| titleOfInvention | Xanthophyll extraction process |
| abstract | The invention provides a technology for extracting lutein, which comprises the following steps: adding organic extraction solvent into crushed marigold flowers, putting the mixture in an ultrasonic extracting kettle for ultrasonic extraction, filtering extracting solution to recycle the filtrate containing lutein ester; adding 2 times filtrate volume of aqueous alkali into the filtrate obtained in the last step, and carrying out saponification reaction on the lutein ester in the filtrate at a temperature of between 50 and 70 DEG C; washing the reaction product subjected to the saponification reaction by deionized water until the lutein is crystallized, and carrying out centrifugalization on the solvent containing lutein crystal to obtain a crude product of the lutein crystal; recrystalizing the crude product of the lutein crystal; washing and drying the lutein crystal obtained by recrystalization to obtain a finished product of the lutein crystal. The method for extracting the lutein by ultrasonic can accelerate the lutein to enter the solvent by strong vibration generated by ultrasonic, high acceleration, strong cavitation effect, stirring action and the like, thereby increasing the extraction yield of effective components, and shortening time of extraction. |
