外文摘要：This study aimed to determine the thermophysical properties and antioxidant capacity of buriti pulp with concentrations of 7, 9, 11, 13, and 15 degrees Brix. Total solids and moisture content were determined in an oven, and the specific mass was determined by the pycnometer method, while the specific heat, thermal diffusivity, and thermal conductivity were obtained using the KD2 Pro thermal properties analyzer. The antioxidant capacity was determined by the 2,2 '-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods. At high concentrations, total solids and specific mass increased while moisture content decreased, and the soluble solids concentration did not influence specific heat, thermal diffusivity, and thermal conductivity. The antioxidant capacity of buriti pulps ranged from 0.07 to 10.45 mu mol Trolox/g sample for the ABTS method and from 293.77 to 411.46 mu mol Trolox/g sample for the DPPH method.
