Abstract

The invention discloses a method of extracting black chokeberry fruit polyphenols and black chokeberry fruit polyphenol extract acquired via the method. The method comprises the steps of 1) soaking black chokeberry fruits, carrying out extracting for 1-4 h, and filtering to obtain filtrate; 3) adding an organic additive, stirring for 5-15 min, and filtering to obtain a clear liquid; 4) discoloring, purifying, and drying to obtain the black chokeberry fruit polyphenol extract. The black chokeberry fruits are soaked with hot water, so that phenol oxidase is inactivated, and phenol oxidation is prevented; black chokeberry alpha hydroxy acid in cell walls can be dissolved under the action of sodium carbonate and a surfactant, polyphenols can be released and are less oxidized, and solubility ofthe polyphenols can be improved; the system is stable, mobility is good, the yield and purity are increased, the flow path is short, biological enzymes are not required, adjusting pH is not required,the cost is low, and the method is easy to industrialize.

Description

technical field [0001] The invention belongs to the technical field of extracting active substances of Aronia berry, in particular to a method for extracting Aronia berry polyphenols and the obtained berry polyphenol extract. Background technique [0002] In 2018, Aronia melanocarpa (Michx.) Elliott was identified as a new food raw material by the National Health Commission. It is a shrub belonging to the family Rosaceae and can reach a height of 3m. The root is brownish yellow, with a potential root system, and the root does not have the ability to branch. Young branches glabrous. Bark reddish brown or taupe, with obvious round lenticels, dark green leaves, single leaves, alternate; reticulated veins, leaves oval or elliptical to elliptical-oblanceolate, sharp or blunt; Pear fruit, purple-black peel, dark red flesh, kidney-shaped seeds, brown, compound corymbs, fluffy on inflorescence stalk, small flowers, anthers are drug-backed, pink; petals are white, sepals, detached ...
