at low vanillyl alcohol concentrations up to 50 mM, or if the reaction is prolonged to 3 h at higher concentrations of vanillyl alcohol, additional transglucosylation product vanillyl alcohol alpha-isomaltoside is detected. The transglucosidation takes place at the C6 hydroxyl group of vanillyl alcohol alpha-D-glucoside
