Shark cartilage preparation ( SCP) was extracted from shark cartilage by the method of guanidine hydrochloride extraction, acetone fractional precipitation, and ultrafiltration. 以鲨鱼软骨为原料,经盐酸胍抽提,丙酮分级沉淀,超滤等步骤得到鲨鱼软骨制剂(sharkcartilagepreparation,SCP)。
The result showed that fractional ultrafiltration separation can effectively separate sodium caseinate peptides. 结果表明,分级膜分离方法对酪朊酸钠水解液中的混和肽类能按照分子量大小进行有效的分离。
