| titleOfInvention | A kind of thick extracting method of theabrownin and smart extracting method |
| abstract | The present invention relates to a kind of thick extracting method and smart extracting method of theabrownin, it is mainly used in the deep processing field of tealeaves. Slightly carrying in process of theabrownin, first polyphenol oxidase enzyme aqueous solution is sprayed onto on tealeaves, makes tealeaves produce enzymatic oxidation reaction, and then cure processing at 150 DEG C～160 DEG C, make tealeaves generation chemical oxidation and cracking, last water and ethanol carry out the extraction of theabrownin. Carry in process in the essence of theabrownin, taking theabrownin of Pu'er tea as template molecule, be prepared into theabrownin molecularly imprinted polymer; Then by water-soluble the crude extract of theabrownin, add theabrownin molecularly imprinted polymer, stirring and adsorbing, is dried through filtration, wash-out, spraying, obtains theabrownin sterling. The present invention has overcome limitation that raw material selects and the deficiency of existing extraction industry reagent contamination, provide a kind of improve theabrownin content in tealeaves make it the scope of application wider and finished product purity is higher, without the residual theabrownin preparation method of industrial reagent. |
