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.

Orthonasal, in clean water

180 ppb

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

Measured impact first, then profile share

Every ingredient known to contain methyl 3-(methylthio)propanoate. 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 methyl 3-(methylthio)propanoate in it.
