Absolutely not!!!
Corn Flakes (as in the cereal) are a processed food product that contains corn. Flaked maize (or any grain for that matter) is the raw grain that has been passed through rollers at a high temp. The two products do not even resemble each other. Flaked maize resembles oatmeal if anything.
Wikipedia lists Corn Flakes ingredients as:
* Milled Corn, Sugar, Malt flavoring, High fructose corn syrup, Salt, Iron, Niacinamide, Sodium ascorbate and ascorbic acid (vitamin C), Pyridoxine hydrochloride (vitamin B6), Riboflavin (vitamin B2), Thiamin hydrochloride (vitamin B1), Vitamin A palmitate, Folic acid, Vitamin B12, Vitamin D, Vitamin B
There is no such thing as non gelatinized flaked maize. The rolling of the grain creates friction and heat, thus gelatizining it. The point of buying flaked grains is that you don't have to do a special mash to gelatinize the starches.
Grits are raw corn, but you have to cook them before adding to the mash.
