Summary: This study explores the feasibility of ink diffusion based on Raman spectra monitoring and identifies ink types using OPLS-DA multivariate modeling. The kinetics of ink diffusion can be elucidated by the interplay of chromatographic effects and diffusion equilibrium. The OPLS-DA model demonstrated 100% accuracy in differentiating between all types of stamp inks, affirming the significant potential of Raman spectroscopy for forensic science applications.

Summary: In this study, pre-enzymolysis followed by lactic acid bacteria fermentation was used to improve the insufficient taste and imbalanced aroma of enzyme-modified cheese (EMC). The strategy generated taste compounds and released flavor precursors, leading to significant increases in free amino acid (FAA) and free fatty acid (FFA) flavor precursors compared to the control. Pre-proteolysis accelerated fermentation and increased the production of specific aromatic compounds. Pre-lipolysis released large amounts of methyl ketones and fatty acids, but flavor imbalance was improved during fermentation. These findings provide practical guidance for producing EMC with authentic Cheddar flavor and offer new avenues for flavor improvement.

Summary: This study investigated the effects of different cooking modes and stewing times on the chemical compositions, sensory quality, and flavor substances in chicken soup with added Clitocybe squamulose. The results showed that chicken soup cooked in a ceramic pot had higher amounts of soluble solid matter, total sugar, crude protein, and 5'-nucleotides compared to soup cooked in an electrical ceramic stewpot and a stainless-steel pot. Gas chromatography-mass spectrometry analysis revealed several volatile flavor compounds in the ceramic pot soup, with hexanal, (E,E)-2,4-decadienal, and 3-methyl-hexadecane being the most abundant. Sensory evaluation demonstrated that the ceramic pot soup had higher scores for aroma, taste, and overall acceptability. These findings suggest that cooking chicken soup in a ceramic pot may be the best option for improving its quality and flavor.

Summary: This study used Surface-enhanced Raman spectroscopy (SERS) to differentiate between gallbladder (GB) stones and GB polyps in serum samples. The sensitivity, specificity, and area under curve (AUC) values of the diagnostic results reached high levels, demonstrating the potential of this method as a quick and accurate means of diagnosing GB diseases. The combination of serum SERS spectra with orthogonal partial least squares discriminant analysis (OPLS-DA) provided accurate and rapid identification of GB stones and GB polyps.

Summary: This paper proposes a novel adaptive joint clustering algorithm that combines unsupervised discrete orthogonal least squares discriminant analysis (DOLSDA) and discrete spectral clustering (DSC) with adaptive neighbors and side information. The algorithm leverages both cluster and pairwise data structures by embedding DSC with the discrete kernel OLSDA (DKOLSDA) clustering. An increment scheme is developed to achieve the optimal spectral rotation for the approximate solution to the predicted indicator.

Summary: This study compared the metabolomic changes of human urine and plasma to determine which one can be used as the best tool to identify metabolomic profiling and novel biomarkers associated with the effects of UV radiation. The data modeling of urine samples showed clear separation between pre- and post-exposure to UV, while plasma samples did not. Metabolomic analysis revealed changes in multiple metabolic pathways, including amino acids, lipids, peptides, xenobiotics biodegradation, carbohydrates, nucleotides, co-factors, and vitamins. In conclusion, metabolomic screening of urine samples may be a better tool than plasma samples to predict metabolomic changes due to UV exposure.

Summary: This study investigated the use of ice glazing containing D-sodium erythorbate (DSE) and vacuum packaging to maintain the quality of large yellow croaker during frozen storage. The results showed that vacuum packaging effectively inhibited ice crystal growth and minimized water loss, while the combination of vacuum packaging and 0.3% DSE-infused ice glazing maintained freshness indicators at low levels throughout the 300-day storage period. This combination was considered the most effective in preserving the quality of the fish.

Summary: This study investigated the transport and hypoglycemic effects of phenolics in mulberry leaves using an in vitro digestion model. The results showed that digested phenolics had higher absorbability and could inhibit glucose digestion and absorption. Phenolics also regulated glucose metabolism. Luteoforol and p-coumaric acid were found to be the primary phenolics strongly correlated with the hypoglycemic ability of mulberry leaves.
