Process for the production of refined whole wheat flour with low coloration

摘要

A whitish whole-wheat flour and a process for producing the flour are described wherein the wheat bran is separated into a fine bran and a coarse bran fraction and the course bran is pulverized to a smaller size and mixed into the flour.

主权项

1. A method for obtaining a refined whole-wheat flour, which comprises the steps of:
(a) supplying a quantity of wheat grain suitable for milling; (b) fractionating the wheat grain to obtain endosperm, bran, and germ; (c) separating and distributing the endosperm, bran, and germ; (d) milling the endosperm that is obtained in step (c) to obtain a particle size of approximately 150-180 microns; (e) treating the germ to reduce the reactivity of lipolytic enzymes which act on lipids contained therein; (f) treating the bran obtained in step (c) by:
(i) separating the stream of bran coming from step (c) in order to produce a fine bran and a coarse bran, and(ii) milling the coarse bran from step (i) in order to obtain a pulverized bran with a particle diameter of approximately 180 microns; (g) mixing the endosperm from step (d), the germ from step (e), the fine bran from step (f-i), and the pulverized bran from step (f-ii) in order to obtain a whole-wheat flour that consists of approximately 80.0% endosperm, approximately 17.5% bran, and approximately 2.5% germ and wherein said refined whole-wheat flour has L value on the Hunter scale, Illuminant D65, of 84-86.
