Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
117 words
A process for removing the off-taste in cereal starches comprising the steps of: (a) dispersing and agitating a sufficient quantity of a cereal starch in water so as to form a homogenous starch slurry that is between about 18 and 45%, by weight, starch; (b) adding an alkali to the slurry so that the slurry pH is no more than about 2 pH units from the starch's pasting pH; (c) within about 5 hours of the alkali addition, removing the alkali liquid from the slurry; (d) repeatedly washing the starch solids with an aqueous media, wherein the aqueous media does not substantially lower the starch pH below a pH of about 10; and (e) drying the slurry.
Claim 2
Dependent Claim
117 words
A process for removing the off-taste in cereal starches comprising the steps of: (a) dispersing and agitating a sufficient quantity of a cereal starch in water so as to form a homogenous starch slurry that is between about 18 and 45%, by weight, starch; (b) adding an alkali to the slurry so that the slurry pH is no more than about 2 pH units from the starch's pasting pH; (c) within about 5 hours of the alkali addition, removing the alkali liquid from the slurry; (d) repeatedly washing the starch solids with an aqueous media, wherein the aqueous media does not substantially lower the starch pH below a pH of about 10; and (e) drying the slurry.
Claim 3
Dependent Claim
29 words
A process according to claim 1 wherein the pH of the starch slurry after the addition of the alkali is within 1 pH unit of the starch's pasting pH.
Claim 4
Dependent Claim
42 words
A process according to claim 1 wherein the pH of the starch slurry after the addition of the alkali is within 0.5 pH units of the starch's pasting pH and the starch slurry is washed within 1 hour of the alkali addition.
Claim 5
Dependent Claim
18 words
A process according to claim 1 wherein the starch slurry is dried under conditions which gelatinize the starch.
Claim 6
Dependent Claim
40 words
A process according to claim 1 which further comprises the step of adding a neutralizing agent to the washed starch so as to adjust the starch pH so that it is above about pH 6 and below about pH 10.
Claim 7
Dependent Claim
16 words
A process according to claim 1 which further comprises the step of chemically modifying the starch.
Claim 8
Dependent Claim
21 words
A process according to claim 3 wherein the cereal starch is wheat starch and the pasting pH is about pH 12.4.
Claim 9
Dependent Claim
22 words
A process according to claim 3 wherein the cereal starch is dent corn starch and the pasting pH is about pH 12.5.
Claim 10
Dependent Claim
22 words
A process according to claim 2 wherein the cereal starch is waxy maize starch and the pasting pH is about pH 12.4.
Claim 11
Dependent Claim
18 words
A process according to claim 4 wherein the starch is pregelatinized by spray drying the neutralized starch slurry.
Claim 12
Dependent Claim
17 words
A process according to claim 4 wherein the starch is pregelatinized by drum drying the neutralized starch.
Claim 13
Dependent Claim
9 words
The product produced by the process of claim 1.
Claim 14
Dependent Claim
19 words
An instant dessert product wherein the ingredients include a pregelatinized cereal starch prepared by the process of claim 4.
Claim 15
Dependent Claim
20 words
A process according to claim 1 wherein the starch solids are washed at least four times with said aqueous media.
Claim 16
Dependent Claim
25 words
A process according to claim 1 wherein the alkali liquid is removed from the slurry within 1 hour of the alkali addition to the slurry.
Claim 17
Dependent Claim
28 words
A process according to claim 1 wherein the alkali liquid is removed from the slurry within about 1/2 hour of the addition of the alkali to the slurry.
