Abstract
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.

1-20. (canceled)
A flavor modifier composition comprising a glucosyl stevia composition made by a process comprising the steps of:
- adding starch into water to form a starch suspension;
- adding a first hydrolyzing enzyme comprising a mixture of α-amylase and CGTase into the starch suspension and incubating for about 0.5 to 5 hours at about 70-90° C., resulting in a liquefied starch suspension;
- inactivating the α-amylase by low pH heat treatment;
- adding steviol glycosides into the liquefied starch suspension, resulting in a reaction mixture;
- and
- adding a transglucosylation enzyme into the reaction mixture and incubating for about 24-48 hours at about 65° C. to transglucosylate the steviol glycosides, resulting in a glucosyl stevia composition;
- wherein the glucosyl stevia composition comprises unmodified steviol glycosides and greater than about 34% by weight di-, tri- and tetraglucosyl steviol glycosides.
