Abstract: The present disclosure provides a method for obtaining melanin from invertebrate biomass. The method may comprise rupturing the invertebrate biomass to form raw material; demineralizing the raw material to form a first solid fraction; deproteinating the first solid fraction to form a second solid fraction; liberating a melanin from the second solid fraction resulting in a supernatant comprising the melanin; extracting the supernatant; and precipitating the melanin. The present disclosure further provides a purified melanin obtained from invertebrate biomass.
