METHOD FOR THE INACTIVATION OF AMYLASE IN THE PRESENCE OF PROTEASE |
摘要 |
The invention relates to a method for the inactivation of amylase in a solution comprising Rhizomucor miehei aspartic protease by keeping the solution at a pH between 2.1 and 2.8 and at a temperature between 20 DEG C and 40 DEG C for a period of time sufficient to inactivate amylase for at least 95 %.With this method the level of residual Rhizomucor miehei aspartic protease activity in the solution at the end of the heating time is at least 90 %, preferably at least 95 %, and the residual amylase activity is 0.05 RAU/g or lower, more preferably 0.001 RAU/g or lower, i.e. more than 99% of the amylase activity has been inactivated. |
