Water diffusion between pectin films. The diffusion of water was assessed between adherent gel-phase films (40% w/w W_c) and glass-phase films (10% w/w W_c). (A) Water content was assessed at time = 0, t = 5 min and t = 10 min. Each column represents the mean water content of 4 films ± 1 SD. (B) Water content was assessed at various intervals from t = 0 to t = 1 h. Each data point represents the mean water content of four films ± 1 SD. Since the diffusion coefficient of water through the pectin medium at 25 °C is unknown, the data is plotted relative to theoretical diffusion coefficients of 0.00092 mm²/s (dashed line), 0.00183 mm²/s (solid line) and 0.00732 mm²/s (dotted line) for comparison.
