Dyeing of wool fabrics with natural dyes from Phytolacca berries has been studied. The effect of dye concentration, dye bath pH, dyeing time and temperature were discussed. The influence of chitosan application on the dyeing properties of wool fabrics was investigated. The SEM photographs of chitosan treated wool fabrics clearly depict the deposition of chitosan on the fibers. The effect of chitosan concentration, dye bath pH, dyeing time and temperature has been studied by orthogonal experiment. It has been proved that the dyed wool samples pretreated by chitosan have higher color fastness, faster dyeing rate, and better antibacterial properties compared with untreated ones.

Veterinary drug residues in meat seriously harm human health. Rapid and accurate detection of veterinary drug residues is necessary to minimize contamination. Taking ofloxacin (OFX) residues in mutton as an example, the near-infrared hyperspectral imaging combined with explainable AI was used to evaluate the importance of feature wavelengths in the convolutional neural network-stacked sparse auto-encoder (CNN-SSAE) model for chemical properties. Based on this, the qualitative (residue identification-residue level identification) and quantitative detection of OFX residues in mutton was realized. The results showed that the accuracy of CNN-SSAE in identifying residue and residue level of OFX was 100% and 93.65%, respectively, and the correlation coefficients for validation (R 2 P ) in quantitative detection of OFX residue was 0.8980. In addition, SHapley Additive exPlanation (SHAP) values were used to identify feature wavelengths that contribute the most in the CNN-SSAE model, which effectively explained the quality attribute information that spectral and chemical values may improve the predicted results in the model decision process. The reliability of the CNN-SSAE model was evaluated by statistical validation methods (F-test and T-test). Finally, the visualization diagram of OFX content distribution was established. This study provides a method reference for explainability detection of veterinary drug residues.

Non-destructive detection of veterinary drug residues in meat products is critical for ensuring food safety and human health. The feasibility of using visible near-infrared (Vis-NIR) and near-infrared (NIR) hyperspectral imaging (HSI) system combined with data fusion for the prediction of pefloxacin residues in mutton was investigated in this study. A partial least squares regression optimization model was developed by multivariate data processing methods. The results showed that the low-level fusion (LLF) produced better results with R 2 P = 0.907 and RMSEP = 0.462 as compared to individual data blocks. Furthermore, intermediate-level fusion (ILF) based on iterative retention of informative variables algorithm showed the best results with R 2 P = 0.940 and RMSEP = 0.375. Finally, the visualized distributions of Vis-NIR and NIR based on the optimal model combination were mapped. The results have demonstrated that a combination of HSI with data fusion may be applied to rapidly and non-destructively detect pefloxacin residues in mutton.

The demand for gold recovery from e-waste is steadily increasing, and thus the design and preparation of efficient adsorbents for gold recovery is of great environmental and economic importance. This study explored wool keratin (WK) waste, an S-containing natural protein resource, as well as cellulose to fabricate functional adsorbents for selective gold recovery, based on the strong affinity of S element to gold. WK and cellulose were firstly dissolved simultaneously in ether-functionalized protic ILs by a hydrogen-bonding-acceptor strengthening strategy, and rheological research revealed that the ratio of WK/cellulose, concentration and test temperature had important influences on the rheological properties of WK/cellulose/[DBNH][Mea] solutions. WK/cellulose composite aerogels were prepared by a simple sol–gel transition process and followed by freeze-drying technique, and were systematically characterized by solid state nuclear magnetic resonance (SSNMR), FTIR, XRD, TGA, SEM and elemental analysis. The optimal W60C40 aerogel had excellent adsorption capacity (330.8 mg/g), adsorption selectivity for Au(III), and good recoverability with a high recovery rate (94 %) of gold after five times of reuse, providing a new and efficient type of bio-based adsorbent for gold recovery via an environmentally friendly and economically feasible approach.

Goat lactoferrin is an N-glycoprotein, and its glycan moieties are essential for its biological activity. However, the structures of these glycans, particularly the sialylated isomers with α-2,3- or α-2,6-linkages, remain poorly characterized. Utilizing online hydrophilic liquid chromatography-tandem mass spectrometry, our study characterized N-glycans in goat lactoferrin across different lactation stages, and the putative structures of the 86 N-glycans of goat lactoferrin were presented, including 53 previously undetected ones. The content and variety of N-glycans decreased from colostrum to mature milk, with transitional milk exhibiting the highest levels of neutral and high-mannose N-glycans. Colostrum was particularly rich in fucose- and sialylated N-glycans, especially those with α-2,6-linkages. Notably, the α-2,6-linked sialylated N-glycan H5N4F1A1-1 was 7.09-fold and 12.85-fold more abundant in colostrum compared to transitional and mature milk, respectively. These findings provide valuable insights into the structure of lactoferrin and could facilitate the development of functional goat milk products.

Bone defects, induced by trauma, infection, tumor resection, osteoporosis, and congenital deformities, severely affect patient health both physiologically and psychologically, imposing substantial burdens on healthcare systems and public resources. Bone defect repair involves a complex biological process that orchestrates events such as immune modulation and osteogenic differentiation. Consequently, ideal materials for bone defect regeneration should possess capabilities in both immune regulation and osteogenesis. In this study, we synthesized a kind of covalent organic framework (COF) nanoparticles at room temperature and modified their surface with polydopamine (PDA), resulting in PDA-functionalized COFs (PCOFs). Utilizing the adhesive properties of PDA, we successfully loaded icariin (ICA) onto the PCOFs nanoparticles, forming ICA@PCOFs. Comprehensive characterization techniques, including visual inspection, scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA), confirmed the successful synthesis of ICA@PCOFs nanoparticles. Subsequent optimal concentration determination via the CCK-8 assay, and further experiments including alkaline phosphatase (ALP) activity, alizarin red S (ARS) staining, and immunofluorescent staining for osteocalcin (OCN), runt-related transcription factor 2 (Runx2), inducible nitric oxide synthase (iNOS), and mannose receptor (CD206), assessed their capability to modulate macrophage polarization and promote osteogenesis. The results revealed that ICA-loaded nanoparticles demonstrated significant potential in vitro for immune regulation and promoting stem cell osteogenic differentiation. These findings suggest that ICA@PCOFs nanoparticles could represent a promising therapeutic platform for bone defect regeneration, offering dual functionalities in immune modulation and osteogenesis promotion.

Phosphorylated wool with enhanced ability to absorb cationic dyes is helpful to dye wool fabrics using cationic dyes with good dyeing properties, which is more economic and ecofriendly compared to the traditional dyeing process of acid dyes with poor wet fastness. Phosphorylation can be performed by applying chemical reagents which tend to cause a problem of environmental pollution and the fibers can be damaged seriously under harsh reaction conditions, or using enzymes which are currently somewhat discouraged due to significant cost of the enzymes and their decreased stability at the reaction conditions. In this study, non-toxic glucose 6-phosphate was applied to phosphorylated modification of wool via Maillard reaction under a mild condition to enhance the dyeing properties of wool fabric for cationic dyes. The reaction between glucose 6-phosphate and wool keratin was demonstrated from the results of sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), particle diameter, Fourier transform infrared spectra (FTIR) and Energy Dispersive X-ray test (EDS). It was found that phosphorylation modification scarcely changed the mechanical properties of the wool fabric. Maillard browning on the wool could be avoided by accurately controlling the reaction time. Dyeing properties of phosphorylated wool fabric with cationic dyes were markedly enhanced. The exhaustion of phosphorylated wool fabric for two cationic dyes: Cationic Brilliant Red 5 GN and Brilliant Yellow B 6 GL increased from 38.6% to 18.9%–84.5% and 67% respectively by comparing with that of the wool fabric without modification and better color strength (K/S) and very good wash fastness properties obtained. The results indicated that phosphorylated modification of wool with glucose 6-phosphate could be a potential, safe and cleaner approach to develop a more efficient and economic dyeing process for wool fibers with cationic dyes.

The knowledge of the changes in the lipid species in irradiated goat meat is expected to clarify the beneficial effects of irradiation on meat preservation. This study explored the characteristic lipid composition and the changes in irradiated goat meat based on quantitative lipidomics strategy by LC–MS. Totally, 12 subclasses of 174 lipids were identified with significant differences ( p < 0.05, VIP > 1), and the absolute quantitative analysis of characteristic lipids was achieved. Significant lipid variables were involved in the major pathways of glycerophospholipid and sphingolipid metabolism. Moreover, significant increases during irradiation were found in total TG, PC, PE, LPE, Cer, LPC and SPH, while the total DG, PS, PG, PI and SM decreased after irradiation. Noteworthily, DHA-enriched PC (18:4/22:6) + H, a core nutrient for human health, exhibited an increase in the irradiated group. These results provide a basis for lipid quantitative alterations in irradiated goat meat and application of irradiation in meat preservation.

This work aims to explore the contribution of prickly ash (Zanthoxylum bungeanumMaxim) on the taste perception of stewed sheep tail fat. Liquid chromatography-tandem quadrupole time of flight mass spectrometry (LC-QTOF-MS) was applied to analyze the taste-related compounds. A total of 99 compounds in different sheep tail fat samples were identified. The semi-quantitative results showed that there were differences between the samples. The partial least squares discriminant analysis (PLS-DA) model without overfitting was used to investigate the effect of prickly ash. Eleven marker compounds were predicted with a variable importance for projection > 1, fold change > 2 andp< 0.05. An additional experiment showed that guanosine 5′-monophosphate, malic acid, inosine and adenosine 5′-monophosphate could improve the umami and saltiness taste of stewed sheep tail fat.Keywords:sheep tail fat;taste compounds;LC-QTOF-MS;PLS-DA;sensory analysis;additional experiment

ABSTRACT This study was carried out to investigate the effects of pH and heat on the structure and function of milk proteins by comparing goat milk treated under different pH and temperature conditions. The results showed that pH had a significant effect on the thermal stability of goat milk proteins, and the proteins were least thermally stable at pH 7.7. Except for the pH 6.9 goat milk, the surface hydrophobicities of the milk proteins at various pH values reached their maxima at 85°C. The particle size, zeta potential, and content of regular secondary structure also decreased significantly at 85°C, and the turbidity of milk proteins under alkaline pH conditions was lower than that under acidic conditions. It was concluded that alkaline conditions resulted in better emulsion stability and oil-holding capacity, and acidic conditions offered better foaming ability, foam stability, and water-holding capacity for goat milk protein during heat processing. It can also be seen that 85°C was the key temperature for milk proteins after changing the pH of the milk. This paper provides a theoretical basis for optimizing the processing conditions for goat milk and the applications of goat milk proteins.

Endogenous benzoic acid causes detrimental effects on public health, but the underlying mechanisms often remain elusive. Benzoic acid (0.00–40.00 mg L − 1 ) was detected from sixty fermented goat milk samples in six replicates, indicating the existence of endogenous benzoic acid. Herein, we investigated the effects of benzoic acid on the variations of metabolome and proteome signatures in fermented goat milk via integrative metabolomics (LOQ 2.39–98.98 μg L − 1 ) and proteomics approach based on UHPLC-Q-Orbitrap HRMS. Explicitly, benzoic acid reduced the content of taurine (7.06–4.80 mg L − 1 ) and hypotaurine (3.86–1.74 mg L − 1 ) due to a significant decrease in the levels of glutamate decarboxylase 1 by benzoic acid. The reduction in lactose (7.13–5.31 mg L − 1 ) and d -galactose (4.39–3.37 mg L − 1 ) content was related to the decrease in α-lactalbumin and β-galactosidase levels, respectively, in fermented goat milk containing 40.00 mg L − 1 benzoic acid. Meanwhile, the levels of maltose (22.84–16.53 mg L − 1 ) and raffinose (4.19–3.10 mg L − 1 ) progressively decreased with increasing benzoic acid concentrations (0.00–40.00 mg L − 1 ), which had detrimental effects on the nutritional quality of fermented goat milk. Additionally, the concentration of benzoic acid and fermentation temperature are the most important factors to control the loss of nutrients in fermented dairy products.

The skull defects are challenging to self-heal, and autologous bone graft repair has numerous drawbacks. The scaffolds for the rapid and effective repair of skull defects have become an important research topic. In this study, polyvinyl alcohol (PVA)/β-tricalcium phosphate(β-TCP) composite scaffolds containing icariin (ICA) were prepared through direct-ink three-dimensional (3D) printing technology. β-TCP in the composite scaffold had osteoconductive capability, and the ICA molecule had osteoinductive capacity. The β-TCP and ICA components in the composite scaffold can enhance the capability to repair skull defects. We show that ICA exhibited a slow-release behaviour within 80 days. This behaviour helped the scaffold to continuously stimulate the formation of new bone. The results of in vitro cell compatibility experiments showed that the addition of ICA molecules contributed to the adhesion and proliferation of MC-3T3-E1 cells. The level of alkaline phosphatase secretion demonstrated that the slow release of ICA can promote the osteogenic differentiation of MC-3T3-E1 cells. The introduction of ICA molecules accelerated the in situ bone regeneration in in vivo. It is concluded that the 3D-printed PVA scaffold with β-TCP and ICA has a wide range of potential applications in the field of skull defect treatment.Keywords:three-dimensional printing;polyvinyl alcohol;icariin;β-tricalcium phosphate;skull base defects
