Abstract: Disclosed in the present invention are a starch-embedded aroma substance microcapsule and a preparation method therefor. The method comprises: performing degreasing treatment on starch, gelatinizing the starch at high temperature, sequentially adding aroma substances having different molecular sizes into the starch paste, and compounding at high temperature; and finally, cooling, centrifuging, washing, and drying to obtain an aroma substance microcapsule. The total embedding rate of the aroma substances in the obtained microcapsule can reach 46.64%. The present invention is simple and convenient in process, and easy in condition control, does not need large special equipment, and has low cost and high efficiency.
