Summary: Wheat is a major staple crop for a significant portion of the world's population, providing calories in the form of starch. Protein in wheat, particularly the proteinaceous alpha-amylase inhibitors, can reduce starch digestion, even after gastric proteolysis. The rate and extent of starch digestion can be altered by pepsin pre-digestion. Soluble proteinaceous alpha-amylase inhibitors present in wheat can escape gastric digestion and significantly contribute to reducing starch digestion in the small intestine.

Summary: The study demonstrates that Bacillus natto 16 can effectively remove deoxynivalenol from wheat flour and act as a detoxifying microbe. The removal process involves adsorption and biodegradation, with the components showing different effects in simulated gastric and intestinal fluids. This research provides a theoretical basis for the further development and application of Bacillus natto 16.

Summary: The substitution of wheat flour with quinoa flour can decrease the cooking time and iodine contrast index of noodles, increase the hardness of noodles, but has no effect on cooking loss. Substitution with quinoa whole flour decreases the protein digestibility and reducing sugar released during starch digestion. The sensory indicators of noodles are better when the substitution level of quinoa flour is <= 20%.

Summary: The aim of this study was to investigate the effect of sprouted oats substitutions on the in vitro digestibility of starch in wheat bread. The study found that polyphenols and gamma-aminobutyric acid increased, while starch and beta-glucan content gradually decreased in wheat bread enriched with 20% sprouted oat flour. The specific volume of the mixed bread reached its maximum after sprouting for 72 hours. The microstructure revealed that small type B wheat starch and oat starch were wrapped in protein-beta-glucan complexes after baking. This study suggests that properly sprouting has the potential to obtain nutritional bread with low starch digestibility.

Summary: Heat treatment is a pre-processing step that beneficially changes the starch properties of wheat flour to enhance its utilization in the food industry. It leads to changes in the chemical, structural, and functional properties of starch and gluten proteins, which influence the properties of the flour and the eating qualities of wheat-based products.

Summary: The study found that the dry heat treatment temperature has significant effects on the structure of wheat flour, bread texture, and starch digestibility. Higher temperatures decrease hydrated starch structures, increase crystallinity, and impact gluten secondary structure. High treatment temperatures result in reduced rapidly digestible starch and increased slowly digestible starch fractions.

Summary: In this study, the impact of feedstock-to-inoculum ratio in dry anaerobic digestion of Hura crepitans leaves was evaluated. The best F/I ratio and biogas production of the digesters were determined. It was found that early start-up and biodegradability constants were positively correlated with biogas production. Logistic and Gompertz models performed better in the kinetic analysis.

Summary: Enzymes play a crucial role as biological catalysts in accelerating biochemical reactions in living organisms. This study proposes a convenient method for monitoring enzymatic catalytic processes using native top-down mass spectrometry. By exploring the heterogeneity of the chymotrypsin sample and using tandem mass spectrometry, the researchers were able to monitor covalent and noncovalent enzymatic complexes, substrates, and products during catalysis. The results demonstrate that this method has the potential to be a promising tool for characterizing biocatalysts.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: The study developed a split aptamer-based sandwich-type ratiometric biosensor for the detection of 17 beta-estradiol (E2) using photoelectrochemical and electrochemical assays. The biosensor utilized split aptamer fragments to recognize E2 and trigger a hybridization chain reaction, resulting in the production of double-stranded DNA labeled with CdTe quantum dots. This DNA complex was able to sensitize CdTe quantum dots and generate response signals for E2 detection. The developed biosensor demonstrated high sensitivity and accuracy with two linear ranges and low detection limits.
