gamma-carotene

Gamma-carotene (CAS 472-93-5), also referenced as beta,psi-Carotene in technical literature, is a naturally occurring carotenoid pigment that functions as both a colorant and antioxidant precursor. It is used in food, pharmaceutical, and cosmetic applications. Unlike the more prevalent beta-carotene, it offers a distinct carotenoid profile that appeals to formulators seeking broader spectrum carotenoid sourcing.

In food and beverage manufacturing, it contributes orange-yellow coloration to products such as beverages, dairy analogs, and functional foods where natural pigment sourcing is a formulation requirement. Nutraceutical and dietary supplement producers incorporate it as part of mixed carotenoid blends, where the combination of provitamin A activity and antioxidant function supports product positioning.

Cosmetic and personal care formulators use it in skin care preparations where carotenoid-based antioxidant activity is a stated ingredient benefit for high-end topical formulations. Pharmaceutical researchers also evaluate it within carotenoid ingredient matrices for encapsulated or softgel delivery formats, ensuring compliance with USP or FCC standards where applicable.

Gamma-carotene is typically supplied as a crystalline powder or in oil suspension form, depending on the intended application and delivery system requirements for the manufacturer. It is available in food-grade and research-grade specifications, with purity levels commonly confirmed by HPLC. Due to its relative scarcity, it is sourced through specialty carotenoid suppliers.
