Summary: Two reversed-phase HPLC methods were compared for molecular analysis of dissolved free monosaccharides in seawater, with the 2-amino benzamide method showing better results. A total of 12 monosaccharides could be quantified with detection limits between 1.2 and 11 nM and good repeatability. Additional studies using different column polarities may lead to even higher sensitivity and detection of more monosaccharides.

Summary: Gas chromatography is a widely used analytical technique, but not all analytes can be directly analyzed. Analytical derivatization, such as injector port derivatization, is often required to improve the suitability of analytes for gas chromatographic analysis. This technique is easy to use, efficient, and requires fewer hazardous chemicals.

Summary: Algal alginates are important resources for industrial materials, and the ratio of D-mannuronate to L-guluronate affects the physical properties of polysaccharide preparations and gels. The percentage and configuration of each uronic acid oligomer also have an impact on biological and physiochemical properties. Therefore, a highly sensitive analytical technique for uronic acids and their oligomers is needed for both biological studies and quality control in manufacturing.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
