Wheat middlings, starch < 20%

Byproduct of wheat flour production obtained by the milling of wheat grains (Triticum aestivum L., also known as Triticum aestivum L. subsp. aestivum). It consists principally of fragments of the outer skins and of particles of grain containing variable amounts of endosperm. Wheat middlings are often mixtures of different types of milling offal. They are typically richer in starch and less coarse than wheat bran, and poorer in starch and coarser than wheat feed flour. The composition and nutritive values are provided for wheat middlings containing less than 20% starch (as fed).
