How this molecule is described

  • sulfur shown above Flavornet Cas
  • roasted, coffee, fishy FlavorDB 2.0, Flavordb Odor Column 2 sources agree

Ordered by how many independent descriptor streams give each wording, then by how often it appears. The bar is replication (one source copied onto many ingredients scores high), not corroboration.

Which foods contain 2-thiophenemethanol?

We list 3 ingredients that contain it, but presence is not the same as smell. What matters is how much is there compared with how little it takes to notice it. That ratio is the odour activity value (OAV): above 1, you can smell it.

Found in

Measured foods first, then real food profiles, then thin or composite records (marked). The figure beside each is how many compounds that ingredient has in total, not the amount of 2-thiophenemethanol in it. ✓n = sources that recorded the link.

How strong is 2-thiophenemethanol?

Our working odour threshold is 0.0075 ppb.
