Special Issue Information

Dear Colleagues,

Food safety is a major international concern. In fact, a vast number of foodborne acute and chronic diseases are related to the consumption of contaminated food by biotic and/or xenobiotic compounds. Thus, there is an ever-increasing demand for reliable analytical methods that enable the rapid screening of food contaminants also at low concentration levels. Among the various stages of the analytical process, sample preparation and, specifically, the step involving the extraction of analytes, represents the most critical phase in the attainment of reliable results. In this contest, solid-phase microextraction (SPME) could be useful, enabling volatile and semi-volatile compounds to be extracted without the utilization of organic solvents; this could combine, in a single step, the analyte extraction and concentration phases.

Due to the widespread use of plastics, today, considerable attention is paid to human exposure to phthalates (PAEs;  key additives in many plastics to keep them soft at room temperature) owing to their suspected carcinogenic and estrogenic properties. Therefore, the development of alternative packaging materials that can enhance the shelf-life of foods is vital.

It is our pleasure to invite you to contribute your research article, communication paper, or review to this Special Issue dedicated to the development of SPME procedures for the GC–MS analysis of food contaminants and/or packaging materials.

Phthalates are the synthetic chemical plasticizers with the most varied uses and are a source of concern due to their toxicity and ubiquity, so much so that even plasticizer-free polymers can contain them as non-intentionally added substances (NIAS). Food packaging is among the materials with the greatest impact. In this study, a simple protocol is proposed for the location and identification of dimethyl phthalate, diethyl phthalate, dipropyl phthalate, and dibutyl phthalate which is applicable to compliance studies of food packaging materials and for the associated risk assessment. Solid phase microextraction gas chromatography/mass spectrometry was used to evaluate the migration of four NIAS from food packaging to release media simulating food substrates. Three plasticizer-free polymers were used: two that were lab-made and based on sodium alginate and a commercial polyethylene film. Linearity ranged from the LOQ to 10 µg/mL; within-day and between-day precision values were between 12.3–25.7% and 21.9–35.8%, respectively; the LOD and LOQ were in the range 0.029–0.073 µg/mL and 0.122–0.970 µg/mL. Migration tests were conducted for different periods of time at room temperature and at 8 °C. Exposure to microwaves (MW) was also evaluated. All packaging materials tested had global migration limits lower than 10 mg/dm2 of material surface. Full article
