Rebiana is the trade name for high-purity rebaudioside A, a steviol glycoside that is 200 times as sweet as sugar.[1] It is derived from stevia leaves by steeping them in water and purifying the resultant extract to obtain the rebaudioside A
The Coca-Cola Company filed patents on rebiana, and in 2007 it licensed the rights to the patents for food products to Cargill; Coca-Cola retained the exclusive rights to use the patents for beverage products.[2] Truvia and PureVia are each made from rebiana and were each recognized as GRAS food ingredients by the US FDA in 2008
