Key food odorant (intermediary)

Dunkel et al. 2014

Identified in the meta-analysis of 227 food samples as one of 57 intermediary odorants — appears in 5–25% of foods.

Not in FEMA GRAS publications 1-33. Of 3,367 listed flavoring substances, none match this compound name. May still be food-safe under other regulatory routes (FDA 21 CFR 172, EFSA, JECFA) — check femaflavor.org for the authoritative current list.

Published thresholds

6 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

11.0 ppb – 21.0 ppb

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

Threshold	Matrix	Source	Paper
11.0 ppb	water_odor	Leffingwell	—
21.0 ppb	water/ethanol 6:4 (food: american bourbon whisky)	Literature corpus	—

In a food matrix

1.1 ppb – 35.0 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	—
23.0 ppb	water (food: unknown)	Literature corpus	—
35.0 ppb	water (food: chocolate)	Literature corpus	—

Retronasal / in-mouth

88.0 ppb

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

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.

Measured impact first, then profile share

Every ingredient known to contain gamma-decanolactone. 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 gamma-decanolactone in it.
