PURPOSE:To obtain a sweetener having improved taste without lowering of degree of sweetness, by using alpha-glycosylsteviol glycoside obtained by the action of cyclodextrin glucosyltransferase as a raw material. CONSTITUTION:A glucose is subjected to alpha-addition to a steviol glycoside using cyclodextrin glucosyltransferase at 4-7, preferably 5-6pH at 30-60 deg.C, preferably 40-50 deg.C to give alpha-glucosylsteviol glycoside, which is treated with beta- amylase or glucoamylase at 4-7, preferably 5-6pH at 30-60 deg.C, preferably 40-50 deg.C. |
