Specific weight of 'a?aí' pulp as a function of total solids content and temperature

摘要

> face="Verdana" size="2">This work was realized to determine the specific weight of "açaí" (Euterpe Oleracea Mart.), pulp density in three concentrations (15.2, 12.5 and 9.7%) and at five temperatures (10, 20, 30, 40 and 50 oC). The densities were determined by experimental and theoretical methods. The experimental data were obtained using the pycnometric method. The theoretical data were obtained using models proposed in literature and by an equation proposed specifically for "açaí" pulp. The values of densities determined experimentally varied between of 1,007.2 and 1,024.9 kg m-3, respectively. The differences between the experimental values and the theoretical results in all the cases were found to be less than 1.2%.
