ethylphenol

spicy phenol Key food odorant

Found in 1 ingredient across the CompKitchen flavor graph.

Ambiguous name

“ethylphenol” does not identify one molecule. May be 2-, 3- or 4-ethylphenol. The distinction matters in fermented foods: 4-ethylphenol is the Brettanomyces marker, and the others are not.

We assign no CAS number, structure or odour threshold to this entry. Guessing one would make the record look more certain than the evidence is.

Look up another compound — search by name, CAS number, PubChem CID, or FEMA #.

Key food odorant (individualist)

Dunkel et al. 2014

Identified in the meta-analysis of 227 food samples as one of 151 individualist odorants — appears in <5% of foods, carries the diagnostic signature of specific ingredients. Characteristic odor: phenolic, smoky.

Published thresholds

7 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

13.0 ppb – 390 ppb

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

Measured impact first, then profile share

Every ingredient known to contain ethylphenol. 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 ethylphenol in it.
