| titleOfInvention | Method for preparing lutein by utilizing marigold ointment |
| abstract | The invention provides a method for preparing lutein by using marigold ointment, which comprises the following steps: adding an organic extractant to the marigold ointment, and processing under ultrasonic conditions to obtain an extract; adding a phase transfer catalyst, Mix alcohol and alkali solution, heat and stir to carry out saponification reaction to obtain saponification solution; add saponification solution to high-speed disperser for dispersion, then add surface modifier under heating and stirring conditions for modification treatment to obtain modified solution ; Separate and purify the modified solution to obtain lutein. In the invention, the marigold ointment is pretreated under ultrasonic conditions to be fully dissolved, and the phase transfer catalyst is added to the extract, which can effectively increase the compatibility of the alkali solution and the ester in the extract, so as to improve the reaction activity and shorten the reaction time. Moreover, by adding a surface modifier, the water solubility of lutein can be effectively improved, which is beneficial to the subsequent separation and purification steps, so as to reduce the use of a large amount of organic solvents for extraction and other processes. |
