Summary: Surface-enhanced Raman spectroscopy (SERS) increases Raman signal using nanostructures, more suitable for detection than quantification due to signal complexity and control parameters. This study aimed to develop discriminative and quantitative analysis based on optimized parameters, achieving excellent separation between two similar neurotransmitters. The short-term evolution of Raman signal intensity coupled with chemometric tools helped identify outliers, with multivariate analysis showing superiority after logarithmic transformation. Quantitative analysis developed robust quantification models with ultrasensitive detection using a handheld Raman spectrometer.

Summary: In this study, gold nanoparticles with a diameter of 67 +/- 6 nm supported by vertically aligned shell-insulated silicon nanocones were formed for ultralow variance SERS. The morphology and optical properties of the substrates were assessed through various characterization techniques. The SERS activity was measured and compared to other lithographically derived assemblies. The low variance of our substrates makes them suitable for many potential SERS applications.

Summary: An improved understanding of bacterial inactivation mechanisms was obtained by evaluating bacterial response to different inactivation methods using surface-enhanced Raman spectroscopy (SERS). The results showed that changes in the SERS signal were closely related to cellular disruption, and the changes in cellular morphology after inactivation cannot be ignored. Different methods, such as heat treatment, UV254 treatment, and UV254/chlorine treatment, led to severe membrane disruption, resulting in increased peak intensities. However, ethanol treatment resulted in intact cell morphologies and minimal changes in the SERS spectra. The main changes observed during inactivation were related to nucleic acids, and the peaks associated with nucleic acids showed significant variations. Carbohydrates and proteins on the cell membrane were denatured or lost after chlorine treatment, leading to a decrease in related peak intensities. The method was also found to be applicable to different bacterial strains and water matrices.

Summary: This study presents a simple approach using a flexible surface-enhanced Raman spectroscopy (SERS) substrate for rapid and on-site detection of pesticide residues. The prepared substrate showed high SERS activity, good precision, and stability after optimization. It achieved a linear relationship between characteristic SERS bands and concentrations for target pesticides, with low limits of detection. The substrate can be used for simultaneous identification of multiple pesticides. Overall, this method simplifies the pre-treatment procedure and serves as a promising analytical tool for pesticide screening.

Summary: Research shows that plasmonic supercrystals, with a high density of hotspots, are an excellent platform for enhancing vibrational spectra by increasing the cross section of Raman scattering and infrared absorption. The study demonstrates that the intensity of surface-enhanced Raman scattering inside the crystal is uniform and predictable, with supercrystal polaritons inducing resonances in the enhanced cross section for both Raman scattering and infrared absorption. The enhancement of infrared absorption within supercrystals is attributed to the combined effects of hotspot formation and the excitation of standing polariton waves.

Summary: This study aimed to investigate the influence of alkaline salts on the formation of protein-bound N-epsilon-carboxymethyllysine (CML) and N-epsilon-carboxyethyllysine (CEL) in raw minced pork during cold storage. The results showed that the storage duration significantly affected the levels of lipid oxidation, protein oxidation, and protein hydrolysis in minced pork, but had minimal impact on CML and CEL levels. Interestingly, the addition of alkaline salts increased the levels of CEL, but did not affect CML levels. These findings suggest that the promoting effects of alkaline salts on CEL formation are not directly related to their effects on pH, lipid oxidation, protein oxidation, and protein hydrolysis in minced pork.

Summary: Lipid oxidation, protein degradation, and AGEs formation increased during freezing-thawing cycles and heat treatment. Freezing-thawing treatment accelerated the heat-induced increase of AGEs in surimi products. Correlation analysis showed that lipid oxidation and protein degradation promoted the chemical synthesis of AGEs, while Schiff base oxidation likely occurred only under thermal treatment.

Summary: The study analyzed the variations in levels of free and protein-bound N-epsilon-carboxymethyl-lysine (CML) and N-epsilon-carboxyethyl-lysine (CEL) in different types of pork meat and organs. The results showed that the levels of free CML and CEL were higher in raw kidneys compared to tenderloin, hearts, and livers. Furthermore, the protein-bound CML and CEL levels in livers and hearts were significantly higher than in tenderloin. However, after heating, the levels of protein-bound CML and CEL were relatively lower in livers and kidneys compared to tenderloin and hearts.

Summary: This study evaluated the effects of lactic acid, citric acid, and malic acid on the rheological properties of fish gelatin obtained from tilapia skin. The addition of these acids weakened the gel strength and rheological properties, with higher concentrations having a more significant effect. Lactic acid had a lesser effect compared to citric acid and malic acid, which was consistent with their effects on pH.

Summary: This study investigated the impact of citric or acetic acid addition and storage duration on the formation of two potentially hazardous AGEs in pork during heat treatment. The results showed that longer storage time led to higher levels of AGE production during heating. Adding acid to pork significantly reduced the formation of CML/CEL. However, the marinating time with acid did not significantly affect the inhibition effect on heat-induced formation of CML/CEL.

Summary: Concerns about food safety have been raised due to improper use of chemicals in aquaculture, particularly malachite green (MG) which can have negative impacts on the environment and public health. Surface-enhanced Raman scattering (SERS) platforms coupled with reusable SERS substrates are used for rapid analysis of MG residues in food. In this study, a novel SERS substrate combining metal-organic framework material (MIL-100(Fe)) and Au NPs was prepared, showing high sensitivity and recyclability. The sensor successfully detected trace amounts of MG in fish pond water and showed great potential for food contamination monitoring.

Summary: The study investigated the effects of freeze-thaw cycles and subsequent heating on protein degradation, oxidation, and advanced glycation end-products (AGEs) in ground pork supplemented with sucrose. Results showed that an increase in freeze-thaw cycles promoted protein degradation and oxidation. The addition of sucrose further enhanced the production of TCA-soluble peptides, Schiff bases, and CEL, leading to higher levels of these compounds in the ground pork compared to the blank groups. Subsequent heating resulted in an increase in Schiff bases and a decrease in GO and MGO, while CML and CEL levels increased.

Summary: This study conducted GC-MS analysis on the characteristic volatiles related to the quality deterioration of reheated pork. The concentrations of selected volatiles in reheated pork increased with the storage time of the precooked counterparts, with hexanal showing the highest increase rate. Clustering analysis of these volatiles revealed their formation pathways tied to lipid autooxidation. This simple approach provides a new possibility for standardizing volatile analysis of reheated precooked meats.
