How to Visualize a Potential Aromatic Map of a Product in the Odor Space: The Sketchoscent Approach

Résumé

The representation of an odor space is a challenging issue for scientists and professionals working in odor-related activities. Such representations are regularly attempted to provide a common frame of reference to professionals or sensory analysis judges. These initiatives generally classify hierarchically a limited set of odorants in defined categories and turn the odorant space into a simplified representation associated with a graphical visualization. However, these representations do not reflect the actual continuum and overlapping of odors engendered by molecules, their possible description by different levels of accuracy or their belonging to several categories. To overcome these difficulties, we recently proposed the SketchOscent approach (https://oniris-polytech.univ-nantes.io/sketchoscent), an easy-to-use and open-access tool which is founded on a cartographic metaphor of the odor space that reflects the above-mentioned specificities. The work presented here aims to take advantage of this map in order to improve the understanding of the odorant/aromatic perception of products. Indeed, the olfactive perception of a product results from the expression of a set of volatile odorant molecules it contains. The sketchOscent mapping is based on databases that include more than 7700 molecules contained in 8800 products and 380 hierarchical odorant descriptors. It takes into account both sensory and conceptual perceptions. More precisely, it enables to highlight a possible aromatic palette of a product by providing a set of locations in the map, embedding its potential odorants. Following cartographic principles, the map of all locations remains stable in order to keep the user's mental representation and facilitate the comparison between products. Several illustrations are provided to visualize the odor map of different products and compare them. This approach, mainly dedicated to foods, can be useful to pick up relevant terms to describe perceptions or for food-pairing type applications, but may be amended to larger sectors of activities.
