In a process for preparing an expanded, farinaceous food by moistening, heating and mechanically working a farinaceous mixture, comprising 35-70% farinaceous ingredients and 20-50% protein ingredients sufficiently to raise the temperature to substantially above 100°C., raise the pressure in excess of ambient, and to gelatinize starch granules; and thereafter extruding the farinaceous mixture containing gelatinized starch through a die into a zone maintained at a pressure sufficiently below that of the heated and worked mixture to cause expansion and partial drying of the mixture, the improvement which comprises: injecting at least 2% fat into the farinaceous mixture at a point after substantial gelatinization of the starch but prior to extrusion through the die which permits the fat to become intimately mixed with the food.
