Headspace SPME Used to Analyze Cheese Flavors
Researchers at Agriculture and Agri-Food Canada (St-Hyacinthe, Quebec, Canada) and McGill University (Ste-Anne-de-Bellevue, Quebec, Canada) used headspace solid-phase microextraction (SPME) in conjunction with gas chromatography?mass spectrometry (GC?MS) to measure flavor compounds in commercial cheddar cheese and enzyme-modified cheddar cheese.
Researchers at Agriculture and Agri-Food Canada (St-Hyacinthe, Quebec, Canada) and McGill University (Ste-Anne-de-Bellevue, Quebec, Canada) used headspace solid-phase microextraction (SPME) in conjunction with gas chromatography?mass spectrometry (GC?MS) to measure flavor compounds in commercial cheddar cheese and enzyme-modified cheddar cheese. The group looked at seven target compounds: dimethyl disulfide, hexanal, hexanol, 2-heptanone, ethyl hexanoate, heptanoic acid, and delta-decalactone. They tested three SPME fiber types, including Carboxen?polydimethylsiloxane, polyacrylate, and Carbowax?divinylbenzene and examined the effects of varying sodium chloride concentration, temperature, and extraction time on the outcome of the extraction process.
The Use of SPME and GC×GC in Food Analysis: An Interview with Giorgia Purcaro
December 16th 2024LCGC International sat down with Giorgia Purcaro of the University of Liege to discuss the impact that solid-phase microextraction (SPME) and comprehensive multidimensional gas chromatography (GC×GC) is having on food analysis.

Professor Bogusław Buszewski of Nicolaus Copernicus University in Torun, Poland, has been awarded the prestigious Martin Medal, and the 2025 Silver Jubilee Medal has been awarded to Elia Psillakis of the Technical University of Crete in Greece.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
