Wheat are some varieties
Hard Red Winter, Hard Red Spring, Soft Red Winter, Durum, Hard White, and Soft White
The two main types of wheat are common wheat or Triticum aestivum vulgare and durum wheat or Triticum turgidum durum.
Wheat is a grain that is high in carbohydrates, protein, fiber, minerals, and antioxidants. Wheat products include wheat germ,
spelt, couscous, bulgur, and wheat starch
Milling wheat
11% minimum protein, 12% maximum moisture content, 3% maximum damaged kernels, 2% maximum foreign material,
9.5% minimum gluten, 24% minimum wet gluten, 4.0% maximum total damaged kernels, 5.0% maximum shrunken and
broken kernels, 5.0% maximum total defects, 2.0% maximum total other classes, 0.7% maximum foreign material,
1.5% maximum dockage, 58 lbs per bushel test weight, 80% minimum vitreous amber kernels
10.5% minimum protein, 14% maximum moisture, 1.5% maximum foreign matter, 1.0% maximum heat damaged kernels, 2.0% maximum
total damaged kernels, 0.2% maximum smutty kernels, 0.5% maximum weevil kernels
Hard wheat flours had a higher volume fraction of particles ranging above
120 μm at elevated temperature. Our results suggest that the difference
in size of single particles and starch–protein aggregates, when comparin
soft and hard wheat flour, is due to the strength of starch–protein interactions

wheat particle size
The average particle size of hard wheat whole flours is 384–795 µm, while
soft wheat whole flours range from 455–2361 µm. The particle size index (PSI)
