* E′ and tan δ represent the storage modulus and integral loss factor of CRS and TRS samples at 1 Hz frequency respectively in DMA tensile mode. T_E′ and T_tanδ represent the peak temperatures for the storage modulus and the loss factor curves, which are corresponding to the protein relaxation of γ, β, α and α_c. ΔT_E′ and ΔT_tanδ represent the peak temperature differences between TRS and CRS samples at γ, β, or α-relaxation regions. The E′ and Tan δ values have an error bar of ±0.3, the T_E′ and T_tanδ values have an error bar of ±0.5 °C.
