The invention relates to the technical field of grain production, in particular to a
wheat flour processing method which comprises the following steps: cleaning and pretreating raw materials; subacid electrolyzed water stepped conditioning and wheat
wetting: subacid electrolyzed water with the effective
chlorine concentration of 5-30 ppm is used for carrying out at least two stages of wheat
wetting treatment on the wheat; low-temperature
grinding and fine grading: lightly
grinding and peeling the wetted wheat, and then
grinding in a low-temperature environment of 15-25 DEG C to obtain a peel-ground material, high-precision heart-ground
powder and wheat germs; performing
superfine grinding on the wheat germs, namely performing
superfine grinding on the wheat germs obtained in the step S3 to obtain superfine ground
wheat germ powder with the particle size D90 being less than or equal to 45 microns; optimizing and recombining taste and
nutrition, namely compounding the high-enrichment
aleurone layer
powder, the high-precision heart milling powder and the
superfine grinding wheat germ powder; wherein the high-enrichment
aleurone layer powder is obtained from the peel grinding material. The
wheat flour obtained by the method can meet the requirements of low
bacteria and mellow taste at the same time.
