| Abstract | ||||
| The present work was conducted to study the effect of different treatments in barley grain before milling (drain in water for 8,16,24 and 32 hours ,hot air in oven for 1/2 ,1 ,11/2 and 2hours , drain in hot water for 1/2 ,1 ,11/2 and 2 hours, and drain in boiling Ca(OH)2 solution(1%) for 1/2 and one hours) . Results showed that, drain barley grains with water for 24 or 32 hours increased the extraction rate comparing with different treatments in addition to control (without any treatments) which were ( 87.60 and 88.50% ) respectively. Also, for chemical composition of barley flour with different treatments ,showed that barley grains drain in water for 24 or 32 hours contained higher protein, fat ,crude fiber, ash and β-glucan comparing with all treatments in addition to control (without any treatments) which were (12 .59 and12.72 ,3.0 and 3.3 , 4.69 and 4.74 ,2.46 and 2.49 ,4.73 and4.78 g/100g on dry Wt)respectively. Also, contained the highest amount of minerals (Zn, Ca, Fe, Mg, Mn, Na and k). From the results obtained , it could concluded that , drain barley grains with water for 24 or 32 hours showed better extraction rat, chemical composition and mineral content. | ||||
