The invention relates to a process for the recovery of betaine from a molasses, comprising: - a conversion step, in which the molasses is subjected to the action of an enzyme having endo-inulinase activity and/or fructosyltransferase activity, to form a fructan-containing molasses (fructan-molasses)； - a separation step, in which the fructan-molasses is subjected to a chromatographic separation, thereby obtaining a betaine-containing fraction.
