Abstract

UN METODO PARA DETERMINAR EL COLOR O LA AMARGURA DE LA CERVEZA O AMBOS MEDIANTE LA ILUMINACION DE LA CERVEZA CON LUZ DE UNA LONGITUD DE ONDA PREDETERMINADA, TIPICAMENTE 400 (MAS MENOS) 30 NM, PARA CAUSAR ISO-{AL}-ACIDOS EN LA CERVEZA PARA SER FLUORESCENTE. LA FLUORESCENCIA ES DETECTADA SOBRE UN RANGO DE LONGITUDES DE ONDA, TIPICAMENTE DE 420 A 673 NM, USANDO UN ESPECTROFOTOMETRO DE FLUORESCENCIA. EL COLOR Y LA AMARGURA DE LA CERVEZA O AMBOS ES DETERMINADO MEDIANTE LA COMPARACION DE UNA SEÑAL DE SALIDA DESDE EL ESPECTROFOTOMETRO DE FLUORESCENCIA PARA LAS SEÑALES DE SALIDA ALMACENADAS PARA CERVEZAS DE COLOR Y AMARGURA CONOCIDOS.
