Special Issue Information

Dear Colleagues,

In recent years, endocrine disruptors have sparked increasing interest on account of their highly adverse effects on human health and, especially, their ability to induce infertility and cancer. These substances and various others are frequently encountered in foods as a result of environmental contamination or their presence in animal feed. In addition, these contaminants are often present in food packaging plastics and other materials, from which they can migrate into food and water. Regulatory bodies are increasingly concerned with their control, which requires using methods capable of detecting them with high sensitivity, accuracy, and precision. Two additional problems in developing such methods arise from the complexity of food matrices and the fact that endocrine disruptors are usually present at exceptionally low, trace levels in foods. This requires using effective sample treatments to reduce matrix effects and preconcentrate the analytes.

The aim of this Special Issue of Foods is to disseminate novel methods for determining endocrine disruptors and other contaminants potentially present in food, with special emphasis on effective extraction procedures and quantitation with gas chromatography and liquid chromatography coupled to mass spectrometry. Both original research and review articles are welcome.

Dairy products can be contaminated by parabens and phenolic compounds from a vast variety of sources, such as packaging and manufacturing processes, or livestock through feed and environmental water. A two-step continuous solid-phase extraction (SPE) and purification methodology was developed here for the determination of both types of compounds. In the first step, a sample extract is passed in sequence through an EMR-lipid sorbent and an Oasis PRiME HBL sorbent to remove fat and preconcentrate the analytes for subsequent detection and quantification by UHPLC−MS/MS. This method enabled the determination of 28 parabens and phenolic contaminant with excellent recovery (91–105%) thanks to the SPE sorbent combination used. The proposed method was validated through the determination of the target compounds, and was found to provide low detection limits (1–20 ng/kg) with only slight matrix effects (0–10%). It was used to analyse 32 different samples of dairy products with different packaging materials. Bisphenol A and bisphenol Z were the two phenolic compounds quantified in the largest number of samples, at concentrations over the range of 24–580 ng/kg, which did not exceed the limit set by European regulations. On the other hand, ethylparaben was the paraben found at the highest levels (33–470 ng/kg). Full article
