Feed-Grade Yeast Extract

ART-AN-025 feed-grade yeast extract is produced from inactive yeast biomass through controlled autolysis or hydrolysis, followed by separation and drying into a free-flowing powder. The resulting ingredient contains water-soluble yeast solids, including short-chain peptides, free amino acids, B-complex-associated yeast nutrients, nucleotides, organic nitrogen and fermentation-derived flavor compounds. It is designed for feed applications where formulators need a non-live yeast fraction with high solubility, consistent sensory contribution and reliable handling in industrial batching systems.

Typical specification targets may include crude protein 40-55%, moisture not more than 6-8%, ash 8-15%, total nitrogen declared on CoA, and particle size commonly passing 40-80 mesh depending on production lot and customer requirement. As a non-viable yeast derivative, it is not specified by CFU/g; buyers requiring live yeast should review relevant products in animal nutrition yeast. ART-AN-025 is intended for use as a feed material or palatability-supporting component in balanced diets, premixes and specialty feed blends, subject to local feed regulations and the customer’s label requirements.

• Livestock and swine feed: Used in complete feed, starter feed, creep feed and specialty premixes where soluble yeast peptides and amino acids can support formulation flexibility and feed acceptance.
• Poultry nutrition: Suitable for broiler, layer and breeder feed systems as a yeast-derived protein and flavor fraction, especially in mash, crumble and pellet programs requiring uniform powder dispersion.
• Ruminant feed: Can be incorporated into dairy and beef premixes, mineral blends and concentrates where formulators specify inactive yeast extract rather than live yeast culture.
• Aquaculture feed: Used in fish and shrimp feed formulas as a soluble yeast-based attractant and nitrogen source; confirm inclusion rate, water stability and pellet process compatibility during R&D trials.
• Pet and specialty feed manufacturing: Applicable in dry blends and extruded feed where a savory yeast profile and clean ingredient declaration are desired.

Inclusion levels vary by species, feed format and target label positioning. Common trial ranges are 0.2-2.0% in complete feed, or higher in concentrates and premixes when diluted into final feed. ArtemisYeast can support technical review for mills comparing yeast extract with inactive yeast, yeast cell wall, autolyzed yeast and hydrolyzed yeast fractions before submitting a bulk quote on request.

Store ART-AN-025 in the original sealed 25 kg woven polypropylene feed sack in a cool, dry, ventilated warehouse. Recommended storage is below 25 °C with relative humidity controlled to reduce caking risk. Keep away from direct sunlight, condensation, strong odors and pest exposure. Under recommended storage conditions, typical shelf life is 18-24 months from production date, subject to the specific lot CoA and packaging configuration.

Yeast extract is hygroscopic because of its soluble solids content. After opening, reseal bags promptly or transfer to closed food/feed-compatible bins. In automated dosing systems, validate flowability with the customer’s screw feeder, loss-in-weight feeder or micro-ingredient system. The product can be blended into premixes, top-dressed applications or base feed before pelleting or extrusion; however, thermal process validation remains the responsibility of the feed manufacturer. Use standard dust-control procedures, local exhaust where needed and appropriate personal protective equipment when charging mixers or bag dump stations.

ArtemisYeast supplies ART-AN-025 for professional feed and animal nutrition manufacturing under lot-controlled production and export-oriented documentation practices. A typical release package can include certificate of analysis, product specification, safety data sheet, feed-grade declaration, origin statement, allergen statement where applicable and non-GMO status statement when supported by the production lot. HACCP-aligned manufacturing information, ISO 22000, FSSC 22000, Halal or Kosher documentation may be available on request depending on the supplying facility and batch. Review available documents through quality and documentation before purchase approval.

Routine quality checks may cover appearance, odor, moisture, crude protein, ash, pH in solution, particle size, microbiological limits and heavy metals according to the agreed specification. Typical microbiological limits for feed-grade yeast extract may include total plate count, yeast and mold, coliforms and absence of selected pathogens in the tested sample size, as stated on the CoA. For procurement qualification, ArtemisYeast can discuss target specification ranges, private-label packaging needs, palletization, container loading, multilingual documents and destination-market feed compliance expectations. Wholesale pricing on request is provided after confirming annual volume, destination port, documentation scope and required incoterms.
