“…Hydration kinetics equations were optimized and a hydration model followed by a computer program was developed to calculate the reaction rate constant K and the reaction order n. This model presented that the hydration process of the binary system at low temperature could be divided into three stages, namely, nucleation and growth (NG), interactions at phase boundaries (I), and diffusion (D). …”

“…The results showed a lower degradation of TPC (10.98 ± 6.04%) and epicatechin (8.05 ± 3.01%) at 130 °C and 10 min of roasting, while a total degradation of epicatechin and a 92.29 ± 0.06% degradation of TPC was obtained at 200 °C and 50 min. Reaction rate constant ([Formula: see text]) and activation energy ([Formula: see text]) were 0.02–0.10 min(−1) and 24.03 J/mol for TPC and 0.02–0.13 min(−1) and 22.51 J/mol for epicatechin, respectively. …”

“…However, mostly they have high over-potentials and slow kinetics, that is why they require electrocatalysts to lower the over-potential of the reactions and enhance the reaction rate. The commercially used catalysts (e.g., ruthenium nanoparticles—Ru, iridium nanoparticles—Ir, and their oxides: RuO(2), IrO(2), platinum—Pt) contain metals that have poor stability, and are not economically worthwhile for widespread application. …”
