Pearling, an important primary process on food barley utilization, refers to the gradual removal of grain tissues starting from the outer grain tissues/layers, bran, and germ. The removal of barley bran through pearling yields a bright white kernel that is ideal for various food applications. The removed grain layers are usually sold as feed. However, its use for producing various innovative food products such as high-fiber functional pasta. Here we investigated composition of pearled barley. Barley grains from two hull-less varieties, Saechalssal and Hinchalssal, were pearled to various degrees(10-60%). The composition (protein, β-glucan, fat, ash, total phenol and proanthocyanidin) of pearled barley fractions flour(PF) was determined. Protein, fat, ash, total phenol and proanthocyanidin content was decreased in PF according to increasing pearling degree. Hunter L value and whiteness was increased. β-glucan content also was increased from 3.35, 2.73% to 8.9, 9.3% in Sachalssal and Hinchlssal individually. PF of Sachalssal and Hinchalssal showed different content in all components. Protein content was the highest in 90～80% flour fraction. Total phenol, proanthocyanidin and crude fat content was the highest in outer grain layer, bran(100～90% fraction) than other fractions.
