Visual Reference Library - Wheat

Kernels and pieces of kernels of wheat that are significantly discolored to the extent shown are heat damage. Whole kernels may need cross-sectioning to confirm that the face of BOTH halves are as dark as shown in Kernel A or B. A kernel with a combination of vitreous and creamy discoloration meeting the reference is heat damage.
Kernel A: The minimum discoloration for cross-sectioned vitreous kernels.
Kernel B: The minimum discoloration (creamy) for cross-sectioned non-vitreous kernels.
Kernel C: A suspect kernel that requires cross-sectioning.

The visual reference images can be downloaded from our eBook Page. Information for purchasing printed copies of the visual references can be found on our Merchandise Page.
