| Abstract: | Objective To optimize the extraction technology of amylase in roasted malt by orthogonal test.Methods The orthogonal design test L9(34) was employed to investigate the effect of extraction time,extraction temperature,solvent consumption,extraction time on the activity of amylase in roasted malt.The content of amylase was determined by iodine volume method.Results The optimum extraction condition was to add 25 times volume of distilled water and to extract 3 times for 60 min each time at 20 ℃.Conclusion This extraction method is valid and feasible for extracting amylase from the roasted malt. |
