Special Issue Information

Dear Colleagues,

Nowadays, ensuring food safety and quality has become a primary concern in the food industry, necessitating the addressing of new challenges to safeguard consumer health and meet their evolving demands. Consequently, it is becoming increasingly common to devise novel analytical methodologies that are not only rapid, sensitive and selective, but also environmentally friendly, thus facilitating the assessment and improvement of food safety and quality. Given the nature of food matrices, sample treatment prior to analysis is indispensable. Integrating these green and micro-extraction methods with advanced analytical tools such as chromatography coupled to mass spectrometry provides a comprehensive and sustainable approach to characterizing active and toxic components in food.

This Special Issue serves as a call for the latest groundbreaking methodologies employed in the identification and quantification of active and toxic compounds in food samples. It encompasses an extensive range of substances, including active compounds (terpenoids, phenolic compounds, vitamins, sulfur compounds, etc.), natural toxins such as mycotoxins, plant alkaloids (pyrrolizidine, tropane, opium alkaloids, glycoalkaloids), processing contaminants (acrylamide, polycyclic aromatic hydrocarbons, etc.), heavy metals, microplastics or veterinary drugs.

Authors are encouraged to contribute original research articles or comprehensive review papers that highlight the potential of new analytical strategies for ensuring food safety and quality.

This work focuses on the development of a hybrid material based on SBA-15 silica with a molecularly imprinted polymer (MIP), using spiramycin (SPI) as a template, for use as sorbent in solid-phase extraction (SPE). Characterization techniques such as nitrogen gas adsorption–desorption isotherms, infrared spectroscopy and scanning electron microscopy confirmed the structure and properties of the SBA-15@MIP-SPI material. SPE conditions using SBA-15@MIP-SPI as sorbent were optimized, which allowed us to demonstrate the high selectivity and adsorption capacity of SPI on the synthesized material. The best conditions were 50 mg of sorbent, loading with 1 mL of standard solution or sample of cow milk previously extracted in acetonitrile and eluting with 3 mL of methanol with 1% acetic acid. After the optimization process, the material demonstrated recovery percentages of 81 ± 3% in SPI standard solutions and showed its potential in cow milk samples (71 ± 6%). The novelty of the research consists of the combination of MIPs with SBA-15, which could offer important advantages in terms of specific surface area and porous structure, thus improving performance and reducing the amount of sorbent compared to other traditional methods.

Title: In vitro assessment of phenolic grape pomace extracts as potential use as phytotherapeutic agents

Abstract: Grape pomace, a by-product of the winemaking industry, contains bioactive molecules such as phenolic acids, flavonoids, and anthocyanins, with potential health benefits. In the current study, these bioactive molecules were extracted from grape pomace using microsolid-phase extraction (µSPEed®) procedure. The grape pomace extracts were analyzed by ultra-high performance liquid chromatography (UHPLC-PDA) to establish the phenolic profile and by in vitro assays to assess the antioxidant, anti-inflammatory, and anti-bacterial activities. As far as we know, µSPEed® is being used for the first time in the extraction of phenolic compounds from GP, leveraging its enhanced efficiency and reduced solvent usage to make it a more sustainable and effective method compared to traditional extraction techniques. The methods were fully validated for selectivity, sensitivity, precision, and accuracy. Furthermore, the phenolic compounds will be correlated with their antioxidant activities using Pearson correlation
