Summary: A strategy using microwave-induced combustion (MIC) and ion chromatography coupled to mass spectrometry (IC-MS) was proposed for the determination of bromine and iodine bioaccessibility from edible seaweeds after in vitro digestion. The concentrations of bromine and iodine in edible seaweeds using the proposed methods were comparable to those obtained using conventional methods. Trueness was assessed by recovery experiments and the results showed good accuracy. MIC was proposed as a sample preparation method for bioaccessible and residual fractions.

Summary: In recent years, microwave induced plasma optical emission spectrometry (MIP-OES) has gained attention as a cost-effective alternative to inductively coupled plasma-based techniques. However, the presence of easily ionizable elements poses a challenge to MIP-OES due to severe matrix effects. This study aimed to evaluate the feasibility of using MIP-OES in elemental bioavailability studies in soils and sediments.

Summary: In this study, high purity graphite was effectively digested using a single method, allowing for the determination of halogens using multiple techniques. The microwave-induced self-ignition (MISI) system combined with pressurized oxygen enabled rapid digestion of carbon-based materials and accurate determination of halogens. This method eliminates the need for additional ignition aids and utilizes a diluted absorbing solution with low blank values.

Summary: Microwave processing is a fast, safe, efficient, and environmentally friendly method for reducing anti-nutritional factors in edible grains. The power and duration of microwave processing significantly affect the inactivation of anti-nutritional factors and require critical evaluation for effective application. Heat labile anti-nutritional factors can be reduced through microwave heating due to degradation and formation of insoluble complexes.

Summary: This study analysed the migration of BPA in coffee from different qualities of polycarbonate microwaveable cups using UHPLC. The results showed that BPA migration was minimal in good-quality cups, but increased significantly in poor-quality cups with longer contact duration. The leaching process of BPA was enhanced during microwave heating due to high temperatures reached in a short time.

Summary: This study investigated the concentrations of chemical elements in mud, fish, and water samples from Governador Valadares city in Brazil after a major environmental disaster. The results showed that the gills of fish had higher bioaccumulation of elements compared to muscle tissue, and the daily intake of fish in these locations did not pose health risks. Therefore, it suggests that fish consumption of 60 grams per day in these areas is safe.

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.
