A yeast protein concentrate from Saccharomyces cerevisiae with at least 80.0% protein on a dry basis and 75.0% as is. The cultured yeast is treated with glucanase and protease, sterilised above 110 C and spray-dried into a pale yellow powder with a characteristic yeast odour. Supplied with the producer's specification, raw material survey, process flow chart and SDS.
Tell us what you are developing and which documents you need. We reply from Japan within one working day with the product specification, SDS and the CoA of the current lot.
The producer's process flow chart runs from yeast culture to a sieved, metal-checked powder. The yeast is cultured on a molasses-based medium, separated, and taken through two enzyme stages, glucanase and protease, before high-temperature sterilisation and spray-drying.
Step 1 · Saccharomyces cerevisiae
Medium: molasses, aqueous ammonia, ammonium dihydrogen phosphate
Step 2 · separation
The yeast cells are separated from the culture
Step 3 · glucanase
Glucanase acts on the glucan of the yeast cell wall
Step 4 · centrifuge
Separation step between the two enzyme stages
Step 5 · protease
Second enzyme stage
Step 6 · above 110 C
High-temperature sterilisation, then spray-drying to powder
Step 7 · 0.6 mm aperture
Then 13 magnet bars at 9,000 gauss
Step 8 · iron 1.5 mm
Metal detection after packing: iron 1.5 mm, stainless steel and non-ferrous 2.0 mm

If you are comparing ingredients for a new SKU, these questions separate one material from another quickly.
This powder is produced in China and shipped by us from Japan. Build your origin wording on that fact; if a Japan-processed form matters to your brand, ask for the granulated grade.
The specification guarantees min. 80.0% on a dry basis and min. 75.0% as is. Nutrition panels are calculated on the product as sold, so plan with the as-is value or the result for your lot.
The raw material survey lists no animal-derived materials, but no halal, kosher or vegan certificate is in our document set for this product. In the UAE, supplements need a halal certificate.
The specification describes a characteristic yeast odour. Taste it in your actual base and flavour system before you scale the formula.
The SDS advises checking for discolouration and sedimentation when the powder is combined with other ingredients. Run it with your minerals, acids and flavours.
Besides this 80% powder, a 90% grade and a granulated grade are available. Tell us your format and protein target and we send the matching document set.

Yeast Protein 80% is a protein concentrate made from Saccharomyces cerevisiae, the species known as baker's yeast. It is not whole dried yeast. The cultured yeast goes through two enzyme stages, glucanase and protease, with centrifugation in between; the finished powder is specified at min. 80.0% protein on a dry basis and min. 75.0% as is.
It is a non-animal protein. The producer's raw material survey lists 100% yeast protein concentrate, no food additives and no allergen subject to mandatory labelling in Japan, which makes it a candidate for formulas built outside the dairy and soy supply chains.
This page describes the 80% powder. A 90% grade (min. 90.0% protein dry basis, min. 84.0% as is, moisture max. 6.0%, ash max. 6.0%) and a granulated grade processed in Japan are supplied on request.
If you want a finished product rather than the raw material, our plant in Gunma, Japan fills sticks and aluminium pouches. Send your formula and target pack for an OEM quotation. For minerals in the same formula, see our sesame mineral powder; for a marine protein with a different amino acid pattern, see Fish Collagen Tripeptide.
Saccharomyces cerevisiae, the species behind baker's and brewer's yeast, is a single-celled fungus. A yeast protein concentrate takes the protein of that cell and leaves much of the rest behind. For a formulator it is a third route to protein, next to animal sources such as milk and egg and plant sources such as soy, pea and rice.
The yeast cell is wrapped in a wall built largely from glucans and mannans. Dried whole yeast keeps that wall together with the protein, the nucleic acids and the rest of the cell. A concentrate is processed to raise the protein share: in this product, glucanase acts on the cell-wall glucan, centrifugation separates the fractions and a protease stage follows before sterilisation and spray-drying. The result is specified by its protein content, not as whole yeast.
Protein quality describes how well a protein's indispensable (essential) amino acids match human requirements and how well they are digested. A common reference pattern comes from the 2007 joint FAO/WHO/UNU expert report on protein and amino acid requirements (WHO Technical Report Series 935).
Two recent protein-quality studies used yeast protein from Saccharomyces cerevisiae. They describe the ingredient class, not a specific lot; the lot you buy is defined by its specification.
Yeast protein was compared with whey protein concentrate and isolate and with soy, wheat and pea proteins. It had the highest ratio of indispensable to dispensable amino acids of the proteins tested (0.91). Its true protein digestibility was lower than that of the other proteins, in vivo and in vitro. For the over-3-years reference group the authors report an amino acid score of 1.37, a PDCAAS of 100% and a DIAAS of 82.42%: above the plant proteins and below the animal proteins, mainly because of the lower digestibility. doi:10.1016/j.foodchem.2024.141178
Yeast protein combined with whey or soy protein isolate gave body weight gains comparable to casein. Tryptophan had the highest true ileal digestibility of the amino acids in yeast protein, 99.92%. Mixing yeast protein with soy or whey isolate at optimised ratios raised true digestibility, and blends improved DIAAS values. doi:10.1021/acs.jafc.5c06807
The producer's raw material survey lists molasses, aqueous ammonia and ammonium dihydrogen phosphate as culture medium components. Molasses is a by-product of sugar production from cane or beet; ammonia and phosphate supply the nitrogen and phosphorus the yeast needs to grow.

Iizuka Shoukai, a trading company in Gunma, Japan, supplies it with the producer's specification, raw material survey, process flow chart and SDS, and ships from Japan 1-1.5 weeks after payment. A granulated grade processed in Japan is available on request.
At least 80.0% protein on a dry basis and at least 75.0% as is, both by the Kjeldahl method, with moisture not more than 8.0% and ash not more than 5.0%. Lead is limited to 2.0 ppm, arsenic to 1.0 ppm and total plate count to 3,000 CFU/g. A 90% grade (at least 90.0% dry basis, 84.0% as is) is available on request.
The minimum order is 25 kg, one producer bag, at 22 USD/kg, and registered companies can request a free 100 g evaluation sample. Payment is 100% prepayment by SWIFT or Stripe. Freight is quoted on request, and larger orders are quoted by volume. The producer packs the powder in 25 kg kraft paper bags with an inner polyethylene bag.
The producer's raw material survey lists 100% yeast protein concentrate from Saccharomyces cerevisiae, no food additives, no animal-derived raw materials and no allergen subject to mandatory labelling in Japan; pesticides and antibiotics are not used. Halal, kosher and vegan certificates are not in our document set for this product, so check what your market and claims require before launch.
