Summary: The study focused on the extraction and fractionation of sulfur-containing compounds from vacuum gas oil using non-reactive methods such as ligand exchange chromatography and molecularly imprinted polymer. Different sorbents and cations were used to isolate specific sulfur compounds, resulting in varying degrees of selectivity and separation efficiency. Further analysis by high-performance liquid chromatography coupled with atmospheric pressure chemical ionization Orbitrap mass spectrometry allowed for the detection of a wider range of sulfur compounds with different degrees of unsaturation.

Summary: Accelerated urbanization and industrialization have led to increased generation of wastewater with complex chemical contents, posing a threat to water quality. Understanding the chemical characteristics and pollution sources of industrial wastewater is crucial for effective water treatment strategies. This study conducted a non-target chemical analysis of industrial wastewater samples from a chemical industrial park in China, identifying volatile and semi-volatile organic compounds. Priority was given to persistent, mobile, and toxic substances that could impact drinking water resources. The source analysis revealed the dye production industry as the largest contributor of toxic contaminants. The results provide valuable information for risk-based wastewater management and source reduction strategies.

Summary: The ion conversion processes in CH2Cl2-enhanced vacuum ultraviolet photoionization of oxygenated volatile organic compounds (OVOCs) were studied by regulating pressure, humidity, and reaction time in the ionization source. The main characteristic ions changed with varying pressure, and interconversion between ions through ion-molecule reactions was observed with increasing humidity. The intensity of protonated methanol/ethanol ion was linearly correlated with the intensity of hydrated hydronium ions, indicating a proton transfer reaction mechanism. The reaction time was regulated by the electric field strength, and step-by-step ion-molecule reactions were observed. This study provides insights into the formation mechanism of intermediate product ions and hydrated hydronium ions in dopant-enhanced VUV photoionization and helps optimize experimental conditions for enhancing the sensitivity of OVOCs.

Summary: GC-TOF/MS and GC x GC-TOF/MS were used to detect VOCs in coffee samples of three different brands at different states. The results showed that most VOCs existed in 2-3 kinds of coffee, and the VOCs detected by GC-TOF/MS could distinguish the coffee samples in different states. GC x GC-TOF/MS was suitable for the identification and differentiation of different brands of coffee samples. Pyridine, pyrrole, alcohols, and phenols contributed greatly to distinguishing coffee in three states, and alcohols greatly contributed to distinguishing the three brands of coffee.

Summary: The flavor of beauty tea can be influenced by the degree of leafhopper puncturing. This study analyzed the metabolites of fresh tea leaves and beauty tea with different degrees of puncturing. Low-puncturing beauty tea showed higher quality. Various differential metabolites, including tea polyphenols, saccharides, and lipids, were identified. Isomaltulose, theaflavic acid, and ellagic acid were found to be characteristic metabolites contributing to the different taste outlines of beauty tea. Additionally, dihydrolinalool and cis-linalool oxide were identified as characteristic volatile components responsible for the different aroma of beauty tea. These findings provide a theoretical basis for raw material selection, quality research, and industrial development of beauty tea.

Summary: This study uses GC-APCI-MS/MS to detect and identify 8 herbicide residues in plant-based foodstuffs. APCI, as a soft ionization technique, enhances sensitivity and selectivity by generating more molecular ions and/or protonated molecules. The method has a range of 0.5 to 50 ng/mL for calibration curves, with recoveries in the range of 76.3-108.5%. The limit of quantification for all samples is 1.0 μg/kg. The results demonstrate the potential of GC-APCI-MS/MS in routine detection and identification of herbicide residues in plant-based foodstuffs.

Summary: GC x GC-O-TOF-MS and GC-IMS have been increasingly used in complex food flavor analysis, but few studies have applied these techniques to identify the aroma components of tomato pastes. This study comprehensively characterized the aroma profiles of cold and hot break tomato pastes using SAFE-GC-O-MS, SAFE-GC x GC-O-TOF-MS, and HS-GC-IMS for the first time. A total of 274 volatile compounds were identified, which is far more than previously reported.

Summary: Plasma-based ambient desorption/ionization sources often use helium as the primary discharge gas, but studies show advantages of mixed-gas plasmas. Adding H-2 to helium can decrease reagent-ion signals while preserving analyte-ion signals. Nitrogen addition increases negative reagent ions for enhanced ion signal of specific compounds. Various molecular gases impact emission characteristics and plasma parameters in mixed-gas systems.

Summary: Nanotechnology has opened a new frontier in the food industry by providing new ways of controlling and structuring products with greater market value, especially in areas such as food processing, preservation, and packaging. Macroalgae have been recognized as a potential source of secondary metabolites, such as phenolic compounds, pigments, and polysaccharides, which can be used for biosynthesis of metal nanoparticles (NPs). These biosynthesized metal NPs derived from macroalgae show advantages in terms of cost, production time, and biocompatibility, making them suitable for various applications in the food industry, such as nanoencapsulation, nanocomposites, and biosensors. However, the potential toxicity of metal NPs should be considered, and applicable regulations need to ensure their safe use.

Summary: Liver disease patients, especially those with surgically or spontaneously induced portosystemic shunts, can accumulate toxic substances, including manganese, in the brain, leading to acquired hepatocerebral degeneration (AHD). This study examined the levels of trace elements in AHD patients before and after liver transplantation (LT), finding imbalances in several trace elements and an improvement in neurological symptoms and inflammation after LT. These changes in trace element levels may contribute to the pathophysiology and symptomatology of AHD.

Summary: The present study demonstrated the potential of Chamaerops humilis extracts as food preservatives based on their antifungal, antiaflatoxin, and antioxidant efficacy. Molds isolated from peanuts were identified as Aspergillus, Penicillium sp., Fusarium sp., and Alternaria sp. The extracts effectively inhibited the growth and aflatoxin production of A. flavus at lower concentrations. These findings suggest that C. humilis extracts can be utilized as plant-based preservative food additives.

Summary: Polyhydroxy flavonols are easily degraded during thermal processing. This study used UPLC-Q-tof-MS/MS to investigate the stability of dietary polyhydroxy flavonols, including myricetin, kaempferol, galangin, fisetin, myricitrin, quercitrin, and rutin, in boiling water. The degradation of flavonols mainly resulted from the opening of the heterocyclic ring C to form simpler aromatic compounds. The degradation products included 1,3,5-benzenetriol, 3,4,5-trihydroxybenzoic acid, 2,4,6-trihydroxybenzoic acid, and 2,4,6-trihydroxybenzaldehyde, among others. The presence of glycosides in myricitrin slightly affected its stability, while the glycosides in rutin and quercitrin significantly improved their stability in water. During boiling, flavonols underwent various chemical reactions, such as hydroxylation, dehydroxylation, deglycosidation, deprotonation, and C-ring cleavage.
