Abstract
Se describe un procedimiento de ixomerización de luteina a zeaxantina que incluye una etapa de saponificación o tratamiento con álcali de un extracto vegetal que contiene luteína, seguida de una etapa de calentamiento bajo condiciones controladas se lleva a cabo en presencia de un agente tensoactivo que tiene un balance hidrofílico-lipofilico de 1 a 40 como catalizador para la reacción de isomerización de Luteína a Zexantina a una temperatura de 70 a 140 C, obteniéndose un producto de reacción con altas concentraciones de zeaxantina de hasta 80% con respecto a los carotenoides totales.A process of ixomerization of lutein to zeaxanthin is described which includes a step of saponification or alkali treatment of a plant extract containing lutein, followed by a step of heating under controlled conditions is carried out in the presence of a surfactant having a hydrophilic-lipophilic balance from 1 to 40 as a catalyst for the reaction of Lutein to Zexanthin isomerization at a temperature of 70 to 140 C, obtaining a reaction product with high concentrations of zeaxanthin up to 80% with respect to the total carotenoids.
