Steviosides

FCC initially put forward the revision of the steviasides standard in December, 2011.  They received a lot of comments after that and then they came out with an easier method to separate and test all nine steviol glycoside in stevia leaves. USP has a monography on high purity Rebaudiodside A. Different kinds of steviosides products and steviosides mixtures have been used in a lot of products now. Researches show that the most critical task for the stevia manufacturers is to ensure the source of stevia raw material. Latest FCC suggests them use two new USP reference standards “Rebaudioside A and stevioside system analysis” to identify and monitor the unique stevia glycoside content.
