Summary: In this report, a SERS substrate named MIL-101-MA@Ag is developed by combining the enrichment ability of MIL-101(Cr) and the local surface plasma resonance (LSPR) of silver nanoparticles, which can produce high-density and uniformly distributed hot spots. The substrate has demonstrated good SERS activity for the detection of malachite green (MG) and crystal violet (CV) with low detection limits. It has also been successfully applied to detect MG and CV in tilapia with high recovery rate and relatively low standard deviation.

Summary: This study investigates the influence of energy levels and alignments of molecular orbitals on the charge transfer process and surface-enhanced Raman scattering (SERS) phenomenon. Experimental results show that the detection of antibiotics on electrochemically synthesized colloidal silver nanoparticles (e-AgNPs) as substrates differs due to the different energy levels of the antibiotics. The hypothesis is confirmed by testing other organic compounds. The study reveals a clear correlation between the energy level of analytes and their SERS signals.

Summary: A new type of supramolecular solvent (SUPRAS) with high density, based on hexafluorobutanol (HFB) primary alcohol ethoxylate (AEO) was prepared for the first time. The SUPARS formed from MOA-3 and HFB showed better extraction efficiency compared to other SUPRASs. Parameters affecting the extraction recovery of target analytes were investigated and optimized. The proposed method is simple, fast, and green, and can be used for the analysis of target analytes in solid samples.

Summary: Urchin-like gold nanoparticles (ULGNs) with hollow structure and tunable branches were successfully prepared by the one-pot method. The number and length of branches on ULGNs increased with the increase of ascorbic acid, while the size of nanoparticles and number of branches decreased with the increase of silver nitrate. By partially exposing the ULGNs@Ag branches beyond the silver layer, the best SERS properties were achieved and used for the detection of malachite green, providing a new approach to food safety testing.

Summary: In this work, Au nanowires array was prepared through a seed-mediated soft template growth method, and modified with silver nanoparticles to form Ag/Au nanowires array as a SERS substrate. The SERS substrate showed high sensitivity, excellent signal homogeneity, and good stability, with a low detection limit for malachite green in water. Moreover, the substrate can be recycled due to the removal of adsorbed molecules without affecting the SERS performance.

Summary: In order to improve the detection performance of surface-enhanced Raman scattering (SERS), a low-cost Au@Ag nanorods (Au@Ag NRs) substrate with a good SERS enhancement effect was developed and applied to the detection of malachite green (MG) in aquaculture water and crayfish.

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: The aim of this research was to determine the effects of acetic acid, malic acid, and citric acid on the stress-strain responses of fish gelatin gels under compression. The acids weakened the gel structures and increased the strain hardening capacity of the gels. The pH changes alone could not fully explain the effects of the acid ions on the gel structure.

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.
