Method for converting blood sugar stabilizing resistant starch in food materials

The invention relates to the field of starch conversion, in particular to a method for converting blood sugar stabilizing resistant starch in food materials, which comprises the following steps: raw material pretreatment, raw material crushing treatment, sedimentation treatment, starch liquid screening and drying treatment and conversion treatment. In the conversion treatment process, a surfactant is added before the enzymolysis process of the compound enzyme and the solution, the total mass ratio of the surfactant to the solution is 1: 0.3, a stabilizer containing metal ions is added in the enzymolysis process, and the total mass ratio of the stabilizer to the solution is 1: 0.03. According to the method, a sodium hydroxide solution is adopted for preparation in the potato raw material conversion process, so that the stability of subsequent soaking treatment of potatoes is improved, meanwhile, a low-temperature system is adopted for assisting sedimentation, and after repeated sedimentation treatment of disti
