    摘要: The present invention relates to a process for preparing a formulation comprising an alkali metal salt selected from the group consisting of alkali metal bicarbonate salts, alkali metal carbonate salts, alkali metal sesquicarbonate salts and combinations thereof, wherein said process comprises: (a) dissolving a functionalizing agent in a solvent; (b) mixing the alkali metal salt with the solution comprising the functionalizing agent that a paste-like composition is formed; (c) extruding the paste-like composition to obtain filaments or granules; (d) at least partially removing the solvent from the filaments or granules. The invention furthermore relates to filaments and granules obtainable from said process and to the use of these filaments or granules in various applications such as in plastic foaming or in food leavening compositions.
