Summary: This study described the development and optimization of a method for iodine speciation analysis in seaweed using HPLC-ICP-MS. The results showed a large variation in total iodine content among different seaweeds, with the highest levels in brown seaweed. Iodine speciation analysis revealed differences in the speciation profile of different seaweed types and identified six unknown iodine-containing species.

Summary: This study examines the availability of seaweed food products in the UK market from 2018 to 2021 and assesses their safety in terms of iodine exposure. The study shows a young and dynamic market, with a 2.3-fold increase in product availability since 2015. However, iodine content labeling remains uncommon and median iodine doses in a single serving exceed 400 μg in all years. Some products, particularly seaweed supplements, provide iodine doses above the tolerable upper limit.

Summary: The consumption of seaweed is increasing in the Western world and it may serve as a potential dietary iodine source. A study was conducted to compare the bioavailability of iodine from a meal consisting of sushi with nori and wakame seaweed salad to a potassium iodide reference supplement. The results showed that the bioavailability of iodine was higher from the supplement compared to the meal.

Summary: A new analytical technique combining protein precipitation, heating, lipid degreasing, and SPE procedures with HPLC-UV and HPLC-MS/MS has been developed for the determination of neotame in food samples. This method is suitable for high-protein, high-lipid, or gum-based solid samples. The HPLC-UV method had a limit of detection of 0.5 μg/mL, while the HPLC-MS/MS method had a limit of detection of 3.3 ng/mL. The technique was successfully applied to determine the neotame content in positive food samples.

Summary: In this study, gamma irradiated aqueous samples containing I-2 and I- were analyzed using two different methods with an UV-VIS spectrophotometer, which showed accuracy within 4% for both I-2 and total I measurements. The I-2 concentrations measured by the toluene extraction method were consistently lower compared to those measured by the equilibrium relationship method, indicating a potential loss during the toluene extraction step.

Summary: This study evaluated the behavior of radioactive iodine in nuclear power plant severe accident conditions by measuring the concentrations of volatile I-2 and non-volatile iodine formed by thermal and radiolytic decomposition of NaIO3. The calibration curves of I- concentrations in UV-VIS spectrophotometry were found to be unaffected by pH in the range of 3-13. ICP-MS was used to measure the non-volatile I concentration due to overlapping UV-VIS absorption spectra of IO3- and I- in the range of 190-275 nm.

Summary: The nature of the blue color in the iodine-starch reaction is still debated, but it is generally believed that the blue color comes from the charge-transfer between iodide ions and I-2 molecules inside the amylose helix. Experimental and computational studies suggest that the best candidate for the blue complex is an I-2-I-5-I-2 unit.

Summary: The behaviour and distribution of iodine in the environment is important in various scientific fields. A new method for measuring iodine species in low dissolved organic carbon waters is presented, which uses ion exchange chromatography with direct ultra-violet spectrophotometric detection and does not require sample pre-concentration. The method can quantitatively measure iodate, iodide, and dissolved organic iodine in different aqueous environments.

Summary: This study found that filamentous microalgae as a co-substrate for anaerobic digestion of pig manure can significantly improve methane yield, digestion kinetics, and digestate dewaterability. The best results were achieved at a mixing ratio of 1:1, enhancing energy conversion efficiency and reducing the lag time of AD. The presence of microalgae in the co-substrates also reduced the specific resistance to filtration of the digestate, making it easier for processing and valorisation.

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: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

Summary: Horse's milk, with its high nutritional value and low allergenic proteins, could be a substitute for cow's milk in infant consumption. A proteomic method was used to identify and compare milk fat globule membrane (MFGM) and whey proteins from different horse breeds. The study found differences in protein composition and functionality, which could support the development of formulas more suitable for human infants.

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.
