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.

Abstract: The invention discloses a method for adsorbing ethylene gas using amorphous granular starch. The method firstly prepares amorphous granular starch, wherein starch slurry is prepared from starch with a ethanol aqueous solution and NaOH solution is added dropwise so as to react at 30 to 35° C. for 20 to 50 minutes; Then the slurry is centrifuged, neutralized with an ethanol hydrochloride solution, washed and dried to obtain the amorphous granular starch. The amorphous granular starch is placed in a high-pressure reactor and ethylene gas is introduced after the reactor is vacuumized to react at 0.8 to 1.5 Mpa and 20 to 30° C. for 15 to 25 h so that starch powder product adsorbing with ethylene is obtained. The test result shows that the content of ethylene in the obtained product can reach more than 30%. The method is simple, highly efficient and cheap for the adsorption process of ethylene, and the product is expected to be widely applied in the field of fruit and vegetable modified atmosphere preservation.
