The invention discloses a method for preparing sugar spice for cigarettes by using high-pressure homogeneity. The method comprises the following steps: S1, preparing sugar spice in advance: weighing and mixing required raw materials according to a proportion, and then stirring at normal pressure until feed liquid is basically uniform; S2, enabling the feed liquid of the sugar spice, which is prepared in advance in the S1, to pass through a high-pressure homogenizing valve, and controlling the temperature of the feed liquid to be 50 DEG C or below 50 DEG C; adopting a mode of one-stage or multi-stage high-pressure homogeneity combination; keeping the pressure of the high-pressure homogenizing valve to be 60MPa-100MPa, and circulating until uniformly blending mixture; S3, enabling the feed liquid to pass through a microfiltration membrane with an aperture of 0.1-5 microns; and S4, cooling the finished sugar spice for cigarettes to room temperature, and then sealing and filling. The method has the following beneficial effects: the sugar spice for cigarettes can keep a uniformly suspended state within 12-month storage time, the phenomena of stratified precipitation, bucket swelling, deterioration and the like cannot happen, and the quality of the sugar spice is protected well.
