Summary: A novel genipin crosslinked calcium alginate/chitosan/polydopamine composite beads (g-Alg/CS/PDA) were synthesized for the removal of residual difenoconazole and nitenpyram during the clarification of apple juice. The adsorption parameters were optimized, and the adsorption behavior of beads was found to be heterogeneous, controlled by several factors. Hydrophobic and pi-pi conjugation interactions played a dominant role for the adsorption of difenoconazole, while hydrogen bonding and electrostatic interactions were the main factors for nitenpyram.

Summary: Simultaneous multiresidual pesticide analysis of saliva samples was conducted using scaled-down QuEChERS extraction with LC-MS/MS and GC-MS/MS. The optimized extraction procedure was applicable to 336 pesticides. The validated analytical method showed good performance in terms of LOQs, accuracy/precision values, and recovery results.

Summary: The study focused on the microbial diversity and key properties of Polish red wines produced by spontaneous fermentation. It identified the most abundant bacterial and yeast species in the wines from different vineyards and noted significant differences in antioxidant capacities and concentrations of glucose, fructose, and lactic acid. The findings highlighted the importance of indigenous strains for the development of unique local starter cultures and the production of wines with specific characteristics.

Summary: The research evaluated the effectiveness of nearly zero-energy building designs for energy-efficient wineries by monitoring temperature and humidity in 12 red wine aging rooms. Results show that zero-energy buildings can provide suitable conditions for wine aging, but there are notable differences in cost and effectiveness depending on the type of building.

Summary: Leafy vegetables, due to their inability to be peeled and their large leaf surface area, present a higher risk of retaining pesticide residues compared to other vegetables. This study is the first comparative study to investigate the effectiveness of different removal methods for pesticide residues on five leafy vegetables. The results highlight the importance of thoroughly washing leafy vegetables to reduce the intake of pesticide residues.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.

Summary: This study successfully discriminated the geographical origin and vintage of wines using an untargeted metabolomic approach based on LC-IM-QTOF-MS. Wines were well discriminated according to region and vintage with OPLS-DA. Differential metabolites were screened and used for wine region and vintage discrimination, achieving an accuracy over 84.2% in the external verification trial. LC-IM-QTOF-MS-based untargeted metabolomics was demonstrated to be a feasible tool for wine geographical origin and vintage discrimination.

Summary: The addition of chitosan led to a decrease in BSA reactive tannins in all wines, with this effect persisting even after oxidation. Wines previously treated with chitosan and oxidized showed a significant decrease in reactivity towards salivary proteins. Chitosan also resulted in lower formation of polymeric pigments in all wines.

Summary: This study examined the effect of cold plasma on the physicochemical and biological properties of red wine. The results showed that cold plasma treatment had minimal impact on the quality of red wine, with no significant changes in color and effective inhibition of microbial growth. This suggests that cold plasma has the potential to be an alternative method to replace potassium metabisulfite in wine production.

Summary: The aroma quality of wines is directly determined by grape volatile compounds. This study revealed that aroma maturity should be considered when determining grape harvest time. Monitoring several maturation indicators in four red wine grape varieties in Ningxia, China, it was found that the best aroma maturity time for the studied varieties was later than the sugars/acids ratio.

Summary: An analytical method was developed and optimized to determine the concentrations of aroma compounds related to the fruity aroma of red wines. Samples from different grape varieties were quantitatively analyzed, and the instrumental analysis revealed variations in the concentrations of quantified compounds among the wines. Both sensory profile results and instrumental analysis showed the potential positive contribution of non-ester compounds to the fruity expression of red wines.

Summary: In this study, an analytical method based on fluorescence spectroscopy and multivariate calibration was used to accurately determine the levels of catechins in wine samples. The incorporation of a pH gradient reaction mode improved the predictability and selectivity of catechin detection. The application of the MCR-ALS algorithm allowed for the resolution of systems and yielded satisfactory results, even in the presence of uncalibrated interferences.
