摘　　要：采用"填料型"冷电弧装置对大枣多糖溶液进行了脱色研究。在单因素实验的基础上进行正交实验,确定最佳工艺条件。结果表明:填充有平均粒径3.01mm活性氧化铝的冷电弧装置,当糖液质量浓度为50g/L时,在18kV的电压下脱色30min,脱色效果最好,脱色率为57.0%,糖损失率为9.82%。The decolorization of jujube-polysaccharides studied.Base on the single factor experiment, using the conditions.The results showed that use the non-thermal p the polysaccharide solution concentration was 50g/L, in decolorization rate 57.0%,1oss rate of sugar 9.82%. by packing media type of non-thermal plasma was orthogonal design to determine the optimum process asma device fill with activated alumina（φ3.01mm） ,while the voltage tSkV detreated 30min, decoloration best,
