| 摘 要： | 用截留分子量1万的无机陶瓷膜在45℃、0.15 MPa下超滤大豆混合油,研究了膜通量与浓缩比的关系.超滤脱胶结果表明,超滤可以脱除95.78%的大豆磷脂,同时超滤脱胶油的色泽和毛油色泽相比,明显变浅,但是酸值升高.超滤还可以截留大豆油中的Ca、Mg、Fe和Cu等金属元素.

| Abstract: | The soybean miscella was ultrafiltrated by inorganic ceramic membrane with molecular weight cut off (10 000) dalton,and the relationship between the flux of membrane and the volume concentration ratio was investigated.The results showed that 95.78% of phospholipid was removed during the ultrafiltration.Moreover,some pigments in the crude soybean oil were removed by the ultrafiltration,which caused the light color in the degummed oil.Meanwhile,the retention of some metal element,such as calcium,magnesium,iron and cuprum,were observed. |
