| 中文摘要: |
| 研究了亚临界丁烷萃取棉籽油的工艺条件，并对产物品质进行检测分析。在单因素试验的基础上采用Box-Behnken响应面试验设计优化工艺参数。得到亚临界丁烷萃取棉籽油的最优工艺参数为：萃取温度47℃，萃取4次，每次萃取时间36 min，棉籽仁粉碎过60目筛；在最优工艺参数条件下，萃取率达到93.1%。结果表明，亚临界丁烷萃取的棉籽油品质好，可以降低精炼成本，经济效益好。 |
| 英文摘要: |
| The process condition of subcritical butane extraction of cottonseed oil was studied，and the quality of the product was detected and analyzed.The Box-Behnken response surface design was employed to optimize the process condition on the basis of single factor experiment.The optimal process parameters of subcritical butane extraction of cottonseed oil were obtained as follows：extraction temperature 47℃,extraction times 4, extraction time 36 min, particle size 60 meshes.Under these conditions，the extraction rate was 93.1%.The results indicated that the quality of the cottonseed oil extracted by subcritical butane was better，resulting in a reduction of refining cost and better economic benefit. |
