摘要： 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.

摘要： The present disclosure discloses a simple preparation method of green acid-modified cyclodextrin, belonging to the field of cyclodextrin modification. Cyclodextrin and succinic acid are mutually modified by an esterification reaction in the presence of catalyst, and acid-modified cyclodextrin with different modification degrees is obtained by controlling reaction time at a high temperature or under a microwave action. The prepared modified cyclodextrin does not involve the use of toxic and harmful reagents, the modification reaction is simple, green and controllable, and the loading capacity of the modified cyclodextrin to guest molecules is remarkably improved compared with the loading capacity of the original cyclodextrin, so that the modified cyclodextrin has great application potential in the health fields such as food, medicines, and cosmetics.
