PURPOSE: To provide a food sweetener having functions to prevent growth of decayed teeth and to protect teeth by mixing a specified proportion of galactose into a food sweetener essentially comprising sucrose. CONSTITUTION: A whey containing no protein or a whey from which protein is removed by preferably precipitation or filtration before and/or after hydrolysis is treated with a microorganism which produces β-galactosidase or with an enzyme reagent containing β-galactosidase to obtain a hydrolyzed lactose product containing no protein. Then the obtd. product is added to a food sweetener essentially comprising sucrose in such a manner that 1.5 to 20 dry pts.wt. (TGT) of the obtd. product calculated as galactose, preferably 3 to 7 TGT, is added to 100 TGT of sucrose. |
