How this molecule is described

Sources disagree about odour more often than they disagree about chemistry. Rather than show one answer, here is every description on file with how many ingredient records carry it.

Descriptions on file

Ordered by how many independent descriptor streams give each wording, then by how often it appears. The bar is still replication — one source copied onto many ingredients scores high there — so the two can disagree.

Bars are the share of ingredient records carrying each description. High agreement means the sources replicate each other — not necessarily that they are right.

Published thresholds

5 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

0.006 ppb

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

Threshold	Matrix	Source	Paper
0.006 ppb SIDA	water	Rychlik 1998 · 1 studies	—

Other matrix

0.130 ppb – 0.220 ppb

Measured in a non-aqueous medium (oil, starch, cellulose).

Threshold	Matrix	Source	Paper
0.130 ppb	wine matrix (12% ethanol) (food: rum / red wine)	Literature corpus	—
0.220 ppb	ethanol/water (food: rum / red wine)	Literature corpus	—
0.220 ppb	ethanol/water 40/60 (food: rum (aged))	Literature corpus	—
0.220 ppb	ethanol/water 40/60 (food: rum (young))	Literature corpus	—

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.

Measured impact first, then profile share

Every ingredient known to contain ethyl (2s)-2-methylbutanoate. 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 ethyl (2s)-2-methylbutanoate in it.
