Density of banana puree was determined in a concentration range from 10 to 80degreesBrix and temperatures between 5 and 80 degreesC. 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. (C) 2002 Published by Elsevier Science Ltd.
