Summary: Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry and headspace gas chromatography-ion mobility spectrometry were used to analyze the volatile organic compounds from chilled chicken contaminated with Staphylococcus aureus during early storage. Differential metabolites and their possible biotransformation pathways were analyzed using the KEGG database. Orthogonal partial least squares discriminant analysis was applied to identify biomarkers associated with the early stage of chicken meat contamination with S. aureus.

Summary: The flavor substances in different stages of Longpai soy sauce moromi fermentation were analyzed by HS-GC-IMS combined GC x GC-ToF-MS. A total of 374 VOCs were detected, with alcohols and esters being the most abundant. During the early stage, alcohols and aldehydes were the main flavor compounds. The content of esters, pyrazines, furans, and S-containing compounds improved with continuous fermentation. Cluster and PCA analysis showed that 63 VOCs were regarded as marker VOCs for soy sauce in different fermentation stages. Certain compounds, such as alcohols, 1-butanol, and 3-methyl-2-butenal, provided fruity and mellow aroma in the early stage, while caramel-like, malty, and sweet aroma were enhanced by compounds like 3-methyl-2(5H)-furanone, 3-methylbutanol, methional, and acetyl valeryl in the middle stage. Additionally, furfuryl alcohol, 2(5H)-furanone, methyl cyclopentenolone, and 2-Ethyl-6-methylpyrazine could serve as marker VOCs of matured Longpai soy sauce.

Summary: Indoor air quality in libraries has a direct impact on human health and is influenced by volatile organic compounds (VOCs) emitted from aging print material. A study using HS-SPME-GC/MS analysis identified different VOC emissions from old and new books, with alcohols and ethers predominantly found in old books, and ketones and aldehydes in new books. Chemometric analysis and gaseous markers allowed for the classification of books into three age groups: very old, old, and modern. The measured concentrations of selected VOCs were below guidelines set for similar environments. The non-invasive, green analytical methodology can assist in evaluating IAQ, degradation, and book restoration in libraries.

Summary: The physicochemical and nutritional properties of three varieties of coconut water at two maturity stages were investigated. The properties of the water changed significantly with maturity rather than variety. Phenolic compounds and volatile organic compounds (VOCs) were identified and different varieties showed variations in phenolic composition and VOCs. These findings provide useful insights for selecting raw materials of coconut water for different industrial purposes.

Summary: We investigated the influence of heat treatment on the volatile organic compounds (VOCs) of milk using various technologies. The results showed that heat treatment at 65 degrees C for 30 min preserved the original taste of milk, while treatment at 135 degrees C significantly altered the overall flavor. Different processing techniques also affected taste presentation, with the sweetness, saltiness, and bitterness of the milk being influenced by the temperature of the heat treatment. Additionally, the composition of VOCs in milk changed with heat treatment, with acid compounds decreasing and ketones, esters, and hydrocarbons increasing. Our study provides new evidence for understanding the impact of processing on milk VOCs and insights into quality control during milk production.

Summary: This study used HS-GC-IMS to detect the VOCs of C. fimbriata-infected sweet potatoes in the early stages. A total of 55 VOCs were identified, including aldehydes, alcohols, esters, ketones, and others. The changes in VOCs were closely related to the content of MDA, starch, pyruvate, and the activities of LOX, PDC, ADH, and PAL. PCA and OPLS-DA showed that sweet potatoes had a good discrimination effect from 0 to 72 h. Twenty-five differential VOCs could be used as early-stage characteristic compounds of C. fimbriata-infected sweet potatoes for early disease monitoring.

Summary: The volatile organic compounds (VOCs) produced during meat storage were identified using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) after inoculating the bacteria into the substrate. The concentrations of alcohols and organic acids were significantly higher in samples inoculated with bacteria. Certain VOCs were closely related to the metabolic activity of the inoculated bacterial strains. These compounds are potentially important for predicting deterioration of smoked bacon.

Summary: This study identified cultivar-specific metabolic fingerprints of volatile organic compounds in cloudy apple juices from 47 true-to-type apple cultivars in South Tyrol, Italy. Despite the lack of clear separation of cultivar classes in principal component analysis and hierarchical cluster analysis, certain scab-resistant and red-fleshed cultivars with VOC profiles similar to established commercial cultivars were identified, suggesting potential for substituting current cultivars with more sustainable ones. The study supports a knowledge-driven selection of apple cultivars for specific consumer preferences and highlights the biodiversity of apples across old local and more recent cultivars.

Summary: A series of poly(ether sulfone) random copolymers with different loading of diphenolic acid (DPA) units were synthesized and their thermal behavior was comprehensively studied. The copolymers were synthesized from various amounts of 4,4'-dihydroxydiphenylsulfone, DPA, and 4,4'-dichlorodiphenyl sulfone. The degradation activation energy (E-a) was determined and compared with previous studies. The thermal stability evaluation showed good performance, but caution is needed regarding the percentage of pendant carboxylic acid groups, as deterioration of physical properties was observed at 30% content.

Summary: Conventional drug delivery has limitations in terms of rapid drug release and short duration of therapeutic drug concentrations. Prolonged drug release can be achieved by modifying the carrier in a drug delivery system. In this study, poly (ether ether ketone) was chosen as a suitable carrier after controlled sulfonation to overcome its hydrophobicity.

Summary: In this study, antibacterial polymer blends based on PVC and SEBS loaded with an IL were produced and characterized. The IL release behavior, as well as the thermo-mechanical properties, surface morphology, and wettability of the blends were evaluated. The antibacterial activity of the blends against S. epidermidis and E. coli was also tested, and the results showed promising performance at low IL concentrations. These findings suggest the potential versatile use of these antimicrobial polymers in various fields.

Summary: The importance of lead analysis in environmental matrices is increasing due to human-induced spread of toxic species in nature. A new dry approach for lead detection and measurement is proposed, which involves capturing lead from a liquid solution using a solid sponge and quantifying it through X-ray analyses. Gig-lox TiO2 layers with a branched multi-porosity spongy structure were used to capture lead atoms in a liquid environment. The method is based on the relationship between the electronic density of the solid sponge and the critical angle for total reflection of X-rays.

Summary: With the projected rapid growth of the market uptake of perovskite solar cells (PSCs), the use of this clean energy technology will play a crucial role in reducing the global carbon footprint. However, the presence of toxic lead (Pb) poses a major barrier to its full commercialization. Researchers have demonstrated that the application of a transparent titanium dioxide (TiO2) sponge can effectively prevent Pb leakage, leading to a more sustainable solution and accelerated practical applications.
