Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool. Odor threshold ...

The recognition odor threshold is usually a factor of two to five higher than the detection threshold. [22] The measurement of odor concentration is the most widespread method to quantify odors. It is standardized in CEN EN 13725:2003. [23] The method is based on dilution of an odor sample to the odor threshold. The numerical value of the odor ...
Oct-1-en-3-one has a strong metallic mushroom-like odor with an odor detection threshold of 0.03–1.12 μg/m 3 and it is the main compound responsible for the "smell of metal", followed by decanal (smell: orange skin, flowery) and nonanal (smell: tallowy, fruity). [3]
