GRAIN FRACTIONATION |
摘要 |
A method is described for obtaining dextrin-enriched and beta-glucan-enriche d fractions from barley flour. In particular, barley flour is mixed or ground in about 6 0% ethanol at boiling temperature, then dextrinized by addition of thermostable alpha- amylase and reluxing at boiling temperature. The dextrinized mixture is filtered such th at beta-glucan is retained on the filter and dextrin is in the filtrate. To increase the purity of the beta- glucan to at least >45% db and to increase the dextrin yield, the beta-gl ucan residue is resuspended in 60% ethanol and treated with alpha amylase and filtered as previously noted. After alcohol is evaporated from the combined filtrates, the dextrin is spray dried into a powder.
