Abstract
Abstract A thickener is prepared comprising water and a waxy starch from a selected plant of a wxsu2 genotype, the sol of which starch exhibits superior resistance to breakdown on storage at low temperatures. The starch may optionally be modified. The thickener, which preferably employs a starch extracted from maize, is particularly useful for food applications.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
96 words
A process for preparing a thickened foodstuff comprising combining at least a foodstuff and a sol comprising water and an effective amount of a waxy starch from a plant of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, and cooking said combination as necessary to provide a thickened foodstuff, wherein said thickened foodstuff exhibits low-temperature stability and wherein said foodstuff prepared with said sol is capable of withstanding at lease one freeze-thaw cycle more than a foodstuff prepared with a native waxy starch from the respective plant which is not of a wxsu2 genotype.
Claim 2
Dependent Claim
96 words
A process for preparing a thickened foodstuff comprising combining at least a foodstuff and a sol comprising water and an effective amount of a waxy starch from a plant of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, and cooking said combination as necessary to provide a thickened foodstuff, wherein said thickened foodstuff exhibits low-temperature stability and wherein said foodstuff prepared with said sol is capable of withstanding at lease one freeze-thaw cycle more than a foodstuff prepared with a native waxy starch from the respective plant which is not of a wxsu2 genotype.
Claim 3
Dependent Claim
93 words
A process for preparing a thickened foodstuff comprising combining at least a foodstuff and a sol comprising water and an effective amount of a starch from a waxy maize of a wxsu2 genotype and translocations, inversions, mutants and variants thereof, and cooking said combination as necessary to provide a thickened foodstuff, wherein said thickened foodstuff exhibits low-temperature stability and wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy maize starch which is not of a wxsu2 genotype.
Claim 4
Dependent Claim
93 words
A process for preparing a thickened foodstuff comprising combining at least a foodstuff and a sol comprising water and an effective amount of a starch from a waxy maize of a wxsu2 genotype and translocations, inversions, mutants and variants thereof, and cooking said combination as necessary to provide a thickened foodstuff, wherein said thickened foodstuff exhibits low-temperature stability and wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy maize starch which is not of a wxsu2 genotype.
Claim 5
Dependent Claim
14 words
The process of claim 2 wherein said starch of the wxsu2 genotype is native.
Claim 6
Dependent Claim
14 words
The process of claim 2 wherein said starch of the wxsu2 genotype is crosslinked.
Claim 7
Dependent Claim
35 words
The process of claim 2 wherein said starch of the wxsu2 genotype is crosslinked with a crosslinking agent selected from the group consisting of epichlorohydrin, linear dicarboxylic acid anhydrides, acrolein, phosphorus oxychloride and trimetaphosphate salt.
Claim 8
Dependent Claim
35 words
The process of claim 5 wherein the amount of said crosslinking agent employed to crosslink said starch is at least 0.001% by weight of the starch and said starch is derivatized to contain substituent groups.
Claim 9
Dependent Claim
18 words
The process of claim 2 wherein said starch of the wxsu2 genotype is derivatized to contain substitutent groups.
Claim 10
Dependent Claim
25 words
The process of claim 7 wherein said starch is derivatized to form hydroxypropyl ether, phosphate, octenyl succinate, acetate or tertiary or quaternary amine ether derivatives.
Claim 11
Dependent Claim
74 words
A thickened low-temperature stable foodstuff comprising at least a foodstuff and a sol comprising water and an effective amount of a waxy starch from a plant of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy starch from the respective plant which is not of a wxsu2 genotype.
Claim 12
Dependent Claim
74 words
A thickened low-temperature stable foodstuff comprising at least a foodstuff and a sol comprising water and an effective amount of a waxy starch from a plant of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy starch from the respective plant which is not of a wxsu2 genotype.
Claim 13
Dependent Claim
71 words
A thickened low-temperature stable foodstuff comprising at least a foodstuff and a sol comprising water and an effective amount of a starch from a waxy maize of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy maize starch which is not of a wxsu2 genotype.
Claim 14
Dependent Claim
71 words
A thickened low-temperature stable foodstuff comprising at least a foodstuff and a sol comprising water and an effective amount of a starch from a waxy maize of a wxsu2 genotype, and translocations, inversions, mutants and variants thereof, wherein said foodstuff prepared with said sol is capable of withstanding at least one freeze-thaw cycle more than a foodstuff prepared with a native waxy maize starch which is not of a wxsu2 genotype.
Claim 15
Dependent Claim
18 words
The thickened foodstuff of claim 10 wherein said starch from waxy maize of a wxsu2 genotype is native.
Claim 16
Dependent Claim
18 words
The thickened foodstuff of claim 10 wherein said starch from waxy maize of a wxsu2 genotype is crosslinked.
Claim 17
Dependent Claim
22 words
The thickened foodstuff of claim 10 wherein said starch from waxy maize of a wxsu2 genotype is derivatized to contain substituent groups.
Claim 18
Dependent Claim
18 words
The thickened foodstuff of claim 10 wherein the foodstuff is a pie filling, tomato sauce, gravy or pudding.
