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 ppb

The reference measurement — smelled in water. OAV is computed against this.

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).

Thresholds in published tables

Numbers printed in open-access papers, grouped by the medium the table states. Median and full range of the values; “agree” means two or more papers whose middle 80% of values sit within 100×. Not reviewed.

Measured impact first, then profile share

Every 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.
