Method for extracting sea cucumber polypeptide from sea cucumber viscera

The invention discloses a method for extracting sea cucumber polypeptide from sea cucumber viscera, the method comprises the following steps: drying the sea cucumber viscera, crushing into sea cucumber viscera powder, soaking and swelling the sea cucumber viscera powder, and performing water bath treatment to fully decompose raw materials and facilitate the release of contents in the sea cucumber viscera powder, then utilizing the technology of secondary enzymatic hydrolysis, overcoming the product inhibition effect, fully breaking the peptide bonds in the sea cucumber viscera, promoting conversion of proteins in the sea cucumber viscera into polypeptides, improving the extraction rate of the polypeptides in the sea cucumber viscera, and finally obtaining the sea cucumber polypeptides through impurity removal and freeze drying. 本发明公开了一种从海参内脏中提取出海参多肽的方法，该方法将海参内脏烘干后粉碎成海参内脏粉末，海参内脏粉末浸泡溶胀后经水浴处理，可让原料充分分解，有利于海参内脏粉末中内容物的释放，再利用二次酶解技术，克服产物抑制效应，使得海参内脏中的肽键充分断裂，促进海参内脏中的蛋白质转化成多肽，提高了海参内脏中多肽的提取率，最后通过除杂及冷冻干燥后制得海参多肽。
