Summary: Ethylenediurea (EDU) is a potential protectant for crops against surface ozone (O-3) phytotoxicity. A field study on rice plants showed that EDU reduced grain nitrogen concentrations (GN) by 3.81%, suggesting that ambient O-3 affects grain quality. The effects of EDU on GN were rice type dependent, with decreases of -0.43%, -0.72%, and increases of 1.19% in indica, japonica, and hybrid rice, respectively. EDU promotes sink in rice and increases grain yield, but indica and japonica cultivars have insufficient nitrogen allocation to maintain GN. The results highlight the possibility of adjusting grain quality by EDU in response to surface O-3 pollution, through cultivar selection and agricultural management.

Summary: Gluten-free beer is produced by adding an enzyme-enriched malt extract to gluten-containing barley malt wort for patients with celiac disease. The treatment reduces certain compounds and affects foam, amino nitrogen, aging stability, and color in the beer. Analysis of aging components suggests an increase in heating compounds and aging indicators. The presence of long-chain free fatty acids negatively correlates with esters, and increasing their concentration may enhance the aroma of gluten-free beer.

Summary: 3-dimensional printing is a novel processing method that can be used for designing and manipulating food textures. This study focused on the deformation behavior of 3D printed closed-cell starch-based foams and controlled the foam's deformation behavior by adjusting the distribution of bubbles. The results showed that stress relaxation depends solely on cell wall properties, while different stress-strain regimes rely on bubble size and distribution. Precisely controlling the large deformation behavior of foods using 3D printing is challenging due to the superposition of structural and geometrical dependencies.

Summary: For industrial processes, it is crucial to have a fast, precise, and reliable method for determining the physiological state, particularly viability, of yeast cells. This study examined the impact of magnetic nanoparticles (MNPs) on yeast cell viability and the assay itself, testing two types of yeast cells. The results showed that traditional colorimetric staining was only reliable for cells with good viability, while fluorescence microscopy and flow cytometry-based assays demonstrated high precision and reliability in determining viability, even in the presence of MNPs. Moreover, the study revealed a non-linear relationship between membrane fluidity and yeast cell viability. The use of CFDA and membrane fluidity provided accurate results for both yeast types, allowing for efficient viability determination in experiments involving yeast cell manipulation or separation using MNPs.

Summary: Despite the wide use of yeast in various industries, the impact of viability and age distribution on cultivation performance is not fully understood. In this study, a magnetic batch separation method was used to isolate daughter and mother cells from a heterogeneous culture, revealing that low viability cultures with high daughter cell content perform similarly to high viability cultures with low daughter cell content. The separated daughter cells showed higher growth rates than mother cells in both aerobic and anaerobic conditions. These findings highlight the importance of viability and age in yeast cultivation and lay the foundation for improving yeast-based processes.

Summary: Brewing experiments were conducted to assess the impact of black-colored grain on Alternaria mycotoxin concentrations throughout the brewing process. The concentrations of 13 different Alternaria mycotoxins were analyzed in each step using liquid chromatography-tandem mass spectrometry, and the toxin concentrations were balanced over the entire process. The results showed that TeA was the only toxin to migrate into the final beer, while other toxins were mainly found in the spent grains. This study suggests that optical sorting of malt batches can be a useful tool for preventing elevated mycotoxin concentrations in the malting and brewing industry.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: Specialty malt beers are brewed to provide unique flavor and color, which are influenced by the chemical compositions of special malts. Brewing trials showed that kilned specialty malts have an impact on the properties of wort and beer. The study found that the boiling process led to significant losses of KSM odorant markers, and that Maillard aldehydes derived from KSM played a major role in the sensory profile of the beers. The research also suggested that the brewing process has a high influence on the formation of KSM odorants and the aroma composition of the final beer.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
