Abstract
Abstract A method and apparatus for preparing food products wherein an extrudable slurry of the food product and a gel forming material which is settable upon exposure to a setting solution and is capable of forming a skin, is extruded into an elemental shape, such as a torroid, while washing the surfaces of the elemental shape with the setting solution to form a skin onto the shape. Extrusion is continued to expand the elemental shape into a final extruded food product, with the skin serving to envelope and contain the initial slurry during further extrusion and until such time as the product is completed, as by further processing which may include coating and finally stabilizing the slurry as by cooking, baking, frying, freezing or the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
21 words
The method according to claim 1 including the further step of exposing the final extruded food product to said gelation agent.
Claim 2
Dependent Claim
34 words
The method according to claim 2 including the further step of coating the extruded food product with an edible coating with said skin providing a substantially continuous surface for application of said edible coating.
Claim 3
Dependent Claim
19 words
The method according to claim 2 including the further step of cooking the enveloped extrusion to stabilize said slurry.
Claim 4
Dependent Claim
15 words
The method according to claim 4 wherein the cooking step comprises baking the enveloped extrusion.
Claim 5
Dependent Claim
15 words
The method according to claim 4 wherein the cooking step comprises frying the enveloped extrusion.
Claim 6
Dependent Claim
24 words
The method according to claim 2 wherein said gel-forming material is in alginate and said gelation agent is a source of alkaline earth ions.
Claim 7
Independent Claim
120 words
A method of preparing onion rings from onion particles comprising the steps of forming an extrudable slurry containing onion particles and an ungelled gel forming material that normally forms a gel upon exposure to a gelation agent, extruding an elemental toroidal shape from said slurry while washing only the surfaces thereof with a gelation agent to form a ring of said slurry contained within a surface skin, the gel-forming material in said slurry contained within said skin remaining ungelled, cutting off the completed ring from the remainder of said slurry, placing said ring in a bath of said gelation agent to build up said surface skin, removing said skin from said bath and cooking said ring to stabilize said slurry.
Claim 8
Dependent Claim
52 words
The method according to claim 8 wherein said extrusion occurs with said elemental torroidal shape in a horizontal attitude and subject to the forces of gravity and said washing is from above and assists in releasing said completed ring from the remainder of said slurry when said completed ring is cut off.
Claim 9
Dependent Claim
14 words
The method according to claim 9 wherein said completed ring falls into said bath.
Claim 10
Dependent Claim
22 words
The method according to claim 8 wherein said further processing includes the step of applying an edible coating to the enveloped extrusion.
Claim 11
Independent Claim
126 words
The method of preparing a shaped and extruded food product comprising the step of forming an extrudable slurry containing food particles and an ungelled gel-forming material that normally forms a gel upon exposure to a gelation agent, extruding said slurry into an elemental shape while washing the surface thereof with a batter-wash containing a gelation agent capable of forming an outer skin on said shape which continuously grows incident to continued extrusion and retains said shape throughout extrusion, the gel-forming material retained within said outer skin remaining ungelled, immersing the final extrusion in a batter-bath containing said gelation agent to build up said outer skin and complete a substantially continuous envelope containing said slurry for further processing and cooking the enveloped extrusion to stabilize said slurry.
Claim 12
Dependent Claim
22 words
The method according to claim 12 wherein said further processing includes the step of applying an edible coating to the enveloped extrusion.
Claim 13
Dependent Claim
22 words
The method according to claim 13 wherein said slurry contains a cookable and edible binder and said food particles are comminuted onions.
Claim 14
Dependent Claim
15 words
The method according to claim 14 wherein the cooking step comprises frying the enveloped extrusion.
