Thanks for your very informative response post. As with any investment, one must be concerned with potential competition, and your comment on flax oil evokes this question....is it feasible/possible to economically reduce/remove the omega-6 oil in flax so that it could potentially assume omega-3 market share from menhaden? Thanks again, and if you have a good source for my own research on this topic, I would also appreciate that.
Anything is technically possible. The question is feasible. To reduce the omega-6 fatty acids, you would, first, have to selectively split the omega-6 acids from the triglyceride molecule, then remove it from the mass of oil. Removing it could be accomplished by conventional refining methods. The tricky part is splitting the omega-6's off while NOT splitting the omega-3's. And, there in lies the rub.
If you're looking for one source for all your answers, I doubt you will be successful. I use half a dozen different search engines, a a few well selected key words or key word combinations.
