Principle
Total Migration
The sample is soaked in the solution which is chosen to simulate different foodstuffs. When the solution isevaporated and dried, the total migration amount of non-volatile matter can be obtained.
Non-volatile Matter
The sample is soaked in a solution as required by the various standards. After the soaking solution and blank solution are evaporated and dried, the total weight of non-volatile residue is obtained by comparing with the blank solution.
