The present invention provides a method for preparing a licorice powder comprising the steps of: 1) adjusting moisture of licorice powder; 2) To the water-adjusted licorice powder of the above step 1) was added Aspergillus oryzae or Aspergillus luchuensis ; 3) fermenting the licorice powder inoculated with Hwanggi gum or white germ in step 2) to obtain a licorice fermented product; And 4) extracting the licorice fermented product of step 3) with an extraction solvent to obtain a licorice fermented extract. The present invention also provides a method for producing licorice fermented extract having an increased content of liquiritigenin, , It is possible to obtain a licorice fermented extract containing a high content of liquiritigenin and a microorganism having a high activity of β-glucosidase is applied. Therefore, it is environmentally friendly and can be used as a simple and inexpensive method of controlling the fermentation conditions of licorice The content of quiritidine can be increased. In addition, the licorice fermented extract produced by the production method of the present invention contains a high content of liquiritigenin and is excellent in antioxidative activity and can be widely used in foods, medicines, health functional foods, cosmetics, etc., Zero can also be used. |
