FIGURE 5:

Longitudinal MRI study of egg white samples treated with 0.25 v/v% H₂O₂ for different durations (0, 0.5, 1, 1.5, 2, 2.5, 3 hours). (a) QUESP data. (b) Representative exchange rate $(K_{ex})$ map. (c) $K_{ex}$ increases immediately after H₂O₂ treatment and then decreases towards the baseline level over time. Longitudinal experimental data were fitted with first-order reaction kinetics (red dotted line), which allows us to estimate the produced hydroxyl ROS concentration over time (as labeled).
