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

12.0 ppb

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

Threshold	Matrix	Source	Paper
12.0 ppb	water_odor	Leffingwell	—

In a food matrix

1.1 ppb – 230 ppb

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

Threshold	Matrix	Source	Paper
1.1 ppb	water (food: reference standard (water))	Literature corpus	—
230 ppb	water (food: litsea pungens fruit)	Literature corpus	—

Retronasal / in-mouth

0.260 ppb

Tasted rather than smelled — a different sense, not comparable.

Other matrix

84.0 ppb

Measured in a non-aqueous medium (oil, starch, cellulose).

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.

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 cineole. 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 cineole in it.
