【 摘 要 】

The objective of this work was to study the hydration of grains of birdseed (Phalaris canariensis L.) at different temperatures. Dried birdseed beans were used embedded in distilled water at temperatures of 10, 25 and 45 °C. Increasing the temperature resulted in higher water absorption rate and the model of Peleg adjusted satisfactorily to experimental data. The effective diffusion coefficient increased with increasing temperature from 2.396 to 2.428 × 10-13 m2 s-1. The dependence of the effective diffusion coefficient on temperature can be described by the Arrhenius relationship, presenting, for the studied temperature range, the magnitude of the apparent activation energy for the process of 39.239 ± 4.3463.
