中文摘要:
      以水代法提取核桃油形成的乳化油为研究对象，利用水浴加热并离心的方法使其破乳，在单因素实验基础上采用响应面法对破乳工艺条件进行优化。结果表明：在加热温度90℃、加热时间40 min、离心时间20 min、离心机转速5 000 r/min的条件下，核桃乳化油破乳率为99.8%。
英文摘要:
      The emulsified oil formed in the aqueous extraction of walnut oil was demulsified by the methods of water bath heating and centrifugation，and the demulsification conditions were optimized by response surface methodology on the basis of single factor experiment.The results indicated that the optimal demusification conditions were obtained as follows：heating temperature 90℃，heating time 40 min，centrifugation time 20 min, centrifuge speed 5 000 r/min. Under these conditions，the demulsification rate of emulsified walnut oil was 99.8%.
