Description

cis-Norbixin is a natural, water-soluble carotenoid pigment derived from the seeds of the annatto tree (*Bixa orellana*). This compound serves as a vital natural colorant, prized for its ability to impart stable yellow to orange hues in a wide range of applications. It is primarily sought after by manufacturers in the food, beverage, and dairy industries seeking clean-label, plant-based coloring solutions. Its excellent compatibility with aqueous systems makes it a preferred choice for coloring products where synthetic dyes are undesirable.

Application

• Food Coloring: Used to provide yellow to orange shades in cheeses (e.g., Cheddar, Red Leicester), dairy products, baked goods, and snack foods.
• Beverage Industry: Employed as a colorant in fruit drinks, sodas, and sports beverages where water solubility is essential.
• Dairy and Ice Cream: A key colorant for butter, margarine, cream, and ice cream, offering excellent stability in fatty and aqueous phases.
• Cosmetics and Personal Care: Incorporated into products like soaps, lotions, and lipsticks to provide natural coloration.
• Pharmaceuticals: Used as a coloring agent in tablet coatings and liquid medicinal formulations.
• Pet Food and Animal Feed: Applied to enhance the visual appeal of pet food products.
