Phaffia rhodozyma Astaxanthin 5% Powder | Aquaculture Feed

EarthHue Asta-Pure 110 is a 5% astaxanthin powder derived from the red yeast Xanthophyllomyces dendrorhous (formerly Phaffia rhodozyma). This yeast-based astaxanthin offers aquaculture feed producers a reliable, fermentation-derived alternative to both synthetic astaxanthin and algae-derived sources, with proven efficacy in pigmenting salmonid flesh and crustacean shells.

Unlike H. pluvialis astaxanthin, which is predominantly the 3S,3'S stereoisomer, P. rhodozyma produces the 3R,3'R isomer — the same form found in wild salmon and crustaceans. This natural isomer profile makes Phaffia-derived astaxanthin particularly well suited for aquaculture applications where species-specific bioavailability and deposition efficiency are critical. The powder form integrates seamlessly into feed extrusion and pelleting processes.

EarthHue Asta-Pure 110 is manufactured via controlled submerged fermentation in stainless-steel bioreactors, ensuring batch-to-batch consistency, year-round supply independent of climate or light conditions, and freedom from marine contaminants such as heavy metals and microcystins that can affect open-pond algae production.

The product is approved under EU E161j and holds FDA GRAS status for aquaculture feed use. It is suitable for inclusion in feeds for Atlantic salmon, rainbow trout, Pacific salmon, shrimp, and ornamental fish. Feed-grade packaging and stability data are available to support formulation and storage optimization.

For aquaculture nutritionists and feed mills seeking a traceable, fermentation-based astaxanthin that delivers predictable flesh pigmentation without synthetic inputs, EarthHue Asta-Pure 110 is the dependable yeast-derived solution.
