Gas chromatography-mass spectrometry method optimized using response surface modeling for the quantitation of fungal off-flavors in grapes and wine.
J. Agric. Food Chem. 63(11) , 2877-85, (2015) An optimized method for the quantitation of volatile compounds responsible for off-aromas, such as earthy odors, found in wine and grapes was developed. The method involved a fast and simple headspace solid-phase microextraction-gas chromatography-mass spectr... |

Entropic cost of protein-ligand binding and its dependence on the entropy in solution.
J. Phys. Chem. B 113(17) , 5871-84, (2009) Two theoretical formulations are proposed and compared for the loss of translational and rotational entropy upon protein-ligand binding in water. The two theories share the same approach to evaluate the translational and rotational entropy of the ligand when ... |

Occurrence of dissolved and particle-bound taste and odor compounds in Swiss lake waters.
Water Res. 43(8) , 2191-200, (2009) The occurrence of algal taste and odor (T&O) compounds was investigated in three Swiss lakes which exhibit different nutrient levels from eutrophic to oligotrophic (Lake Greifensee, Lake Zurich and Lake Lucerne). Apart from dissolved T&O compounds, the study ... |

Rapid measurement of 3-alkyl-2-methoxypyrazine content of winegrapes to predict levels in resultant wines.
J. Agric. Food Chem. 57(18) , 8250-7, (2009) We describe an optimized protocol for analysis of the herbaceous smelling 3-alkyl-2-methoxypyrazines (MPs) in whole berries that predicts MPs in resultant red wines. Berries are homogenized by bead-milling with a deuterated standard prior to headspace solid p... |

Automated trace determination of earthy-musty odorous compounds in water samples by on-line purge-and-trap-gas chromatography-mass spectrometry.
J. Chromatogr. A. 1136(2) , 170-5, (2006) An automated technique based on purge-and-trap coupled to gas chromatography with mass spectrometric detection has been developed and optimized for the trace determination of five of the most important water odorants; 2-isopropyl-3-methoxypyrazine, 2-isobutyl... |

Development of a mixed-mode solid phase extraction method and further gas chromatography mass spectrometry for the analysis of 3-alkyl-2-methoxypyrazines in wine.
J. Chromatogr. A. 1218(6) , 842-8, (2011) A new method for analysing 3-isopropyl-2-methoxypyrazine, 3-sec-butyl-2-methoxypyrazine and 3-isobutyl-2-methoxypyrazine in wine has been developed and applied to wine. The analytes are extracted from 25 mL of wine in a solid-phase extraction cartridge filled... |

Determination of ortho- and retronasal detection thresholds for 2-isopropyl-3-methoxypyrazine in wine.
J. Food Sci. 72(7) , S468-72, (2007) 2-Isopropyl-3-methoxypyrazine (IPMP) is a grape-derived component of wine flavor in some wine varieties as well as the causal compound of the off-flavor known as ladybug taint (LBT), which occurs when Harmonia axyridis beetles are incorporated with the grapes... |

Detection thresholds for 2-isopropyl-3-methoxypyrazine in Concord and Niagara grape juice.
J. Food Sci. 73(6) , S262-6, (2008) 2-isopropyl-3-methoxypyrazine (IPMP) is the compound responsible for the off-flavor known as ladybug taint, which occurs when Harmnonia axyridis beetles become incorporated with the grapes during juice processing. It is also an important grape-derived compone... |

Removal of earthy-musty odorants in drinking water by powdered activated carbon.
J. Environ. Sci. Health. A. Tox. Hazard. Subst. Environ. Eng. 40(4) , 767-78, (2005) The removal of four earthy-musty compounds, 2-methylisoborneol (MIB), 2,4,6-trichloroanisole (TCA), 2-isopropyl-3-methoxy-pyrazine (IPMP), and 2-isobutyl-3-methoxy-pyrazine (IBMP), by powdered activated carbon (PAC) were investigated under the simulative cond... |
