Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name REBAUDIOSIDE A.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Rebaudioside A

Rebaudioside A is a rebaudioside that is rubusoside in which the hydroxy groups at positions 3 and 4 of the beta-D-glucopyranosyloxy group at the 13alpha position have both been converted to the corresponding beta-D-glucopyranoside. It has a role as a sweetening agent. It is a rebaudioside and a beta-D-glucoside. It is functionally related to a rubusoside and a beta-D-Glcp-(1->2)-[beta-D-Glcp-(1->3)]-beta-D-Glcp. — ChEBI
