Viscoelasticity of thermoreversible gelatin gels from mammalian and piscine collagens

Abstract

The concentration dependence of melt behavior and of viscoelastic parameters for both traditional mammalian samples and a range of fish gelatins were studied. The long time behavior of gelatin gels and its possible implications for gel healing were also examined. Gelatin from cold water fish displayed much lower melting behavior than typical mammalian samples. It was observed that the melting behavior fits the Takahashi model for both mammalian and fish samples.
