DENSITY DATA FOR AQUEOUS-SOLUTIONS OF GLUCOSE, FRUCTOSE AND INVERT SUGAR

The density of aqueous glucose, fructose, and invert sugar solutions w as measured as a function of mass fraction and temperature. After the respective mass fraction had been determined at the Institut fur Techn ologie der Kohlenhydrate an der Technischen Universitat Braunschweig w ith an uncertainty of 0.002%, the density was hydrostatically measured at the Physikalisch-Technische Bundesanstalt Braunschweig with a rela tive uncertainty of 1 . 10(-5). Polynomials are given for the density as a function of concentration and temperature, and for practical appl ications, also for the density as a function of mass fraction and temp erature and for mass fraction as a function of density and temperature . The results will be presented to the International Commission for Un iform Methods of Sugar Analysis (ICUMSA) at its 22nd meeting in Berlin from May 24 to 29, 1998.
