Ruptured kernels


Ruptured kernels have a split in the bran that allows the endosperm to be exposed and quite often protrude. The Canadian Grain Commission considers wheat kernels to be ruptured when the split in the cheek extends at least half the length of the cheek or if both cheeks are split to any degree. Ruptured kernels do not require magnification to be identified. The following picture shows an example of ruptured kernels.
