ABSTRACT:
A process for preparing a fructoside, especially a fructosyl disaccharide, comprises reacting a fructosyl saccharide such as sucrose or raffinose with an alcohol or aldose in the presence of a fructosyl-transferase, especially one derived from B. subtilis NCIB 11811, 11872 or 11873. In particular, aldose is a compound of the formula ##STR1## in which A represents a hydrogen atom or the group CH.sub.2 X, where X represents a hydrogen atom or an alkoxy group, and the fructosyl disaccharide so formed is halogenated to provide a halosucrose or halogalactosucrose sweetener.
