Special Issue Information

Dear Colleagues,

Volume I (https://www.mdpi.com/journal/foods/special_issues/FBE52KXD25) of this Special Issue was incredibly successful. We would like to express our gratitude to everyone involved for their participation.

Chromatography has become indispensable for the qualitative and quantitative analysis of a vast number of compounds in complex mixtures. In particular, gas chromatography (GC) and high-performance liquid chromatography (HPLC) have been widely used in different fields of food science. These techniques are often coupled to mass spectrometers, which are increasingly recognised as powerful tools for the unequivocal identification of specific compounds. HPLC-MS and GC-MS have been subjected to extensive and continuous improvements, allowing for the detection of bioactive compounds, food contaminants, toxins, and aroma compounds in different food matrices. Notwithstanding the importance of technological improvements, the development of new methods of extraction has made a remarkable contribution to food analysis.

In recent years, there has been a growing interest in the analysis of trace levels of several compounds, which may have a relevant impact on food quality. Despite the recent advances, the analysis of components at very low levels in complex matrices is still often a challenge. Therefore, this Special Issue in Foods aims to gather the latest research and advancements addressing the application of chromatographic and mass spectrometry methods in food science.

We encourage authors to share their scientific achievements in original research or review articles regarding the applications of these techniques in the analysis of naturally occurring compounds, food additives, and contaminants in different food sources. Potential topics include, but are not limited to, the identification and quantitation of food bioactive compounds, flavour and aroma compounds, environmental pollutants, adulterants, pesticides, mycotoxins, natural toxins, veterinary and human drugs, and the toxins generated during food processing and packaging materials. The development and validation of extraction and chromatographic methods, the identification of existing challenges and possible future approaches will also be considered.

We look forward to your valued contribution.

Fluoroquinolones (FQs) are present in trace amounts in the environment, from where they enter animal- and plant-derived food products. Long-term exposure to low-dose drugs poses a risk to human health and increases the pressure on antibiotic selection. Based on previous aptamer screening with [...] Read more.
Fluoroquinolones (FQs) are present in trace amounts in the environment, from where they enter animal- and plant-derived food products. Long-term exposure to low-dose drugs poses a risk to human health and increases the pressure on antibiotic selection. Based on previous aptamer screening with high FQs specificity, this study combined a new aptamer recognition probe with a metal–organic framework (MOF) to obtain a sample pretreatment composite material with strong FQs specificity for multi-target analysis. Residual FQs were extracted from the complex food matrix via magnetic dispersive solid-phase extraction and examined using high-performance liquid chromatography. The method showed good linearity in a range of 0.39 to 200 µg/kg for five FQs in milk and fish samples, with a detection limit of 0.04–0.10 µg/kg and a quantitative limit of 0.13–0.33 µg/kg. This study successfully developed an effective sample pretreatment material and methodology for trace FQs identification in complex animal-derived food matrices. Full article
