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.

In a food matrix

1.4 ppb – 24.5 ppb

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

Threshold	Matrix	Source	Paper
1.4 ppb	water (food: apple)	Literature corpus	37021304
5.0 ppb	water (food: rice)	Literature corpus	38846797, 40467248
24.5 ppb	water (food: unknown)	Literature corpus	25717332

In air

10.0 ppb

Airborne detection — not comparable to a water threshold.

Measured impact first, then profile share

Every ingredient known to contain hexyl caproate. 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 hexyl caproate in it.
