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

4 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

3.4 ppb – 190 ppb

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

Threshold	Matrix	Source	Paper
0.002 ppb	water (food: olive oil)	Literature corpus	41023141
Flagged: 3560× from the median of this group. Excluded from the range above pending re-check against the source publication — shown rather than hidden.
3.4 ppb	water (food: tea)	Literature corpus	36540235, 40226889
10.8 ppb	water (food: unknown)	Literature corpus	20730965, 38316894, 39931095 +2
190 ppb	water (food: fish)	Literature corpus	40351771

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.

Where you'd actually smell it

Odor Activity Value = measured concentration ÷ odor threshold (7.12 ppb, the engine's canonical value — see the 4 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile share

Every ingredient known to contain luteolin. 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 luteolin in it. Full concentrations are in the OAV table above.
