Description

Isobetanin is a high-purity, natural betacyanin pigment and a key isomer of betanin, prized for its vibrant red-violet color. Its stability and natural origin make it a critical ingredient for manufacturers seeking clean-label, plant-based colorants to meet modern consumer demand. This compound is essential for the food, nutraceutical, and cosmetic industries, where consistent color performance and regulatory compliance are paramount.

Application

• Natural Food Coloring: Used as a stable red-violet colorant in dairy products (yogurts, ice cream), confectionery, beverages, and fruit preparations.
• Nutraceutical & Dietary Supplements: Incorporated into capsules, tablets, and health drinks for its color and potential antioxidant properties associated with betalains.
• Cosmetics & Personal Care: Provides natural coloration in lipsticks, blushes, and other makeup products, appealing to the clean beauty market.
• Pharmaceutical Coloring: Employed to color coatings of tablets and capsules without using synthetic dyes.
• Laboratory Research & Standards: Serves as a reference standard (CAS 15121-53-6) for analytical testing, method development, and biochemical research on betalains.
• Functional Food Development: Explored in fortified foods and beverages for its dual role as a colorant and a bioactive compound.
