Food Standards Australia New Zealand (FSANZ) on June 29th, 2015 issued a draft notification that proposes the addition of rebaudioside M to the list of permitted steviol glycosides in response to a submission made by PureCircle Limited.
In accordance with their regulatory process FSANZ now solicits comments/submissions that will assist in the final decision, with an expected final approval by approximately March 1, 2016.
