Method for extracting calamary health-care melanin

The invention discloses a method for extracting calamary health-care melanin. The method includes the steps that firstly, calamary ink sacs are smashed and subjected to one time of rough filtering, two times of filtering through cellulose filtering membranes with different apertures and primary spraying drying to obtain dry powder; secondly, after being dissolved, the dry powder is subjected to two times of separation chromatography and spraying drying, and finally a health-care melanin product is obtained. Compared with the prior art, the adopted method is simple in process and mild in conditions, enlarged production is easy, organic solvents are not used in the production process, and the extracted melanin is complete in natural structure and fills in domestic gaps. The high-additional-value product, namely melanin, is produced by means of calamaries, so product additional value is improved, and social and economic benefits are remarkable. 本发明提出种提取枪乌贼保健功能性黑色素的方法，所述提取方法首先将枪乌贼墨囊进行破碎处理，再经过次粗滤、两次不同孔径的纤维素滤膜过滤以及第
