    • The present invention provides a method of modifying the swelling behavior of a dietary fibre in an aqueous medium by providing a synergistic fibre composition comprising the dietary fibre embedded within a lipid material comprising a lipid selected from a free fatty acid exhibiting a melting point in the range of from 30 to 60 °C, a glycerol- or sorbitan based fatty acid ester exhibiting a melting point in the range of from 30 to 75 °C, a plant-derived wax exhibiting a melting point in the range of from 30 to 75 °C, or a homogenous mixture of two or more of these lipids, wherein said homogenous mixture exhibits a melting point in the range of from 30 to 70 °C; wherein the swelling behavior is modified in such a way that the maximum viscosity that is achieved by mixing the synergistic fibre composition, comprising the dietary fibre(s) at an amount x_fibre, in a given volume Vx of the aqueous medium (ηmax_syn) is higher than the maximum viscosity achieved in the same volume Vx of an aqueous medium by the dietary fibre(s) alone at the same amount x_fibre (ηmax_fibre), higher than the maximum viscosity achieved in the same volume Vx of the aqueous medium by any of the other components of the synergistic fibre composition (ηmax_other) and higher than the cumulative maximum viscosity of ηmax_fibre plus ηmax_other (ηmax_∑); and optionally the swelling exhibits sigmoidal viscosity kinetics characterized by a lag time of at least 15 min, followed by a viscosity increase to at least 80 % of the maximum viscosity (ηmax_syn), that is achieved by mixing the synergistic fibre composition comprising the dietary fibre(s) at an amount x_fibre in a given volume Vx of the aqueous medium, within no more than 2 h. The present invention further provides respective synergistic fibre compositions exhibiting the modified swelling behavior of the dietary fibre comprised therein; as well as methods of using said synergistic fibre compositions.
