175 results of people/dogs/hamsters eating corn... what a fantasticly helpful suggestion.
back on topic...
corn kernels contain around 3.7% oil by weight. its not really fesable to extract that oil on the type of small scale we are talking about, in the same way that big production facilities do it.
it might be possible though to make a separate "corn mash", and either skim off, or just exclude, the top inch of liquid where the majority of the oil should float (being lighter than water). you would have to do some experiments and determine the best method, but it would be an interesting thing to try. if you could reduce that oil content by 90%, you would be left with around 0.3% corn oil by weight, which i dont think would have a huge impact on the beer; especially if the corn is not a large % of the total grain bill.
and actually, corn oil by weight is around 30% oleic acid, which is a great food for yeast cells. so if you get the oil content down low enough, the remaining residue should be broken down even furthur by the yeast themselves.
