DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0029] The accompanying figures show a composite food product with double filling, generally designated by numeral 1, which is mainly designed for preparation of dishes of high gastronomic quality.

[0030] Particularly, the food product 1 of the invention may be one of the Italian dumplings known as ravioli, panzerotti, tortelli, cappelletti or the like and may be designed to be eaten either raw and cooked.

[0031] If the product 1 is intended for cooking, it may be namely designed to be either boiled, e.g. in water or broth or baked, cooked in a microwave oven or fried in oil.

[0032] The composite food product, as best shown in FIGS. 1A and 1B essentially comprises an envelope 2 made of pasta, which encloses therein a filling 3 made of edible food raw materials.

[0033] For example, the envelope 2 may be formed from a sheet of pasta dough composed of soft-wheat flour, durum-wheat flour, eggs and possibly a very small amount of water. The sheet may have a thickness ranging from 0.5 to 2.5 mm, and preferably of about 1 mm.

[0034] The raw materials that form the filling may be selected from the group comprising, for example, meat, fish, eggs, cheese, cold cuts, vegetables, cereals, protein- and fat-based substances, flavors and spices, possibly added with seasonings, flavors and sauces, even though these cannot be easily combined according to traditional recipes.

[0035] The pasta envelope 2 may have a predetermined size and shape, allowing it to contain the filling 3, according to the particular type of food product 1 to be obtained.

[0036] According to a peculiar characteristic of the invention, the envelope 2 consists of at least one sheet 4 of fresh pasta and the filling 3 comprises at least one first dose D.sub.1 of a first component 5 and at least one second dose D.sub.2 of a second component 6 other than the first component. Particularly, the doses are distinct D.sub.1, D.sub.2, while being both enclosed within the same envelope 2.

[0037] In one embodiment, the envelope 2 includes a third dose D.sub.3 of a third component 12. The doses are distinct D.sub.1, D.sub.2, and D.sub.3, while being all enclosed within the same envelope 2.

[0038] The choice of fresh pasta and its base components shall allow the envelope 2 to optimally wrap the outer surface of the filling 3 with high surface adhesion, for almost perfect liquid tightness, even in boiling liquids, as required for cooking with no loss of filling 3. Furthermore, this will provide food products 1 with double filling having a characteristic taste, and faithfully reproducing the traditional regional gastronomy tastes.

[0039] Namely, the envelope 2 may be made up of a lower layer 7 and an upper layer 8 of fresh pasta, which are in mutually overlapped or juxtaposed relationship and are joined together along a substantially continuous peripheral edge C having a predetermined shape, in accordance with the type of desired product.

[0040] Conveniently, once the layers 7, 8 are joined along the peripheral edge C, the envelope 2 will be preferably substantially hermetic, i.e. substantially liquid-tight or upon boiling, such that it will not break during boiling and will not lose the filling 3. The peripheral edge C may be planar.

[0041] In a first embodiment of the envelope 2, as shown in FIG. 3, the layers 7, 8 may be formed from the same sheet 4 of fresh pasta, which is folded on itself along a longitudinal line L using a special ploughshare-shaped blade, not shown and known to the skilled person.

[0042] This embodiment is particularly suitable to make products 1 such as tortelli, cappelletti, panzerotti and the like.

[0043] As an alternative to this envelope 2, as shown in FIG. 4, the layers 7, 8 may consist of two distinct and separate sheets of fresh pasta 4, 4 in mutually overlapped relationship. This embodiment is particularly suitable to make products such as ravioli and panzerotti.

[0044] In a preferred embodiment, the doses D.sub.1, D.sub.2 may be arranged in substantially concentric relationship.

[0045] Particularly, the doses D.sub.1, D.sub.2 may be laid on the lower layer 7 in concentric arrangement.

[0046] Furthermore, the doses D.sub.1, D.sub.2 may be laid on the lower layer 7 substantially at the same time, by coextrusion, using a double-tube nozzle U, as shown in FIGS. 1A and 3.

[0047] Alternatively, the doses D.sub.1, D.sub.2 may be arranged in substantially coplanar relationship.

[0048] Particularly, the doses D.sub.1, D.sub.2 may be laid on the lower layer 7 at successive times, using single-tube nozzles U, U, although in substantially superimposed and substantially concentric positions 7, 8, as shown in FIGS. 1B and 4.

[0049] Once the doses D.sub.1, D.sub.2 have been laid on the lower layer 7, a portion of the sheet 4 may be folded thereon along the line L, or a second sheet 4 may be laid thereon, to form the upper layer 8 and define a semifinished product 1.

[0050] In one embodiment, an additional third dose D.sub.3 of a third material 12 is laid in overlapping relationship over the first dose D.sub.1 and the second dose D.sub.2, which may be disposed in a substantially concentric and/or coplanar relationship.

[0051] Finally, the semifinished product 1 may be cut to size using a forming and cutting tool P, such that the layers 7, 8 will be joined along a peripheral edge C and cut thereat to form a finished product 1.

[0052] Thus, the finished product will be closed in perfectly liquid-tight fashion, at its peripheral edge C.

[0053] Preferably, the doses D.sub.1, D.sub.2 may have their respective components 5, 6 ranging from 5% to 95%, preferably from 10% to 90% by weight, based on the total weight of the filling 3.

[0054] In a further aspect, the invention relates to a method of making food products.

[0055] Particularly, the method comprises preparing an envelope 2 made of fresh pasta dough and introducing a filling 3 made of edible raw materials 5, 6 therein.

[0056] In a preferred embodiment, the method comprises a first step a) in which a lower layer of fresh pasta 7 is prepared.

[0057] In the next step b), a first filling component 5 and at least one second filling component 6, other than the first component 5, are prepared.

[0058] In the following step c), a first dose D.sub.1 of the first component 5 and a second dose D.sub.2 of the second component 6 are laid on the lower layer 7.

[0059] Conveniently, the method comprises a step d) in which an upper layer 8 of fresh pasta is prepared and laid over the lower layer 7 to cover the doses D.sub.1, D.sub.2.

[0060] In the next step e), the lower layer 7 and the upper layer 8 are joined along a substantially continuous peripheral edge C, whose shape matches the shape of the finished product 1 to form a filled semifinished product 1.

[0061] In step f), the filled semifinished product 1 is cut along the edge C to form the finished food product 1.

[0062] Particularly, the semifinished product 1 may be cut proximate to the peripheral edge C to obtain a shape of the finished product 1 that is slightly different from that of the edge itself.

[0063] Conveniently, in step c), the doses are laid on the lower layer 7 at the same time, as shown in FIG. 3, or at successive times, as shown in FIG. 4.

[0064] Conveniently, the first component 5 and the second component 6 may be heated to a predetermined temperature T.sub.r substantially at the same time as they are laid on the lower layer 7.

[0065] The first dose D.sub.1 and the second dose D.sub.2, as best shown in FIG. 3, may be substantially concentric and laid by simultaneous coextrusion of the first component 5 and the second component 6.

[0066] Alternatively, the first dose and the second dose, as best shown in FIG. 3, may be substantially concentric and laid by coextruding one of the first component 5 and second component 6 later than the other of the second component 6 or the first component 5.

[0067] Conveniently, as best shown in FIG. 3, the lower layer 7 and the upper layer 8 may be obtained by folding a single sheet 4 of fresh pasta on itself.

[0068] Alternatively, as best shown in FIG. 4, the lower layer 7 and the upper layer 8 may be obtained from two distinct sheets 4, 4 of fresh pasta.

[0069] The two sheets 4, 4 may be in at least partially overlapped relationship. Particularly, the filling 3 may be laid on a sheet 4 of fresh pasta, whereas the other sheet 4 of fresh pasta may be laid at least partially over the first sheet 4 and totally over the filling 3.

[0070] Particularly, single-sheet food products 1 are made by forming the lower layer 7 and the upper layer 8 by folding a single sheet of fresh pasta 4 on itself.

[0071] Alternatively, double-sheet food products 1 are made by forming the lower layer 7 and the upper layer 8 by laying two distinct sheets of fresh pasta 4, 4 in overlapped relationship.

[0072] In a continuous process, the lower layer 8 and the upper layer 9 are both in the form of strips 10, 11, as shown in FIGS. 3 and 4, and are fed in a substantially longitudinal direction L. Each of the strips 10, 11 is fed in the direction L by a moving conveyor surface, such as a closed-loop belt conveyor N.

[0073] Conveniently, as shown in FIG. 3, the doses D.sub.1, D.sub.2 may be laid by simultaneous coextrusion of the first component 5 and the second component 6 on one of the strips 10 in predetermined positions along the longitudinal extent thereof, and may be later covered by the other strip 11.

[0074] Furthermore, as shown in FIG. 4, a dose D.sub.1 may be laid on one of the strips 10 in a predetermined position and the other dose D.sub.2 is laid above the dose D.sub.1 in a substantially concentric position.

[0075] The latter dose may be laid later than the dose D.sub.1 laid on the strip 10.

[0076] The overlapped doses D.sub.1, D.sub.2, as shown in FIG. 4, may be later covered by the other strip 11.

[0077] The above disclosure clearly shows that the composite food product with double filling and the method of the invention fulfill the intended objects and particularly meet the requirement of providing a filled food product comprising at least one sheet of fresh pasta and having a high organoleptic value.

[0078] The filled food product and method of the invention are susceptible to a number of changes or variants, within the inventive concept disclosed in the annexed claims.

[0079] All the details thereof may be replaced by other technically equivalent parts, and the materials may vary depending on different needs, without departure from the scope of the invention.

[0080] While the filled food product and method of the invention have been described with particular reference to the accompanying figures, the numerals referred to in the disclosure and claims are only used for the sake of a better intelligibility of the invention and shall not be intended to limit the claimed scope in any manner.
