Abstract
A method for producing a cold-water-soluble starch. The method includes: 1) adding a starch and 3-45 wt. % of an ethanol aqueous solution to a container, and stirring a mixture of the starch and the ethanol aqueous solution in the container, thus yielding a starch-ethanol-water; 2) introducing the starch-ethanol-water to an extruder and producing a noodle extrudate, where the extruder comprises 3 continuous temperature control areas: a first area having a temperature of 50° C., a second area having a temperature of between 95 and 120° C., and a third area having a temperature of 60° C.; a rotation speed of the extruder is 70-150 rpm; and the noodle extrudate has a diameter of 0.2-0.5 cm; 3) pressing and roll slitting the noodle extrudate, thus yielding a plurality of slices; and 4) drying the plurality of slices in a microwave vacuum oven, cooling, and pulverizing the plurality of slices.
