Comparison of nutritional value of protein parts of processed grains (wheat, barley and corn) using the Cornell Net Carbohydrate and protein System (CNCPS) technique

The aim of this study was to determin the nutritive value of wheat, barley and corn using different processing methods and determination of nutritive value of protein using CNCPS method after milling, rolling, steam flacking or pelleting. In the processing cereals, the highest crude protein in )percentage of dry matter( belong to dry rolled wheat (14.2), rolled barley (12.6) and pelleted corn (9.5) respectively. The minimum amount of A part of protein belong to pelleted wheat (0.8) milled barley (0.5) and steam flacked corn (0.1) respectively. The maximum amount of B1 part of protein belong to pelleted wheat (6.5), dried roll barley (8.2) and pelleted corn (6.4) respectively. The maximum amount of B2 part belong to dried roll wheat (6.7), pelleted barley (4.4) and pelleted corn (2.5) respectively and maximum amount of B3 was belong to steam flacked wheat (0. 5), pelleted barley (0. 5) and pelleted corn (0.3) respectively. The minimum amount of C part in crude protein belong to milled wheat (0.01), milled barley (0.07) and dried roll corn (0.02) percentage of dry matter respectively. In general, considering the cost and the required equipments, in processing of wheat, barley and corn, steam flaking, pelleting and milling methods are proposed respectively.
