Abstract

LA INVENCION SE REFIERE A UN METODO PARA COMPROBAR CUANTITATIVAMENTE LA CANTIDAD DE CUALQUIER AGUA EXTRAÑA CONTENIDA EN UNA MUESTRA DE LECHE, EL METODO COMPRENDE LOS PASOS DE A) REALIZAR UNA DETERMINACION DE LA ATENUACION DE INFRARROJOS (IR) DE LA MUESTRA EN AL MENOS UNA BANDA DE ONDAS, B) COMPROBAR CUANTITATIVAMENTE LA CANTIDAD DE AGUA EXTRAÑA EN LA MUESTRA SOBRE LA BASE DE LA DETERMINACION A) Y LOS COEFICIENTES DE REGRESION PREDETERMINADOS QUE SE DERIVAN DE LA CALIBRACION DE MULTIVARIACION CON RESPECTO A LA RELACION ENTRE LA ATENUACION DE INFRARROJOS EN AL MENOS UNA BANDA DE ONDAS Y LA CANTIDAD DE AGUA EXTRAÑA. LA INVENCION SE REFIERE ADEMAS A UN METODO SIMILAR PARA DETERMINAR LA DE PRESION DEL PUNTO DE CONGELACION DE LA MUESTRA. ADEMAS, LA INVENCION SE REFIERE A UN METODO PARA ESTABLECER UN CONJUNTO DE COEFICIENTES DE REGRESION PARA SU USO EN UN INSTRUMENTO QUE DETERMINA LA CANTIDAD DE AGUA EXTRAÑA O LA DEPRESION DEL PUNTO DE CONGELACION DE UNA MUESTRA DE LECHE.
