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

240 ppb

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

Threshold	Matrix	Source	Paper
240 ppb	water	PMC open access	—

In a food matrix

0.740 ppb – 1.2 ppb

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

Threshold	Matrix	Source	Paper
0.740 ppb	water (food: fish)	Literature corpus	41183907
1.2 ppb	water (food: unknown)	Literature corpus	25482491, 26666273, 27347408 +3
483 ppb	water (food: tea)	Literature corpus	31861730, 36540235
Flagged: 390× from the median of this group. Excluded from the range above pending re-check against the source publication — shown rather than hidden.

In air

120 ppb

Airborne detection — not comparable to a water threshold.

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

Food	Concentration (ppb)	OAV	Source
tea	487.0	2.03	—
fish	280.0	1.17	—

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 cyclohexanone. 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 cyclohexanone in it. Full concentrations are in the OAV table above.
