Germ contributes about 11% of the kernel weight, contains 45-50% oil and about 85% of the oil kernel. The germ is a distinct entity that can be easily separated and then extracted to produce maize oil, yielding maize germ oil meal as the main by-product. Germs are removed in the wet milling process to facilitate starch extraction, whereas they are removed in the dry milling process to improve the stability of maize grain products for use as food.
