Publication number: 20120015093Abstract: A method provides a milled whole seed product from a whole seed having at least 0.01% by total weight of oil therein. The whole seed is added to an aqueous carrier which is physically milled at a shear rate of at least 3,000 r.p.m. The shearing is continued until at least 50% by weight of seed solids will pass through a square mesh screen having 1.2 mm screen hole dimensions.
