Abstract

UN METODO PARA SEPARAR ALGAS MARINAS QUE CONTIENEN KAPPA-CARRAGENANO RESPECTO DE ALGAS MARINAS QUE CONTIENEN LAMBDA-CARRAGENANO, EN EL QUE SE SOMETE UNA MEZCLA DE DICHAS PLANTAS A UNA HIDRATACION PREFERENCIAL DE LAS PLANTAS LAMBDA SIN DISOLUCION SUSTANCIAL DEL CARRAGENANO, PREFERIBLEMENTE MANTENIENDO LA MEZCLA EN CONTACTO CON UNA SOLUCION ACUOSA QUE ESTA A UN PH SUPERIOR A APROXIMADAMENTE 10 Y QUE CONTIENE UN CATION SELECCIONADO DEL GRUPO CONSISTENTE EN AMONIO, POTASIO, RUBIDIO, CESIO, CALCIO, BARIO, ESTRONCIO Y MAGNESIO, Y LAS PLANTAS LAMBDA SE SEPARAN DE LA PLANTAS KAPPA POR SELECCION BASADA EN EL CONTENIDO DE AGUA O EN PROPIEDADES RELACIONADAS CON EL CONTENIDO DE AGUA O DEPENDIENTES DEL MISMO. ESTE METODO ES ESPECIALMENTE UTIL PARA PROPORCIONAR CARRAGENANO EN SU FORMA KAPPA O LAMBDA SUSTANCIALMENTE PURA.
