Description

(9-Cis,9'-Cis)-7,7',8,8'-Tetrahydro-Y,Y-Carotene is a specific, highly purified stereoisomer of a tetrahydrocarotenoid, a class of compounds known for their potent antioxidant and colorant properties. This precise molecular configuration is critical for applications requiring defined biological activity and consistent performance. It is primarily utilized by manufacturers in the nutraceutical, cosmetic, and specialty food ingredient sectors seeking advanced, research-backed formulations.

Application

• Nutraceutical & Dietary Supplements: As a high-purity active ingredient in antioxidant formulations targeting cellular health and wellness.
• Cosmetic & Personal Care: Incorporated into anti-aging serums, creams, and lotions for its potential skin-protective benefits against oxidative stress.
• Specialty Food & Beverage Colorants: Used as a natural-origin colorant in premium food products where a specific yellow-to-orange hue and stability are required.
• Animal Nutrition: As a value-added component in feed for aquaculture (e.g., salmon, shrimp) and poultry to enhance natural coloration.
• Pharmaceutical Research: Serves as a reference standard or an intermediate in the synthesis of more complex carotenoid derivatives for clinical studies.
• Functional Food Fortification: For enriching products like beverages, dairy alternatives, and snacks with antioxidant properties.
