The present invention relates to a composition comprising Low Molecular Weight –Arabinoxylan (LMW-AX) with branched oligosaccharides, preferably at least one branched oligosaccharides is positioned at or adjacent to a reducing end of the LMW-AX backbone. The present invention also relates to the production and use thereof. The present invention further relates to acomposition comprising Low Molecular Weight –Arabinoxylan (LMW-AX) with oligosaccharides, where a fraction of the Araf units have been removed to improve the yield of oligosaccharides.
