The present disclosure relates generally to a process for obtaining a naturally derived composition rich in polymethoxylated flavonoids (PMFs). In some embodiments, the process results in a composition in which PMFs make up at least 90% by weight of the flavonoid content in the composition, based on the total weight of flavonoids in the composition. In certain aspects, the disclosure provides compositions resulting from the purification process and the use of such compositions to reduce bitterness, astringency, or sourness, or to enhance 0 sweetness or mouthfeel of an ingestible composition, such as a flavored food or beverage product. In some embodiments, the disclosure provides uses of the resulting composition to reduce the unpleasant taste of limonin, nomilin, or, one or more of which can be present at elevated levels in certain citrus products. naringin

The present invention relates to the field of dihydromyricetin extraction and purification, and in particular to a dihydromyricetin extraction and purification process. Technical problem: the dihydromyricetin extraction and purification process aims to resolve the technical problems of increased cost of subsequent impurity removing and safety risks in high-temperature centrifugation in the prior art. Technical solution: a dihydromyricetin extraction and purification process: step 1: weighing a raw material, adding an extraction solvent in an amount 5 times that of the raw material to perform reflux extraction, concentrating the filtrate to an extract, and recovering acetone; step 2: resting for crystallization for 24 hours; step 3: performing suction filtration to obtain light-green sediment underneath, and dry the sediment; step 4: adding 5%-10% activated carbon for decolorization and impurity removing; step 5: performing suction filtration; step 6: drying to obtain white powder of dihydromyricetin; and step 7: detecting a content with HPLC.
