| 摘 要： | 本研究利用五因素五水平二分之一实施正交旋转组合试验设计方法,研究了挤压系统参数(模孔长度、模孔直径、套筒温度、螺杆转速、物料水分)对干法挤压膨化带壳菜籽制油工艺中制得的压榨菜籽油的酸价、过氧化值(POV)的变化规律进行了研究。结果表明,干法挤压膨化预处理工艺参数对菜籽油的酸价、过氧化值有一定的影响。与传统工艺制得压榨菜籽油进行比较,结果表明,从榨笼中挤出的菜籽油酸价、过氧化值明显低于传统压榨菜籽油。油脂品质超过四级压榨油,接近三级压榨菜籽油。

| Abstract: | By using the dry method, the change in the law of acid value, peroxide value of rapeseed oil from extruding rapeseed was investigated by using a one-half orthogonal rotatable composite experimental design, which was based on five levels of five variables (nozzle length, die diameter, barrel temperature, screw speed diminishing, feed moisture content). The results showed that the acid value, peroxide value was influenced by the preliminary process parameters of dry method extrusion system. The acid value and... |
