Abstract: Three methods(ultrasonic method,high pressure homogenization and freezing-thaw disruption) were used to disrupt Spirulina cell respectively,in order to find out the optimal cell disruption conditions to increase the dissolution rate of Spirulina phycobiliprotein(SPP).Results showed that the highest dissolution rates of the SPP are 71.25%,73.87% and 72.03%,under the optimal conditions of ultrasonic method,high pressure homogenization and freezing-thaw disruption,respectively.

Key words: Phycobiliprotein, ultrasonic, high pressure homogenization, freezing-thaw, protein dissolution rate
