Method for stabilizing wheat bran specially used for whole wheat flour

The invention discloses a method for stabilizing the wheat bran specially used for the whole wheat flour, which is mainly characterized in that: the wheat bran is treated by steam and dried by the ultraviolet microwave so that the wheat bran is stabilized. Due to the adoption of the method, the activity of the lipase and the lipoxygenase in the wheat bran can be reduced significantly, and the storage stability of the wheat bran can be improved significantly. In addition, the treated wheat bran has little difference from the non-stabilized wheat bran in colour and organoleptic quality, the content of total phenols in the treated wheat bran is increased slightly, and the antioxidant activity of the treated wheat bran is improved obviously. The method is simple and practical, has an obvious effect and effectively solves a series of problems of the existing method for stabilizing the wheat bran that the equipment has high cost, the operation process is burdensome and complicated, the wheat bran has poor storage stability, the colour of the stabilized wheat bran is dark, the efficacy and the activity are lost, and the stabilized wheat bran is not suitable for producing the whole wheat flour, thereby creating the conditions for producing the high-quality whole wheat flour with long shelf life.
