DETAILED DESCRIPTION

Referring to the FIGURES generally, various embodiments disclosed herein relate to food products (e.g., stuffed, extruded, co-extruded, and/or tri-extruded food products, etc.) and systems and methods for making such food products. As used herein, the term “food product” includes, but is not limited to, whole, ground, blended, and/or emulsified protein based products (e.g., meat, non-meat such as soy, etc.) in a variety of forms such as links or rings (e.g., sausage, bratwurst, hot dogs, wieners, lunchmeat, etc.) generally having a collagen, cellulose, or other casing or outer layer, whether edible or stripped/discarded. The term “extruded food product” includes food products with a single or multiple extruded components so as to include food products made by simultaneously extruding (e.g., co-extruding, tri-extruding, etc.) more than one food component As used herein, “about” will be understood by persons of ordinary skill in the art and will vary to some extent based upon the context in which it is used. If there are uses which are not clear to persons of ordinary skill in the art, given the context in which it is used, “about” will mean up to plus or minus 25% of the particular term.

Some embodiments herein relate to an extruded food product having an inner meat component, and a relatively thin middle component comprising a heat settable and flowable carrier (e.g., a meat emulsion, etc.) that carries one or more inclusions, and an outer layer (e.g., a collagen layer) forming a casing that is applied over the thin middle component The food product may provide the visual appearance of a hand-rubbed, or rolled-on topical spice or additive that is visible through the outer layer.

Systems and methods utilized to produce such food products include extrusion systems having inner and outer tubes. Food components are extruded through the inner and outer tubes (e.g., through the inner tube and through an annular space defined between the inner and outer tubes). In some embodiments, the size of the annular space, or gap, defined by the inner and outer tubes is substantially larger than that used in traditional coextrusion processes, which use a substantially smaller gap and therefore are more limited in terms of particulate size of inclusions. Upon exiting the tubes, the inner component “mushrooms,” or expands in diameter, while the thin middle component thins, or reduces in thickness. Due to the larger size of the annular space between the inner and outer tubes, the middle component may include inclusions that are of a size larger than that which can be accommodated with traditional extrusion systems, and yet the food product may still have a relatively thin middle component over the inner, or main extruded component An outer layer (e.g., collagen gel, alginate gel, combinations thereof) may be extruded or otherwise provided over the middle component (e.g., as a pre-formed casing such as a natural, cellulose, collagen, or other casing into which the inner and middle components may be “stuffed”). In some embodiments, the inner and/or outer tubes may be coupled to a nozzle portion, and the nozzle portion may have dimensions similar or different from the inner and/or outer tubes. It should be noted, however, that other methods and/or apparatuses (instead of a nozzle portion) may be used to effectuate extrusion from or via the inner and/or outer tubes.

Referring now to FIGS. 1A-1C, a food product 10 is shown according to an exemplary embodiment. As shown in FIG. 1A, food product 10 includes a first, or inner layer or component 12 (e.g., a base layer, primary layer, etc.), a second, or middle layer or component 14 (e.g., an inclusion or emulsion layer, a combination carrier and inclusion layer, a layer including one or more of a flavoring, sauce, spice, coloring, and textural additive, etc.), and a third, or outer layer or component 16 (e.g., a collagen layer or gel, an alginate layer or gel, a collagen/alginate hybrid layer or gel, a pre-formed outer casing, etc.). Food product 10 may include any of a variety of food products, including sausages, bratwurst, hot dogs, breakfast sausage, lunchmeat, etc. For example, food product 10 may be a cooked or raw peppercorn beef rope (FIG. 8A), peppercorn beef hot dog (FIG. 8B), buffalo chicken rope (FIG. 8C), etc.

According to an exemplary embodiment first component 12 is a protein-based material such as meat soy, etc., and may be provided in a variety of forms (e.g., chunk, ground, emulsified, sliced, comitrolled, pulled, dough, whole muscle, combinations thereof, etc.). First component 12 may include inclusions such as food particles (e.g., cheese, seasonings, spices, grains, etc.), colorings, liquid smoke or other flavorings or additives, etc. In some embodiments, first component 12 is a meat blend including more than one type of meat, or alternatively, meats having a different formula, such as, e.g., meats having a different texture, color, taste, salt content, seasoning/spice content, etc.

Referring now to FIGS. 1B and 1C, second component 14 includes a carrier 18 and inclusions 20 according to an exemplary embodiment. Carrier 18 may be a protein-based material such as meat, soy, collagen, etc., and may be provided in dough, liquid, and/or ground form, or any of the forms discussed with respect to first component 12. Inclusions 20 may include topicals, particulates, and/or additives such as food particles (e.g., sundried tomatoes, flaked basil, pepper, spices, etc.), colorings, flavorings (e.g., salt, seasoning, liquid smoke etc.), combinations thereof, and the like. Second component 14 may be the same or a different type of food product from first component 12 (e.g., to provide a different texture, flavor, color, etc., from first component 12). In one embodiment, second component 14 includes the same type of meat blend as first component 12, but includes additional inclusions such as spices, flavorings, particulates, etc. As such, the first and second components may be used in combination to provide a meat product with a thin outer layer of inclusions (e.g., meat, spices, etc.) that provide the visual appearance of a rubbed-in topical spice, flavoring, etc. It should be noted that in accordance with certain embodiments, the second component need not necessarily include relatively larger-sized particulate inclusions, instead being particulate-less, or having small inclusions, such as spices, or coloring, for example, while the first component may, as previously described, have larger-sized inclusions, while still resulting in a hand-rubbed, or rubbed-on appearance/texture. Carrier 18 may be a ground, emulsified, pulled, or other meat (e.g., ground beef, poultry, pork, lamb, goat, or combinations thereof etc.). According to an exemplary embodiment, carrier 18 is a flowable, heat-settable layer such as a meat emulsion or fluid layer (e.g., a fluid meat carrier, emulsion, blend, etc.) and is configured to provide a carrier material for inclusions 20. Second component 14 may be of a different consistency (e.g., grind, texture, etc.) than first component 12. For example, first component 12 may be a course ground (e.g., chunks, pieces, etc.) and second component 14 may be emulsified or finely ground.

Outer layer 16 provides a casing for food product 10, and may be a collagen layer or gel, an alginate layer or gel, a collagen/alginate hybrid layer or gel, a preformed casing such as a natural or other preformed casing, or similar material. In one embodiment, outer layer 16 is a settable gel or coating configured to set upon the application of heat, a chemical bath, liquid smoke, and/or combinations thereof, etc. In some embodiments, the outer layer includes inclusions such as colorings, spices, particulates, or combinations thereof, etc. Outer layer 16 is configured to be transparent or translucent such that inclusions 20 in second component 14 are visible through the outer layer. Outer layer 16 may also permit inclusions 20 contained in carrier 18 of second component 14 to “bulge” under the outer layer, providing an outer layer or casing with a surface contour conforming to the inclusions below the outer layer (see FIGS. 1B-1C). Furthermore, outer layer 16 may provide a pronounced “bite” for users (e.g., a “snap bite,” etc.), which may be desirable with certain food products.

Referring now to FIGS. 3A-6C, a system and method for making a food product such as food product 10 is shown in greater detail. According to an exemplary embodiment, an extrusion system 40 for making food products includes a first inlet 42, a second inlet 44, a head portion 46, and an outlet, or exit 48 (e.g., a nozzle, etc.) (see FIG. 3A). An inner tube 50 and an outer tube 52 extend from first and second inlets 42, 44 to exit 48 and define an annular space 58 therebetween (see FIGS. 3B, 4A-4D, 5A-5C, and 6A).

First inlet 42 is configured to receive a first food component such as first component 12. Tube 50 guides the first food component toward exit 48. Second inlet 44 is configured to receive a second food component such as second component 14. Annular space 58 guides the second component toward exit 48. Adjacent exit 48, head portion 46 (e.g., a collagen applicator such as a collagen head, etc.) is configured to apply (e.g., extrude, etc.) a collagen gel or other suitable material to the surface of the second food component as it exits outlet 48 (see FIGS. 3A, 6A and 6B). According to an exemplary embodiment, head portion 46 applies or deposits collagen to the surface of second component 14 in a linear and/or radial manner, e.g., in a direction angled to or generally perpendicular to the direction of flow of first and second components 12, 14 through the extrusion system. Upon exiting from outlet 48, the food product may be directed to a conveyor belt or other system for further processing, conditioning, packaging, etc.

First and second inlets 42, 44 and head 46 may include or be coupled to one or more hoppers, pumps, grinders, and/or similar mechanisms configured to receive food product and/or collagen or other materials and force or extrude the materials through inner tube 50 and annular space 58. The flow rate, i.e. the rate at which the first and second components are extruded may be varied depending on the desired characteristics of the final product For example, by increasing/decreasing the flow rates at which the first/second food components are extruded, the relative proportions of the first and second food components in the final food product may be varied.

As shown in FIG. 3B, inner tube 50 has a diameter 54, and annular space 58 has a “thickness” 56 (e.g., the radial distance defined between the inner and outer tubes). According to one embodiment, diameter 54 is approximately 16 mm and thickness 56 is approximately 5 mm (see FIG. 3C). According to various other embodiments, diameter 54 and thickness 56 may take other dimensions. In various alternative embodiments, diameter 54 and thickness 56 and/or flow rates may be varied to provide food products with particular relative portions/characteristics of first and second food products.

The diameters of inner tube 50 and outer tube 52 may be proportionately related to provide a desired final size of first component 12 and a desired thickness of second component 14. In one embodiment, inner tube 50 has a diameter that is about 50% of the diameter of outer tube 52. In other embodiments, inner tube 50 has a diameter that is between about 45-55%, between about 40-60%, or between about 35 to 65% of the inner diameter of outer tube 52. The ratio of the diameters of the inner outer tubes may further differ according to various other exemplary embodiments.

According to an exemplary embodiment, outlet 48 is provided by way of a separate nozzle such as nozzle 60 shown in FIGS. 6C and 7A. Nozzle 60 includes an inner tube 62 and an outer tube 65 (which may be embodiments of inner tube 50 and outer tube 52, respectively) that define an annular space 64. As shown in FIG. 7A, the nozzle may have an annular space generally corresponding in size to those provided by inner and outer tubes 62, 65, with the collagen head 46 provided to the outside of the inner and outer tubes 62, 65, of the nozzle 60. Thus, any dimensions or variations in dimensions relating to inner and outer tubes 62, 65, may be equally applicable to the configuration of the nozzle. According to various alternative embodiments, inner tube 62 and annular space 64 may be sized differently from those provided by inner and outer tubes 50, 52. Referring to FIGS. 7B and 7C, in some embodiments, inner tube 62 (FIG. 7B) or inner tube 62 and outer tube 65 (FIG. 7C) of nozzle 60 may include a restriction portion 66, 68, where the inner diameter of inner tube 62 and/or outer tube 65 may be decreased. According to yet further embodiments, the extrusion system may be configured such that a separate nozzle is not utilized, or the nozzle is an integrated portion of the inner and/or outer tubes (e.g., part of a unitary tube structure). In other embodiments, a separate nozzle may be utilized with only one of the inner and outer tubes. The inner and outer tubes may be formed with any of the dimensional features of the separate nozzles discussed herein. As such, according to various embodiments, food product may exit the extrusion system via the inner and outer tubes, in conjunction with a nozzle or alternative extrusion mechanism, or without the use of a nozzle, where the exit aspect of the system can be defined by the inner and outer tubes themselves.

According to an exemplary embodiment, first and second components 12, 14 are extruded at rates such that, upon initially exiting outlet (e.g., at to shown in FIGS. 2A-2B), first component 12 has an initial diameter 22 and second component 14 has a thickness 26. After exiting the extrusion system, the relative sizes of diameter 22 and thickness 26 change over time upon exiting from the extrusion system/nozzle. In some embodiments, inner and outer tubes 50, 52 are sized such that upon exiting outlet 48, first component 12 substantially increases in diameter, and second component 14 substantially decreases in thickness. For example, upon exiting inner tube 50, first product 12 expands (e.g., mushrooms, etc.) from initial diameter 22 (see, e.g., FIG. 2B) to a final diameter 24 (see, e.g., FIG. 1A) after a certain period of time (e.g., at tf shown in FIG. 2A). Upon second component 14 exiting annular space 58, the thickness of second component 14 decreases from initial thickness 26 (see, e.g., FIG. 2B) to a final thickness 28 (see, e.g., FIG. 1A) to form a thin layer or covering over first component 12.

According to an exemplary embodiment, the diameter of first food product 12 can increase anywhere from, e.g., 20% to 60% from initial diameter 22 to final diameter 24, and the thickness of second component 14 can decrease by anywhere from, e.g., 40% to 60% from initial thickness 26 to final thickness 28. In still further embodiments, the thickness of second component 14 can decrease by at least about 67% (by approximately two-thirds of the original thickness) from initial thickness 26 to final thickness 28. For example, in one embodiment, the diameter of first component 12 increases from about 16 mm to over 25 mm, and the thickness of second component 14 decreases from about 5 mm to about 2 mm. In another embodiment, the diameter of first component 12 increases from about 16 mm to about 30 mm, and the thickness of second component 14 decreases from about 9 mm to about 3 mm. According to various other embodiments, the diameter of first food component 12 and the thickness of second component 14 may increase/decrease by other amounts to provide food products of varying relative proportions.

According to an exemplary embodiment additives 20 carried by carrier 18 of second component 14 are sized such that, upon the thickness of second component 14 decreasing upon exiting annular space 58, at least some of inclusions 20 may have a diameter (or other dimension such as width, in the case of non-circular inclusions) that exceeds the final thickness of carrier 18. As such, the inclusions may appear to “poke out” from the food product Extruding food components in this matter enables the extrusion of food components such as second food component 14 having inclusions of such a size that would typically not be extrudable due to the size of the inclusions exceeding the size of the annular extrusion space.

Referring now to FIG. 9, a method of making an extruded food product is shown according to an exemplary embodiment. First, a first food component is provided to a first hopper (step 72). The first food component may be a meat blend and/or similar to first food component 12. Next, a second food component is provided to a second hopper (step 74). The second food component may be a meat carrier with inclusions such as inclusions 20. An outer layer material such as a collagen material is then provided to a third hopper (step 76). The first and second food components are co-extruded (step 78), for example, using a system such as system 40. The outer layer material is then applied to the surface of the second food component to form a casing for the food product (step 80). The food product may subsequently undergo additional processing, conditioning, etc. According to various alternative embodiments, additional steps may be included at various points during the manufacturing process.

As a first example, a food product such as a pepper encrusted beef link is produced using the systems and methods herein. A first, inner component includes a meat blend (e.g., beef) ground to about 3.9 mm and may include inclusions such as cheese, seasonings, etc. (typically smaller than 1 cm). A second, middle component is coextruded with the first component, and includes a carrier of ground meat (ground through a 3.2 mm plate) and inclusions (e.g., 50% black pepper and 50% red bell pepper). The black pepper may have particle sizes of between 0.8 and 1.7 mm, and the bell pepper may have particle sizes between 0.4 and 2.8 mm. A collagen layer is applied to the outside of the second component.

During the extrusion process, the first component has a flow rate of 5600 lbs/hr, the second component has a flow rate of 2400 lbs/hr, and the collagen layer has a flow rate of 400 lbs/hr. The inner tube has an inner diameter of 15.9 mm and a wall thickness of 0.9 mm, and the outer tube has an inner diameter of 27 mm and a wall thickness of 1.45 mm (although as can be appreciated, the wall thickness of the outer tube need not have an effect on flow rate/annular size). The collagen head has an inner diameter of 28.5 mm. The final food product has an outside diameter of 27 mm, with the thickness of the collagen layer being negligible. Thus, the outer diameter of the second component is approximately 27 mm, the outer diameter of the first component is 22.6 mm, and the thickness of the second component is 2.2 mm. The weight of the final food product is 70% first food component, 30% second food component, with the weight of the collagen layer being negligible.

In a second example, a food product such as a chicken sausage rope flavored with sundried tomato and basil is produced using the systems and methods described herein. A first, inner component includes a meat (e.g., chicken) blend ground to about 3.9 mm and may include inclusions such as cheese, seasonings, etc. (typically smaller than 1 cm). A second, middle component is coextruded with the first component, and includes a carrier of ground meat (ground to 3.2 mm) and inclusions (e.g., 60% sundried tomato particles and 40% flaked basil). The sundried tomato may have particle sizes of between 0.4 and 2.8 mm). A collagen layer is applied to the outside of the second component.

During the extrusion process, the first component has a flow rate of 5600 lbs/hr, the second component has a flow rate of 2400 lbs/hr, and the collagen layer has a flow rate of 400 lbs/hr. The inner tube has an inner diameter of 15.9 mm and a wall thickness of 0.9 mm, and the outer tube has an inner diameter of 36 mm and a wall thickness of 1.45 mm. The collagen head has an inner diameter of 37.5 mm. The final food product has an outside diameter of 36 mm, with the thickness of the collagen layer being negligible. Thus, the outer diameter of the second component is approximately 36 mm, the outer diameter of the first component is 30 mm, and the thickness of the second component is 3 mm. The weight of the final food product is 70% first food component, 30% second food component, with the weight of the collagen layer being negligible.

These examples show a product with a large particulate or inclusion carried in a thin layer of meat, which would not have been possible using the known traditional coextrusion processes and equipment

It should be noted that while the various embodiments disclosed herein generally relate to a food product with first and second components extruded with an outer layer, many variations may be made within the scope of the present disclosure. For example, additional components may be extruded within the outer layer (e.g., collagen/casing layer) to surround the second component, for example. Further, while the first and second components have generally been described as being meat-based, other food types may be used, such as soy, rice, corn masa, other grains, dough products, blends thereof, etc. Further yet, while in some embodiments the final food product includes a relatively thicker primary food product surrounded by a relatively thinner middle layer, in other embodiments, the flow rate of the extrusion system may be controlled to change the relative proportions of the inner and middle food products (e.g., by increasing the extrusion flow rate of the middle component and decreasing the extrusion flow rate of the inner component, the middle component may “mushroom” upon exiting the extrusion system and provide a relatively thicker layer than shown, for example, in FIGS. 1A-1C, and 2A-2B). This can allow for, e.g., the inclusion of larger particulates or other additives within a relatively small inner layer.

The system and methods disclosed herein may provide benefits over more traditional systems and methods. For example, the systems and methods provide a food product with a thin, outer layer having inclusions without the need for hand rubbing spices, etc. onto the food product and/or rolling the food product within spices, etc. The methods disclosed herein may thus provide more efficient and safe methods, with reduced labor, mess, and/or waste as compared to more conventional techniques, where sausages may be cooked in a package, stripped from the package, rubbed in a topical seasoning, etc., repackaged, and pasteurized or subjected to other further processing. Further, the extruded food product may provide sausage links or similar food products with a pronounced “bite” while maintaining the topical seasonings, etc. visible and near the surface.

It is important to note that the construction and arrangement of the elements of the food products and/or methods as shown in the exemplary embodiments are illustrative only. Although a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in the various embodiments. Accordingly, all such modifications are intended to be included within the scope of the present disclosure as defined in the appended claims. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes, and/or omissions may be made in the design, operating conditions, and arrangement of the exemplary embodiments without departing from the spirit of the present disclosure.
