摘要: 目的:研究酸种类、酸添加量、加水量、脱胶温度、搅拌时间对山毛豆毛油脱胶率的影响。方法:在单因素试验基础上,利用响应面分析法对山毛豆毛油脱胶工艺进行优化。结果:得到山毛豆酸辅助脱胶最佳工艺条件为磷酸添加量2.47g/kg、加水量4.1%、脱胶温度62℃、搅拌时间45min。该条件下山毛豆毛油脱胶率为92.48%,与模型预测值91.5256%接近,脱胶山毛豆油中磷脂含量为0.095%。结论:磷酸辅助脱胶技术可对山毛豆毛油中的磷脂进行有效脱除。

Abstract: Objective: To optimize process conditions for the degumming of Tephrosia.vogelii Hook f. seed oil such as acid kind and amount, water amount, temperature and stirring time for maximizing degumming rate. Methods: On the basis of single factor experiments, phosphoric acid amount, water amount, temperature and stirring time were optimized by response surface analysis. Results: Phosphoric acid was found to be the best degumming agent for T.vogelii Hook f. seed oil. The optimum degumming conditions were determined as follows: stirring at 62 ℃ for 45 min in the presence of 2.47 g/kg phosphoric acid and 4.1% water. Under these conditions, the actual degumming rate was 92.48 % (the degummed oil contained 0.095% phosphatide), close to the predicted value of 91.5256%. Conclusion: The phosphoric acid aided degumming process can effectively remove phospholipid from T.vogelii Hook f. seed oil.
