About
Yeast extract is a natural flavoring ingredient derived primarily from Saccharomyces cerevisiae yeast by autolysis or enzymatic hydrolysis; it is rich in free amino acids (especially glutamate), nucleotides, and B vitamins, and is widely used to impart savory, umami taste in soups, sauces, snacks, and processed foods. Unlike isolated MSG, its glutamate is delivered within a complex matrix of proteins, peptides, and nucleotides.
Safety summary
Yeast extract is broadly recognized as safe, holds GRAS status in the US under 21 CFR 184.1983, and its source organism Saccharomyces cerevisiae is listed under EFSA's Qualified Presumption of Safety (QPS) approach; no ADI has been formally established because it is treated as a food ingredient rather than a regulated additive. The high free-glutamate content may provoke symptoms in glutamate-sensitive individuals and migraine sufferers, while a significant purine load can elevate uric acid and exacerbate gout; many commercial preparations also carry substantial sodium levels, warranting caution for hypertensive consumers. IARC has not classified yeast extract as a carcinogen.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Yeast extract is permitted as a food ingredient under the Australia New Zealand Food Standards Code; it is not assigned a food additive code and must be declared by name on labels. No maximum use level is specified; GMP applies.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Yeast extract is not classified as a food additive under Regulation (EC) No 1333/2008 and carries no E-number; it is used as a food ingredient or flavoring. Saccharomyces cerevisiae (the production organism) is confirmed suitable for EFSA's Qualified Presumption of Safety (QPS) approach. EU labelling law requires it to be declared as 'yeast extract' on ingredient lists.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Baker's Yeast and its derivatives (including yeast extract) are regulated under FSS (Food Products Standards and Food Additives) Second Amendment Regulation, 2017, which prescribed compositional and quality standards for Baker's Yeast; yeast extract is permissible as a food ingredient under the general provisions of FSS (Food Products Standards and Food Additives) Regulations, 2011.source |
| FDA (Food and Drug Administration) (United States) | Approved | Baker's Yeast Extract is listed as GRAS under 21 CFR 184.1983 for use as a flavoring agent and flavor enhancer at GMP levels; FDA requires it to be declared as 'yeast extract' on ingredient labels, distinct from monosodium glutamate. |
