Effect of temperature on bighead carp (<i>Hypophthalmichthys nobilis</i>) skin collagen: Structure, emulsification and rheological properties.

ABSTRACT: Temperature significantly affects the function and application of collagen. In this study, bighead carp skin collagen (SC) with a triple helix structure was prepared. Circular dichroism experiments revealed that at a thermal denaturation temperature (Td = 31.1 °C), the positive peak of SC disappeared, with a triple helix fraction of 24.11 %. Secondary structure results showed that the random coils (36.43 ± 2.93 %) became the dominant conformation at Td. Emulsifying property results showed that as the temperature increased, the emulsifying activity index improved. At 30 °C, the EAI value of the SC solution peaked at 161.83 ± 2.87 m²/g. Steady shear test results showed that the pseudoplasticity of SC solutions weakened as temperature increased. Dynamic frequency sweep results reve
