Fish skin collagen peptides (FSCP) are primarily sourced from fish processing by-products and exhibit notable bioactivity and superior functional characteristics. The effects of FSCP (0–2.0%, w/w, based on flour weight) on the structure, rheological properties, water distribution, and in vitro digestibility of starch within wheat dough during freezing were systematically investigated. The addition of FSCP reduced the R 1047/1022 ratio from 1.35 ± 0.26 to 0.99 ± 0.21 and relative crystallinity from 31.08 ± 0.56% to 25.21 ± 0.14%. Low-field nuclear magnetic resonance analysis demonstrated that FSCP inhibited water migration and reduced the proportion of free water, thereby restricting starch chain mobility. Correspondingly, both the onset temperature and peak temperature of gelatinization increased, indicating enhanced thermal stability of the starch. Scanning electron microscopy observations further revealed that FSCP formed a protective layer on the surface of starch granules, thereby alleviating freeze-induced structural damage. Rheological analysis showed that FSCP increased the storage modulus, indicating the formation of a more stable starch network. Consequently, the rapidly digestible starch content decreased by up to 22.31 ± 0.36% after 6 weeks of freezing, with 1.5% FSCP identified as the optimal addition level. This study establishes a mechanistic relationship among water immobilization, starch reassociation, and digestibility and provides a novel strategy for improving the quality and nutritional functionality of frozen starch-based foods. Future work should verify the efficacy of FSCP in frozen dough products (such as frozen steamed breads and dumplings) and test the cost-effectiveness of the antifreeze additive.

Xanthine (XOE) is an important indicator for evaluating the freshness of aquatic products. This study successfully synthesized three-dimensional cobalt sulfide nanoflowers loaded with gold nanoparticles (CoS@Au). This material innovatively constructs an enzyme nanoflower cascade sensing system and integrates peroxidase like catalytic activity with surface enhanced Raman spectroscopy (SERS) enhancement capability on the same platform. In the presence of hydrogen peroxid (H 2 O 2 ), CoS@Au It can catalyze the oxidation of 3,3′, 5,5′-tetramethylbenzidine (TMB) to generate oxTMB, while producing significant color changes, strong UV–vis absorption, and Raman signals. This study presents a dual-mode sensor that effectively integrates the intuitive simplicity of colorimetry with the high sensitivity of SERS. This design overcomes the limitations of single-mode methods, such as restricted detection sensitivity and susceptibility to interference, by enabling cross-validation between the two modes. The constructed SERS/colorimetric platform achieves a detection limit of 9.69 × 10 −11 mol/L for XOE, thereby realizing ultrasensitive detection and visual analysis of analytes in shrimp and fish food samples. These results demonstrate its strong application potential in complex practical applications.

This study synthesized mesoporous polydopamine nanoparticles (MPDA) through emulsion-induced interfacial polymerization method to encapsulate thyme essential oil (TEO). The resulting mesoporous polydopamine-thyme essential oil composite (MT) was incorporated into tannic acid-fish scale gelatin (TF) matrix. Upon near-infrared irradiation, the MT-TF composite film achieved a temperature increase of up to 70.1 °C and exhibited sustained as well as tunable release of TEO. The released TEO acted synergistically with the photothermal effect, endowing the MT-TF film with strong antibacterial activity against Staphylococcus aureus and Escherichia coli , achieving a kill rate exceeding 99 %. Additionally, the film demonstrated antifungal efficacy against Botrytis cinerea . In cherry tomato preservation experiments, the 0.3 % MT-TF film effectively maintained fruit quality upon near-infrared activation, thereby demonstrating potential for shelf-life extension. This work thus provides a new strategy for developing sustained-release essential oil-based photo-thermoactive packaging systems.

A novel and highly efficient approach to obtain magnetic molecularly imprinted polymers is described to detect avermectin in fish samples. The magnetic molecularly imprinted polymers were synthesized by surface imprinting polymerization using magnetic multiwalled carbon nanotubes as the support materials, atom transfer radical polymerization as the polymerization method, avermectin as template, acrylamide as functional monomer, and ethylene glycol dimethacrylate as crosslinker. The characteristics of the magnetic molecularly imprinted polymers were assessed by using transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, vibrating sample magnetometry, X-ray diffraction, and thermogravimetric analysis. The binding characteristics of magnetic molecularly imprinted polymers were researched through isothermal adsorption experiment, kinetics adsorption experiment, and the selectivity experiment. Coupled with ultra high performance liquid chromatography and tandem mass spectrometry, the extraction conditions of the magnetic molecularly imprinted polymers as adsorbents for avermectin were investigated in detail. The recovery of avermectin was 84.2–97.0%, and the limit of detection was 0.075 μg/kg. Relative standard deviations of intra- and inter-day precisions were in the range of 1.7–2.9% and 3.4–5.6%, respectively. The results demonstrated that the extraction method not only has high selectivity and accuracy, but also is convenient for the determination of avermectin in fish samples.

The impacts of the extent of pasteurization treatments (90 °C; 8 min, mimicked home-cooking – 25 min, mimicked commercial pasteurization) on the generation of two potential hazardous substances, N ε -carboxymethyllysine (CML) and N ε -carboxyethyllysine (CEL), in fish steaks were investigated from the initial pasteurization throughout the later storage and reheating. A more intense pasteurization treatment not only resulted in more CML/CEL generated in fish steaks during the pasteurization, but also promoted CML/CEL formation during subsequent storage (0 °C, 0–7 d). The mean formation rates of CML and CEL (zero-order reaction) in commercially pasteurized fish steaks were 145 % and 95 % faster, respectively, compared to home-cooked ones during storage. The reheated (75 °C, 10 min) fish steaks previously subjected to commercial pasteurization followed by 7 d of storage contained 335 % more CML and 120 % more CEL than the home-cooked ones, implying the necessity to reduce these potentially hazardous compounds in commercial precooked muscle foods.

Food poisoning caused by histamine ingestion is one of the prevalent allergies associated with fish consumption in the world. Reliable detection of histamine from fish by a portable platform was of urgent importance to food safety. A portable technology for on-site monitoring of histamine in tuna was established through combined azo-derivatized thin-layer chromatography (TLC) with surface-enhanced Raman scattering (SERS) spectroscopy. The real tuna meat sample was directly applied onto the portable sensor for the separation of histamine and azo-derivatizing of histamine was reacted on the TLC plate. The colorless histamine was visualized by azo-derivatization after spraying Pauly reagent onto the diatomite TLC plate. The molecule information and concentration of the histamine was measured and calculated by SERS spectra. Diatomite TLC plate was capable of separating histamine with 1.32 × 10 −7 M of Au colloid for the SERS enhancement. Accordingly, the limit of detection of histamine from mixture sample could achieve 2.8 × 10 −4 ppm. These results indicated that the portable azo-derivatized TLC-SERS sensor not only visualizes the histamine but also improves the intensity of the Raman spectra. The azo-derivatized TLC-SERS sensor could be applied for rapid, convenient, and ultrasensitive point-of-care sensing of histamine in fish.

Biogenic amines (BAs) in fish or fish products may render the food toxic, which allow to be used as an indication for microbial spoilage. Thus, it is crucial to construct a rapid and sensitive analytical method for detection of BAs. In this work, based on rhodamine 6G-loaded and MnO 2 nanosheets-coated mesoporous silica nanospheres (MSNs), a highly sensitive fluorescence probe was designed and developed. Wherein, a “signal on” fluorescence was achieved by using R6G (λ emi : 553 nm) as an energy donor and MnO 2 nanosheets as the energy acceptor. As BAs exist, diamine oxidase will catalyze BAs to generate hydrogen peroxide (H 2 O 2 ), which can reduce MnO 2 to Mn 2+ , resulting with the dissociation of MnO 2 nanosheets and the signal recovery of R6G. Under optimal conditions, the analytical method obtained a wide linear detection range of 10 ∼ 400 nM with a detection limit of 5.97 nM (S/N = 3, n = 3). As a proof-of-application study, the analytical method was verified by spiked fish samples with recoveries of 93.97 to 101.57 % and was accurate at 95 % confidence level, indicating its good performance in detection of BAs and promising applications in food safety.

This study was aimed to investigate the structural and immunological properties of parvalbumin from mandarin fish during the Maillard reaction. The microwave-assisted the Maillard reaction was optimized by orthogonal designed experiments. The results showed that the type of sugar and heating time had a significant effect on the Maillard reaction (p< 0.05). The SDS-PAGE analysis displayed that the molecular weight of parvalbumin in mandarin fish changed after being glycated with the Maillard reaction. The glycated parvalbumin was analyzed by Nano-LC-MS/MS and eleven glycation sites as well as five glycation groups were identified. By using the indirect competitive ELISA method, it was found that microwave heating gave a higher desensitization ability of mandarin fish parvalbumin than induction cooker did. In vitro gastric digestion experiments showed that microwave-heated parvalbumin was proved to be digested more easily than that cooked by induction cookers. The microwave-assisted Maillard reaction modified the structure of parvalbumin and reduced the immunoreactivity of parvalbumin of mandarin fish.Keywords:parvalbumin;Maillard reaction;glycation site;structural and immunological properties;in vitro

In this study, pentachlorobenzene was used as dummy template to synthesize a type of magnetic molecularly imprinted microsphere for pentachlorophenol. At the same time, pentachloroaniline was coupled to streptavidinated horseradish peroxidase to synthesize an enzyme labeled tracer. The two reagents were used to develop a semi-homogeneous method on conventional microplate for detection of pentachlorophenol in fish samples. Due to the use of biotinylated horseradish peroxidase as signal amplification agent, the method sensitivity was improved for 375 folds in comparison with the use of conventional horseradish peroxidase labeled tracer with a limit of detection of 0.8 fg/g. After comparison, it was found that this method showed better performances than the previous immunoassays and molecularly imprinted polymer based methods for detection of pentachlorophenol. This study for the first time reported a magnetic molecularly imprinted microsphere based semi-homogeneous method for detection of small molecule, and this method could be used for routine determination of pentachlorophenol residue in fish samples.

Olaquindox residues in food from its illegal use has received great attention. Here, an immunoassay strategy integrating an upconversion nanoparticle (UCNP)-based immunochromatographic strip with a fluorescence reader was proposed for the highly selective and sensitive detection of olaquindox. Polyacrylic acid-functionalized UCNPs were synthesized using a simple ligand exchange process and combined with an olaquindox polyclonal antibody to form a fluorescent probe. This approach achieved a sensitive response and specific recognition of olaquindox. A convenient upconversion fluorescence reader was introduced to implement accurate and sensitive quantitative analysis of olaquindox based on the fluorescence intensity of control and test lines on a strip. Under optimal conditions, the method demonstrated a favorable linear range (0–50 ng/mL) and sensitive detection (1.42 ng/mL, S/N = 3). This method was applied successfully to determine olaquindox in fish muscle and water samples, and results were consistent with an HPLC approach, and considered a promising strategy for monitoring olaquindox residuals.

In this study, a colorimetric hydrogel with a strong network employing natural anthocyanin as an indicator was developed for visual monitoring of shrimp and fish spoilage. Polyvinyl alcohol (PVA) and sodium alginate (SA) were used as matrix models to prepare functional hydrogels with a double network structure by a simple freezing/thawing process and calcium cross-linking in SA. To enhance the strength of the hydrogel, aramid nanofibers (ANFs) were introduced which were obtained from aramid fibers by a deprotonation method. The natural anthocyanin extract was extracted from purple cabbage by a hot water soaking method and acted as the color sensing substance in the hydrogel. Smartphone-based RGB color analysis showed good color response of the hydrogel indicators to amines. Various characterization methods revealed that the hydrogel also had good thermal stability, mechanical properties, and water resistance. The hydrogels exhibited good performance for the spoilage monitoring of shrimp and fish through correlation analysis, indicating that they are promising candidates for sensing applications.

A novel fluorescent membrane based on carbon dot embedded photonic crystal molecularly imprinted polymer (PCMIP@CDs) was developed for fluorometric and colorimetric dual-mode determination of sulfadimethoxine with excellent selectivity, quick response, and reusability. In the presence of sulfadimethoxine, fluorescence quenching and red shift of diffraction peak from PCMIP@CDs were observed because of the photo-induced electron transfer and structural change of PCMIP@CDs, accompanied by a visual color change from blue to green. The fluorescence quenching efficiency and the red-shift of the diffraction peaks were positively correlated with the logarithms of the sulfadimethoxine concentration at 10 −12 –10 −5 and 10 −10 –10 −5 mol L −1 , respectively. The sensor achieved a limit of detection of 0.08 pmol L −1 (fluorescence method) and 2.75 pmol L −1 (colorimetric method, 3 σ , n = 9). The developed PCMIP@CD membrane was applied for the detection of sulfadimethoxine in fish samples with favorable recovery of 84.8–102.9%.
