Yeast Peptides
Yeast Peptides are short chain protein fragments produced by controlled enzymatic hydrolysis of Saccharomyces cerevisiae protein.
The resulting ingredient is a mixture of free amino acids and peptides with molecular weights typically below 5000 daltons. The low molecular weight gives high solubility, rapid digestion, and a clean savory umami flavour.
We source bulk Yeast Peptides from top China manufacturers for our partners. The manufacturer is in Hebei. 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
Yeast Peptides come in two grades, nutritional and flavour.
Nutritional grade is characterised by protein content above 70 percent, a high free amino acid fraction, and a defined molecular weight distribution. It is a light yellow free flowing powder.
Flavour grade is processed to maximise umami intensity. The hydrolysis conditions favor the release of glutamic acid and savory peptides, giving a more pronounced taste impact at lower dose.
Both grades are spray dried from concentrated hydrolysate and offered in standard bag and bulk container formats.
Applications
- Sports nutrition and recovery drinks seeking rapidly absorbed nitrogen

China Manufacturers of Yeast Peptides

How We Help Source Yeast Peptides
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 Yeast Peptides 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 Yeast Peptides 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
Yeast Peptides are treated as ordinary food ingredients in most major regions.
The parent yeast biomass and its hydrolysate are recognised food materials under the food regulations of the European Union, the United States, China, Japan, and other major markets.
Hydrolysed yeast and yeast extracts are listed in the EU food category system. The U.S. Food and Drug Administration permits autolyzed yeast and yeast extract as flavour ingredients with appropriate identity declarations.
Allergen labelling rules vary by jurisdiction but yeast peptides from Saccharomyces cerevisiae are not generally considered priority allergens. Halal and Kosher certifications are commonly available.
Manufacturing Process
Yeast Peptides are produced by enzymatic hydrolysis of yeast protein.
The starting material is concentrated yeast protein, typically obtained from autolyzed and washed Saccharomyces cerevisiae biomass. The protein is suspended in water and treated with a sequence of food grade proteases such as endopeptidases and exopeptidases.
The enzyme cocktail and hydrolysis conditions are tuned to deliver the target molecular weight distribution and flavour profile. The reaction proceeds for several hours at controlled pH and temperature.
At the end of hydrolysis the enzymes are inactivated by a brief heat treatment. The hydrolysate is filtered to remove insolubles, concentrated by evaporation, and spray dried to a free flowing powder.
