  1. Volatile components as chemical markers of the botanical origin of Corsican honeys

    A new and faster method for performing honey quality assessments based on HS-SPME/GC/GC-MS analysis was developed using 269 Corsican samples. Identification of chemical markers of the botanical origins of blossom honeys was identified, including 2-aminoacetophenone, p-anisaldehyde, 4-n-propylanisole, isophorone, and isomers of lilac aldehyde. Characterization of the volatile fraction of Corsican honeys combined with chemometric analysis may be useful for detecting the nectar contribution of plant species in honeys.

    In our work, we achieved the apple aroma microcapsules by sodium alginate and tetradecylallydimethylammonium bromide (TADAB) as shells based on complex coacervation-emulsion polymerization. TADAB and SA can be used as wall materials to prepare flavor microcapsules on account of the strong electrostatic interaction between the quaternary ammonium groups and the carboxyl groups. What's more, unsaturated C[DOUBLE BOND]C bond of TADAB could polymerize with comonomer.

  3. Enantioselective syntheses and sensory properties of 2-Alken-4-olides

    A series of optically active 2-alken-4-olides of C6-C11 were obtained with 89-97% enantiomeric excess (ee) values by the Sharpless asymmetric dihydroxylation (AD) of methyl (E)-3-alkenoates, followed by elimination via mesylates. The odor features and thresholds of the enantiomers were determined by means of chiral gas chromatography-olfactory (GC-O). The data revealed that all the samples exhibited stereospecific differences in sensory properties. Both enantiomers of 2-octen-4-olide had the two lowest odor thresholds, whereas two enantiomers of 2-undecen-4-olide presented the two highest odor thresholds.

  4. Inhibition of fermentation evolution in bread doughs for aroma analyses

    • The Fames solution (20 g/L of methyl octanoate/methyl decanoate in dimethyl sulfide) represents an effective, non-toxic alternative to HgCI2 for inhibiting the fermentation evolution (peak areas are visible decreased), achieving accurate aroma analyses of doughs.
    • When the residual fermentation is not inhibited, the yeasts act uncontrolled and there is no logical evolution of the SPME-GC/QT of peak areas of the volatile compounds during fermentation.
    • However, when it is inhibited, there is a logical increase in the SPME-GC/QT of peak areas of the volatile compounds from 0 min to 90 min of fermentation.
  5. Identification of an unusual by-product in the industrial production of 2-Methyl-3-furanthiol

    A by-product provided by the producer of 2-methyl-3-furanthiol was characterized by 1D and 2D NMR, GC–MS (EI) and HRMS analyses. It was identified to be 4-(5-methyl-2-furylthio)-5-methyltetrahydrofuran-2-thione and its precursor 2-methyl-5-thioacetylfuran was also determined. 2-Methyl-5-thioacetylfuran was formed by the nucleophilic addition of AcSH to the aldehyde group of 4-oxo-2-pentenal during the industrial production of 2-methyl-3-furanthiol. The hydrolysis of 2-methyl-5-thioacetylfuran under basic conditions gave 5-methyl-2-furanthiol, which underwent autothiylation to lead to the formation of 4-(5-methyl-2-furylthio)-5-methyltetrahydrofuran-2-thione.
