Efecto de la temperatura en la densidad de la leche entera bajo alta presión

Abstract

El procesado con alta presión se está convirtiendo en una eficaz tecnología de conservación. Con ella, se prolonga la vida útil de los alimentos, manteniendo sus cualidades. Para controlar y optimizar la uniformidad de los tratamientos, cada vez se emplea más, la modelización matemática. La realización de los correspondientes cálculos, requieren disponer de las propiedades físicas de los alimentos. Entre ellas está la densidad. Ante la carencia de estos datos, se ha llevado a cabo la medida de la densidad de la leche entera entre 0 y 60 ° C a presiones de hasta 350 MPa. Para ello, se ha empleado un piezómetro de volumen variable dotado de pistón. Debido a la presencia de solutos, la densidad de la leche ha resultado ser de aproximadamente un 3% mayor que la del agua para cada condición de presión y temperatura, aumentando con la presión de una manera similar a la del agua. La dependencia observada con la temperatura fue irregular, en comparación con la del agua entorno a los 150 MPa. Este comportamiento está probablemente relacionado con los conocidos
