4.5. Integrative model: impact of thermal degradation during diffusion kinetics

The thermal degradation kinetics conducted under the same oxygen conditions as the diffusion kinetics show residual folate amounts slightly higher at the end of the thermal degradation kinetics for spinach (diffusion: 35%, thermal degradation: 40%) (Fig. 3). In contrast to this, in green beans, the residual ratio (C∞/C0), measured at the end of the diffusion kinetics, are higher than those measured at the end of the thermal degradation kinetics (diffusion: 59% at 45 °C and 43% at 65 °C; thermal degradation: 20% for both temperatures). In addition, residual ratios are obtained with very different compositions.
