Abstract:
      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%.
