Abstract: The rheological property and thermal stability of 5 mg/mL snakehead skin collagen (SSC) were studied and compared with bovine hide collagen (BHC) at the same concentration. The effects of temperature on the dynamic viscoelasticity and fibril formation of SSC were investigated. The effects of glutaraldehyde and adipic acid N-hydroxysuccinimide (NHS) ester on the crosslinking of SSC solution were studied. The results showed that there were significant differences in rheological parameters and thermal stability between SSC and BHC at the same concentration. The molecular entanglement degree was lower and the structural stability was poorer for SSC. The dynamic viscoelasticity and fibril forming behavior of SSC were obviously temperature dependent. The NHS ester had a good crosslinking effect on SSC solution, and was expected to replace glutaraldehyde to improve the structure and properties of fish collagen based materials.

Key words: fish collagen, rheological property, thermal stability, chemical crosslinking
