Fermentation lutein from Xanthophyllomyces dendrorhous — golden yellow-orange powder in an amber glass bottle

Series: Fermentation-Derived

Fermentation Lutein from Xanthophyllomyces dendrorhous — EarthHue Lute-Ferm 120

Lutein (Fermentation)Powder 5%

Overview

Lutein produced by controlled fermentation of the yeast Xanthophyllomyces dendrorhous, then purified and standardised into a free-flowing powder. Unlike marigold lutein, which depends on a crop and a extraction yield, the fermented route gives a stable assay and colour through the year, with no pigment carry-over from the plant matrix. Intended for eye-health and antioxidant nutraceutical positions, water-dispersible colour systems and clean-label formulations.

Frequently asked questions

How does fermentation lutein differ from marigold lutein?
Both deliver lutein, but marigold lutein is extracted from Tagetes erecta petals, so its assay and colour are tied to crop quality and extraction yield, and the powder carries a characteristic matrix profile. Fermented lutein is produced by a controlled yeast process and purified afterwards, which gives a tighter assay, a cleaner colour and year-round availability. For a supplement where the claim is a specific milligram of lutein per serving, the fermented grade gives you a more predictable label value.
Is it lutein or lutein ester?
This grade is free lutein, not lutein ester. Free lutein is the form used most often in eye-health supplements, and it is the one our assay refers to. Esterified lutein has a different fat-soluble profile and a different regulatory treatment in some markets, so if your specification calls for an ester we will quote that grade instead.
Is fermentation lutein suitable for use in dry and liquid supplements?
Yes. The powder is water-dispersible and free-flowing, so it blends into dry powder fills, and it can be dispersed into oil or emulsion bases for softgels and liquids. We can supply a colour-match sample in your own carrier so you can confirm dispersion before scaling up.
What documentation comes with the batch?
A certificate of analysis covering identity, assay, heavy metals by ICP-MS, microbiology and residual solvents, plus an MSDS. Source, allergen and GMO statements and the market-specific regulatory documentation for EU, US, Japan or Korea filing are available on request.

Fermentation Astaxanthin from Phaffia rhodozyma — EarthHue Asta-Yeast 110

Astaxanthin produced by controlled fermentation of the yeast Phaffia rhodozyma, then extracted and standardised into a free-astaxanthin oil suspension. The route removes harvest and seasonality from the supply chain, so assay and hue hold batch after batch and production runs all year. Delivers the same 3S,3′-S active molecule as Haematococcus at a lower cost per kilogram of active, in a grade built for food colouring, feed and nutraceutical formulations.

Fermentation Lycopene from Yarrowia lipolytica — EarthHue Lyco-Ferm 130

Lycopene produced by controlled fermentation of the yeast Yarrowia lipolytica, then purified and held in a stabilised oil suspension. The fermentative route delivers a consistent lycopene assay with no dependence on tomato crop quality, and it keeps working through the winter supply window when field extraction tightens. Built for functional beverages, dairy, meat analogues, bakery and nutraceutical applications that need a clean-label red that holds its hue through processing.

Fungal Fermentation Lycopene from Blakeslea trispora — EarthHue Lyco-Blak 131

Lycopene produced by fungal fermentation of Blakeslea trispora and supplied as a high-assay coated powder. This is the classic fermentation route for lycopene and the one behind most of the published safety and stability history, which makes it the natural choice where a documented history matters. The 10% assay powder handles applications where a high pigment loading has to fit into a small solids budget.
