Claim Text:
1. A process for making a glucosyl stevia composition, comprising the steps of: (a) adding starch into water to form a starch suspension; (b) adding a first hydrolyzing enzyme selected from the group consisting of CGTase, α-amylase, β-amylase, and mixtures thereof, into the starch suspension, and incubating at a temperature of about 70° C. to 90° C. for about 0.5 to about 5 hours, resulting in a liquefied starch suspension; (c) inactivating the first hydrolyzing enzyme by low pH heat treatment; (d) cooling the liquefied starch suspension and adjusting the pH to about 5.5 to 7.0; (e) adding steviol glycosides into the liquefied starch suspension, resulting in a reaction mixture; and (f) adding a transglucosylation enzyme into the reaction mixture and incubating for about 12 to 48 hours at about 55-75° C. to transglucosylate the steviol glycosides, resulting in a glucosyl
