Summary: In this study, a suspect screening workflow combined with a semi-quantification method was used to investigate the metabolites of DiPGDB and TBTM in human urine samples collected during winter and summer. Several metabolites were identified, and the DiPGDB-M310, DiPGDB-M194, and TBTM-M498 were suggested as potential biomarkers for assessing human exposure to DiPGDB and TBTM. The semi-quantification method is valuable for studies that lack analytical standards.

Summary: Aloe vera, a well-known medicinal plant in the Liliaceae family, was extracted via microwave-assisted extraction (MAE) to determine yield, total phenolic content (TPC), and total saponin content (TSC). LC-QTOF-MS analysis identified 32 phenolics and 29 saponin compounds in the extract, including steroid and triterpenoid saponins. The optimal MAE conditions resulted in a yield of 36.17%, with TPC and TSC levels of 73.05 mg GAE/g d.w and 65.89 mg OAE/g d.w, respectively.

Summary: One of the nutritional benefits of olive oil is its high content of monounsaturated fatty acids (MUFAs). We studied the fatty acids composition of virgin olive oil samples obtained from different cultivars over multiple crop seasons. The cultivars were categorized into two groups based on their MUFAs content. We also found that the fatty acids profile can be influenced by the climate conditions, with reduced precipitation leading to a decrease in MUFAs and an increase in SFAs/PUFAs concentrations.

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.
