Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA PRODUCCION INDUSTRIAL EN UN MEDIO ACUOSO DE UN EXCIPIENTE DE LIBERACION LENTA QUE CONSISTE BASICAMENTE EN LA AMILOSIS RETICULADA QUE TIENE PROPIEDADES DE LIBERACION CONTROLADA, PARA SU USO EN LA PREPARACION DE COMPRIMIDOS O DE GRANULADOS. SE SOMETE PRIMERO UN ALMIDON QUE CONTIENE UNA CANTIDAD ELEVADA DE AMILOSIS (ALMIDON CON ALTO CONTENIDO DE AMILOSIS) A UNA GELIFICACION. SE SOMETE LUEGO ESTE ALMIDON GELIFICADO A UNA RETICULACION MEDIANTE 1 A 5 GR DE AGENTE DE RETICULACION PARA 100 GR DE ALMIDON GELIFICADO DE BASE SECA EN UN MEDIO ALCALINO, LO QUE PERMITE OBTENER UN MEDIO REACCIONAL QUE CONTIENE UN PRODUCTO REACCIONAL QUE CONSISTE EN UNA PASTA LIQUIDA DE ALMIDON RETICULADO DE ALTO CONTENIDO DE AMILOSIS. SE NEUTRALIZA EL MEDIO REACCIONAL OBTENIDO, Y ELLO PERMITE LA OBTENCION DE PRODUCTOS SECUNDARIOS CONSTITUIDOS BASICAMENTE POR SALES, QUE SE QUITAN DEL MEDIO REACCIONAL. SE SOMETE LUEGO LA PASTA LIQUIDA DE ALMIDON RETICULADO RECUPERADA A UN TRATAMIENTO TERMICO A UNA TEMPERATURA DE, POR LO MENOS, 60 GRADOS C Y SE SECA EL PRODUCTO TRATADO TERMICAMENTE PARA OBTENER EL EXCIPIENTE DESEADO CON LIBERACION LENTA. ESTE PROCESO ES ECONOMICO Y TIENE VENTAJAS DESDE EL PUNTO DE VISTA INDUSTRIAL, PUESTO QUE SE EJECUTA EN UN MEDIO ACUOSO.
