Preparation method of water-soluble immature bitter orange extract with bitterness removed

Abstract

The invention discloses a preparation method of a water-soluble immature bitter orange extract with bitterness removed. The method comprises steps as follows: step one, selecting an immature bitter orange extract containing 10% of synephrine, dissolving the immature bitter orange extract with 10 times of water, heating the solution to the temperature of 70 DEG C to prepare an immature bitter orange extract aqueous solution; step two, adding 1% of an aqueous solution of 5% of a clarifying agent ZTC-B of dry powder to the immature bitter orange extract aqueous solution in step one, performing stirring and heating for 10 min, and adding 1% of an aqueous solution of 5% of a clarifying agent ZTC-A of dry powder, and performing stirring and heating for 10 min; step three, subjecting a filtered filtrate to macroporous adsorption resin HPD-600 to adsorb flavonoid bitterness ingredients of the immature bitter orange extract until the effluent is free of bitterness to obtain the immature bitter orange extract with bitterness removed; step four, performing water elution on the resin column to obtain a water solution; step five, merging, concentrating and drying the water solution and the effluent to obtain the water-soluble immature bitter orange extract with bitterness removed finally. The method has very good technical effects.

Description

technical field [0001] The invention belongs to a method for preparing a water-soluble debittering citrus aurantium extract, specifically a method containing 10% synephrine water-soluble debittering citrus aurantium extract. [0002] Background technique [0003] Citrus aurantium, the name of traditional Chinese medicine; it belongs to the dried young fruit of Rutaceae plant sour orange and its cultivars or sweet orange. Lime, small tree of Rutaceae, citrus, with dense branches and leaves, many thorns, the thorns of the elongated branches are up to 8 cm. The leaf color is dark green, and the texture is quite thick. It is mainly produced in Sichuan, Jiangxi, Fujian, Jiangsu and other places. Pick or collect the self-falling fruit between May and June, cut it into two halves from the middle, sun-dry or low-temperature drying, and the smaller ones are directly sun-dried or low-temperature drying. When used, wash, suffocate, cut into thin slices, and dry. Used raw or fried w...
