Non-alcoholic beers are becoming more popular and need to reflect the sophisticated flavourings of beers that are brewed containing alcohol. Sophisticated analytical techniques can help to achieve this.
Rising Stars of Separation Science: David Steiner
March 27th 2024This month we interview David Steiner, head of product development at LVA GmbH–Lebensmittelversuchsanstalt in Klosterneuburg, Austria about his work developing liquid chromatography–tandem mass spectrometry (LC–MS/MS) multiclass methods for classification of feedstuff, including replication of model complex feedstuffs in the analytical laboratory.
Profiling VOCs in Whisky with GC×GC–MS
March 6th 2024Researchers from Austria, Greece, and Italy conducted a study to analyze volatile organic compounds (VOCs) present in Irish and Scotch whiskys using solid-phase microextraction (SPME) Arrow with comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC–MS) to examine the organoleptic characteristics that influence the taste of spirits.
Entering Another Dimension: The Benefits of Multi‑2D LC×LC in Food Analysis
February 15th 2024Lidia Montero and Miguel Herrero from the Institute of Food Science Research in Spain discuss the evolving role of comprehensive two-dimensional liquid chromatography (LC×LC) and multi-second dimension LC×LC (multi-2D LC×LC) in food analysis.
Q&A: Unraveling the Dynamics of GM3 Gangliosides in Human Milk Across Lactation Stages
February 1st 2024Weronika Hewelt-Belka, an assistant professor at Gdańsk University of Technology in Poland, answers questions about her research analyzing GM3 gangliosides in human milk, elucidating their molecular distribution and dynamic changes throughout lactation.
Unveiling Phenolic Pollutants in Dairy Products: A Breakthrough Analysis
February 1st 2024A recent study conducted at the University of Jaén in Spain, unveils the presence of 21 phenolic pollutants, including bisphenols and alkylphenols, in milk and dairy products, with significant concentrations detected in items packaged in materials such as polystyrene terephthalate and multilayer packaging, emphasizing the importance of packaging choices in minimizing phenolic contamination.
HPLC Methods with Different Detection Types Determine Whey Protein Content in Cheese
February 1st 2024High performance liquid chromatography (HPLC) was paired with both diode array and fluorescence detection (DAD and FLD, respectively) to measure Edam cheese for its total and acid-soluble whey content.
Q&A: FDA Talks to LCGC About Chromatographic Techniques for PFAS Detection in Food Supply
October 13th 2023FDA scientists have expanded the number of analytes in their analytical method for per- and polyfluoroalkyl substances (PFAS), partly in response to updated guidance out of the European Union (EU) on method parameters and limits of quantification (LOQs).
Scientists used supercritical fluid chromatography (SFC) and ultrahigh-pressure liquid chromatography (UHPLC)—both coupled with high-resolution mass spectrometry (HRMS)—to analyze various types of chlorinated paraffins (CPs) in fish oil-based dietary supplements.
