Published thresholds
1 measured value 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.
Orthonasal, in clean water
100 ppbThe reference measurement — smelled in water. OAV is computed against this.
| Threshold | Matrix | Source | Paper |

| 100 ppb | water_odor | Leffingwell | — |
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 (100.0 ppb, the engine's canonical value — see the 1 published values). OAV ≥ 1 = perceptible.
| Food | Concentration (ppb) | OAV | Source |

| yugu melon | 123900.0 | 1239 ⚡ | — |
| french vanilla e-liquid | 8400.0 | 84.0 ⚡ | — |
Concentrations from PubMed Central Open Access papers (free literature corpus, MIT-style licensed). Copper = OAV ≥ 10 (strongly perceptible). Green = OAV ≥ 1 (perceptible).

Measured impact first, then profile shareEvery ingredient known to contain ethyl vanillin. 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 ethyl vanillin in it. Full concentrations are in the OAV table above.
