영문 초록

These experiments were conducted to investigate correlation of soluble fractional β-glucan compositions to chemical ingredients in pearled kernels among barley varieties, which included 12 high β-glucan lines of introduced covered barleys based on “Studies on selection of dietary fiber resources 1” and 10 domestic recommended varieties. The β-glucan content of the high β-glucan lines was average 6.07% which was similar level of waxy type, the highest β-glucan content according to kernel types. In quantitative analysis of soluble fractional β-glucan content of barleys, it was showed that alkaline soluble fractions(1N NaOH+24% NaOH) were 70~80%. Chal-bori, which had the highest alkaline viscosity, showed the highest water soluble fractional β-glucan and also the highest water soluble pentosan content. Covered type varieties were higher than naked type varieties in ash content. Alkaline visocosities of barley flour were negatively correlated with amylose content and positively correlated with water soluble β-glucan and pentosans in pearled barley kernels.
