METHOD FOR EXTRACTION AND PURIFICATION OF FLAVONOID AND PECTIN FROM CITRUS MEAL BY CONTINUOUS PROCESS

摘要

PURPOSE: Provided is a method for extracting and purifying flavonoid and pectin from citrus meal by a continuous process comprising extracting grinding, drying, hydrolyzing, washing and extracting processes. CONSTITUTION: The method for extracting and purifying flavonoid and pectin from citrus meal comprises the steps of: extracting flavonoid from a mixture of citrus meal and methanol in a ratio of 1:10, at 90 to 100deg.C for 6hr; grinding and drying residues; adding 10% hydrochloric acid and water, in a ratio of 0.47g and 47.14g, to 5g of powder, and reacting for 40min and washing them; adding 1.8 times warm water of 80deg.C or more and 0.02 to 0.03 times 10% hydrochloric acid to the washed residues and reacting them at 80 to 100deg.C for 30 to 120min to obtain an extract; and filtering and freeze drying the extract.
