Abstract

The kinetics of hydrothermal behaviour of unpunched and punched tamarind (Tamarindus indica) seeds were determined at different temperatures (V-80°C). The kinetic parameters determined were hydration rate constant, equilibrium moisture content, frequency factor and activation energy. Punching of seed increases the hydration rate constant and the equilibn’um moisture content but reduces the activation energy compared to unpunched seeds. The hydration rate constant values for the unpunched seeds were 0.13, 0.16, 0.18, 0.31 and 0.38 h-’ at hydration temperatures of 25, 35, 50, 65 and 85°C. respectively; the corresponding values for the punched seeds were 0.37. 0.40. 0.41. 0.43 and 0.52 h -I. Linear relationships (r 20.92, p 10.01) were obtained between the rate of moisture absorption and average moisture content. The equilibrium moisture content also increases linearly (r 2 0.95, p 10.01) with an increase in hydration temperature.
