Method for extracting hesperidin from young citrus fruits based on puffing treatment

Abstract

The invention discloses a method for extracting hesperidin from young citrus fruits based on a puffing treatment. The method comprises the following steps: (1) carrying out a puffing treatment; (2) dynamically removing impurities; (3) dynamically washing; (4) dynamically extracting; (5) performing acid regulation and crystallization; (6) crystallizing and filtering; and (7) drying. Hesperidin is extracted by using a puffing technology, an organic solvent such as ethanol is not used; after the puffing treatment, the citrus impurity removal-washing-extraction efficiency is greatly improved, thewater consumption is reduced, and the sewage discharge amount is reduced. Cooking is not needed, energy consumption is reduced, the method is green and environmentally friendly, and the process is simplified. Multiple hesperidin extraction pretreatment technologies are integrated and optimized; the impurity removal and extraction time is shortened from original 48 hours to 12-13 hours while the product quality and the recovery rate are guaranteed, an innovative way is provided for hesperidin extraction in a factory, the extraction process time is greatly shortened, and the productivity is doubled under the condition that workshops and equipment are not increased. In addition, the process is simple, the operability is high and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for extracting hesperidin, in particular to a method for extracting hesperidin from young citrus fruits based on puffing treatment. Background technique [0002] Hesperidin (hesperidin) is generally extracted from the physiological fruit drop during the growth of citrus. In view of the seasonality of citrus growth, fresh fruits are generally collected and stored in the sun. It is mainly distributed in provinces such as Huguang, Shaanxi, Sichuan and Guizhou in my country, and the quality is better in Hunan. Hesperidin is a dihydroflavonoid drug. Pharmacological action: It is clinically used in combination with vitamin C to treat various hemorrhagic diseases caused by increased vascular fragility. Hesperidin can excite frog hearts in vitro and in situ. Intravenous injection of hesperidin can enhance the cardiac contractility of the rabbit in situ, but has little effect on the heart rate, and increases the cardiac outp...

Problems solved by technology

In this method, raw materials are refined with alkaline water, cleaned with alkaline water and weakly alkaline, and combined with subsequent plate and frame separation, ceramic membrane filtration and acid precipitation steam removal. The operation is complicated, and the amount of sewage during its removal and extraction Large, high energy consumption, high equipment requirements, and high cost

[0006] At present, the large-scale production of hesperidin has problems such as high difficulty, low yield, long cycle, difficult industrialization or very thin profits after industrialization.
