| titleOfInvention | Preparation method and use of soluble squid ink melanin |
| abstract | The invention discloses a preparation method of soluble squid ink melanin. The preparation method comprises the following steps of: 1) washing ink suspension in the ink sac of a squid with ice water at the temperature of 0-4 DEG C, centrifugating and then removing supernatant fluid to obtain a precipitate; 2) performing vacuum freeze-drying on the precipitate obtained in the step 1) to obtain an insoluble melanin crude product; 3) dissolving the insoluble melanin crude product in alkali liquor and performing ultrasonic processing for 30-90 minutes, wherein the material-liquid ratio of the insoluble melanin crude product to the alkali liquor is 1g of the insoluble melanin crude product/20-80ml of the alkali liquor, and the alkali liquor is an NaOH solution in the molar concentration of 0.1-1.0mol/L; and 4) centrifugating the product obtained in the step 3), taking the supernatant fluid and performing vacuum freeze-drying to obtain the soluble squid ink melanin. The invention further provides a use of the soluble squid ink melanin as an antioxidant. |
