Abstract

PROCEDIMIENTO PARA PREPARAR FIBRAS DE COLAGENO RECONSTITUIDO MACROMOLECULAR. CONSISTE EN TRATAR COLAGENO INSOLUBLE NATURAL CON UNA SOLUCION ACUOSA DE SULFATO DE SODIO DE CONCENTRACION APROXIMADA A UNO MOLAR E HIDROXIDO DE SODIO DE CONCENTRACION APROXIMADA A DOS MOLAR. SE PROCEDE DE ESTA FORMA DURANTE CUARENTA Y OCHO HORAS PARA SAPONIFICAR LAS GRASAS SUSPENDIDAS EN EL COLAGENO NATURAL E HINCHAR LAS FIBRAS DE DICHO COLAGENO. LIBRE DE GRASA, SE TRATA CON SULFATO DE METAL ALCALINO DURANTE CUATRO HORAS; DE ESTA FORMA SE ESTABILIZAN LAS UNIONES ENTRE FIBRAS. SE DISUELVE EL COLAGENO EN SOLUCION DE ACIDO ASORBICO DE PH CUATRO, SE CONGELA DICHA SOLUCION A UNA VELOCIDAD DE REDUCCION DE LA TEMPERATURA DE -18G A -14GC POR HORA Y SE SECA DURANTE DOCE HORAS. DE APLICACION EN ALIMENTACION, COSMETICA Y FARMACIA.
