摘要
研究酸种类、酸添加量、水添加量、酸处理温度、酸处理时间对菜籽毛油脱胶效果的影响。在单因素试验基础上,利用响应面分析法对菜籽毛油酸法脱胶工艺进行优化。优化的工艺条件为:酸处理温度60℃,50%柠檬酸添加量0.22%(占油质量),水添加量3.34%(占油质量),酸处理时间24.78 min。在优化条件下,脱胶菜籽油磷含量为15.67 mg/kg,脱胶率达93.76%,与模型预测值14.70 mg/kg,脱胶率94.15%很接近。
Effects of acid kind and dosage, water dosage, acid reaction temperature and time on degum- ming of crude rapeseed oil were investigated. On the basis of single factor experiment, the degumming conditions of crude rapeseed oil were optimized by response surface methodology. The optimal degumming conditions were determined as follows ： acid reaction temperature 60 ℃, acid reaction time 24.78 min, citric acid （concentration 50% ） dosage 0.22% （based on the mass of crude rapeseed oil）and water dos- age 3.34% （based on the mass of crude rapeseed oil）. Under these conditions, the phosphorous content of degummed quite close to rapeseed oil reduced to 15.67 mg/kg and the degumming rate was 93.76%, which were the predicted value of 14.70 me./kz and 94.15%
