Abstract: When we processed cephalopod, large amounts of byproducts were produced, most of which have been dumped as waste or processed into feed, causing huge waste of resources. The ink sac in byproducts accounts for about 1.3% of the total weight of cephalopod. In this paper, the physiochemical properties of the ink sac melanin from cephalopod were analysed firstly. And some common extraction methods of ink sac melanin, including high speed centrifugation method, acid or alkaline hydrolysis method, enzyme hydrolysis method and alkali solution-acid isolation method were introduced. Furthermore, the bioactivities of ink sac melanin, such as enhancing immunity, antitumor activity, antioxidant activity were reviewed. All in all, the exploration of ink sac melanin would provide reference for high value application of the cephalopod ink sac and the development of marine medicine.
