Different lowercase letters (a–d) between the treatment and control groups indicate significant differences (p <0.05); T_2b, T₂₁, T₂₂, and T₂₃ indicate the capping relaxation times of water molecules in different states of the gel. P_2b, P₂₁, P₂₂, and P₂₃ indicate the proportions of peak areas of water molecules in different gels.
