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.

Retronasal / in-mouth

10.0 ppb

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

Measured impact first, then profile share

Every ingredient known to contain 3,5-dimethyl-1,2,4-trithiolane. 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 3,5-dimethyl-1,2,4-trithiolane in it.
