What is Flint kernel?
In flint kernels, hard starch surrounds most of the kernel and soft starch is confined to a small area in the centre. As a result the crown does not dent as the kernel dries, and the surface looks glossy.
Flint kernels are generally harder and relatively resistant to breakage and storage pests. They come in colours such as yellow, orange or red. Some varieties show traits between the dent and flint types.
Why does it matter when choosing seed?
Kernel hardness affects milling, processing and storage behaviour. For buyers or processing methods that want flinty, coloured grain, kernel type is one of the deciding criteria when choosing a variety.
