Mixed-mode solid-phase extraction followed by acetylation and gas chromatography mass spectrometry for the reliable determination of trans-resveratrol in wine samples

The use of a mixed-mode SPE sorbent provides an improvement in the selectivity of the extraction step; moreover, the presence of several intense ions in the electron impact mass spectra of its acetyl derivative guarantees the unambiguous identification of trans-resveratrol.

Analysis of terpenes in white wines using SPE–SPME–GC/MS approach

Terpenes contribute to some white wines aroma, especially these produced from Muscat grapes and others aromatic ones of high terpene contents (Gewurtztramminer, Traminer, Huxel, Sylvaner). Terpenes are present in wine in free and bound (in a form of glycosides) forms.

Flavour characterization of red wines by descriptive analysis and ESI mass spectrometry

Direct infusion electrospray ionization mass spectrometry (ESI-MS) is a new technique that allows for the identification of volatile and non-volatile compounds in foods and beverages, without the need for extraction, isolation and prior chromatographic separation of the sample constituents.

Alternatives for sample pre-treatment and HPLC determination of Ochratoxin A in red wine using fluorescence detection

Ochratoxin A is a mycotoxin widely studied due to its nephrotoxic, immunotoxic, teratogenic and carcinogenic effects. The European Commission has fixed maximum limits for Ochratoxin A in wines and in other foods.
