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

3.0 ppb

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

Threshold	Matrix	Source	Paper
3.0 ppb	water_odor	Leffingwell	—

In a food matrix

425 ppb

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

Threshold	Matrix	Source	Paper
425 ppb	water (food: reference standard (water))	Literature corpus	—

Retronasal / in-mouth

31.0 ppb

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

31.0 ppb	water_flavor	Leffingwell	—

In air

4.8 ppb – 100 ppb

Airborne detection — not comparable to a water threshold.

4.8 ppb	air	Nagata 2003	—
100 ppb	air (C1_cometto_muniz_cain)	Cometto-Muñiz (PMC)	—

Other matrix

20.0 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 n-heptanol. 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 n-heptanol in it.
