Methoxypyrazine composition of Coccinellidae‐tainted Riesling and Pinot noir wine from Germany

Journal of the Science of Food and Agriculture, 2014
AbstractBACKGROUNDHarmonia axyridis (multicolored Asian ladybeetle) and Coccinella septempunctata (seven‐spot ladybeetle) (Coccinellidae) are found in many wine regions in Europe and the Americas, where they are responsible for a pronounced wine fault known as ‘ladybug taint’ when incorporated with grapes during harvest operations.

Automated analysis of geosmin, 2-methyl-isoborneol, 2-isopropyl-3-methoxypyrazine, 2-isobutyl-3-methoxypyrazine and 2,4,6-trichloroanisole in water by SPME-GC-ITDMS/MS

International Journal of Environmental Analytical Chemistry, 2011
This paper describes a method of determining the following compounds in water characterised by complex matrices (raw waters and drinking waters): geosmin, 2-methylisoborneol (2-MIB), 2-isobutyl-3-methoxypyrazine (IBM), 2-isopropyl-3-methoxypyrazine (IPM) and 2,4,6-trichloroanisole (TCA).

Headspace solid-phase microextraction analysis of 3-alkyl-2-methoxypyrazines in wines

Journal of Chromatography A, 2002
A procedure to determine 3-alkyl-2-methoxypyrazines in wines is described. It is based on the headspace solid-phase microextraction (HS-SPME) technique after a clean-up of the sample by distillation (previously acidified to pH 0.5) to remove ethanol and other volatile compounds that can interfere in the SPME.
