The raw corn for wet milling should contain 1516 per cent moisture and it should be physically sound. Insect and pest infested, cracked and heat damaged corns (treated at temperature around 75ᵒC during drying) are unsuitable for wet milling. The heat damaged corn affects the quality of oil extracted from its germ.
