Abstract
The invention discloses a method for preparing an amomun kravanh volatile oil microcapsule by using ultrasonic and belongs to the field of food processing. The method is characterized by comprising the following steps of: firstly, adding beta-cyclodextrin serving as a wall material into hot water to prepare a beta-cyclodextrin aqueous solution, and stirring until the beta-cyclodextrin is dissolved totally for later use; secondly, adding amomun kravanh volatile oil serving as a core material into the solution while stirring, and homogenizing to obtain emulsion; thirdly, putting the emulsion into ultrasonic equipment for performing ultrasonic operation; and finally, refrigerating, extracting, filtering, freezing and drying to obtain an amomun kravanh volatile oil microcapsule product. The amomun kravanh volatile oil microcapsule prepared by using the method is solid powder; by the method, the amomun kravanh volatile oil can be separated from outside air, so volatilization of the amomun kravanh volatile oil is avoided and the preservation time of the amomun kravanh volatile oil can be prolonged effectively; and furthermore, the preparation for the amomun kravanh volatile oil microcapsule by using the ultrasonic is simple, quick and feasible.
