The xanthophyll esters, that are normally recovered from plant sources such as the marigold plant, Tagetes erecta, are selectively saponified. The neutralized, selectively saponified material, when incorporated into an inert carrier, provides a stable xanthophyll product having a pH above about 8. Such products have improved stabilities as compared to the original esters or to fully saponified esters. |
