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.

Also filed as

e-2-undecen-1-ol

Same molecule, unified here — previously counted and displayed as separate compounds.

Published thresholds

1 measured value 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

1715 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 trans-2-undecen-1-ol. 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 trans-2-undecen-1-ol in it.
