THERMOPHYSICAL PROPERTIES OF JACKFRUIT PULP AFFECTED BY CHANGES IN MOISTURE CONTENT AND TEMPERATURE

摘要

Thermophysical properties of jackfruit (Artocarpus heterophyllus L.) pulpnaffected by temperature and moisture content were analyzed. Density (r), heatncapacity (cp) and thermal diffusivity (a) were experimentally determined atnmoisture content between 65% m/m and 95% m/m, and temperatures between 5nand 85C. Then, thermal conductivity was calculated from experimental resultsnof thermal diffusivity, specific heat and density. The empirical models for eachnproperty as a function of moisture content and temperature were obtainedn(R2 u0002 0.90). Estimated equations were fitted to the experimental data forndensity and specific heat, and the accuracy of those equations was checked.
