Description

Summary of Invention

[0012] According to one aspect of the invention, a pasta product having a pasta body with a pocket is provided. The pocket contains a filling having a sauce-like consistency when in a re-hydrated state. According to another aspect of the invention, a pasta with filling can be provided as a dehydrated product which can be packaged, shipped, and stored, in the same cost and convenience effective manners as conventional dried pasta alone. According to another aspect of the invention, a shelf-stable pasta product and its filling have a moisture content that is typical of conventional dried pasta. A filling of the present invention is dehydratable to a moisture content that allows shelf stability while being rehydratable to an acceptable sauce-like consistency and texture. Thus, a dehydrated pasta product of the present invention does not require sterilization through pasteurization or other processing. Upon cooking in water, sauce re-hydrates along with the pasta at acceptably similar rates.

[0013] It is contemplated that certain fillings according to the present invention may comprise any type of filling that, when dehydrated to the levels of a normal pasta, is not supportive of significant microorganism growth. It is also contemplated that suitable fillings will not exhibit degradation of texture after rehydration. Exemplary sauce-like fillings of the present invention include one or more pretreated carbohydrates, such as bread crumbs, which permits the carbohydrate to undergo primarily only rehydration upon subsequent exposure to water and/or heat, thereby ensuring a sauce-like texture of the filling while allowing the filling to be shelf stabile when dehydrated to a moisture content that is within an acceptable range for conventional dried pasta. The pretreatment of the carbohydrate may include adding water, cooking, and/or disintegration or pulverizing a solid carbohydrate.

Detailed Description

[0014] While the present invention will be described fully hereinafter with reference to the accompanying drawings, in which a particular embodiment or embodiments are disclosed, it is to be understood at the outset that persons skilled in the art may modify the specific embodiments herein described while still achieving the desired result of this invention. Accordingly, the description which follows is to be understood as a disclosure of exemplary embodiments directed to persons skilled in the appropriate art and not as limitations of the present invention.

[0015] The pasta product of the present invention is made by initially preparing a raw pasta dough. This may be done by preparing a mix comprising a ground cereal grain product and water. It is preferable, for example, to use flour and/or semolina obtained by grinding grains, such as hard wheat, soft wheat, rice, corn, or the like. Additives, such as fresh, frozen or dehydrated eggs, salt, spices, seasoning, emulsifiers and/or natural coloring matter, such as tomato or spinach, may be added to the ground product. The mixture may be kneaded to give it a pasty homogeneous texture.

[0016] A parent sheet of pasta may then be formed, for example by extrusion and/or rolling. This may be done in particular by forming a strand of pasta by extrusion and then rolling the strand between several successive pairs of rollers until a parent sheet has a desired thickness. This parent sheet may then be cut into leaves of predetermined shape for preparing the pasta envelopes mentioned. For example, the parent sheet may be cut into rectangular leaves which are then folded to form pasta envelopes in the shape of squares. The parent sheet may also be cut up into circular leaves which are then folded to form pasta envelopes in the shape of crescents. However, any preform shape may be cut from the parent sheet in order to facilitate the formation of the desired finished pasta shape. A particularly preferred pasta is an egg-based pasta which is mixed, kneaded, sheeted, cut and formed to either a classic tortellini or mezzaluna shape.

[0017] A rehydratable filling according to the invention has been developed to provide the benefits of the invention described above and to provide a pizza sauce flavor and texture. The filling includes: Ricotta and Parmesan cheeses from cow"s milk, which include cheese culture, salt, and enzymes; Romano cheese from sheep"s milk, including cheese cultures, salt, and enzymes; tomatopowder;breadcrumbs from wheat flour with salt; margarine from soybean oil including salt; ascorbic acid and citric acid; and, pizza flavor from chili powder, oregano, onion, pepper, paprika, garlic, nutmeg, sage, and basil.

[0018] The filling is preferably dehydrated and pelletized. One or more pellets (as desired) are placed on a pasta leaf by a depositor or other placing mechanism. However, the filling may also be deposited in a liquid, semi-liquid or paste-like form and then dehydrated along with the pasta leaf at a later step. The pasta is then formed around the filling, shape-formed (e.g. to a tortellini or mezzaluna shape) and sealed, thereby creating a pasta shape having a pocket containing the filling. The pasta may be formed by folding, molding, or other forming techniques. Some pasta products may also be crimped in order to seal the filling within the pasta shape. The filled pasta product is then dried to a moisture content of about 10-12% moisture by weight and a water activity of < 0.65, preferably around 0.50. This enables stability and commercial sterility for handling and storage while permitting proper rehydration.

[0019] According to the invention, the pizza-flavored sauce is comprised of prominent constituents which permit the overall filling to behave more like pasta in terms of microorganism activity at the dried moisture content than would conventional fillings such as those which have prominent meat and/or cheese constituents. Hence, the filled pasta can have significant shelf life at the dried moisture contents disclosed herein. In a preferred embodiment, these prominent constituents are bread crumbs and tomato powder which total 38%-41.5% by weight of the total weight of the sauce. These constituents behave more akin to the starches constituting the pasta than will the protein, amino acid, and enzyme-rich meat and cheese filings conventionally used as fillings. So too, these constituents behave more like the pasta starches in a rehydration process than will fillings having significant amounts of meat or cheeses.

[0020] The use of bread crumbs is exemplary on this point because, like the pasta itself, it constitutes a pre-cooked cereal grain starch. Being precooked, the starches in the bread will merely rehydrate upon cooking by the consumer. This prevents the filling from lumping into a cooked semi-solid. The bread is also crumbed to physically dissociate the cooked starch mass to further avoid a lumping of the filling. In the meantime, the crumbs add wetness to the sauce upon rehydration while adding body to the sauce in their swelled form.

[0021] Hence, it is contemplated that sauces/fillings according to the invention may be provided by addition of one or more pre-treated starches, such as bread crumbs, as a significant constituent which upon subsequent cooking by the consumer, will primarily undergo only rehydration and will assist the filling to be shelf-stable when dehydrated to a moisture content that is in an acceptable range for conventional dried pasta.

[0022] Likewise, the tomato powder is lacking the animal protein mass associated with conventional meat and cheese fillings while at the same time providing constituents very amenable to rehydration, such as sugars, salts, and starches. These constituents are important because they help suppress the water activity level.

[0023] The cheeses added to the pizza-flavored sauce do not appear to present a problem with either microbial activity (in the dehydrated state) or rehydration because the water activity level of the whole mixture is controlled.

[0024] In the preferred embodiment, soy bean oil is provided at 16-18% by weight of the mixture. The soybean oil acts as a plasticizing agent to keep the product soft without relying upon moisture.

[0025] It is also contemplated that other hydrophillic and/or water soluble constituents may be beneficial to providing a shelf-stable relatively easily rehydratable sauce-like filling. For example, the pizza -flavored sauce disclosed herein includes salt which may be introduced directly or indirectly through addition of other salt-containing constituents, for example: the Ricotta, Parmesan and Romano cheeses;the margarine; and the breadcrumbs. The powdered forms of certain spices such as chili powder, oregano, onion, pepper, paprika, garlic, nutmeg, sage, and basil add flavoring tissue to the filling are compatible with desired drying.

[0026] As used herein, "sauce"or "sauce-like texture"are intended to distinguish from conventional pasta fillings having either a chunky or paste-like texture such as meat and/or cheese filled pastas, for example conventional ravioli.

[0027] Providing a pasta with an internally disposed sauce provides numerous advantages. For example, since the sauce is not released until the pasta is chewed, a unique taste and eating sensation is produced. Also, spillage of sauce on clothing, table surfaces, or the like, is reduced. Since the sauce is internal to the pasta: (1) cookware used to prepare the pasta is reduced to a single container as the sauce is cooked within the pasta; and, (2) the container used is more easily cleaned as the sauce does not have contact with the container surfaces.

[0028] While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention and the scope of protection is only limited by the scope of the accompanying Claims.
