Embodiment Construction
[0007] The present invention uses frozen Antarctic krill as raw material, takes Antarctic krill out of the refrigerator, pulverizes and homogenizes it with a homogenizer, and adds 1 to 2% of the enzyme activity of 80,000 U / g to the homogenate. Papain, for example, add 1.5% papain by mass percentage to the homogenate with an enzyme activity of 80,000U / g, and the reaction temperature after adding papain should be controlled between 50°C and 60°C, for example, the reaction temperature should be controlled at 58°C ℃, and stir during the reaction process. The stirring reaction is controlled between 3h and 5h to accelerate the enzymolysis reaction. After the enzymolysis is completed, boil for 15min to inactivate the enzyme activity. The liquid phase A and precipitate B are prepared by centrifugation; The precipitate B was dissolved into a suspension by adding an equal volume of water, and the suspension was filtered with a 300-mesh sieve to obtain a suspension C and a residue D, and ...
