Extraction and characterization of collagen from the eel Bone

摘要

Eel bones as raw material, the use of enzyme and acid extraction of pepsin-soluble collagen (PSC), and its physical and chemical properties were determined. The results showed that the thermal denaturation temperature of the pepsin-soluble collagen (PSC) is 25 °C; shrinkage temperature is 57.94 °C, UV absorption value of 234nm. Infrared absorption spectra show that the pepsin-soluble collagen retained the triple helix structure.
