A process for producing an ultrafine-milled whole-grain wheat flour which has the full nutritional value of wheat kernels, while retaining the texture of refined wheat flour and an appearance similar to refined wheat flour, and the products which can be made from the ultrafine-milled whole-grain wheat flour. The process can also be used for producing an ultrafine-milled coarse fraction, which can be used as a replacement and to fortify refined wheat flour. The ultrafine-milled coarse fraction can be used in bakery products, snack products and food products.

What is claimed is: 1. A continuous flow grain milling process for producing a milled coarse fraction, comprising the steps of: (a) offering a quantity of cleaned and tempered wheat kernels; (b) milling the wheat kernels into a fine fraction, consisting essentially of endosperm and a coarse fraction comprising bran and germ; (c) separating the fine fraction from the coarse fraction; and (d) separately milling the coarse fraction in a gap mill having a conical rotor to form a milled coarse fraction, wherein the milled coarse fraction of step (d) contains substantially all the bran and germ of an unmilled coarse fraction of step (c), and wherein the milled coarse fraction has a particle size distribution such that greater than 98% passes through a U.S. 70 wire screen. 2. A process for producing an edible product comprising: (a) obtaining a quantity of a milled coarse fraction of wheat prepared according to the process of claim 1; and (b) mixing at least a portion of the quantity of the obtained milled coarse fraction with additional ingredients to produce an edible product comprising the milled coarse fraction. 3.
