摘要
通过对原有冷榨机进行改造用于榨取小麦胚芽油,通过在轴内通冷却水等措施,控制榨油机榨膛温度,通过单因素及二次正交旋转设计试验,确定榨膛温度75℃、小麦胚芽含水量7%、榨油机的榨膛压力3.6MPa,制得小麦胚芽油中VE含量为268.7mg/100g,磷脂含量为925mg/100g,小麦胚芽出油效率为32%。
A YJYⅡ-type cold press machine was modified and used for extraction of wheat germ oil from full-fat wheat.Pressure chamber temperature was controlled by taking measures such as cooling water injecting into the axis direction,etc.Response surface methodology based on a four-variable,five-level quadratic rotation-orthogonal combination design was employed to investigate the pairwise interaction effects of water content of the material,pressure chamber temperature and extraction pressure on vitamin E content of wheat germ oil.Results showed that the optimal values of the above parameters were determined as follows：water content of the material 7%,pressure chamber temperature 75 ℃ and extraction pressure 3.6 MPa.The product obtained under such conditions contained 268.7 mg of vitamin E/100 g and 925 mg of phospholipids of /100 g,with an extraction yield of 32%.
