Method of purifying collagen

摘要: PURPOSE: To obtain high-purity collagen in high yield, by extracting and removing substances except from collagen-containing animal tissue with a dilute alkali solution having ≤ given concentration, to remove non-collagen substance efficiently. CONSTITUTION: Collagen-containing obtained grinding or fine crushing common device method is blended ≤1.0 N, preferably ≤0.5 stirring, shaking, etc. NaOH, KOH, etc., are used as the alkali. Non-collagen extracted blending treatment removed, give an extraction residue. The carried out at room temperature usually. When unmodified purified, condition not denature heat required.
