Grains with keratin accounting for more than 1/2 of the cross section of the wheat grain are keratin grains; However, the cross section is 1/2, and the particles with less keratin are powdery plasmids. China stipulates that more than 70% of horny grains in a batch of raw grains are hard wheat, and more than 70% of powdery plasmids are soft wheat.
