Corn is the most relevant crop worldwide for volume production:
Yellow corn is the first worldwide grown. Few countries grow mainly White corn as México
Cereal wordwide production (1996-2006)Millions of tons.
Great use diversity Over 7000 industrialized food products contain chemical corn derivatives. Everyday we consume food products that likely contain starch, dextrose, high fructose …corn derivatives
