In this research we studied the olfactory sensitivity to banana head-space as a complex odor mixture in a group of 53 subjects classified for their olfactory status, by means of the “Sniffin’ Sticks” extended test. Using the coupled Gas Chromatog.-Mass Spectrometry/ Olfactometry (GC-MS/O) technique, the single components of the banana flavor mixture were separated, identified and verbally evaluated by each subject. For each compound both the “odor type” (i.e., odor quality: fruity, floral, green, etc.) and “odor descriptor” (i.e., name used by subjects for odor identification) were reported, so that we could identify mols. that were defined as smelling of banana. The results show that: (a) the threshold olfactory performance is linearly correlated with the number of odor-active compounds (total or smelling of banana) for each subject; (b) the intensity reported by each subject during the sniffing of the pen containing the banana aroma in the identification test is pos. correlated both with its hedonic valence and the number of odor-active compounds smelling of banana. In conclusion, our findings show that human perception of single compounds is conditioned by the threshold olfactory performance of the subject and that his/her ability to detect single mol. components, which smell as the mixture, affects the intensity and hedonism for the complex aroma. In the experiment, the researchers used many compounds, for example, Isopentyl 3-methylbutanoate (cas: 659-70-1Application of 659-70-1).
Isopentyl 3-methylbutanoate (cas: 659-70-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application of 659-70-1
