Rhodoxanthin

Rhodoxanthin (CAS 116-30-3), also designated E161F, is a naturally occurring carotenoid pigment found in certain plant species and used commercially as a colorant and antioxidant.

It delivers red-to-purple hues in food and feed applications where carotenoid-based coloring is preferred over synthetic dyes. In animal feed formulations, it is used to enhance pigmentation.

This additive is vital for egg yolks, poultry skin, and aquaculture species, where color intensity directly affects market value. Food manufacturers incorporate it as a natural colorant where needed.

As an antioxidant, it supports oxidative stability in formulations sensitive to lipid degradation, extending shelf life in fat-containing products. It is essential for agricultural nutrition programs.

It contributes to carotenoid supplementation alongside other xanthophylls in compound feed blends. Rhodoxanthin is typically supplied as a powder or as a standardized concentrate for dispersion.

It is available in feed-grade and food-grade specifications, with purity and carotenoid content defined by the applicable E161F regulatory standards for global compliance.

Buyers should confirm concentration levels and carrier composition when evaluating suppliers, as these vary across the market. Proper storage is required to maintain the potency of the pigment.
