Abstract
Abstract A puffable food composition is provided by extruding a mixture of ground animal parts and starch whereby the mixture is at least partially gelatinized during extrusion into a shape-sustaining form. The form is puffed either at the die of the extruder, or in subsequent hot oil frying, or both. With added flavoring, the puffed composition has the taste, texture and mouth feel of fried pork skins. The process accommodates a wide variety of animal parts without the necessity of substantial changes in the process parameters.

Claims Analysis
Total Claims: 34
Claim 1
Independent Claim
149 words
In a method for producing a puffable composition containing animal parts comprising providing dried animal parts, defatting the dried animal parts to a reduced fat content, passing the defatted animal parts through an extruder at sufficiently elevated temperatures and pressures to form a moldable mass, extruding the moldable means into an extruded shape-sustaining form and cutting the form into portions thereof, the improvement comprising admixing a starch with the said animal parts, prior to said extruding step, maintaining the extruder at a temperature where the starch or the starch and animal parts are at least partially gelatinized, and cutting the extruded form into portions thereof and wherein the mixture fed to the extruder has a moisture content between 10% and 35%, a fat content of less than 15% and the weight percent of said starch, based on the mixture of starch and animal parts is from 10% to 75%.
Claim 2
Dependent Claim
149 words
In a method for producing a puffable composition containing animal parts comprising providing dried animal parts, defatting the dried animal parts to a reduced fat content, passing the defatted animal parts through an extruder at sufficiently elevated temperatures and pressures to form a moldable mass, extruding the moldable means into an extruded shape-sustaining form and cutting the form into portions thereof, the improvement comprising admixing a starch with the said animal parts, prior to said extruding step, maintaining the extruder at a temperature where the starch or the starch and animal parts are at least partially gelatinized, and cutting the extruded form into portions thereof and wherein the mixture fed to the extruder has a moisture content between 10% and 35%, a fat content of less than 15% and the weight percent of said starch, based on the mixture of starch and animal parts is from 10% to 75%.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein the percent of starch is up to 65%.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein the percent of starch is up to 55%.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein the starch is one or more of a ground cereal, potato starch and corn starch, and mixtures thereof.
Claim 6
Dependent Claim
14 words
The method of claim 1 wherein the starch is pregelatized starch or modified starch.
Claim 7
Dependent Claim
24 words
The method of claim 1 wherein the temperature of the mixture in the extruder is at least 210° F. and up to 350° F.
Claim 8
Dependent Claim
15 words
The process of claim 6 wherein the temperature is between 250° F. and 330° F.
Claim 9
Dependent Claim
17 words
The process of claim 1 wherein all of the starch is admixed with the defatted animal parts.
Claim 10
Dependent Claim
17 words
The process of claim 1 wherein all of the starch is mixed with the dried animal parts.
Claim 11
Dependent Claim
17 words
The process of claim 1 wherein the extrudate which exits the extruder is at least partially puffed.
Claim 12
Dependent Claim
21 words
