The invention provides a high anthocyanin noodle, which takes purple sweet potato as the main raw material, can supplement anthocyanin, cellulose, amino acids, vitamins and other nutrients. In addition, the invention provides a making method of the high anthocyanin noodle. By means of acidic alcohol solution extraction, high concentration anthocyanin powder can be obtained, and the anthocyanin content of the noodle is also greatly improved; by means of super-fine comminution, the dissolution or degradation surface area of nutrients can be increased, dissolution of anthocyanin and dietary fiber, protein digestibility and starch digestibility can be greatly improved; and through high temperature standing after dough kneading, partial gelatinization of starch can be promoted, viscoelasticity of the dough is increased, noodle breaking during noodle rolling and forming can be reduced, and soup turbidity of the product is also reduced. The noodle provided by the invention has taste and other mechanical properties similar to those of commercially available ordinary fine dried noodles, and has anthocyanin content, water soluble dietary fiber content, protein and starch digestive performance superior to those of ordinary fine dried noodles.
