Problems solved by technology

The advantage of the organic solvent extraction method is that it is easy to operate and does not require complicated equipment; the disadvantage is that the consumption of organic solvents is high, time-consuming, and heating during extraction will cause oxidative degradation of anthocyanins
The microwave method and the ultrasonic method cannot carry out large-scale industrial production due to the limit value of the equipment.
Supercritical extraction can be industrialized at present, but due to the particularity of this technology, the cost of anthocyanins produced by this technology is high, and this product cannot be promoted to ordinary consumers
[0005] At present, the commonly used purification method is mainly carried out by using macroporous adsorption resin. The advantage of macroporous adsorption resin is that it has a large adsorption capacity, can be used repeatedly, and can save costs at a certain cost; the disadvantage is that there are more impurities adsorbed. The product purity improvement is not very significant

Abstract

The invention belongs to the field of natural organic chemistry and relates to extraction and separation method of anthocyanidin from mulberry. According to the method, tea polyphenol which is used as an antioxidant is extracted under the alkaline condition; impurities are removed by the use of a flocculant under the acidic condition; and an extracting solution is purified by the use of cation exchange resin so as to obtain a high-purity anthocyanidin product. The invention has advantages as follows: 1, as water is used as an extraction solvent under the alkaline condition, production cost is greatly reduced by the method in comparison with a traditional extraction method by the use of ethanol; 2, by adding a natural antioxidant in the extraction process, loss of anthocyanidin can be effectively reduced; 3, impurities in the extracting solution are deposited by the use of a flocculant; and 4, the extracting solution is purified by the use of cation exchange resin so as to remarkably raise purity of the anthocyanidin product. The prepared anthocyanidin can be widely applied in fields of health food and cosmetic, etc.

Description

technical field [0001] The invention belongs to the field of natural organic chemistry and relates to an industrialized method for preparing anthocyanins from mulberries. Background technique [0002] Anthocyanin is a water-soluble pigment that can change color with the acidity and alkalinity of the cell fluid. The cell fluid is acidic and reddish, and the cytosol is alkaline and blue. Anthocyanin is one of the main pigments that make up the color of petals and fruits. Anthocyanins are secondary metabolites of plants, which play an important role in physiology. Anthocyanins are pure natural anti-aging nutritional supplements. Studies have proved that they are the most effective plant antioxidants found by humans today. Its antioxidant properties Fifty times higher than vitamin E and twenty times higher than vitamin C. Its bioavailability to the human body is 100%, and it can be detected in the blood 20 minutes after taking it. It has a significant effect on enhancing visio...
