PURPOSE:To obtain a readily handleable compound with a high phosphatidylcholine (PC) content, having excellent dispersibility in water and capable of forming an aqueous dispersion having a low viscosity, by blending a concentrated lecithin containing PC with an oily dispersion and aqueous dispersion and spray drying the resultant blend. CONSTITUTION:Concentrated lecithin containing >=80wt.% phosphatidylcholine (hereinafter abbreviated to PC) is homogeneously dispersed in a fat or oil in an equal amount or less to provide an oily dispersion. A coating agent consisting of a water-soluble protein, water-soluble glucide and cellulose powder is dissolved or dispersed in water to afford an aqueous dispersion. In the process, a buffering agent, e.g. trisodium phosphate, etc., is preferably used to adjust the pH to 11-12. 50-90wt.% oily dispersion is blended and homogenized with 10-50wt.% aqueous dispersion in the presence of a thickening agent and emulsifying agent and the resultant blend is spray dried to provide the aimed substance.
