Key food odorant (generalist)
Dunkel et al. 2014Identified in the meta-analysis of 227 food samples as one of 16 generalist odorants — appears in >25% of foods, typically from generic Maillard, lipid-oxidation, or fermentation pathways. Characteristic odor: vinegar-like.

Published thresholds
43 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
36000 ppbThe reference measurement — smelled in water. OAV is computed against this.

Measured impact first, then profile shareEvery ingredient known to contain ethanoic acid. 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 ethanoic acid in it.
Get a molecule-level pairing breakdown each week — which ingredients share a compound, and why it matters at the table. Free, no spam.
