Abstract
Abstract Disclosed is a method for adding fat to an expanded, farinaceous food product. The fat is injected into a food extruder in a manner which permits it to become intimately mixed with the food but does not interfere with product cooking or expansion. The foods may be for human or animal consumption. In a preferred embodiment, a high caloric density puppy food is prepared.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
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.
Claim 2
Dependent Claim
125 words

Claim 3
Dependent Claim
34 words
An improved process according to claim 1 wherein the fat is injected in an amount effective to add at least 4% fat to the final product based on the weight of the dry product.
Claim 4
Dependent Claim
35 words
An improved process according to claim 1 wherein the fat is heated to a temperature of at least 175° C. prior to injection to produce a deep fat fried flavor and appearance in the food.
Claim 5
Dependent Claim
19 words
An improved process according to claim 1 wherein the food product is a ready-to-eat breakfast food for human consumption.
Claim 6
Dependent Claim
47 words
An improved process according to claim 1 wherein the dog food product is especially formulated to meet the nutritional requirements of puppies and the fat is injected in an amount effective to add from 4 to 10% fat based on the dry weight of the final product.
Claim 7
Dependent Claim
32 words
A process according to claim 5 wherein the fat is tallow and the process includes the further step of heating the tallow to a temperature effective to liquify it prior to injection.
Claim 8
Dependent Claim
14 words
A process according to claim 1 wherein the food is a nutritionally-balanced cat food.
