高温处理对食用调和油微波介电特性与品质的影响（Effect of High-temperature Heat Treatment on Microwave Dielectric Properties and Qualities of Mixed Edible Oil）
调和油 高温处理 相对介电常数 介质损耗因数
2010/12/29
以食用调和油为研究对象，采用同轴探头技术测量了高温处理（120～240℃，3～15h）后调和油在200～4500MHz的微波介电特性和品质指标。结果表明：未处理调和油的相对介电常数ε′r和介质损耗因数ε″r随频率的变化而变化，经高温处理后ε′r和ε″r基本不随频率改变。与未受高温处理相比，处理使同频率下调和油的ε′r减小，ε″r增大。高温处理的温度、时间对介电参数值有一定的影响。当温度大于18...
