Abstract
The present disclosure provides a preparation method of carotenoid agent. The preparation method provided in present disclosure includes: mixing a suspended organic dispersion phase of a carotenoid crystal with a first organic solvent in a spiral coil of a coil heat exchanger to form a mixed solution, with the carotenoid crystal in the suspended organic phase of the carotenoid crystal being dissolved in the first organic solvent to obtain an oil phase matrix of the carotenoid dissolution solution, wherein the temperature inside the spiral coil is from 50° C. to 70° C. In the present disclosure, the carotenoid crystal is dissolved in the first organic solvent at 50° C. to 70° C., effectively avoiding the drawbacks of isomerization reaction of the carotenoid agent when it is dissolved in traditional preparation methods.
