Abstract
Abstract An expanded farinaceous food product is produced without the use of a drying apparatus. A farinaceous food mixture containing from about 5 weight percent to about 17 weight percent of at least one plasticizer selected from monosaccharides, polysaccharides, and edible alcohols and having a moisture content of from about 9% to about 17% is plasticized in an extruder barrel having a barrel pressure equal to or in excess of the vapor pressure of the water in the mixture; and the plasticized mixture is extruded through a profile die into a zone of ambient pressure below the vapor pressure of the water in the mixture.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A method for producing an expanded, farinaceous food product without the use of a drying oven which comprises plasticizing a farinaceous food mixture containing from about 5 weight percent to about 17 weight percent of at least one plasticizer selected from monosaccharides, polysaccharides, and edible alcohols and having a moisture content from about 9 weight percent to about 17 weight percent in an extruder barrel having a barrel pressure equal to or in excess of the vapor pressure of the water in the mixture; and extruding the plasticized mixture through a profile die into a zone of ambient pressure below the vapor pressure of the water in the mixture, thereby producing a crisp product having a moisture content from about 4 weight percent to about 8 weight percent and a water activity from about 0.30 to about 0.45.
Claim 2
Independent Claim
138 words
A method for producing an expanded, farinaceous food product without the use of a drying oven which comprises plasticizing a farinaceous food mixture containing from about 5 weight percent to about 17 weight percent of at least one plasticizer selected from monosaccharides, polysaccharides, and edible alcohols and having a moisture content from about 9 weight percent to about 17 weight percent in an extruder barrel having a barrel pressure equal to or in excess of the vapor pressure of the water in the mixture; and extruding the plasticized mixture through a profile die into a zone of ambient pressure below the vapor pressure of the water in the mixture, thereby producing a crisp product having a moisture content from about 4 weight percent to about 8 weight percent and a water activity from about 0.30 to about 0.45.
Claim 3
Dependent Claim
25 words
A method as claimed in claim 1, wherein the plasticizer is selected from the group consisting of maltodextrin, polydextrose, sucrose, corn syrup solids, and glycerol.
Claim 4
Dependent Claim
55 words
A method as claimed in claim 1, wherein the plasticizer is a mixture containing from about 4% to about 6% corn syrup solids, from about 3% to about 6% polydextrose, from about 0.5% to about 2% sucrose, and from about 0.5% to about 2.5% glycerol, based on the total weight of the farinaceous food mixture.
Claim 5
Dependent Claim
48 words
A method as claimed in claim 1 comprising adding as the plasticizer from about 6 weight percent to about 15 weight percent, based on the total weight of the farinaceous food mixture, one or more of the group consisting of sucrose, maltose, fructose, dextrose, polysaccharides, and edible alcohols.
Claim 6
Dependent Claim
26 words
A method as claimed in claim 1, wherein the farinaceous food mixture is plasticized by contacting it with co-rotating twin extruder screws in the extruder barrel.
Claim 7
Dependent Claim
44 words
A method as claimed in claim 1, wherein the farinaceous food mixture contains at least one material selected from the group consisting of meals, flours, and starches derived from corn, wheat, rice, oats, barley, potatoes, rye, tapioca and other cereal crops, legumes, and tubers.
Claim 8
Independent Claim
13 words
A method as claimed in wherein the farinaceous food mixture contains corn meal.
Claim 9
Dependent Claim
47 words
A crisp, expanded, farinaceous food product, having a moisture content from about 4 weight percent to about 8 weight percent and a water activity of from about 0.30 to about 0.45, which is produced by the process of claim 1, 2, 3, 4, 5, 6, or 7.
Claim 10
Dependent Claim
46 words
A composite food product comprising a crisp, expanded, farinaceous outer shell comprising a material which is produced by the process of claim 1, 2, 3, 4, 5, 6, or 7, and an inner, flavored filling material, said outer shell having a generally annular or C-shaped cross-section.
Claim 11
Dependent Claim
18 words
A composite food product as claimed in claim 9, wherein the inner, flavored filling material is cheese flavored.
Claim 12
Dependent Claim
20 words
A composite food product as claimed in claim 9 wherein the inner, flavored filling material is a sweet confectionary filling.
