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

10 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

7820 ppb – 9000 ppb

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

In a food matrix

0.160 ppb – 24.0 ppb

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

In air

94.0 ppb – 14125 ppb

Airborne detection — not comparable to a water threshold.

Measured impact first, then profile share

Every ingredient known to contain n-propanol. 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-propanol in it.
