Published thresholds

8 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

37.7 ppb – 828 ppb

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

Threshold	Matrix	Source	Paper
0.120 ppb	water (food: fish)	Literature corpus	41183907
Flagged: 882× from the median of this group. Excluded from the range above pending re-check against the source publication — shown rather than hidden.

828 ppb	water (food: olive oil)	Literature corpus	28671107

In air

1700 ppb – 3935 ppb

Airborne detection — not comparable to a water threshold.

Measured impact first, then profile share

Every ingredient known to contain acetic acid methyl ester. 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 acetic acid methyl ester in it.
