Yeast extract 酵母エキス
Food ingredientUsed in 23 products on this site
Yeast extract is made by breaking down the contents of yeast (the microorganism used to make bread and beer) with the yeast's own enzymes or added enzymes, and then taking out the broken-down material. It contains umami components such as amino acids and nucleic acids, and is used to add umami to soups, roux, and seasonings.
How it appears on labels
| On the label (Japanese) | Meaning |
|---|---|
| 酵母エキス | yeast extract |
| 酵母エキス（小麦を含む） | yeast extract (contains wheat) |
Labeling rules
- On Japanese food labels, it is treated as a food ingredient, not a food additive. It is written before the slash (／) in the ingredient list, in the food ingredient section, in descending order by weight.
- The Consumer Affairs Agency's Q&A on the Food Labeling Standards gives “酵母エキス（小麦を含む）” (yeast extract (contains wheat)) as an example of allergen labeling. Yeast extract that contains wheat is written this way.
- The guideline on labeling of extracts (“エキスの表示に関するガイドライン”, 2023) by the Japan Extract Seasoning Association defines an extract as something made from raw materials such as agricultural, marine, or livestock products, or yeast, by extraction, autolysis, enzyme treatment, and similar methods, to add flavor to food. It lists yeast extract as one of these.
Good to know
- It is a different thing from the food additive “調味料（アミノ酸等）” (seasoning (amino acids, etc.)). “調味料（アミノ酸等）” refers to food additives in which each component, such as monosodium glutamate, is taken out and used on its own.
- The Consumer Affairs Agency's “Guideline on labeling of food additive-free claims” (2022) gives, as an example of a label that may mislead (type 5: claims on foods that use ingredients with the same or similar function), a claim of “調味料不使用” (no seasoning used) on a product that uses an extract containing amino acids.
- Among the products on this site, it is in curry roux and oyster sauce.
