ABSTRACT
Cereals are the most important crops in the world. They dominate world agricultural production since they directly or indirectly provide a large proportion of the human sustenance. About half of the plowed land in the world is used for growing the principal cereals. Cereal grains commonly contain 60-70% starch and 7-14% protein. They are the most important source of carbohydrates for humans and domestic animals, and also provide a substantial proportion of protein. Cereals are the staple foods for many people everywhere on the globe, particularly in the developing countries, because they are a relatively cheap source of calories and protein compared to meat.
