Definitions

• This invention relates to high protein, low carbohydrate pastas, food compositions related thereto, and farinaceous food products made therefrom.
• High protein, low carbohydrate pastas for purposes of nutritional fortification or compliance to specific dietary regimens are known in the art (see ⁇ for example, U.S. Patents 3,949,101; 4,000,330; 4,120,989; and 6,322,826; and U.S. Patent Application 2002/0155206).
• such pastas have high amounts of dietary fiber, such that the texture of the cooked pasta is not similar to that of a traditional semolina-based pasta.
• these high protein, high fiber, low carbohydrate pastas have a firm, dry, abrasive texture that makes it less desirable to eat.
• Some protein-based pastas, which have extremely low amounts of fiber have a continuous protein network.
• pastas tend to be defectively firm, chewy, and rubbery in texture. Also, such high protein pastas require longer cook times in order for the pastas to soften. Moreover, the pastas of the prior art are often difficult to produce, as they are made from doughs that are sticky, firm, and prone to die obstruction, which limits the efficiency with which they can be produced with large scale manufacturing extruders. Furthermore, some high protein, low carbohydrate pastas are not stable in acidic sauces or dressings, such that they cannot be used in tomato-based sauces or vinegar-based dressings. Instead, these pastas curdle in acidic environments, thereby rendering them less palatable.
• the present invention provides high protein, low carbohydrate pastas that are also low in fiber. Specifically, a pasta comprising, by weight, at least about 55% protein, about 10% or less fiber, and at least about 4% fat is provided. The pastas also comprise less than about 30% total carbohydrate by weight.
• the pastas described herein include a rapid- cook pasta, a rice substitute, a gluten-free pasta, and a soy-milk based pasta.
• Such pastas differ from other high protein, low carbohydrate pastas of the prior art by having nearly the same properties of traditional semolina pastas with respect to manufacturing, home use, taste, and texture.
• the present invention also provides a pasta having at least about 55% protein, by weight, and having a firmness value that does not differ by more than 40% from that of 100% durum semolina wheat pasta.

Unlike other high protein pastas, the pastas provided herein boil like a traditional semolina wheat pasta, cooking in roughly the same amount of time. The present inventive pastas do not require an extended cooking time in order to have the same bite or texture as traditional semolina wheat pasta. Also, the pastas do not produce excessive foam and boil over when cooked.

• One such inventive food composition comprises, by weight, (i) about 10-20% glutinous protein, (ii) about 35-80% globular protein, (iii) starch, fat, or a combination thereof, and, optionally, (iv) buffering agent.
• the term "glutinous” as used herein refers to viscid, tenacious proteins, or substance(s) thereof, which give(s) adhesiveness to dough, allowing it to be a smooth, single, stretchy matrix.
• the glutinous protein can be a casein protein (e.g., a sodium caseinate) or a protein derived from a cereal grain.
• the protein derived from a cereal grain can be a wheat gluten, which is the glutinous protein normally used in traditional pastas. It is preferable that the glutinous protein is a wheat gluten. More preferably, the wheat gluten is wheat gluten that has been treated with lactic acid. Treated wheat gluten absorbs water better than untreated wheat gluten.
• globular refers to a protein that is colloidal and relatively inert.
• Globular protein can be soy protein, whey protein, lupin protein, or cooked, denatured and microparticulated protein of some other type.
• the selection of the globular protein appears to have an important influence on acid stability, cook time, and texture of the finished pasta product.
• Globular protein should be selected based on taste, low water binding capacity, and low solubility in boiling water.
• globular protein is a soy protein.
• Soy protein can be a soy protein that is derived from expeller pressed flour.
• the fat of the food composition described herein refers to any of various soft, solid, or semisolid organic compounds constituting the esters of glycerol and fatty acids and their associated organic groups.
• Fat includes any of the group of oily substances of natural occurrence, as butter, lard, tallow, etc. Fat can be, for instance, solidified animal oil or vegetable oil.
• the fat can be a finely divided fat, such as that bound to expeller pressed soy flour and protein derived therefrom.
• finely divided refers to fat that is colloidal but not necessarily in the form of a true emulsion. Emulsified fat, such as that present in soy milk, can also be used in the inventive composition.
• emulsified fat refers to that containing specific surfactants to support the emulsion.
• Emulsified fats are known in the art.
• the fat can be a combination of a finely divided fat or an emulsified fat.
• the fat is encapsulated spray-dried fat, emulsified plastic shortening, a protein-bound oil, or a combination thereof.
• the fat in the food compositions described herein reduces the friction during the extrusion step of the pasta manufacturing process.
• the fat also reduces the rubbery bite that is characteristic of glutenous high protein foods, perhaps by disruption of the protein network.
• the fat also lessens the textural changes in acidic conditions, e.g., tomato-based sauces, and the fat reduces the stickiness of pasta that improves the eating quality of the pasta.
• the food compositions of the present invention can optionally comprise a buffering agent.
• buffering agent as used herein is a substance that minimizes change in the acidity of a solution when an acid or base is added to a solution.
• buffering agents examples include calcium gluconate, lysine, citrate salt, phosphate salt, ethylendiamminetetraacetic acid, tris hydroxymethylaminoethane (TRIS buffer), lactate salt, ascorbate salt, a salt of a long chain fatty acid, or a combination thereof.

More preferably, the citrate salt is sodium citrate and the phosphate salt is dicalcium phosphate.
• Starch included in the inventive composition can be any complex carbohydrate found chiefly in seeds, fruits, tubers, roots and stem pith of plants, notably in corn, potatoes, wheat, and rice.
• Starch can be a flour, preferably wheat flour, corn flour, potato flour, rice flour, or tapioca flour.
• the flour of the food compositions described herein balances proper pasta extrusion during manufacture of the pasta and desirable texture and acid stability after cooking the pasta.
• Soy and wheat flours seem to enhance the textural stability in acidic conditions, perhaps by disruption of the protein network and addition of inert bulk that resists changes in the dough's structural matrix. Starch reduces extrusion friction and improves thixotropic die flow. Furthermore, the use of flour in the food compositions of the present invention reduces the cost of making the pastas, since refined proteins are more expensive. Surprisingly, it has been found that the amount of flour used in the present inventive food compositions is inversely related to the amount of fat needed for a desirable texture.
• the food composition of the present invention comprises, by weight, about 5-55% starch, about 4% or more fat, or a combination thereof. More preferably, the food composition comprises, by weight, about 8-30% starch, about 4-16% fat, or a combination thereof.

Drying can be performed overnight. Since protein pasta is less prone to surface defects like checking, protein pasta short goods can be dried in 45 minutes at 85°C and 15%RH in a vibrating fluid bed.
• This example illustrates a method of manufacturing pastas of the present invention using a twin-screw extruder.
• a twin-screw extruder such as an APV MPF 40 was also used. Protein Pasta dry blend was filled into a hopper and fed by a metering screw into the mouth of the extruder.

It also was very similar to semolina in sensory testing.
• Formulation Q was used to make pasta in accordance with Example 2. Water was added at approximately a 50-55% wt/wt ratio.
