Oat groats, like wheat flour, contains oils in the whole form which will oxidize and cause it to go rancid. So how do pre-packaged oats stay fresh? Below is a great visual from Breatopia.com, our supplier, for our Mockmill Stone Grain Mills and Flaker Lovers Flaker.
Whether you are making up oatmeal, granola, oats for cookies or our oatmeal bake, there is nothing like freshly flaked oats. The Simply Filled Pantry is happy to flake our beautiful U.S. grown oats just for you so you get this benefit. You may get hooked and want to add a flaker to your kitchen tools. This one is electric, small and quick to go from oat groat to flaked oats.
Take a look at what's lost using commercially processed oats and keep in mind that you can also coarse mill (with a blender or stone mill) for oat meal, mill to flour for baking or flake for granola and so much more!
