Analytical Techniques in the Wine Industry
The Montreal Gazette published an article about the use of analytical techniques in the wine industry. The author discusses the difference between "natural" wines and "industrial" wines that are created with a certain taste profile in mind and with the assistance of gas chromatography.
The Montreal Gazette published an article about the use of analytical techniques in the wine industry. The author discusses the difference between "natural" wines and "industrial" wines that are created with a certain taste profile in mind and with the assistance of gas chromatography.
While the author laments that analytical techniques take away the unique, regional flavors of traditional wines, we are more interested in the subtext of what he is saying: Chromatography and mass spectroscopy have helped the wine industry produce great tasting wines at affordable prices. And that is something that should make any and every analytical scientist in the food and beverage industry proud.
In a LCGC North America article, Buglass and Lee described the applications of SPE and chiral ligand?exchange chromatographic method and a HPLC column-switching method to the analysis of the lactic acid enantiomer content of wine. The LCGC Application Notebook has featured several notes on the analysis of wine and alcohol such as a note on the determination of wine using a MS-based chemical sensor and a note on the determinations of alcohols and glycols in a wine sample using ion-exclusion chromatography (ICE) and pulsed amperometric detection (PAD).
Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
SPE-Based Method for Detecting Harmful Textile Residues
January 14th 2025University of Valencia scientists recently developed a method using solid-phase extraction (SPE) followed by high-performance liquid chromatography coupled to high-resolution mass spectrometry (HPLC–HRMS/MS) for detecting microplastics and other harmful substances in textiles.
