Food and Beverage Analysis

A group of Taiwanese scientists have recently created a new method for assessing food quality and detecting histamine in wine samples.

Lidia 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.

The 18th International Symposium on Hyphenated Techniques in Chromatography and Separation Technology will take place from 28–31 May 2024 in Leuven, Belgium.

Weronika 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.

A 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.

High 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.

The process was assisted by pH-dependent acid-base partitioning coupled with salting-out-assisted liquid-liquid extraction (LLE).

Researchers at the Shanghai Academy of Agricultural Sciences have developed a new magnetic solid-phase extraction method using MIL-101(Cr)@Fe3O4 nanocomposites, detailed in the Food Control journal, enabling the efficient and simultaneous detection of multiple mycotoxins in agricultural products, potentially impacting food and feed safety standards.

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.

A new study details the US Food and Drug Administration (FDA)’s recent expansion to 30 analytes, from a previous 16, in the method for determining per- and polyfluoroalkyl substances (PFAS) in the US food supply, which, in turn, may mean that additional analytes may still yet be identified (1).

The author describes the benefits of using high-capacity sorptive extraction and statistical analysis to detect authenticity markers and combat food fraud in honey samples.

A collaborative multi-analyte method developed utilizes HPLC and UHPLC to analyze more than 70 active ingredients. This method offers a validated approach for determining technical AI alongside linearity, precision, accuracy, and specificity tests for seven active ingredients.

FDA 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).

At this year’s AOAC International Annual Meeting, held in New Orleans, Louisiana, nearly 700 analytical scientists were honored in an awards ceremony.

LCGC spoke to Hans-Gerd Janssen from the Unilever Foods Innovation Centre in The Netherlands about the advantages of a novel, rapid method to analyze antioxidants that inhibit oxidation.

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.

Professor Kieran N. Kilcawley of Teagasc Food Research Centre and of University College Cork and his colleagues are using gas chromatographic (GC) techniques to explore how to analyze the quality and taste of Irish whiskeys through congener profiles.

Scientists based out of Zhejiang Academy of Agricultural Sciences in Hangzhou, China, recently used a new QuEChERS method for analyzing pesticides in fruit samples.
