The invention discloses a method for preparing preserved fruits. The method comprises the following steps: (1) taking fruits, carrying out vacuum microwave drying on the fruits until the water content of the fruits is 40-60wt% and softening the fruits; (2) soaking the softened fruits in a primary sugar permeable solution to be subjected to primary sugar permeating and seasoning under vacuum; (3) carrying out secondary sugar permeating and seasoning under vacuum on the fruits subjected to primary sugar permeating and seasoning under vacuum; and (4) fishing out and draining the fruits treated in the step (3) and then drying the fruits in an oven until the water content of the fruits is lower than 20%, thus obtaining the preserved fruits. The method has the following advantages: the preserved fruits are prepared by vacuum microwave softening treatment and two-time sugar permeating under vacuum, thus not only shortening the processing period, saving energy and reducing consumption, but also ensuring the obtained preserved fruits to have the advantages of uniform color, certain transparency and good extrinsic shape.
