How this molecule is described
Sources disagree about odour more often than they disagree about chemistry. Rather than show one answer, here is every description on file with how many ingredient records carry it.
Ordered by how many independent descriptor streams give each wording, then by how often it appears. The bar is still replication — one source copied onto many ingredients scores high there — so the two can disagree.
Bars are the share of ingredient records carrying each description. High agreement means the sources replicate each other — not necessarily that they are right.
Published thresholds
3 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.
In a food matrix
0.0001 ppb – 0.002 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.
| Threshold | Matrix | Source | Paper |
|---|---|---|---|
| 0.0001 ppb | water (food: hand-squeezed grapefruit juice) | Literature corpus | — |
| 0.002 ppb | water (food: green tea infusion (jingshan cha)) | Literature corpus | — |
| 0.002 ppb | water (food: longjing green tea infusion) | Literature corpus | — |
Only values we can attribute are listed. Where a compendium's licence does not permit public attribution its figures are omitted here, so every number on this page traces to a citable source.
Where you'd actually smell it
Odor Activity Value = measured concentration ÷ odor threshold (0.0016 ppb, the engine's canonical value — see the 3 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile shareEvery ingredient known to contain 3-furanthiol. 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-furanthiol in it. Full concentrations are in the OAV table above.
