[ I claim:] [1.] A method of producing a semi-refined carrageenan comprising the steps of:(1) reacting a seaweed starting material containing carrageenan, in a substantially homogeneous alkaline mixture of a solvent in which carrageenan is substantially insoluble, and an aqueous phase comprising an alkaline substance, to obtain at least partial formation in the carrageenan of 3,6-anhydro units,(2) separating the seaweed material from the reaction mixture of step (1) and subjecting the seaweed material to at least one washing step with a solvent/water mixture, and(3) subjecting the seaweed material resulting from step (2) to shear stress.
