Summary: In this study, changes in volatile organic compounds (VOCs) in Zhenyuan Daocai at different storage durations were analyzed. Various methods including electronic tongue (E-tongue), electronic nose (E-nose), and gas chromatography-ion mobility spectrometry (GC-IMS) were used. The results showed that the VOCs in Zhenyuan Daocai originated from raw materials and processing, and different compounds were responsible for different flavors. Furthermore, the characteristic VOCs changed after different durations of storage, contributing to floral, fruity, almond, roasted meat, fried coffee, and apple flavors.

Summary: The volatile metabolites and aroma of black tea undergo significant changes during storage, with certain compounds decreasing while others increasing. Linalool and beta-ionone contribute to the sweet and floral aromas of fresh and aged black tea, respectively, while isovaleric acid and hexanoic acid are responsible for the sour odor of aged black tea. The monoterpene biosynthesis and secondary metabolic biosynthesis pathways are likely crucial in driving these changes. This study provides theoretical support for understanding the aroma quality changes in black tea during storage.

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: This study investigated the effects of exogenous sucrose on monoterpene metabolism in Muscat Hamburg grape berries through transcriptomics and metabolomics. The results showed that sucrose application induced the accumulation of monoterpenes at harvest, with significant differential gene expression between control and treatment groups. Weighted gene correlation network analysis revealed a module likely correlated with monoterpene metabolism, providing new insights into the regulation of monoterpene biosynthesis in grape berries under exogenous sucrose.

Summary: In this study, nitrogen-doped biochar from herb residue was fabricated and used for peroxymonosulfate activation. The influence of nitrogen doping was explored through characterization and density-functional theory (DFT) studies. The nonradical singlet oxygen (1O2) was identified as the main reactive oxidative species, with pyridinic-N playing a pivotal role in the 1O2-dominated pathway. Three degradation pathways were proposed based on identified intermediates. Batch experiments confirmed the excellent catalytic performance and reusability of nitrogen-doped biochar. The proposed strategy provides a feasible approach for biochar synthesis and promotes its application in water purification.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
