Abstract:
1. A process for producing a sweetener, comprising: dissolving starch into water to form a starch suspension; adding a first batch of CGTase into the starch suspension and incubating for 0.5 to 2 hours at 75-80° C., resulting in the liquefaction of starch; adding a purified adding a second batch of CGTase into the reaction mixture and incubating for 12 to 48 hours at 55-75° C.; adding sucrose into the reaction mixture and incubating for 2 to 10 hours at 65-75° C. to form fructose-terminated oligosaccharides; removing malto- or fructose-terminated oligosaccharides; and concentrating and drying to obtain the glycosylated sweetener wherein the glycosylated sweetener is with the most superior sweetness quality and more than 170 of relative sweetness to 5% of sucrose.
