Key food odorant (intermediary)

Dunkel et al. 2014

Identified in the meta-analysis of 227 food samples as one of 57 intermediary odorants — appears in 5–25% of foods. Characteristic odor: smoky, clove-like.

Published thresholds

12 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

3.0 ppb – 60.0 ppb

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

5.0 ppb SIDA	water	Dunkel 2014	—
60.0 ppb SIDA	water	Rychlik 1998 · 2 studies	—

In a food matrix

5.0 ppb – 30.0 ppb

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

Retronasal / in-mouth

4.0 ppb

Tasted rather than smelled — a different sense, not comparable.

Other matrix

18.3 ppb – 1042 ppb

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

Measured impact first, then profile share

Every ingredient known to contain 4-ethenyl-2-methoxyphenol. 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 4-ethenyl-2-methoxyphenol in it.
