Crude Corn Oil: A transparent, light reddish-orange coloured liquid that displays the general physical characteristics of common corn oil. The odour of crude corn oil is free from any rancid, musty, paint-like, soapy, fishy or other off odours. The corn oil is clear and free of suspended matter. Valued for its high energy content crude corn oil is commonly used as a feedstock for biodiesel production or an ingredient in poultry rations. Greenfield is producing crude corn oil at our Chatham, Varennes & Johnstown plants. Shipped by truck, corn oil is sent to end users in Canada and the United States.
