The aim of this research was to develop and validate a headspace-solid phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) method for the determination of volatile emerging contaminants in fruit. The method showed good precision (RSD ≤ 14%) and satisfactory recoveries (99.1-101.7%) and LOD and LOQ values ranging between 0.011-0.033 μg kg and 0.037-0.098 μg kg, respectively. The method was applied to investigate the content of volatile emerging contaminants in two varieties of melon fruit (Cucumis melo L.) cultivated adjoining high-risk areas. Glycol ethers, BHT, BHA and BTEX (benzene, toluene, ethylbenzene and xylene) were determined in melon fruit pulps for the first time, with different sensitivities depending on sample and variety. Although the amount of the volatile contaminants in the melon samples were in the order of µg kg, the safety of vegetable crops cultivated near risk areas should be more widely considered. The results showed that this accurate and reproducible method can be useful for routine safety control of fruits and vegetables.

Evaluating the olfactory preferences of emerging insect pests is critical to develop monitoring tools and improve early detection and management strategies. Here the chemical ecology and olfactory preferences of the allium leafminer Phytomyza gymnostoma Loew (Diptera: Agromyzidae), an invasive pest in North America affecting allium crops such as leeks and onions, were investigated. Three bioassay methods were assessed under laboratory conditions: wind tunnel, Y-tube olfactometer, and arena bioassay.

Background: Emergence agitation is common after nasal surgery under general anaesthesia. Remimazolam, a novel ultra-short-acting benzodiazepine, allows haemodynamic stability and prompt postoperative recovery, but the specific impact of remimazolam on emergence agitation is not well understood.
Objectives: The primary aim of this study was to compare the effects of remimazolam-based total intravenous anaesthesia (TIVA) and sevoflurane-based volatile induction and maintenance of anaesthesia (VIMA) on the occurrence of emergence agitation.

Pu-erh raw tea (PRT), a post-fermented tea, is prized for its complex flavor profile and health-promoting properties. While extended storage enhances its sensory attributes, the decade-scale metabolic dynamics underpinning flavor evolution remain unexplored. This study comprehensively characterized non-volatile metabolomic profiles and flavor changes in PRT across a 10-year storage period (2012-2023).

Food spoilage poses a global challenge with far-reaching consequences for public health, economic stability, and environmental sustainability. Conventional analytical methods for spoilage detection though accurate are often cost-prohibitive, labor-intensive, and unsuitable for real-time or field-based monitoring. Microfluidic paper-based analytical devices (μPADs) have emerged as a transformative technology offering rapid, portable, and cost-effective solutions for food quality assessment.

Essential oils (EOs) are secondary metabolites of plants, made up of a wide range of aromatic volatile compounds found in different concentrations. These essential oil components (EOCs) are widely recognized for their diverse biological activities, including antibacterial, antifungal, and antioxidant properties, among others. Consequently, EOs have garnered significant interest across various industries, such as pharmaceutical, agri-food, and perfumery.
