Odour Activity Value (OAV) is often used to know the ‘weight’ of perception of an odorant . This is calculated from the abundance of that odorant molecule divided by the odour detection threshold, or Odour Threshold Value (OTV).
The odour detection threshold is understood to be the lowest concentration of a certain odor compound that is perceivable by the human sense of smell.
In practical terms this is a very variable value, because human olfactive sensitivity varies over a wide range. This uncertainty has been removed by making OTV’s traceable to an agreed reference stimulus, in the EN13725:2003 European olfactometry standard.
The Sensenet Labs offers this free webinar, which explains in detail the procedure for calculating the OTV value according to the European standard EN13725.
Who is it for:
People involved in industrial sectors or areas of activity such as perfumery, cosmetics, food, plastics and packaging, textile, automotive, detergents, consumer goods, etc.
