A few days ago, when I was eating in a restaurant, I heard from a friend that the Qiao noodles in Chifeng began to be mixed with a kind of black noodles. Bad for people, right? Who knows about this? Tell me about it. Black face does little harm to human body. I don't know what you mean by bad face! The first difference of black flour is the difference of processing procedures: after wheat is produced, it is ground after rough processing such as peeling, and then coarse flour, which is often called black flour, comes out; After grinding for a few more times, white flour will come out. The second difference is the difference in proportion: in early years, ordinary people ate mixed noodles instead of simple coarse noodles. Mix the noodles of coarse grains such as bean noodles, corn noodles and sweet potato noodles to eat together. Therefore, when coarse flour is mixed with other flours such as soybean flour and corn flour in proportion, it is also called black flour.
