Patent number: 8257948Abstract: Glucosyl stevia compositions are prepared from steviol glycosides of Stevia rebaudiana Bertoni. The glucosylation was performed by cyclodextrin glucanotransferase using the starch as source of glucose residues. The short-chain glucosyl stevia compositions were purified to >95% content of total steviol glycosides. The compositions can be used as sweetness enhancers, flavor enhancers and sweeteners in foods, beverages, cosmetics and pharmaceuticals.Type: GrantFiled: February 17, 2011Date of Patent: September 4, 2012Assignee: PureCircle USAInventor: Avetik Markosyan
