The present invention relates generally to the production of steviol glycosides. Provided is a method for enzymatically providing a modified steviol glycoside, comprising incubating a steviol glycoside substrate in the presence of sucrose and the glucansucrase GTF180 of Lactobacillus reuteri strain 180, or a mutant thereof having the desired transglycosylation activity. Also provided are modified steviol glycosides obtainable by a method of the invention, and the use thereof as low-glycemic sweetener.
