摘　　要：以长白山地区山里红为原料,采用微波结合真空冻干方法处理样品。选取单因素试验、正交试验并结合感官评价的方法确定最佳干燥工艺条件。结果表明,当冷冻干燥时间为20 h,微波功率400 W,真空度60 Pa时,山里红干制品品质最佳。In this experiment,the Crataegus pinnatifida in Changbai Mountain area was used as the raw material.The samples were treated by microwave combined with vacuum freeze-drying.The best drying conditions were determined by single factor,orthogonal test and sensory evaluation.The results showed that when the drying time was 20 h,the microwave power 400 W,and the vacuum degree was 60 Pa,the quality of the Crataegus pinnatifida dry product was the best.
