Matrine-incorporated chitosan active biofilms with enhanced barrier and antimicrobial properties for postharvest fruit preservation

This dataset contains the original experimental data supporting the findings of the study titled "Matrine-incorporated chitosan active biofilms with enhanced barrier and antimicrobial properties for postharvest fruit preservation." The dataset includes 10 sheets with the following experimental measurements: 1. Mechanical properties: Tensile strength (TS), elongation at break (E%), and Young's modulus of chitosan films with varying concentrations of acetic acid, alkali, and citric acid. 2. DPPH antioxidant assay: DPPH free radical scavenging activity . 3. ABTS antioxidant assay: ABTS free radical scavenging activity . 4. Moisture content: Moisture content of film samples after drying. 5. Water solubility: Water solubility of film samples. 6. Water vapor permeability: Water vapor permeability of film samples. 7. Cytotoxicity assay: Cell viability of films against CPT (20 μg/ml) at concentrations of 0, 0.5, 1, 2, and 4 mg/ml. 8. Thickness: Thickness measurements of film samples (20% and 30% acetic acid control and sample groups). 9. E. coli growth curve: Optical density (OD) measurements of E. coli cultured with film samples at different time points (0-10 h). 10. S. aureus growth curve: Optical density (OD) measurements of S. aureus cultured with film samples at different time points (0-10 h). All experiments were conducted at Huaiyin Institute of Technology. Data are organized in Microsoft Excel format with detailed annotations. Raw data and calculated mean values are both included. For questions regarding this dataset, please contact: [e-mail]
