Multivariate statistical analysis of a large odorants database aimed at revealing similarities and links between odorants and odors
2017
International audience; The perception of odor is an important component of smell; the first step of odor detection, and the discrimination of structurally diverse odorants depends on their interactions with olfactory receptors (ORs). Indeed, the perception of an odor's quality results from a combinatorial coding, in which the deciphering remains a major challenge. Several studies have successfully established links between odors and odorants by categorizing and classifying data. Hence, the categorization of odors appears to be a promising way to manage odors. In the proposed study, we performed a computational analysis using odor descriptions of the odorants present in Flavor-Base 9th Edit…
Exploring the odorant and molecular characteristics of molecules sharing the odour notes of an aroma blending mixture

Online event (Live and on-demand); International audience; To perceive a huge number of odors from few hundreds ORs, the human olfactory system encodes odor identities by an olfactory scheme whereby one olfactory receptor (OR) recognizes multiple odorants while one odorant activates different combinations of ORs [1, 2]. Odors perceived in our environment are mainly the result of mixtures of odorants, but the specific mechanisms involved in their processing remain poorly understood [3]. In previous studies performed at INRAE-CSGA [4], the perception of a mixture of ethyl isobutyrate (Et iB, strawberry-like odor, STR) and ethyl maltol (Et-M, caramel-like odor, CAR) was investigated in compari…
