Problems solved by technology

Compared with water extraction, the organic solvent extraction method consumes less energy, has a higher extraction rate, and can effectively reduce the denaturation of polyphenols during the extraction process, but the residual organic solvent and the pressure on the environment have always restricted this method. widespread application of the law
[0005] At present, there are not many published data on the separation and purification of cinnamon polyphenols, and there is no data suitable for industrial production.

Abstract

The invention discloses a method for preparing polyphenol by using cinnamon residues. The method comprises the following steps: (1) mixing cinnamon residue dry powder and ethanol, stirring, extracting, standing, filtering, extracting, combining extracting liquid, evaporating and drying; (2) mixing the product obtained in the step (1) and petroleum ether, extracting, recovering petroleum ether from supernatant liquid, adding the extractant into ethyl acetate, extracting, combining the supernatant liquid, evaporating the ethyl acetate and performing freeze drying after solid is frozen to obtain a cinnamon residue polyphenol crude extract. The cinnamon residue polyphenol extract is extracted from the cinnamon residues, and the preparation method is simple, high in extraction efficiency, low in production cost, high in safety and suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of polyphenol preparation, and in particular relates to a method for preparing polyphenol from cinnamon residue. Background technique [0002] Polyphenols refer to plant phenols with multiple phenolic hydroxyl groups in the molecule. Cinnamon pomace fruit contains a high content of natural polyphenolic compounds. Plant polyphenolic substances have strong antioxidant capacity, which is 20 times that of vitamin C at the same dose, so it can effectively remove toxins from the human body. Oxygen free radicals, thereby reducing the damage of oxygen free radicals to normal cells, and playing a protective role. At the same time, polyphenolic compounds can also prevent the formation and accumulation of potential carcinogenic substances in the human body, improve metabolism, and have significant anti-cancer effects. In addition, some polyphenols with special structure in cinnamon pomace fruit have some special effe...
