Selenium Enriched Yeast Protein
Selenium Enriched Yeast Protein is a protein concentrate isolated from Saccharomyces cerevisiae grown on a selenium supplemented medium.
During growth the yeast incorporates inorganic selenium into amino acids, primarily as selenomethionine, which is then carried into the cellular protein fraction. The isolated protein delivers selenium in its most bioavailable organic form.
We source bulk Selenium Enriched Yeast Protein from top China manufacturers for our partners. The manufacturer is in Guangdong. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Selenium Enriched Yeast Protein comes in nutritional supplement and functional food grades.
The principal specification controls total selenium content, the proportion present as selenomethionine, total protein content, and the level of any residual inorganic selenium.
Typical commercial grades carry total selenium between 1000 and 3000 parts per million on the dry basis, with selenomethionine representing more than 60 percent of the total selenium.
Protein content is usually above 60 percent. The product is a fine cream coloured powder for direct blending into tablets, capsules, and functional beverage powders.

How We Help Source Selenium Enriched Yeast Protein
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Selenium Enriched Yeast Protein out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Selenium Enriched Yeast Protein together with other ingredients such as Sodium Acid Pyrophosphate, Monocalcium Phosphate and Diammonium Phosphate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Selenium yeast and selenium yeast protein products are well established in the nutritional supplement market.
In the European Union selenium-enriched yeast inactivated is authorised as a source of selenium in food supplements and is listed in regulation 1170/2009.
The U.S. Food and Drug Administration recognises high selenium yeast as a GRAS source of selenium for nutritional purposes, with controls on total selenium content and the proportion present in organic form.
JECFA has reviewed selenium yeast and recognised its value as a bioavailable selenium source. Specifications appear in the FCC and in the EU additive monograph collection.
Manufacturing Process
Selenium Enriched Yeast Protein production begins with controlled fed batch fermentation of Saccharomyces cerevisiae in a defined molasses and mineral medium.
During the growth phase, sodium selenite is dosed into the broth at carefully controlled concentrations. The yeast metabolism reroutes part of its sulphur amino acid biosynthesis to incorporate selenium, producing selenomethionine in place of methionine in newly synthesised proteins.
At the end of fermentation the cells are washed to remove residual inorganic selenium and unincorporated selenocompounds. The biomass is then mechanically disrupted, and the protein fraction is recovered by selective extraction and isoelectric precipitation.
The isolated protein is washed, neutralised, spray dried, and milled. Strict analytical controls confirm total selenium, selenomethionine fraction, and the absence of residual inorganic selenium.
