Sanyo Chemical Industries has begun selling FlavoTone, a scent sensor that can visualize complex and diverse scents.
FlavoTone can visualize not only specific scents but also complex scents, so it can provide solutions such as quality control, characteristic comparison, and monitoring based on scent.
The company not only sells equipment, but also provides services such as rental, contract analysis, and proposing solutions to individual problems.

The human nose is thought to identify scents by emitting electrical signals from olfactory cells when scent molecules adsorb to olfactory receptors, and transmitting these signals to the brain.

FlavoTone uses a mechanism similar to this olfactory sense, using scent-responsive materials that correspond to olfactory receptors, probes that detect scents by changes in electrical properties due to adsorption of scent molecules, and analysis that identifies scents from the obtained signal patterns. It is a device that consists of an app and can visualize complex scents. Compared to response materials for conventional scent sensors, it is relatively easy to vary the response characteristics to scent molecules over a wide range, and it is relatively unaffected by external environments such as humidity.
