Background Biochar has attracted considerable attention as a low-cost adsorbent comprised of carbon matrix and mineral for treatment of wastewater. The main purpose of this work was to manufacture CaCO 3 -rich biochars using crayfish shell as feedstock for removal of Cu(II) and Pb(II) from aqueous solution. Methods Pristine and magnetic biochars were prepared via direct pyrolysis and K 2 FeO 4 -promoted pyrolysis , respectively, and characterized by element analysis, BET, FTIR, SEM-EDS, XRD and XPS. Moreover, their adsorption capabilities toward Cu(II) and Pb(II) were investigated in aqueous solution. Findings A large amount of CaCO 3 was assembled on the pristine biochar pyrolyzed at 600 °C, leading to 715.10 mg/g and 1682.87 mg/g adsorption capacities for Cu(II) and Pb(II), respectively. Whereas, CaCO 3 and single phase Fe 3 O 4 were simultaneously introduced into the magnetic biochar with K 2 FeO 4 -promoted pyrolysis at 600 °C using 1/1 (g/g) ratio of K 2 FeO 4 to crayfish shell, where 417.05 mg/g and 974.10 mg/g maximum adsorption capabilities were obtained for Cu(II) and Pb(II) with 29.66 emu/g saturation magnetism, respectively. Cu(II) and Pb(II) were mainly adsorbed onto the biochars as carbonates and oxides by their interaction with CaCO 3 and carbon matrix.

Summary The effect of complex organic acids (COA) treatment at different concentrations (0%, 1%, 5%, 10% and 15%) on the myofibrillar protein (MP) structure and meat quality of crayfish ( Procambarus clarkii ) was investigated. The results showed that with increasing concentrations of COA treatment, the sulfhydryl content of MP decreased and dityrosine content increased. The MP secondary structure has a reduced α-helix content and an increased β-fold content. The MP tertiary structure unfolded, exposing hydrophobic and other amino acids to a polar environment. MP aggregation was induced in the 1% and 5% COA treatment groups and MP degradation was induced in the 10% and 15% COA treatment groups. Crayfish meat in the 5% COA treatment group showed improved textural properties due to protein aggregation. It also enhanced the colour, aroma and micromorphology of the crayfish meat.

Biogenic amines are a group of nitrogen substances and widely adopted to assess the food safety, especially for the aquatic products. In China, crayfish (Prokaryophyllus clarkii) have become one of the most famous aquatic products and form a complete industrial value chain. To ensure the safety of the crayfish industrial chain, a rapid and nondestructive method for determining the biogenic amines of crayfish by near infrared spectroscopy coupled with chemometrics was proposed in this study. The quantitative models of histamine, tyramine, cadaverine, and putrescine were built by using the partial least squares (PLS) regression. The spectral preprocessing and the wavelength selection methods were adopted to optimize the models. For histamine, cadaverine, and putrescine in peeled or whole tails, reasonable quantitative results can be obtained by using the optimized models; the coefficient of determination (r2) are 0.88 and 0.90, 0.88 and 0.91, 0.89, and 0.84, respectively. As for tyramine in peeled or whole tails, the results are acceptable and the coefficient of determination (r2) is 0.83 and 0.74, respectively.

Balancing flavor and health in Marinated Crayfish (MC) requires precise salt addition. This study deciphered how salt (0–4 %) shapes flavor via integrated metabolic and volatile profiling. Multivariate statistics identified 15 key non-volatile and 11 pivotal volatile metabolites. Mechanistically, salt modulates flavor through salting-out and osmotic effects, alongside lipid oxidation changes. At lower levels (0–1 %), salt retained endogenous free amino acids and nucleotides, though the product tasted bland due to insufficient saltiness. Conversely, higher salt (3–4 %) enhanced saltiness but reduced endogenous compounds and impeded key exogenous volatiles, including β-pinene, limonene, sabinene, 4-carene, copanene and p-cymene. Critically, increased salt shifted lipid oxidation pathways, elevating 2-decanone, p-menth-1-en-9-al, and limonene oxide, while suppressing decanal and 1-octen-3-ol. Collectively, NaCl imparts saltiness but depletes characteristic flavor compounds. Therefore, 2 % salt is identified as the optimal target for MC, balancing saltiness with flavor complexity and providing a practical guideline for future optimization.

Maduramicin (MAD) is widely introduced into aquatic environments and results in the contamination of fish products. Worryingly, the consumption of MAD-contaminated crayfish (Procambarus clarkii) may induce symptoms of Haff disease. In this study, to monitor this potential contamination and to understand the residue and elimination characteristics of MAD in edible tissues of crayfish, a sensitive and efficient ultra-performance liquid chromatography–tandem mass spectrometry method was developed, validated, and applied. After extraction with acetonitrile and purification by solid-phase extraction column, multiple-reaction monitoring mass spectrometry with positive ionization mode was used to determine MAD’s residues. The limits of detection and of quantification were 6 μg·kg−1and 20 μg·kg−1, respectively. The fortified recoveries ranged from 74.2% to 110.4%, with relative standard deviation of 1.2% to 10.1%. Furthermore, MAD was completely eliminated after 3 and 5 days from abdominal muscle and hepatopancreas tissues of crayfish, respectively. The maximum residue limits (MRLs) of MAD respectively was 200 μg·kg−1in muscle and 600 μg·kg−1in the hepatopancreas, and its withdrawal time in both edible tissues was 25.8 °C·d. Collectively, the results of this study indicate the proposed method is an efficient tool to evaluate the public health risk associated with crayfish consumption.Keywords:maduramicin;ionophore antibiotic;UPLC-MS/MS;veterinary drug residue;crayfish;Haff disease

Although aquatic products are nutritious, they are highly perishable and tend to develop undesirable odors. Traditional methods of preservation and deodorization often suffer from limitations including inadequate efficacy and safety issues. Here, we propose a triple-synergistic strategy that integrates host-guest complexation by β-cyclodextrin, physical adsorption enabled by a highly porous nanofiber film, and the bioactivity of grape seed extract. The multifunctional nanofiber film, composed of polyvinyl alcohol, β-cyclodextrin, and grape seed extract, was prepared via electrospinning. At a 10 % grape seed extract loading level, the triple-synergistic strategy endowed the film with the remarkable adsorption rate (74.08 %), along with excellent antibacterial and antioxidant performance. This multi-mechanism action effectively extended the shelf life of crayfish meat ( Procambarus clarkii ) and minimized the production of undesirable odors during storage. Ultimately, the underlying mechanism of these excellent performances was expected to inspire the design of other aquatic products packaging films.

Chitin is a natural biomass material with wide sources and high application potential, but the solvents for dissolving chitin are very limited. In this work, ternary alkaline deep eutectic solvents (DESs) containing amino acids, urea, and 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) were prepared, which can successfully achieve the dissolution of chitin and can be recycled. By adjusting the type of amino acids and the amount of DBU, the maximum solubility of chitin can reach 6.0 wt %. In addition, unlike the reported acidic DES system, this new ternary alkaline DES not only efficiently extracted chitin from crayfish shell waste but also efficiently prepared calcium lactate (CL), which successfully realized the effective recycling of calcium resources. Through 11 sets of extraction conditions, proteins in the crayfish shell were effectively removed, and the yields of chitin and CL remained above 85 and 90%, respectively. Finally, chitin nanofibers were successfully prepared by ultrasonic treatment with extracted regenerated chitin. Further processing of the chitin nanofibers can yield chitin films with high transparency and high tensile strength (63.2 MPa). It provides a novel DES system to dissolve chitin and an environmentally friendly utilization strategy to efficiently extract chitin and prepare CL from crayfish shell waste, thereby producing high-performance functional materials.

A method for monitoring the freshness of crayfish by near-infrared spectroscopy combined with chemometrics was proposed in this study. The total volatile basic nitrogen (TVBN), K value and biogenic amine were adopted as the indexes of freshness. The 120 peeled and the 120 whole tail samples were utilized to build the quantitative models by partial least squares (PLS) regression, respectively. The spectral pretreatment and the variable selection methods were adopted to further improve the models. For the models of TVBN and K value, the combination of continuous wavelet transform (CWT) and randomization test (RT) method could improve the predictability effectively. The combination of 1st derivative and RT method could get better results for the optimization of the biogenic amine models. The optimized models were evaluated by 40 peeled and the 40 whole tail samples, and then utilized to predict the three indexes in another 32 peeled tails and 40 whole tail samples for practical application. Reasonable results were obtained for the samples with TVBN levels ranging from 28.01 mg/kg to 284.89 mg/kg, K value levels ranging from 13.04 to 87.36% and biogenic amines ranging from 148.57 mg/kg to 663.71 mg/kg. For the TVBN, K value and biogenic amine in the 32 peeled tail samples, the correlation coefficients between the results calculated by the optimized models and those measured by the standard methods were 0.95, 0.94 and 0.96 respectively. As to the three freshness indexes in 40 whole tail samples, the correlation coefficients were 0.95, 0.93 and 0.94, respectively.

Bacterial spores in food exhibit strong resistance to conventional processing methods, posing a significant challenge to food safety. This scientific aim of the study was to compare the antimicrobial effects of organic acids and plasma-activated lactic acid (PALA) on the specific spoilage bacteria (SSB) spores in cooked crayfish ( Procambarus clarkii ), and further explored the antimicrobial mechanism of PALA against Bacillus cereus spores. Plasma activation enhanced the antimicrobial efficacy of lactic acid (LA), as 1 % PALA showed equivalent antimicrobial efficacy to 1.5 % LA against spores. Microstructural changes and leakage of core contents indicated that PALA treatment caused damage to the inner membrane (IM) of B. cereus spores. Then, the spore germination experiments further revealed that PALA treatment disrupted the function of SpoVA proteins in the IM, leading to a significant decrease in spore germination capacity. Furthermore, inactivated spores did not regain viability after treatment with lysozyme or Ca-DPA, and no mutants were detected among the surviving spores. These results demonstrated that the inactivation effect of PALA on B. cereus spores is closely related to the structural disruption and dysfunction of the spore IM. Additionally, PALA treatment extended the shelf life and maintained the product quality of cooked crayfish, supporting PALA as a promising measure for controlling microbial safety.

Crawfish shell wastes (CSW) are abundant with valuable substrates, which possess great resource potentials. This work has revealed the feasibility of CSW reutilization for effective volatile fatty acids (VFAs) generation with waste active sludge (WAS) via anaerobic fermentation. The maximum VFAs generation reached 17963 mg COD/L when the CSW/WAS mass ratio was 3.25:1, while it was 784 mg COD/L in the control reactor. Meanwhile, each gram of CSW could be transformed into 264 mg COD equivalent VFAs. The feed of CSW brought in massive organic substrates, which significantly promoted the solubilization , hydrolysis and acidification processes in the CSW/WAS co-fermentation systems simultaneously. The metabolism of carbohydrates took priority over proteins in contributing to the VFAs promotion. More importantly, the functional anaerobes ( i.e. , Paludicola sp. and Macellibacteroides sp.), which participated in the main substrates decomposition with the VFAs as the primary metabolites , were evidently enriched in the presence of CSW. The critical hydrolases and acid-forming enzymes relevant to VFAs biosynthesis were all enhanced. Moreover, the key genes encoding for the main substrates metabolisms ( i.e., chitin) and VFAs production were remarkably up-regulated. The evident promotion of microbial activities and metabolic functions was mainly ascribed to the favorable fermentation conditions ( i.e., pH, ORP and C/N) induced by CSW conditioning. This study proposed an innovative strategy to recover high-value products from CSW, and in-depth insights of microbial traits and genetic functions in CSW/WAS co-fermentation systems.
