Definition and Description
An odor unit is a numerical value representing the point at which a panel of assessors detects an odor in a substance. It is determined by presenting the substance in decreasing dilution (increasing concentration) until the panel can detect the odor, which is known as the detection threshold (DT). In this context, 1 Odor Unit is the minimal concentration at which the odor becomes perceptible. Odor units are used to quantify and describe the strength or intensity of odors.
