摘要
为研究含水晶梨颗粒亲水性胶体溶液通电加热过程中,颗粒尺寸、颗粒体积分数、CMC-Na体积分数、胶体溶液质量分数和柠檬酸质量分数五因素对通电加热速度的影响,采用五因素二次正交旋转组合设计试验进行回归分析,建立了加热速度数学模型,对影响加热速度的工艺参数进行了优化,得到影响通电加热速度的工艺参数从大到小依次为:胶体溶液质量分数、CMC-Na体积分数、柠檬酸质量分数、颗粒尺寸、颗粒体积分数;影响加热速度的各工艺参数的最优组合:颗粒尺寸1.0 cm、颗粒体积分数30%、CMC-Na体积分数40%、胶体溶液质量分数4%、柠檬酸质量分数0.25%。
Influences of five factors which were size of pear particles,concentration of pear particles,ratio of potato starch to CMC-Na,concentration of colloidal solution and citric acid content respectively,on ohmic heating rate for colloidal solutions with fruit granules,as well as optimization process were studied.Heating rate models was established and optimized parameters were obtained by quadratic orthogonal rotation combination design with five factors and regression analysis.Results showed that effect order of five factors on ohmic heating rate is, according to priority, colloids concentration, ratio of potato starch to CMC-Na, citric acid content, size of pear particles, and concentration of pear particles; the optimal parameter is size of pear particles of 1.0 cm, pear particles concentration of 30 %, ratio of potato starch to CMC-Na of 40 %, colloids concentration of 4 % and citric acid content of 0.25%.
