Abstract

The invention discloses a method for saponifying lutein grease, which comprises the following steps of: mixing the lutein grease, water and a strong base, and adding a cationic surfactant before or during saponification reaction. Therefore, an anionic surfactant palmitate generated in the saponification reaction process is unexpectedly deactivated, reaction solution does not get viscous and still has relatively higher liquidity, the saponification reaction can be more quickly and completely performed, and ordinarily can be finished after 7 to 8 hours, and the extent of the reaction is as high as 85 to 99 percent. In the method, by controlling the amount of the cationic surfactant, the reaction solution obtained by the reaction has a certain emulsification effect, can be directly sprayed and dried, effectively reduces energy consumption and saves the production cost.

Description

technical field [0001] The invention relates to a saponification method of lutein oil. Background technique [0002] Lutein is a carotenoid, which is widely found in vegetables, flowers, fruits and other plants, especially in marigolds. Most of the lutein sold in the market is saponified after extraction from marigolds. Lutein in marigold mainly exists in the form of its palmitic acid diester. [0003] There are many ways to saponify lutein oil. The traditional saponification method is to heat lutein oil in alkaline water to 60-80°C, and saponify to obtain lutein monomers (lutein and a small amount of zeaxanthin). Since the palmitate generated by this saponification reaction is an anionic surfactant, it will continuously emulsify the reaction solution, making the reaction solution become very viscous, which directly affects the speed of the saponification reaction, resulting in prolonged saponification time and increased impurities. And the saponification is not complete....
