• Pharmaceutical Research: Serves as a reference standard and an intermediate in the synthesis of other carotenoid-based active pharmaceutical ingredients (APIs).
• Functional Food & Beverages: Added to fortified foods and drinks to boost antioxidant content and visual appeal.
