Abstract
Abstract A dough composition for making quality, thinly sheeted farinaceous food products such as pie crust or the like and which is shelf stable. The dough composition contains a high-starch, low-enzyme flour, shortening, water, gluten and preservatives. The composition is particularly adapted for making a pie dough which, during manufacture, is pre-sheeted and folded twice for packaging, and then is unfolded by the consumer for use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A method of processing dough to improve baked flakiness, said method comprising: mixing flour, shortening and water and thereby form a dough mass, said shortening being in an amount sufficient to provide flakiness in a cooked product made from said dough mass; exposing said dough mass to a reduced pressure environment wherein the vacuum pressure is at least about 27.5 inches of mercury, said exposure is for a time of at least about 1/2 second with said time being that time period for which the vacuum pressure is at least equal to the specified vacuum pressure, during said exposing, said dough is allowed to volumetrically expand at least about 1.1 times its pre-exposure volume; and releasing said vacuum prior to commencement of cooking.
Claim 2
Independent Claim
123 words
A method of processing dough to improve baked flakiness, said method comprising: mixing flour, shortening and water and thereby form a dough mass, said shortening being in an amount sufficient to provide flakiness in a cooked product made from said dough mass; exposing said dough mass to a reduced pressure environment wherein the vacuum pressure is at least about 27.5 inches of mercury, said exposure is for a time of at least about 1/2 second with said time being that time period for which the vacuum pressure is at least equal to the specified vacuum pressure, during said exposing, said dough is allowed to volumetrically expand at least about 1.1 times its pre-exposure volume; and releasing said vacuum prior to commencement of cooking.
Claim 3
Dependent Claim
27 words
A method of processing dough to improve baked flakiness as set forth in claim 1 wherein: said vacuum pressure is at least about 28 inches of mercury.
Claim 4
Dependent Claim
27 words
A method of processing dough to improve baked flakiness as set forth in claim 2 wherein: said vacuum pressure is at least about 29 inches of mercury.
Claim 5
Dependent Claim
31 words
A method of processing dough to improve baked flakiness as set forth in claim 1, 2 or 3 wherein said volumetric expansion is at least about 1.5 times the pre-exposure volume.
Claim 6
Dependent Claim
37 words
A method of processing dough to improve baked flakiness as set forth in claim 4 including storing the dough wherein the thus exposed dough during storage is maintained in a gaseous environment substantially comprising CO 2 .
Claim 7
Dependent Claim
37 words
A method of processing dough to improve baked flakiness as set forth in claim 4 including storing the dough wherein the thus exposed dough during storage is maintained in a gaseous environment substantially comprising N 2 O.
Claim 8
Independent Claim
111 words
A method of processing dough to improve baked flakiness, said method comprising: mixing flour, shortening and water and thereby form a dough mass wherein said dough mass has shortening in an amount of at least about 24% by weight; exposing said dough mass to a reduced pressure environment wherein the vacuum pressure is at least about 27.5 inches of mercury, said exposure is for a time of at least about 1/2 second with said time being that time period for which the vacuum pressure is at least equal to the specified vacuum pressure, during said exposing, said dough is allowed to volumetrically expand at least about 1.1. times its pre-exposure volume.
Claim 9
Independent Claim
111 words
A method of processing dough to improve baked flakiness, said method comprising: mixing flour, shortening and water and thereby form a dough mass wherein said dough mass has shortening in an amount of at least about 24% by weight; exposing said dough mass to a reduced pressure environment wherein the vacuum pressure is at least about 27.5 inches of mercury, said exposure is for a time of at least about 1/2 second with said time being that time period for which the vacuum pressure is at least equal to the specified vacuum pressure, during said exposing, said dough is allowed to volumetrically expand at least about 1.1. times its pre-exposure volume.
Claim 10
Dependent Claim
27 words
A method of processing dough to improve baked flakiness as set forth in claim 7 wherein said vacuum pressure is at least about 28 inches of mercury.
Claim 11
Independent Claim
30 words
A method of processing dough to improve baked flakiness as set forth in claims 7 or 8 wherein said volumetric expansion is at least about 1.5 times the pre-exposure volume.
