The viscosities of supercooled liquid fructose and glucose are measured between a lower viscosity limit corresponding to 95°C and an upper limit of about 10 6 Pa.s. The glass transition temperature of fructose is estimated from the viscosity data using different extrapolation procedures. The Vogel‐Tamman‐Fulcher and power‐law equations gave estimates of 283K and 289K, respectively and the Williams‐Landel‐Ferry equation 286K. These values are in agreement with recent calorimetric determinations of the glass transition temperature.
