Abstract

The invention relates to a method for extracting cyaniding and belongs to the technical field of extracting natural medicaments. The method adopts the process of ultrasonic-assisted enzyme method extraction, flocculation, ultrafiltration, macroporous resin adsorption, nanofiltration condensation, spray drying and high-purity cyaniding. Compared with the traditional processes, the method has the advantages of overcoming the defects in the traditional processes, effectively improving the yield and the quality of the product, greatly lowering the consumption and the loss of the organic solvents,reducing energy consumption, lowering production cost, having practicability and progress and reaching the domestic leading level.

Description

technical field [0001] The invention relates to an extraction method of anthocyanins, belonging to the technical field of extraction of natural medicines. Background technique [0002] Anthocyanin is a water-soluble plant pigment, and its chemical essence is polyphenols. Since the discovery of anthocyanin’s ability to scavenge free radicals in the human body, it has been recognized by more and more people. At present, anthocyanins are widely used in medicine, health products, cosmetics and other fields. Anthocyanins are expensive, and their prices increase exponentially with the increase in purity, so developing anthocyanins with high purity has great market value. The traditional method of extracting anthocyanins not only has low extraction rate and low purity, but also cannot remove sugar and protein, so its use is also limited and can only be used as a raw material for fruit juice drinks. The invention patent with the publication number of 101153031A discloses a method ...
