The invention relates to a method for the fractionation of molasses using a chromatographic simulated moving bed system with two or more loops in which the liquid flow can be effected in a system comprising at least two chromatographic partial packing material beds. In the method of the invention, product(s) are recovered during a process comprising one or more of the following phases: a feeding phase of molasses, an eluting phase and a recycling phase. The liquid present in the partial packing material beds with their dry solids profile can be recycled in the recycling phase in one or more loops comprising one or more partial packing material beds.
