Preparation method of jellyfish shoulder plate collagen

The invention particularly relates to a preparation method of jellyfish shoulder plate collagen, and belongs to the technical field of biology. According to the preparation method disclosed by the invention, the salted jellyfish shoulder plate is taken as a main raw material, the non-denatured collagen is extracted by taking lactic acid as an extracting agent under a low-temperature condition, and the acid-soluble collagen with relatively high purity is obtained, so that the utilization rate of the jellyfish can be effectively increased, the high-value utilization of the low-value jellyfish is realized, and a new thought is provided for the preparation of the collagen. 本发明具体涉及一种海蜇肩板胶原蛋白的制备方法，属于生物技术领域。本发明制备方法以盐渍海蜇肩板为主要原料，通过低温条件下以乳酸为提取剂提取非变性的胶原蛋白，得到较高纯度的酸溶性胶原蛋白，能有效提高海蜇的利用率，实现低价值海蜇高价值利用，为胶原蛋白的制备提供新思路。
