The invention discloses dried peach slices and a making technique thereof. The making technique of the dried peach slices specifically comprises the following steps that firstly, selected peaches are peeled, washed and sliced and then are placed in a color fixative for color protection, the surfaces of peach slices are washed with distilled water, and water on the surfaces of the peach slices is removed through absorption; secondly, the peach slices are placed in a constant-temperature table for oscillation, sugar infusion and dewatering, the surfaces of the peach slices are washed with distilled water, and water on the surfaces of the peach slices is removed through absorption; thirdly, microwave-assisted drying is conducted, so that semi-finished products are obtained, and then the dried peach slices are obtained by conducting drying with hot air. According to the dried peach slices and the making technique thereof, by the adoption of the penetration, dewatering and assisting microwave and hot air combined drying method, drying time can be shortened, production cost is reduced, Vc in the peach slices is effectively reserved, and the texture quality of the peach slices is good. According to the method, operation is easy and effective, cost is low, efficiency is high, application and popularization are facilitated, the method is suitable for large-scale production and application, and the application prospect is broad.
