Abstract

SE OBTIENE ACIDO CITRICO Y/O SUS SALES A PARTIR DE UNA MATERIA PRIMA QUE CONTIENE HIDRATOS DE CARBONO. UNA SOLUCION ACUOSA DE LA MATERIA PRIMA SE TRANSFORMA MEDIANTE FERMENTACION EN UNA PRIMERA SOLUCION QUE CONTIENE ACIDO CITRICO, Y SE RECUPERA A PARTIR DE LA PRIMERA SOLUCION MEDIANTE UNA SEPARACION CELULAR UNA SEGUNDA SOLUCION QUE CONTIENE ACIDO CITRICO. LA SEGUNDA SOLUCION SE SOMETE A TEMPERATURAS DE 2 A 70° C A UNA PRECIPITACION DE PROTEINAS, Y SE SEPARAN LAS PROTEINAS MEDIANTE FILTRACION. DE LA FILTRACION SE OBTIENE UNA TERCERA SOLUCION QUE CONTIENE ACIDO CITRICO Y SE LLEVA ESTA A TRAVES DE UN PRIMER INTERCAMBIADOR ANIONICO. LA SOLUCION QUE CONTIENE ACIDO CITRICO PROCEDENTE DEL PRIMER INTERCAMBIADOR ANIONICO SE LLEVA A UN SEGUNDO INTERCAMBIADOR ANIONICO, EL CUAL SE CARGA DE MANERA SELECTIVA CON ACIDO CITRICO. EL SEGUNDO INTERCAMBIADOR ANIONICO CARGADO CON ACIDO CITRICO SE ELUYE CON UNA SOLUCION DE HIDROXIDO O DE AGUA, Y SE OBTIENE ASI UNA CUARTA SOLUCION, EN LA CUAL ESTA DISUELTO EL CITRATO O ACIDO CITRICO. DE LA CUARTA SOLUCION SE QUITA EL AGUA POR LO MENOS PARCIALMENTE.
