长牡蛎可溶性黑色素的脱盐研究

该研究是继天然长牡蛎(Crassostrea gigas)黑色素的提取、可溶性长牡蛎(Crassostrea gigas)黑色素的制备之后,对牡蛎黑色素提纯方面的进一步拓展和延伸。运用半透化学材料分离的方法,选取纳滤透析膜为分离介质,对可溶性长牡蛎黑色素的制取产物中多余的盐类无机物进行分离剔除,进而得到纯度较高、品质优良的可溶性长牡蛎黑色素晶体,通过称质量和盐度测量,计算得出该方法对黑色素脱盐率达到98%,证明了该方法可以进行贝类黑色素的脱盐处理工作。

Desalination study of soluble melanin of the Pacific oyster

This study is the further development and extension of the technology of melanin purification after the extraction of natural and soluble Pacific oyster melanin. The method of permeable membrane separation was applied using a nanofiltration membrane as the medium for separating the redundant salts from the crude melanin of the oyster. Then, the soluble melanin crystal of the Pacific oyster was obtained with a higher purity and quality. We observed that the desalination rate of melanin calculated using weight and salinity reached up to 98%. Therefore, this method can be used for desalination of mollusk melanin.
