The invention relates to carrageenan-containing compositions with improved gelling properties, syneresis <=3.0 wt. % and breaking strength improved by at least 20% compared to the carrageenan-containing starting material. Said composition contains at least 60 wt. % of carrageenan, preferably k-carrageenan, and a hydrocolloid or protein starch or mixtures thereof. The invention also relates to a method for improving the gelling properties of a carrageenan-containing composition, comprising humidifying the starting material, preferably with water, mixing it at elevated temperatures and conditions of high pressures and high shearing strains, and finely cooling the output material before comminuting it. The invention also relates to the use of the composition in nutriment and pharmaceutical formulations, preferably as texturing agent, viscosifier, gelling agent, film forming agent, Theological aid or stabilizer. The compositions have improved gelling consistency, reduced syneresis and accelerated gelation capacity and, in powder form, have excellent dispersing capacity in solutions.
