| Abstract: | "BACKGROUND: The quality and power of each odorous volatile present in the headspace of unifloral honey velame branco (Croton heliotropiifolius Kunth) prepared by stingless urucu (Melipona scutellaris Latrelle) were evaluated using the gas chromatography-olfactometry Osme technique. Five trained panellists evaluated the sensory chromatographic effluent in three replications, and the results were integrated by SCDTI software. RESULTS: Of the 42 compounds identified in the chromatogram, 17 odorous stimuli were detected by the sensory panel. Among these compounds, the most odoriferous impacts were pentanoate acetate 'ripe fruit', safranal green, medicinal plant and methyl eugenol 'clove, tea'. The furaneol compounds, hotrienol and benzaldehyde showed aroma notes associated with honey. CONCLUSION: These results are important since, in addition to revealing the presence of compounds that are not identified by other analytical methods, they can also assist in the verification of monofloral honeys compliance.
