| Abstract: | The fraudulent addition to milk is usually occurred with the rapid development of dairy industry. Fast analysis of protein fraction and detection of adulterations in the milk can be done by capillary electrophoresis. Capillary electropherograms of raw milk, pasteurized milk and UHT milk were gained by capillary electrophoresis. The casein to total protein ratio(%) in different sample was calculated by 32 Karat Software. The SDS-CGE electropherograms of samples of milk powder containing different quantity soya protein were also gained in this paper. The advantages of this method are fast, efficient, less sample needed and economic. |
