Summary: The trend of cold brew coffee (CBC) is increasing globally, but there is limited research on this popular beverage. This study aimed to investigate the effects of brewing conditions on the physicochemical properties of CBC and compare it with coffee brewed by the French Press method. The results showed that water temperature, coffee-to-water ratio, and coffee mesh size significantly influenced the total dissolved solids (TDS) of CBC. At similar TDS, CBC had higher caffeine content, volatile compounds, and organic acids compared to the French Press coffee.

Summary: This study highlights the effectiveness of rice husk nanoadsorbent RHN in removing Zn (II) from aqueous solutions. A statistical technique, central composite design of response surface methodology, was used to investigate the removal process by varying adsorption parameters. The study found that Zn (II) removal was most effective at pH 6, dose of 0.8 g/L, and metal ion concentration of 15 mg/L. The adsorption process was found to be well-fitted by Langmuir isotherm model and pseudo-second order kinetic model. The study also analyzed the regeneration of the RHN adsorbent for three successive cycles.

Summary: This study employs ANSYS Fluent 2022 R1 to visualize the airborne transmission of pathogens in indoor spaces under different environmental conditions. Five indoor parameters are studied, including wind velocity, air temperature, relative humidity, particle residence time, and physical distancing. Simulation-based experiments reveal the optimum indoor condition for reducing human-to-human airborne transmission. Higher relative humidity results in larger particle diameter, while lower humidity leads to particle shrinkage. Furthermore, longer distances between individuals result in lower particle deposition and prolonged exposure risk. This research is significant for enhancing safety and health judgement during a pandemic by identifying the optimal indoor conditions to minimize airborne transmission between individuals.

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.
