Non-chemical preparation process of high-resistance starch based on waxy corn starch

The invention discloses a non-chemical preparation process of high-resistance starch based on waxy corn starch. Comprising the following steps: (1) soaking a waxy corn raw material; (2) scanning and screening waxy corn and common corn through an infrared spectrum; (3) optimizing a waxy corn preparation process; (4) analyzing a waxy corn starch production technology; wherein in the waxy corn preparation process optimization step, an optimization device for waxy corn starch preparation is adopted, the optimization device comprises a shell, a storage barrel is fixed above the shell through a support, and an intermittent guide mechanism capable of intermittently discharging waxy corn raw materials is arranged below the inner side of the storage barrel. The device is provided with the extrusion mechanism, so that waxy corn pulp on the inner side of residues can be effectively recycled, the yield of waxy corn starch is increased, and the phenomenon that a filter screen is blocked in the long-term use process is avo
