Published thresholds

5 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.

Orthonasal, in clean water

50.0 ppb

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

Threshold	Matrix	Source	Paper
50.0 ppb	water_odor	Leffingwell	—
50.0 ppb SIDA	water	Rychlik 1998 · 1 studies	—

In a food matrix

28.0 ppb – 12491 ppb

Measured in a real food, where the matrix shifts detection — not a clean-water value.

Threshold	Matrix	Source	Paper
28.0 ppb	water (food: unknown)	Literature corpus	18941497, 28602301, 31661846
939 ppb	water (food: tea)	Literature corpus	22085842

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 (123.75 ppb, the engine's canonical value — see the 5 published values). OAV ≥ 1 = perceptible.

Food	Concentration (ppb)	OAV	Source
tea	568.0	4.59	Corpus paper
rum	19.4	0.16	Corpus paper

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 share

Every ingredient known to contain anisole. 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 anisole in it. Full concentrations are in the OAV table above.
