The invention discloses a novel targeted enzymolysis process for squid processing by-products. The process comprises the following process steps: S1, pulping the squid processing by-products, and adding distilled water; S2, heating the slurry; S3, adding protease into the slurry, wherein the protease comprises acid protease, alkaline protease, pepsin, papain and trypsin; S4, carrying out enzyme deactivation on the slurry; S5, carrying out centrifugal purification on the slurry to obtain a supernatant; and S6, performing ultrafiltration on the supernatant by adopting a hollow fiber column membrane to obtain a polypeptide liquid. According to the method, the squid processing by-products are processed by adopting a targeted enzymolysis technology, so that bioactive peptide convenient for infants to absorb is obtained, and redevelopment and reutilization of the squid processing by-products are realized. 本发明公开了一种用于鱿鱼加工副产物的新型靶向酶解工艺，包括有以下工艺步骤：S1、对鱿鱼加工副产物进行打浆，添加蒸馏水；S2、对浆液进行加热；S3、向浆液添加蛋白酶，所述蛋白酶包括有酸性蛋白酶、碱性蛋白酶、胃蛋白酶、木瓜蛋白
