3 measured values from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.
In a food matrix
4.0 ppb – 22.0 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.
| Threshold | Matrix | Source | Paper |
|---|---|---|---|
| 4.0 ppb | water (food: beer) | Literature corpus | 41730959 |
| 4.8 ppb | water (food: tomato) | Literature corpus | 38253713 |

Only values we can attribute are listed. Where a compendium's licence does not permit public attribution its figures are omitted here, so every number on this page traces to a citable source.
Where you'd actually smell it
Odor Activity Value = measured concentration ÷ odor threshold (4.85 ppb, the engine's canonical value — see the 3 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile shareEvery ingredient known to contain daidzein. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of daidzein in it. Full concentrations are in the OAV table above.
