| Abstract: | Using dried lotus seed as material and ethanol as the solvent,based on the single factor tests,the optimum extraction technology was determined through orthogonal experiments: ethanol concentration was 90%,ratio of material to liquid was 1∶10,the power of the microwave radiation was 300 W,extraction time was 35 s,microwave extraction was three times.Under such conditions,the extraction rate of lotus seed was 7.74 mg·g-1. |
