Natural umami from Saccharomyces cerevisiae. MSG replacement, salt reduction, kokumi mouthfeel, in one SavourOn™ clean-label ingredient.
Herbal Isolates’ Yeast Extract Powder is a SavourOn™ ingredient – produced from Saccharomyces cerevisiae through controlled autolysis, then spray-dried to a free-flowing powder that delivers savoury depth, umami intensity, and mouthfeel enhancement across snacks, soups, sauces, plant-based foods, and processed meat.
The mechanism is straightforward: yeast cells self-digest under controlled conditions, releasing glutamic acid, nucleotides (5′-GMP, 5′-IMP), and peptides that were bound inside the cell. Glutamic acid provides umami. Nucleotides amplify it – the 5′-GMP and 5′-IMP interact synergistically with glutamate to multiply perceived umami intensity by a factor far greater than alone. Peptides contribute kokumi, the ‘mouthfulness’ quality that makes food feel substantial and satisfying.
Our Product Variants
Yeast Extract – Standard (Autolyzed)
Full autolysis of Saccharomyces cerevisiae. Balanced umami and savoury base notes. For soups, seasonings, snacks, sauces, processed meat, and general clean-label savoury applications.
Yeast Extract Powder - High Nucleotide (Umami)
Elevated 5'-GMP and 5'-IMP for maximum umami amplification. Designed specifically for MSG replacement and sodium reduction, nucleotides interact synergistically with glutamate to multiply perceived umami intensity.
Yeast Extract - Kokumi
Enriched gamma-glutamyl peptide profile for mouthfeel and body. Contributes the ‘mouthfulness’ sensation that fat reduction removes from soups, sauces, and dairy alternatives.
Yeast Extract Powder – Debittered
Additional processing removes bitter peptide fractions from standard yeast extract. For mild-flavoured applications, cream soups, premium sauces, light snack seasonings.
Yeast Extract Powder – Reduced Sodium
For formulations targeting sodium reduction on both the seasoning ingredients and the overall nutritional panel. Maintains umami functionality while contributing less sodium per gram of inclusion.
Custom Blend
Yeast extract blended with HVP or other SavourOn™ ingredients to a specific flavour target. For manufacturers who want a single optimized ingredient rather than managing multiple components.

FORMULATION TIP
For a sodium-reduced vegetable broth: replace 30% of added salt with Yeast Extract (0.35%) combined with HVP Powder (0.5%). The nucleotides in yeast extract synergise with glutamates in HVP to multiply perceived umami intensity, meaning the formulation tastes equally flavourful with significantly less sodium — a claim substantiated by multiple double-blind sensory trials.

FAQs
What is yeast extract powder and how is it made?
Yeast Extract Powder is produced from Saccharomyces cerevisiae through autolysis, a controlled process where yeast cells are encouraged to self-digest using their own enzymes. This breaks down proteins into amino acids (including glutamic acid, the umami compound), nucleic acids into nucleotides (5′-GMP and 5′-IMP, which amplify umami), and releases peptides that contribute mouthfeel and B vitamins. The resulting liquid is concentrated and spray-dried to a free-flowing powder. The process uses no chemical hydrolysis unlike HVP, yeast extract is produced entirely through enzymatic and biological breakdown.
2. How is yeast extract different from MSG?
MSG is a purified single compound, isolated glutamate combined with sodium. Yeast Extract Powder is a complex mixture that naturally contains glutamate alongside nucleotides, peptides, amino acids, and B vitamins. Both deliver umami, but yeast extract’s nucleotides synergistically amplify glutamate’s effect, so a small amount achieves equivalent or greater umami than MSG alone. The labeling difference is the commercial driver: MSG must be declared as “monosodium glutamate” or “flavour enhancer (621),” while yeast extract declares as “yeast extract.” For brands positioning as “No Added MSG,” yeast extract fits for “MSG Free,” it does not, since yeast extract naturally contains free glutamate.
3. How does yeast extract help manufacturers reduce sodium in food products?
Yeast extract contains naturally occurring nucleotides, primarily 5′-GMP and 5′-IMP that interact synergistically with glutamate to amplify umami perception. This synergy allows sodium reduction of 20–30% while perceived flavour intensity remains comparable.
4. What is kokumi and how does yeast extract contribute to it?
Kokumi describes “mouthfulness”, the sensation of richness, continuity, and thickness in food that distinguishes a full-bodied soup from a thin one. It is distinct from umami and acts through different receptors (calcium-sensing receptor, CaSR). Gamma-glutamyl peptides naturally present in yeast extract stimulate this receptor. For manufacturers reducing fat in soups, sauces, and dairy alternatives, the Kokumi grade of Yeast Extract Powder partially recovers the mouthfeel that fat removal takes away without adding fat, starch, or artificial texture modifiers.
5. What is the difference between standard yeast extract and high-nucleotide yeast extract?
Standard yeast extract has a balanced profile of glutamate, nucleotides, peptides, and amino acids, suitable as a general-purpose savoury base. High-nucleotide yeast extract is produced to concentrate 5′-GMP and 5′-IMP. These nucleotides deliver disproportionate umami amplification relative to their inclusion level. A small amount creates a large flavour effect when combined with glutamate sources. High-nucleotide grade is used specifically for MSG replacement, salt reduction, and applications where maximum umami per gram of ingredient is the target. It is more expensive per kg but typically effective at half the inclusion of standard grade.
6. Is yeast extract suitable for vegan and plant-based products?
Yes. Yeast is a fungus, not an animal product. This makes yeast extract fully plant-derived and suitable for vegan, vegetarian, and plant-based formulations. No animal allergens apply. Herbal Isolates’ Yeast Extract Powder is Halal and Kosher certified. For vegan meat analogues specifically, yeast extract is one of the most important ingredients: it contributes the savoury depth that plant proteins structurally lack, and it masks the beany off-notes from soy and pea protein that plant-based products struggle with at scale.
7. What are typical dosage levels for Yeast Extract Powder in food applications?
Standard grade in soups, sauces, and seasonings: 0.1–0.5% of finished product. High-nucleotide grade for MSG replacement or salt reduction: 0.05–0.3% alongside glutamate sources. Kokumi grade for mouthfeel in reduced-fat applications: 0.2–0.5%. Processed meat: 0.2–0.4% on finished weight. Snack coating seasonings: 0.2–0.5% of blend. Instant noodle sachets: 0.3–0.5% of dry mix. These are starting points. Yeast extract works synergistically with HVP, nucleotides, and salt, so the presence of other umami sources in your formula affects how much is needed.
8. Does yeast extract cause the same consumer concerns as MSG?
Some consumers who report sensitivity to MSG express similar concerns about yeast extract, since both contain glutamate. Scientific consensus does not support “MSG sensitivity” as a clinically validated condition, and the glutamate in yeast extract at typical food inclusion rates (0.1–0.5%) is far lower than in standard MSG usage. From a labeling perspective, the two are distinct: yeast extract is a natural fermentation product with multiple functional components; MSG is a purified chemical salt. For brands navigating consumer perception, “No Added MSG” is the relevant claim, which yeast extract supports. “MSG Free” is not accurate, since yeast extract naturally contains free glutamate.
