Maize contains essential nutrients such as carbohydrate and dietary fiber which provide adequate calorie required by the body [1]. Earlier reports showed that maize contains 7 to 13% protein, 1.4 to 6.0% fat, 74 to 80% carbohydrate, 0.81% ash and 414 kCal/100g of calorie 

Good quality maize is free from foreign odors, molds, live or dead pests, rat droppings (feces, urine and hairs) and other injurious contaminants. The maize should not contain levels of chemical residues higher than those recommended. Grain with musty smell or generally appearing moldy should be rejected.

The white flour is characterized by low content of proteins and glutens. The quality of wheat flour can be defined for several parameters including protein, moisture, gluten, sedimentation, enzyme activity, and rheological properties. Gluten consists of 90% protein, 8% lipids and 2% carbohydrates.
