Embodiment 1
[0013] Example 1: Prepare the product with shrimp shells as the raw material. First, dry the shrimp shells at 85-90° C., then crush the dried shrimp shells to 40-80 mesh, put them into the enzyme-cutting tank, and put them in the enzyme-cutting tank. Add 3.5 times of water and stir for 30-60 minutes, let stand at room temperature to swell for 1-2 hours; then, heat the enzymatic cutting tank to 51-55°C, according to the weight of the input shrimp shell powder raw material, the weight percentage is 0.6% For example, add mixed enzymes, adjust the pH value to 6.5-7.5, stir for 2 to 4 hours, and filter with a plate and frame filter press to obtain the refined enzyme-cut filtrate and clean shrimp shell powder; centrifuge the refined enzyme-cut filtrate, The upper liquid is crude oil, and the remaining liquid in the lower layer is hydrolyzed protein liquid. After decolorization and second fine filtration, it is desalted on a Sephadex G-10 column, then concentrated in a vacuum and spra...
