| ABSTRACT This study aimed to dry ‘bacaba’ (Oenocarpus bacaba Mart.) pulp under different thermal conditions, fit different mathematical models to the dehydration curves, and calculate the diffusion coefficients, activation energy and thermodynamic properties of the process. ‘Bacaba’ fruits were meshed to obtain the pulp, which was dried at temperatures of 40, 50 and 60 °C and with thickness of 1.0 cm. Increase in drying temperature reduced the dehydration times, as well as the equilibrium moisture contents, and drying rates of 0.65, 1.04 and 1.25 kg kg min-1 were recorded at the beginning of the process for temperatures of 40, 50 and 60 °C, respectively. The Midilli’s equation was selected as the most appropriate to predict the drying phenomenon, showing... |

| ABSTRACT Native palm trees are highly important plant resources for the Amazon region; however, despite the great diversity and utilities, few species have been studied, requiring more comprehensive studies on quality and composition for species not yet explored. The aim of this study was to evaluate the quality of fruits and oils of palm trees from the Brazilian Amazon and to identify potential uses. Fruits from five palm trees (bacaba, buriti, inajá, pupunha, and tucumã) were evaluated for total mass, length, diameter, and yield, soluble solids (SS), titratable acidity (TA), pH, SS/TA ratio, total soluble sugar (TSS), reducing sugar (RS), total pectin (TP) soluble pectin (SP), and starch. The oils from the edible portion of fruits were evaluated for... |
