Published thresholds

6 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

11.0 ppb – 21.0 ppb

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

In a food matrix

1.1 ppb – 35.0 ppb

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

Retronasal / in-mouth

88.0 ppb

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