Description

β-Carotene is a naturally occurring, fat-soluble organic compound belonging to the carotenoid family, recognized by CAS NO 31797-85-0. It serves as a vital precursor to vitamin A (provitamin A) and is a potent natural colorant and antioxidant. This high-purity ingredient is essential for manufacturers in the food and beverage, dietary supplement, pharmaceutical, and cosmetic industries seeking to enhance product appeal and nutritional value.

Application

• Food & Beverage Coloring: Used as a natural colorant (E160a) in juices, dairy products, confectionery, baked goods, and sauces to provide stable yellow to orange hues.
• Dietary Supplements & Nutraceuticals: Formulated into softgels, tablets, and multivitamin blends for its provitamin A activity and antioxidant properties supporting eye and skin health.
• Pharmaceuticals: Employed in vitamin A deficiency treatments and as an excipient in specialized drug formulations.
• Cosmetics & Personal Care: Incorporated into skincare creams, lotions, and suncare products for its antioxidant benefits and subtle coloring effect.
• Animal Feed & Aquaculture: Added to poultry feed to enhance egg yolk color and to fish feed (e.g., salmon) for flesh pigmentation.
• Clinical & Research Use: Serves as a standard or reagent in biochemical research and analytical laboratories.

Quality Control

Our β-Carotene is produced and tested under strict quality management systems. We offer grades compliant with relevant industry standards such as FCC (Food Chemicals Codex) and USP (United States Pharmacopeia) for food, supplement, and pharmaceutical applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), the container should be kept sealed under an inert gas (e.g., nitrogen) after opening to minimize degradation. Keep away from strong oxidizing agents.
