[Objective]To investigate the production process of saponified lutein. [Method]The effects of material-liquid ratio,temperature,concentration of potassium hydroxide in ethanol and reaction time on the saponification rate were studied through single-factor and orthogonal experimental designs. [Result]The results show that concentration of potassium hydroxide and reaction time have a remarkable effects on the saponification rate. The optimum conditions were as follows:material-liquid ratio of 1:0.5,temperatur...
