Density of banana puree as a function of soluble solids concentration and temperature Original Research Article

Density of banana puree was determined in a concentration range from 10 to 80oBrix and temperatures between 5 and 80 °C. Density values were found to increase with the increase of soluble solids concentration and the decrease of temperature. The results were analyzed to obtain this property as a function of temperature and soluble solids concentration and an equation, statistically significant at a confidence level of 99%, was proposed. For each different concentration, density variation with temperature was found to follow an Arrhenius-type relationship, with activation energy values between 748.36 and 1137.36 J/g-mol and all equations were statistically significant at a confidence level of 99%. A relationship between soluble solids concentration and activation energy was also obtained.
