Rhodoxanthin
What is Rhodoxanthin?
Rhodoxanthin (CAS 116-30-3), also designated E161F, is a naturally occurring carotenoid pigment found in certain plant species; used commercially as a colorant and antioxidant.
Where is Rhodoxanthin used?
- Food and feed: red-to-purple hues where carotenoid-based coloring is preferred over synthetic dyes
- Animal feed: enhances pigmentation
- Egg yolks, poultry skin and aquaculture species: color intensity affects market value
- Fat-containing products: antioxidant that supports oxidative stability and extends shelf life
- Compound feed blends: carotenoid supplementation alongside other xanthophylls
- Food manufacturers incorporate it as a natural colorant.
Good to know: 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.
