PURPOSE: To obtain a processed food of fats and oils having improved flavor and shelf stability free from rough feeling to the tongue, by grinding a hot blend of fats and oils, a dried food ingredient, and an emulsifying agent, processing the blend into ultrafine particles, homogenizing them, cooling and solidifying them to give a composition, blending the composition with margarine during its preparation.

CONSTITUTION: Fats and oils are melted, blended with a dried food ingredient (e.g., processed food of dairy farming, et.) and an emulsifying agent (e.g., monoglyceride, etc.), and, if necessary, starch, a saccharide (e.g., glucose, etc.), and powdered milk by a kneader, etc. Then, the blend is ground by rollers, pulverized and/or polished by an ultrafine pulverizer and/or a polisher, processed into ultrafine particles, homogenized, cooled, and solidified to give a composition. The composition is continuously added to margarine during its preparation, and blended by a static blender, to give the desired processed food of fats and oils.
