Time sweep curves for chitosan 2%/gelatin 10% A) chemical gelation at 37 °C and B) subsequent physical gelation at 12 °C; equally for C) physical-co-chemical gelation at 21 °C and D) subsequent physical gelation at 12 °C, with varying enzyme concentration. Solid lines represent chitosan 2%/gelatin 10% physical gels (no mTGase) at the reaction temperature. mTGase concentration of 10 (▪), 20 (●), 30 (▴) and 40 (♦) U/ggelatin, and G′ are shown by filled symbols are shown in increasingly darker shades, G″ by empty symbols (all plots for G′ are above the corresponding G″ plots).
