Processing discolored (stained) oats reduce rolled oat yields and may result in a less than desirable flake color, depending on its severity. Oat groats having a dark brown/black discoloration on the surface meeting the minimum coverage and intensity as shown are considered damaged.
Illustration shows from left to right:
A. Suspect Oat: Slightly discolored hulls indicate possible damage. The hull must be removed to confirm the presence and extent of discoloration.
B. Confirmed Damage: Illustrates the minimum coverage and intensity requirement.
