| Abstract: | The paper provided a process for preparing zeaxanthin from lutein by basis catalysis.The process also included optimization of technic parameters.The results showed that the optimal reaction condition was as follows:using 1,2-propanediol as solvent,reaction time for 168 h and reaction temperature at 110 ℃,under inert atmosphere.The ratio of 1,2-propanediol to lutein was 20,and the ratio of potassium hydroxide to lutein was 6.According to HPLC analysis,the yield of zeaxanthin can reach 93% under the optimal condition. |
