“…As shown in Table 4, the tensile strength of pure CS membrane and CS/β-CDP composite membrane is 4.95 ± 0.22 MPa and 6.37 ± 0.31 MPa, the elongation at break is 2.68 ± 0.17% and 3.79 ± 0.56%, and Young's modulus is 5.12 ± 0.67 MPa and 7.56 ± 0.78 MPa, respectively. These three characteristics of the CS/β-CDP composite membranes are better than those of pure CS membranes, which suggests that glutaraldehyde has a strengthening impact on the CS/β-CDP and CS polymer matrix, in line with a recent report by Nie and colleagues [36]. This is mostly due to the electrostatic interaction of glutaraldehyde between CS and β-CDP, which enhances polymer chains' flexibility, swelling, and susceptibility to fracture, which reduces mechanical resistance [45,46].…”

“…Regarding the membrane after BSA adsorption, the absorption band observed at around 1022 cm −1 corresponds to the C-O stretching vibration of carbinol in the CS molecule [35]. The adsorption band around 1405 cm −1 is the C−N stretching vibration of methylene [36], and the weakening of peak intensity indicates that the structure of CS has changed. The 1560~1640 cm −1 is the mixed adsorption band, which is a characteristic peak of protein and mainly consists of amide I, amide II, and -NH2.…”

A significant portion of the protein in food waste will contaminate the water. The chitosan/modified β-cyclodextrin (CS/β-CDP) composite membranes were prepared for the adsorption of bovine serum albumin (BSA) in this work to solve the problem of poor adsorption protein performance and easy disintegration by a pure chitosan membrane. A thorough investigation was conducted into the effects of the preparation conditions (the mass ratio of CS and β-CDP, preparation temperature, and glutaraldehyde addition) and adsorption conditions (temperature and pH) on the created CS/β-CDP composite membrane. The physical and chemical properties of pure CS membrane and CS/β-CDP composite membrane were investigated. The results showed that CS/β-CDP composite membrane has better tensile strength, elongation at break, Young’s modulus, contact angle properties, and lower swelling degree. The physicochemical and morphological attributes of composite membranes before and after the adsorption of BSA were characterized by SEM, FT-IR, and XRD. The results showed that the CS/β-CDP composite membrane adsorbed BSA by both physical and chemical mechanisms, and the adsorption isotherm, kinetics, and thermodynamic experiments further confirmed its adsorption mechanism. As a result, the CS/β-CDP composite membrane of absorbing BSA was successfully fabricated, demonstrating the potential application prospect in environmental protection.

In this study, layer-by-layer assembly was performed to prepare sodium alginate (SA) layer and walnut-peptide–chitosan (CS) bilayer composite films. Genipin was adopted to crosslink CS and walnut peptide. The properties of walnut peptide-CS-SA composite film were determined, and the influence of material ratio on the performance of composite film was explored. According to the results, the mechanical tensile property, oil absorption property, and water vapor barrier property of the composite film were improved with the presence of genipin. Moreover, the proportion of CS and walnut peptide had significant effects on color, transmittance, mechanical properties, barrier properties, and antioxidant properties of the composite films. Among them, the composite film containing 1% (w/v) CS, 1% (w/v) walnut peptide, and 0.01% (w/v) genipin showed the best performance, with a tensile strength of 3.65 MPa, elongation at break of 30.82%, water vapor permeability of 0.60 g·mm·m−2·h−1·kPa−1, oil absorption of 0.85%, and the three-phase electrochemistry of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging rate of 25.59%. Under this condition, the tensile property, barrier property, and oxidation resistance of the composite film are good, which can provide a good preservation effect for food, and has great application potential.
