Refined flour generally refers to high-gluten flour, but it also refers to the fineness of wheat flour.

The production process of refined flour is more complicated, and the flour yield is much lower than that of ordinary flour. Wheat husk must be peeled several times before it can be ground into fine wheat flour. Its quality is meticulous, its residue is very little, its color is white, and its market price is much higher than that of wheat flour. Refined powder destroyed many nutrients when it was made. Although the taste is delicate, it can't be eaten for a long time.
