The extraction of collagen from eel bone using acetic acid and pepsin
The technology of extracted collagen from eel bone was studied in this paper.Acetic acid and pepsin were adopted on the extraction technology including immersion time,quantity of enzymes,acid concentration and the liquid-solid ratio.The result showed that the optimal processing condition was eel bone immersing in 0.5 mol/L acetic acid for 28 hours at 37 ℃,and 0.10 g pepsin added,and the solid-liquid ratio was 1:45.The recovery of eel bone collagens was 80.80%.
