Abstract
Abstract A process for producing instant-cooking pasta products such as noodles, spaghetti, macaroni and the like having a porous, cellular structure which enables the products to be rehydrated for consumption within a short period of time, and which exhibit good integrity, firm texture, and desirable flavor upon rehydration. A blend containing a major proportion by weight of a farinaceous starch-containing ingredient, such as semolina, and lesser amounts of gluten, microcrystalline cellulose and an edible vegetable oil is introduced into an extrusion cooker together with a sufficient amount of water to provide an expandable mixture. The mixture is subjected to severe mechanical working at elevated temperatures and pressure to rapidly cook the mixture, causing gelatinization of the starch and thermosetting of the gluten, and is extruded through a plurality of die orifices into the atmosphere. Upon extrusion, the pasta expands forming a pasta product having a porous cellular structure, which is subsequently dried to a maximum moisture content of about 10%. Due to the porous cellular structure of the product, it is readily rehydrated by contact with hot water for a short period of time. Because of the combination of ingredients used, the product, upon rehydration, has good integrity and firm texture without becoming pasty or sticky.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
228 words
A process of producing instant cooking pasta products having a porous, cellular structure which consists essentially of forming a particulate mixture containing a major proportion by weight of a farinaceous starch-containing material, from 1% to 26% by weight of gluten, from 0.25% to 0.75% by weight of microcrystalline cellulose, between 1% to 3.5% by weight of an edible vegetable oil, and from 0%-less than 2% of a phosphatide, introducing the particulate mixture into an extrusion cooker together with an amount of water sufficient to provide an expandable mixture capable of being carried through the extrusion cooker, subjecting said expandable mixture to severe mechanical working under temperatures sufficiently high to cook the mixture, thereby gelatinizing the starch and thermosetting the gluten contained therein, and pressure sufficiently high that the pressure drop across the die orifice will result in flashing off of water in the mixture as steam, extruding the hot, pressurized mixture through a plurality of die orifices into atmospheric conditions, thereby expanding the cooked material by flashing of contained water to steam, and drying the extruded product to a maximum moisture content of about 10%, thereby producing an expanded product having a porous cellular structure which may be hydrated for consumption by contact with hot water for a short period of time and which upon hydration has a firm texture and good integrity without becoming pasty or sticky.
Claim 2
Dependent Claim

A process of producing instant cooking pasta products having a porous, cellular structure which consists essentially of forming a particulate mixture containing a major proportion by weight of a farinaceous starch-containing material, from 1% to 26% by weight of gluten, from 0.25% to 0.75% by weight of microcrystalline cellulose, between 1% to 3.5% by weight of an edible vegetable oil, and from 0%-less than 2% of a phosphatide, introducing the particulate mixture into an extrusion cooker together with an amount of water sufficient to provide an expandable mixture capable of being carried through the extrusion cooker, subjecting said expandable mixture to severe mechanical working under temperatures sufficiently high to cook the mixture, thereby gelatinizing the starch and thermosetting the gluten contained therein, and pressure sufficiently high that the pressure drop across the die orifice will result in flashing off of water in the mixture as steam, extruding the hot, pressurized mixture through a plurality of die orifices into atmospheric conditions, thereby expanding the cooked material by flashing of contained water to steam, and drying the extruded product to a maximum moisture content of about 10%, thereby producing an expanded product having a porous cellular structure which may be hydrated for consumption by contact with hot water for a short period of time and which upon hydration has a firm texture and good integrity without becoming pasty or sticky.
Claim 3
Dependent Claim
39 words
The process defined in claim 1 in which the farinaceous material is selected from the group consisting of semolina, durum flour, farina flour, and combinations thereof, with the farinaceous material comprising about 60% by weight of the particulate mixture.
Claim 4
Dependent Claim
29 words
The process defined in claim 2 in which the farinaceous material includes from 1% to 10% of a cereal flour having an indigeneous oil content of more than 5%.
Claim 5
Dependent Claim
14 words
The process defined in claim 3 in which the cereal flour is oat flour.
Claim 6
Dependent Claim
21 words
The process defined in claim 1 in which the particulate mixture contains between 0.4% to 0.6% by weight of microcrystalline cellulose.
Claim 7
Dependent Claim
15 words
The process defined in claim 1 in which the edible vegetable oil is corn oil.
Claim 8
Dependent Claim
22 words
The process defined in claim 1 in which the particulate mixture contains from about 1% to 2% of a starch complexing agent.
Claim 9
Dependent Claim
25 words
The process defined in claim 7 in which the starch complexing agent is selected from the group consisting of glyceryl monostearate and mono- and diglycerides.
Claim 10
Dependent Claim
23 words
The process defined in claim 1 in which the phosphatide is lecithin which is present in an amount of about 0.1%-0.2% by weight.
Claim 11
Dependent Claim
28 words
The process defined in claim 1 in which the amount of water is sufficient to provide the particulate mixture with a moisture content of about 15% to 35%.
Claim 12
Dependent Claim
36 words
The process defined in claim 1 in which the hot pressurized mixture is extruded through a die plate having from 50 to 150 orifices, with the orifices having a diameter of between 0.05 and 0.2 inch.
