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 air

2.1 ppb

Airborne detection — not comparable to a water threshold.

Measured impact first, then profile share

Every ingredient known to contain 5-methyl-2-hexanone. 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 5-methyl-2-hexanone in it.
