| titleOfInvention | A kind of industrial production process of lutein crystal |
| abstract | The invention discloses a kind of industrial production process of lutein crystal, include the following steps：（1）The preparation of lutein saponification liquor：Lutein extract is dissolved by heating, lye and alcoholic solution saponification are added in the lutein extract of dissolution, obtains lutein saponification liquor；（2）The preparation of lutein crystal：Lutein saponification liquor alcohol solution is eluted in the equipment containing liquid dispersion and carries out, and forms lutein crystal after lutein saponification liquor is washed；（3）The preparation of lutein:Lutein product is obtained after lutein crystal is dry.This method transmission speed is fast, the residence time is short, it not only can continuously prepare lutein, and washing is avoided to generate the adverse effect that lutein is carried in emulsification secretly, improve lutein yield and crystalline content, without the secondarily purified high purity lutein product that mass percentage >=93% can be obtained, lutein yield >=92%. |
