正交试验优化冷榨红花籽油脱色工艺

Optimization of Decoloration Process of Cold Pressed Safflower Seed Oil by Orthogonal Test

通过正交试验优化红花籽油吸附脱色工艺,确定最佳工艺条件:白土活性炭混合脱色剂添加量5%,脱色温度80℃,脱色时间30 min。在优化后的最佳工艺条件下进行红花籽油吸附脱色,冷榨红花籽脱酸油在457 nm处的吸光度由0.541降低到0.244,脱色率约为54.90%。

Safflower seed oil absorbent decoloration process was optimized by the orthogonal test.The optimal technological conditions were determined as follows:clay mixed decolorizing agent 5%,active carbon decoloring temperature 80℃,decoloring time for 30 min.The absorption and decoloration of safflower seed oil were carried out under the optimal process conditions.The absorbance of cold pressed safflower seed deacidification oil at 457 nm was decreased from 0.541 to 0.244,and the decoloration rate was about 54.90%.
