| titleOfInvention | Method for preparing quercetin or isoquecitrine using beta-glucosidase |
| abstract | The present invention utilizes beta-glucosidase (EC 3.2.1.21) derived from Aspergillus niger (Accession No .: KCTC 6906) to quercetin glycosides to quercetin. The present invention relates to a method for preparing isoquercitrin or isoquercitrin, and the method for preparing quercetin or isoquercitrin according to the present invention may be achieved by using conventional chemical synthesis techniques and enzymes. Compared to the method of bioconversion to quercetin or isoquercitrin or to increasing the content of flavonoids such as quercetin using infrared light, the process is simple and easy to purchase on the market. Using onion as a raw material and enzymatically reacting quercetin glycosides contained in onions economically, quercetin or isoquecitrine (isoque) In addition to the production of rcitrins, the use of selective site specificity of the beta-glucosidase (β 3.2.1.21) enzyme facilitates mass production in a short time and with high efficiency, therefore, quercetin or isoque Citrine (isoquercitrin) can be usefully used in pharmaceutical compositions, foods, flavors, beverages, herbal preparations, dietary supplements. |
