Title:
METHOD FOR PREPARING ARROWHEAD RESISTANT STARCH BY ULTRASOUND SYNERGISTIC PULLULANASE
Document Type and Number:
WIPO Patent Application WO/2021/114694
Kind Code:
A1
Abstract:
Provided is a method for preparing arrowhead resistant starch by ultrasound synergistic pullulanase, wherein the method comprises the following steps: (1) cleaning and arranging the arrowhead; (2) extracting starch from the arrowhead; (3) preparing the resistant starch; (4) performing enzymolysis in an ultrasonic field, and freeze-drying to obtain the arrowhead resistant starch. In the preparation process of the arrowhead resistant starch by the pullulanase method, the method accelerates the movement of solvent molecules through the cavitation and mechanical vibration of the ultrasonic wave, and solves the problem of low enzymatic hydrolysis reaction efficiency in the preparation process of the resistant starch by the enzymatic method.
