摘　　要：利用WS/08—01型调温调湿试验装置,测得枸杞在温度为25℃、相对湿度为10%～90%范围内的吸湿和解吸平衡含水率数据,获得在该温度下的吸湿和解吸等温线,找到了枸杞干果的安全贮藏条件。试验结果表明:在环境湿度较大和枸杞含水率较高时,出现霉变现象;当湿度下降和枸杞含水率下降时,霉变随之减弱;当枸杞总水分含量大于40%时,出现霉变现象;空气相对湿度大于70%时,霉变现象严重。In this paper,WS/08-01-type thermostat humidity-box testing device,the measured temperature of wolfberry 25 ℃,relative humidity of 10-90% within the scope of the rate of moisture absorption and desorption equilibrium moisture content data obtained at the temperature of the moisture absorption and desorption isotherms,and found the safety of Chinese wolfberry dry fruit storage conditions.The results showed that：in the environmental humidity and moisture content of wolfberry is high,the phenomenon appears mildew.When the humidity down and the moisture content decreased medlar,mildew along weakened.When the Chinese wolfberry is greater than 40% of the total water content when the phenomenon occurs mildew.Air relative humidity greater than 70% of the phenomenon of severe mildew.
