Provided are: a powder emulsifying agent composition which has improved dispersibility and is capable of providing food with excellent texture and a production method by which this powder emulsifying agent composition can be obtained easily. An emulsifying agent composition that contains (A) a saccharide, (B) a glycerol fatty acid monoester and (C) a lecithin, in which the phospholipid content is 90% by mass or more and the total content of phosphatidic acid and a hydrogenated product thereof is 5-30% by mass, is used. This emulsifying agent composition is obtained by spray drying an aqueous dispersion that contains the components (A)-(C).
