| Abstract: | The β-glucan was extracted from barley in Tibet by the procαess of comminution, hydrolysis of starch, immersion in alkali soluble and precipitation by ethanol, the results show that the optimum conditions were 60 hole barley powder, ratio of barley powder and water 1:5, addition of α-amylase 400 U/mL, time for hydrolysis 1 h, temperature and pH for extraction 80OC and 8.5, and the addition of ethanol 3 fold for concentration of extraction. Thus, the percentage extraction of β-glucan from barley was 1.09% and 18% glucose was obtained. |
