Abstract

La presente invención se refiere a un proceso para la eliminación de trazas de contaminantes, específicamente fosfolípidos y iones metálicos asociados, de aceites de glicéridos mediante la adsorción de dichas trazas de contaminantes en sílice amorfo, dicho proceso está caracterizado porque comprende los siguientes pasos: a) la selección de un aceite de glicérido con un contenido de fósforo en exceso de aproximadamente 1.0 ppm; b) la selección de un adsorbente que comprende un hidrogel de sílice amorfo parcialmente seco que tenga un contenido de humedad de, cuando menos, aproximadamente 25 por ciento por peso y un diámetro medio de poros de aproximadamente 60 Angstroms o menos; c) efectuar el contacto del aceite de glicérido del paso (a) con el adsorbente del paso (b); d) permitir que las trazas de contaminantes se adsorban en el adsorbente; e) efectuar la separación del aceite de glicérido agotado de fosfolípidos y de iones metálicos resultante del adsorbente.The present invention refers to a process for the removal of traces of contaminants, specifically phospholipids and associated metal ions, from glyceride oils by adsorbing said traces of contaminants on amorphous silica, said process is characterized in that it comprises the following steps: a ) selection of a glyceride oil with a phosphorus content in excess of about 1.0 ppm; b) selecting an adsorbent comprising a partially dry amorphous silica hydrogel having a moisture content of at least about 25 weight percent and an average pore diameter of about 60 Angstroms or less; c) contacting the glyceride oil from step (a) with the adsorbent from step (b); d) allowing traces of contaminants to adsorb on the adsorbent; e) carry out the separation of the glyceride oil depleted from phospholipids and metal ions resulting from the adsorbent.
