| Avaliaram-se as características físicas do fruto e físico-químicas da casca do mangostão colhido em diferentes períodos da safra (início, meio e fim). As características físicas dos frutos variam significativamente (p<0,05) do início ao fim da safra, e observou-se que a média de peso dos frutos variou de 91,33 a 50,82 gramas, e a casca representa, em média, de 61,39 a 76,86% do peso total do fruto. A caracterização físico-química mostrou que a casca possui elevado teor de umidade (64,5 a 66%), fibras totais (24,9 a 29,1%), alta atividade de água (0,96 - 0,98), baixo valor energético (24,8 a 34,7 Kcal/100 g) e expressivo teor de antocianinas totais (25,9 a 63,9 mg/100 g), principalmente no período intermediário da safra. |

| ABSTRACT Sorption isotherms of flaxseeds were determined by static gravimetric method at temperatures 40, 60, and 80 ºC, over a relative moisture range of 10-95%. Six mathematical models were applied to analyze the experimental data. The modified GAB model showed the best fitting to the experimental data. The isosteric heat and differential entropy were determined by applying the Clausius-Clapeyron and Gibbs-Helmholtz equations, respectively. The isosteric heat and the entropy of desorption isotherm presented similar behavior, with a sharp change of 10% in the equilibrium moisture content. The enthalpy-entropy compensation theory was applied to the isotherms, indicating that they are enthalpy-controlled. |

| ABSTRACT: Processing of particles in a moving bed, such as a fluidized bed or a spouting bed, is commonly used in the operations of drying, coating, and granulation of particulate systems. This process has applications in the chemical, pharmaceutical and, presently, agronomical industries, especially for seed treatment/coating. This research aimed to analyze the fluid-dynamic behavior of fluidized and spouting beds with different air temperatures and loads of flaxseeds (Linum usitatissimum L.), with estimates of the fluid-dynamic parameters correlated to each process. The parameters were compared with the values obtained from classical correlations in the literature, with indications of associated percentages of deviation. Influence of fluid dynamics on... |
