Abstract
Abstract A thickened foodstuff containing a starch extracted from a starch bearing plant having an amylose extender dull genotype is disclosed. Maize is the preferred plant. The starch exhibits low gelatinization temperature with an amylose content greater than 50%. A method for making the canned foodstuff containing the starch is also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
60 words
A thickened foodstuff for canning comprising a foodstuff, water and having as an essential ingredient therein an effective amount of a natural thin-thick starch, said starch extracted from a starch bearing plant having an amylose extender dull genotype, said starch providing no effective thickening characteristics to said foodstuff before canning while providing effective thickening characteristics to said foodstuff after canning.
Claim 2
Dependent Claim
60 words
A thickened foodstuff for canning comprising a foodstuff, water and having as an essential ingredient therein an effective amount of a natural thin-thick starch, said starch extracted from a starch bearing plant having an amylose extender dull genotype, said starch providing no effective thickening characteristics to said foodstuff before canning while providing effective thickening characteristics to said foodstuff after canning.
Claim 3
Dependent Claim
22 words
The thickened foodstuff of claim 1 wherein the starch bearing plant is maize and the starch is extracted from kernels of maize.
Claim 4
Dependent Claim
27 words
The thickened foodstuff of claim 1 wherein the amount of starch present is about 1% to about 20% by weight based on total weight of thickened foodstuff.
Claim 5
Dependent Claim
22 words
The thickened foodstuff of claim 3 wherein the starch bearing plant is maize and the starch is extracted from kernels of maize.
Claim 6
Dependent Claim
21 words
The method of claim 1 wherein the water and starch are combined together first and then subsequently combined with the foodstuff.
Claim 7
Dependent Claim
25 words
The method of claim 1 wherein the amount of starch added is about 1% to about 20% by weight based on total weight of foodstuff.
Claim 8
Independent Claim
66 words
A method for making a thickened foodstuff comprising combining a foodstuff, water and an effective amount of a natural thin-thick starch, said starch extracted from a starch bearing plant having an amylose extender dull genotype and subjecting said combination to a canning process whereby said starch provides no effective thickening characteristics to said foodstuff before scanning while providing effective thickening characteristics to said foodstuff after canning.
Claim 9
Independent Claim
66 words
A method for making a thickened foodstuff comprising combining a foodstuff, water and an effective amount of a natural thin-thick starch, said starch extracted from a starch bearing plant having an amylose extender dull genotype and subjecting said combination to a canning process whereby said starch provides no effective thickening characteristics to said foodstuff before scanning while providing effective thickening characteristics to said foodstuff after canning.
Claim 10
Dependent Claim
14 words
The method of claim 7 wherein the starch is extracted from a maize kernel.
Claim 11
Dependent Claim
8 words
The starch of claim 8 in granular form.
Claim 12
Dependent Claim
44 words
In a method of canning comprising combining a foodstuff, a starch and water, and subjecting the combination to a sterilization process, the improvement comprising the an effective amount of substantially pure starch extracted from a starch bearing plant having an amylose extender dull genotype.
Claim 13
Dependent Claim
44 words
In a method of canning comprising combining a foodstuff, a starch and water, and subjecting the combination to a sterilization process, the improvement comprising the an effective amount of substantially pure starch extracted from a starch bearing plant having an amylose extender dull genotype.
