| 摘 要： | 采用稀释结合匀浆的方法以降低咸鸭蛋蛋清的粘度,再利用微滤法对其进行脱盐淡化处理.以咸鸭蛋蛋清液粘度为指标,通过单因素试验、正交试验确定最优前处理工艺,结果表明：咸鸭蛋蛋清脱盐淡化前处理最优工艺条件为：料液比1∶4,匀浆时间120 s,匀浆转速12000 r/min,在此条件下,咸鸭蛋蛋清混合液粘度为9 mPa·s,粒度为24 μm.以微滤脱盐率为指标,通过单因素试验、正交试验确定最优处理工艺,结果表明：微滤压差0.12 NPa,微滤4次,微滤时间120 min,在此条件下,咸鸭蛋蛋清脱盐率达92.43％,蛋白质截留率78.5％.

| Abstract: | In order to make full use of egg white of salted duck eggs and reduce the pollution to the envi- ronment, and obtain more economic benefits. This article explores an easy and practical method to emphasize on the desalination techniques of salted duck egg white （SDEW） for its comprehensive utilization. The results showed that the best pretreatment of microfiltration for desalination of SDEW involves a method with material to liquid of 1 ： 4, homogenization time for 120 s, and homogenization rate at 12000 r/min. The viscosity and particle size of SDEW were 9 mPa · s and 24 μm, respectively. The best process of mierofiltration was as following： 0. 12 MPa of pressure difference, microfihration for 4 times, and the duration for microfihration is 120 min. Under these conditions, the desalination rate and retention rate of proteins of SDEW reached 92.43% and 78.5%, respectively. |
