摘要 A method of isomerizing lutein to yield a mixture of epimers of zeaxanthin includes the following steps: mixing a lutein-containing extract in a glycol solution to obtain a mixture, treating the mixture with alkali to obtain an alkali-containing mixture, reacting the alkali-containing mixture in the presence of heat for a duration consistent with achieving a desired level of isomerization of lutein to zeaxanthin.
