Summary: Young Riesling wines are enjoyed for their fruity and floral notes, while aged Riesling wines develop more robust flavors like maple and honey. A study identified 36 odorants in a 10-year-old Riesling wine, with some having high odor activity values. The findings provide insight for future research on the influence of aging on aroma chemistry in Riesling wines.

Summary: Experiments identified rotundone as the compound responsible for the spicy, woody, incense-like odor note in oak-aged spirits. Analysis showed that the content of rotundone increased with years of barrel aging, confirming its origin to be from oak. Odor-activity values comparison indicated the relative importance of rotundone in the overall flavor of oak-aged spirits.

Summary: Patients with birch pollinosis often have adverse reactions to fresh apples due to the similarity of allergens in birch and apples. A proteomics approach was developed to quantify the allergen Mal d 1 in apples. Marker peptides for different isoallergens of Mal d 1 were identified, and the isoallergen-specific content in different apple varieties was quantified.

Summary: The major off-flavor odorants of normal and lipoxygenase-lacking soy protein isolates were identified through sensory-directed flavor analysis. A total of 32 odor-active compounds were detected, and 19 of them were quantified. Hexanal and nonanal were found to dominate the off-flavor profile, followed by octanal, 1-hexanol, 1-octen-3-ol, 2-heptone, and benzaldehyde. The differences between NOR and LOX-lack SPIs were mainly attributed to reduced C6/C9 aldehydes and alcohols.

Summary: Recent studies have shown that liquid chromatography-mass spectrometry (LC-MS) can be used to quantitate aroma and taste compounds. This study aimed to demonstrate the broad application of this method by developing a stable isotope dilution analysis quantification method for key food odorants. The researchers established a quantification method for 20 key food odorants using LC-MS, with good precision and limits of quantitation. This work highlights the accurate analysis of a wide range of aroma compounds by LC-MS.

Summary: This pioneering investigation applied the accentuated cut edges (ACE) technique to Sauvignon blanc winemaking. ACE treatment resulted in significantly higher concentrations of varietal thiol precursors in juice compared to conventional crushing, with two-way or three-way interactions of yeast strain and malolactic fermentation affecting the wine data. ACE yielded wines with higher concentrations of 4-methyl-4-sulfanylpentan-2-one (4-MSP) and enantiomers of 3-sulfanylhexanol (3-SH) and 3-sulfanylhexyl acetate (3-SHA), which were also more abundant in phenolic compounds. Different yeast strains and MLF influenced the concentration of 3-SH, 3-SHA, and 4-MSP, as well as the sensory attributes of the wines.

Summary: It was found that Vitis vinifera L. cv Shiraz cannot synthesize 3-alkyl-2-methoxypyrazines (MPs) in its berries but can produce significant concentrations in its rachis. The study investigated the effect of different rootstocks on the concentrations of three specific MPs in the rachis of Shiraz bunches. The results showed that MP concentrations were influenced by vintage, rootstock, and region, with vine vigour positively correlated with the most abundant MP, IBMP.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
