Dependent Claim
32 words
A foodstuff comprising a foodstuff, and having as an essential ingredient therein an effective amount of substantially pure starch extracted from a starch bearing plant having an amylose extender dull shrunken-1 genotype.
Claim 9
Independent Claim
33 words
A method for producing a substantially pure starch from a maize plant having an amylose extender dull shrunken-1 genotype comprising wet milling kernels of said maize plant to obtain said substantially pure starch.
Claim 10
Independent Claim
33 words
A method for producing a substantially pure starch from a maize plant having an amylose extender dull shrunken-1 genotype comprising wet milling kernels of said maize plant to obtain said substantially pure starch.
Claim 11
Dependent Claim
30 words
