摘　　要：以提高双孢蘑菇干制品质量为目的,采用自行设计的小型气调干燥实验设备,用CO2、N2气体置换干燥室空气作为介质对双孢蘑菇片进行气调干制试验。分析了气调与热风干制对双孢蘑菇片干燥速度和制品质量的影响。结果表明:双孢蘑菇片采用充N2降O2干制的干制品维生素C保存率得到较好保存,纤维化进程慢,褐变度低,更接近鲜菇固有的风味和品质。In order to improve the quality of dried Agaricus biporus slices, a small modified atmosphcric dryer developed by the authors was used to conduct the experiment for the slices of Agaricus biporus, in which CO2, N2 were used as drying media to replace partial air. The effect of Controlled Atmosphere Drying (CAD) and hot air drying on the drying speed and product quality of the dried products was analyzed. The results showed that the slices of Agaricus biporus with CAD in drying process filling N2 to replace partial air not only the highest drying rate could be obtained, but also could get the mass fraction of vitamin C was better, the mass fraction of ADF was losing, and could obviously reduce browning degree, the fiavour and quality of the Agaricus biporus were satisfactory.
