3-Hydroxy-4,5-dimethyl-2(5H)-furanone (Sotolon) causing an off-flavor: elucidation of its formation pathways during storage of citrus soft drinks.
Gas chromatography/olfactometry (GCO) and gas chromatography-mass spectrometry (HRGC-MS) revealed 3-hydroxy-4, 5-dimethyl-2(5H)-furanone (sotolon) to be responsible for the "burnt" and "spicy"Expand
Flavor authenticity studies by (2)h/(1)h ratio determination using on-line gas chromatography pyrolysis isotope ratio mass spectrometry.
Based on (2)H/(1)H ratio measurements of commercial synthetic and "natural" references, the recently developed on-line gas chromatography pyrolysis isotope ratio mass spectrometry (HRGC-P-IRMS)Expand
Application of diode array detectors for solute identification in toxicological analysis
SummaryThe possibilities and limitation of automated solute identification via UV/VIS spectroscopy in HPLC are demonstrated and applications in toxicologic analysis are described. A standardExpand
Chemical Composition and Analyses of Enantiomers of Essential Oils from Madagascar
The volatile constituents of twelve essential oils from Madagascar, namely those of Cinnamomum camphora (L.) Presl, Cinnamomum zeylanicum Blume (leaf oil), Hedychium flavum Roxb., HelichrysumExpand
Enantiodifferentiation of α-ketols in sherry by one- and two-dimensional HRGC techniques
The enantiomeric distrubution of solerone (5-oxo-4-hexanolide) 1, ethyl 4-hydroxy- 5-oxohexanoate 2, ethyl 5-hydroxy-4-oxohexanoate 3, 4-oxo-5-hexanolide 4, and solerol (5-hydroxy-4-hexanolide) 5 inExpand
LC-MS study to reduce ion suppression and to identify N-lactoylguanosine 5'-monophosphate in bonito: a new umami molecule?
The influence of ion suppression due to sample matrix effect was investigated and was found to substantially influence the total MS response of N-lactoyl GMP; by adjusting the LC conditions the response could be approximately 5-fold-enhanced. Expand
2H/1H Ratio Analysis of Flavor Compounds by On-Line Gas Chromatography Pyrolysis Isotope Ratio Mass Spectrometry (HRGC-P-IRMS): Benzaldehyde
Isotope ratio monitoring gas chromatography-mass spectrometry of the 2 H/ 1 H ratio by pyrolysis isotope ratio mass spectrometry (P-IRMS) was used to analyze benzaldehyde originating from variousExpand
Enantiomeric Distribution of 2-Pentanethiol in Guava Fruit (Psidium guajava L.) by Multidimensional Gas Chromatography with Sulfur Chemiluminescence Detection
The volatile constituents of guava (Psidium guajava, L.) fruit have already been investigated extensively and a large number of aroma components have been identified [1–3]. Among them the minorExpand
2H/1H ratio analysis of flavor compounds by on-line gas chromatography-pyrolysis-isotope ratio mass spectrometry (HRGC-P-IRMS): citral
Based on 2H/1H measurements of commercial synthetic and natural citral (neral and geranial), on-line gas chromatography–pyrolysis–isotope ratio mass spectrometry (HRGC–P–IRMS) was used to determineExpand
Authenticity assessment of estragole and methyl eugenol by on-line gas chromatography-isotope ratio mass spectrometry.
On-line capillary gas chromatography-isotope ratio mass spectrometry was used in the combustion and pyrolysis modes to determine delta(13)C, delta(2)H, and delta(18)O(SMOW) data of estragole and methyl eugenol originating from various sources, which did not allow differentiation of synthetic 2 from the product of natural origin.
