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.
