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

6.1 ppb

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

In a food matrix

0.500 ppb – 246 ppb

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

Retronasal / in-mouth

15.0 ppb – 30.0 ppb

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

Measured impact first, then profile share

Every ingredient known to contain dimethyl disulphide. 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 dimethyl disulphide in it.
