Claim 10
Independent Claim
31 words
A method for producing a substantially pure starch from a maize plant having a dull horny genotype comprising wet milling kernels of said maize plant to obtain said substantially pure starch.
Claim 11
Independent Claim
31 words
A method for producing a substantially pure starch from a maize plant having a dull horny genotype comprising wet milling kernels of said maize plant to obtain said substantially pure starch.
Claim 12
Dependent Claim
30 words

Claim 13
Independent Claim
53 words
A method for making a sol with a substantially pure starch from a plant having a dull horny genotype comprising forming a slurry comprising water and an effective amount of substantially pure starch extracted from a starch bearing plant having a dull horny genotype; and cooking said slurry as necessary to produce sol.
Claim 14
Independent Claim
53 words
A method for making a sol with a substantially pure starch from a plant having a dull horny genotype comprising forming a slurry comprising water and an effective amount of substantially pure starch extracted from a starch bearing plant having a dull horny genotype; and cooking said slurry as necessary to produce sol.
