Glutathione Yeast for Plant-Based Meat

ART-NY-052 is an inactive glutathione yeast produced for food manufacturers that need a dry, yeast-derived source of glutathione in plant-based meat systems. The ingredient is not a live leavening yeast and is not intended to ferment dough or beverage substrates. Instead, it contributes a nutritional yeast matrix containing protein, peptides, nucleotides, minerals, and a specified glutathione fraction. Typical commercial targets may include total glutathione adjusted by lot, often in the range of 0.5–2.0%, with moisture not more than 6.0%, protein commonly 40–50% on a dry basis, ash commonly below 8.0%, and a fine powder particle size such as 80 mesh or comparable sieve profile.

In plant-based meat, glutathione yeast is used where formulators want a clean-label-compatible yeast ingredient that can be dispersed into pea, soy, wheat, mycoprotein, or blended protein matrices. The sulfur-containing tripeptide fraction can support savory flavor development during heating and can be evaluated alongside yeast extract, hydrolyzed vegetable protein, natural flavors, fats, and color systems. For related yeast ingredients, see our nutritional yeast category. Final performance should be confirmed in the customer’s recipe, extrusion condition, retort cycle, or thermal process.

• Plant-based meat patties, grounds, and crumbles: dry blend with texturized vegetable protein, methylcellulose, starches, fibers, and seasoning systems before hydration and forming.
• High-moisture extrusion: trial in the dry premix phase to assess dispersion, flavor contribution, and processing tolerance under barrel temperature and shear conditions.
• Vegan sausage, nuggets, and ready meals: use as a yeast-derived glutathione source in savory systems requiring consistent powder handling and batch documentation.
• Flavor and seasoning premixes: combine with salt, yeast extract, spice oleoresins, amino acid blends, and reducing sugars where the formulation is designed for cooked savory notes.
• Nutrition-forward dry blends: evaluate in vegan powders and food supplement formats where inactive yeast protein, peptides, and glutathione content are specified by lot; no health or clinical claims are implied.

Suggested use levels depend on glutathione assay, target flavor impact, label strategy, and heat process. ArtemisYeast can support industrial buyers with specification review and a bulk quote on request for pilot, pallet, or container requirements.

Store ART-NY-052 in the original sealed 10 kg foil-lined sack in a cool, dry, odor-free warehouse. Recommended storage is below 25°C, protected from direct sunlight, steam, condensation, and strong-smelling materials. Keep the bag closed after partial use and transfer only with clean, dry equipment. Under recommended storage conditions, typical shelf life is 18–24 months from manufacture, subject to the confirmed certificate of analysis and purchase order terms.

The powder is designed for dry blending and should be introduced where adequate mixing energy is available to avoid localized concentration. Because it is an inactive yeast ingredient, it should not be specified where viable yeast activity, gas production, or fermentation kinetics are required.

Each shipment can be supplied with a lot-specific certificate of analysis covering appearance, odor, moisture, protein or nitrogen-based assay where applicable, glutathione assay, microbiological limits, and heavy metal screening according to the agreed specification. Typical microbiological controls include total plate count, yeast and mold, coliforms, and absence testing for major foodborne pathogens as required by the destination market and application.

Manufacturing documentation may include HACCP-aligned process controls, allergen statement, non-GMO statement where supported by the supply lot, food-grade declaration, Halal or Kosher documentation where available, and ISO 22000 or FSSC 22000 documentation where available from the producing site. ArtemisYeast does not represent this SKU as certified organic unless that status is confirmed in writing for the quoted lot.
