Abstract
Abstract A bland-tasting starch is prepared by stirring a starch having a distinct cereal or root taste in aqueous slurry form with an acid at about pH 3-5 for at least about 25 minutes, adding an alkaline earth metal oxide to a pH of 5.5 to 8 and stirring, and thereafter filtering the slurry and drying the starch. In a preferred aspect the acid is sulfuric acid, the oxide is calcium or magnesium oxide and the starch is waxy maize. When the starch is dried by drum-drying, a pregelatinized starch is obtained. The resulting starch will not adversely affect the taste of foodstuffs to which it is added.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
92 words
A process for treating starch to remove a cereal or root taste therefrom comprising the steps of stirring a starch having a distinct cereal or root taste in aqueous slurry form with an acid at about pH 3 to 5 for at least about 25 minutes; adding a sufficient amount of an alkaline earth metal oxide to the slurry to bring the pH thereof to 5.5 to 8, and stirring for at least about 15 minutes; filtering the slurry; and drying the resultant treated starch, thereby improving the flavor of said starch.
Claim 2
Dependent Claim
92 words
A process for treating starch to remove a cereal or root taste therefrom comprising the steps of stirring a starch having a distinct cereal or root taste in aqueous slurry form with an acid at about pH 3 to 5 for at least about 25 minutes; adding a sufficient amount of an alkaline earth metal oxide to the slurry to bring the pH thereof to 5.5 to 8, and stirring for at least about 15 minutes; filtering the slurry; and drying the resultant treated starch, thereby improving the flavor of said starch.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein said starch is selected from the group consisting of sorghum, potato and waxy maize starch.
Claim 4
Dependent Claim
83 words
A process for treating waxy maize starch to remove the cereal taste therefrom comprising the steps of stirring said starch in aqueous slurry form with an acid at about pH 3 to 5 for at least about 25 minutes; adding sufficient amount of alkaline earth metal oxide to the slurry to bring the pH thereof to 5.5 to 8, and stirring for at least about 15 minutes; filtering the slurry; and drying the resultant treated starch, thereby improving the flavor of said starch.
Claim 5
Dependent Claim
83 words
A process for treating waxy maize starch to remove the cereal taste therefrom comprising the steps of stirring said starch in aqueous slurry form with an acid at about pH 3 to 5 for at least about 25 minutes; adding sufficient amount of alkaline earth metal oxide to the slurry to bring the pH thereof to 5.5 to 8, and stirring for at least about 15 minutes; filtering the slurry; and drying the resultant treated starch, thereby improving the flavor of said starch.
Claim 6
Dependent Claim
25 words
The process of claim 1 wherein a sufficient amount of said oxide is added to bring the pH of said slurry to 6.5 to 7.5.
Claim 7
Dependent Claim
19 words
The process of claim 1 wherein said acid is sulfuric acid and said oxide is calcium or magnesium oxide.
Claim 8
Dependent Claim
20 words
The process of claim 1 wherein said drying is carried out in a drum drier to produce a pregelatinized starch.
Claim 9
Dependent Claim
12 words
The process of claim 1 wherein said starch is derivatized and/or crosslinked.
Claim 10
Dependent Claim
12 words
The process of claim 3 wherein said starch is derivatized and/or crosslinked.
Claim 11
Dependent Claim
9 words
A starch prepared by the process of claim 1.
Claim 12
Dependent Claim
9 words
A starch prepared by the process of claim 3.
Claim 13
Dependent Claim
9 words
A starch prepared by the process of claim 7.
Claim 14
Dependent Claim
9 words
A foodstuff containing therein the starch of claim 9.
Claim 15
Dependent Claim
9 words
A foodstuff containing therein the starch of claim 10.
Claim 16
Dependent Claim
9 words
A foodstuff containing therein the starch of claim 11.
Claim 17
Dependent Claim
13 words
The foodstuff of claim 14 wherein said foodstuff is a gravy or pudding.
