双孢蘑菇的冷冻干燥与高真空干燥

用冷冻干燥法和高真空干燥法分别对双孢蘑菇进行干燥，所得干制品在感官质量和复水性上无明显差别，但是，制品达到相同水分含量所需的干燥时间却有较大差别，高真空干燥法所需时间较短．实验证明，高真空干燥法非常适宜于多孔多纤维类物料（如蔬菜类产品）的干燥，并可在质量不受影响的前提下提高干燥效率．

THE FREEZE DRY AND VACUUM DRY OF MUSHROOM

The mushroom (Agaricus bisporus) is dried by the freeze dry and vacuum dry respectively and there are no obvious differences in the qualities of sensory and rehydration between the products. But, there are big differences of drying time when the same water content has been reached. The experiments show that the vacuum drying is suitable for drying the materials with many holes and fibers in its structure and the efficiency of dry is improved in the premise which has no effect on the quality of product.
