| 中文摘要: |
| 研究了铁核桃油膜法脱胶工艺及其对铁核桃油品质的影响。分别采用Plackett-Burman实验和响应面实验对铁核桃油膜法脱胶工艺进行优化。结果表明：铁核桃油膜法脱胶的最佳工艺条件为膜孔径10 kDa、溶油比3∶?1、操作压力0.25 MPa，在此条件下膜法脱胶后铁核桃油中磷脂含量从755.603 mg/kg降为16.25 mg/kg，脱胶率为97.85%。与水化脱胶相比，膜法脱胶后铁核桃油中VE和植物甾醇的含量高，氧化诱导时间长。 |

| The membrane degumming process of Juglans sigillata oil and its influence on quality of Juglans sigillata oil were studied. Plackett-Burman experiment and response surface methodology were used to optimize the membrane degumming process of Juglans sigillata oil. The results showed that the optimal membrane degumming conditions were obtained as follows: membrane pore size 10 kDa, ratio of solvent to oil 3∶?1 and operation pressure 0.25 MPa. Under the optimal conditions, the content of phospholipids in Juglans sigillata oil decreased from 755.603 mg/kg to 16.25 mg/kg, and the degumming rate was 97.85%. Compared with water degumming,the contents of VE and phytosterols in Juglans sigillata oil after membrane degumming were higher and the oxidation induction time was longer. |
