Abstract
The physical properties of coffee solutions were determined for temperatures close to the freezing point. Rheological behaviour, freezing curve, density, and their relationship between coffee mass fraction and Brix degrees were determined for coffee mass fractions between 5 and 50% (wet basis) in the -6 to 20 degrees C temperature interval. Values of viscosity varied from 1.99 to 1037 mPa center dot s and values of density from 1000 to 1236 kg center dot m(-3). The freezing curve was generated using the undercooling method, giving values within freezing curves for food fluids. The results were used to generate mathematical models to predict viscosity, freezing point depression, and density as a function of coffee mass fraction and temperature.
