Trace-level pesticides and environmental pollutants in the food supply continue to be a worldwide concern. Here we present a fast-screening workflow for residual pesticides present on the surface of fruits using a GC–MS system with direct heating technology and MS spectral deconvolution.

Mycotoxins are toxic metabolites produced by fungal species often found in agricultural products. An accurate method for analyzing 12 regulated mycotoxins is described using UHPLC–MS/MS. The method demonstrated limits of quantitation (LOQs) for all analytes below stringent regulatory limits, making the method suitable for routine mycotoxin analysis.
Hydrolyzed collagens (collagen peptides) are water-soluble products obtained by hydrolysis of natural proteins and used for dietary supplements. A simple GPC/SEC method is described for molar mass determination of collagen peptides, allowing reliable molar mass determination using ultraviolet (UV) detection.
A fully automated quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction and extract clean-up method is described for analysis of organophosphate pesticides in orange juice. This method uses GC–MS and LC–MS along with an industry standard robotic x,y,z-sampling system.

An overview of the analytical approaches proposed, from sample preparation to the final chromatographic determination, for the reliable risk assessment of mineral oil hydrocarbon (MOH) contaminants in food. The analysis of these contaminants in food is a challenging task and requires a comprehensive approach to tackle the cumbersome issues related to their determination.

An increasing range of per- and polyfluoroalkyl substances (PFAS) has been found migrating from food contact material into food. This article establishes an integrated analytical approach combining HPLC–MS/MS and GC–MS/MS to detect 36 such PFAS.
High-capacity sorptive extraction combined with thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS) can improve on traditional methods for the analysis of VOCs and other trace analytes that contribute to the aroma, flavor, and safety of food products.

This study demonstrates how the technique can improve on traditional methods in the analysis of VOCs that contribute to the aroma and flavour of a breakfast cereal and in identifying other compounds of interest, such as food additives, contaminants, and potentially toxic compounds at trace levels.
