In Fig. 7, the moduli of the mixed systems, also presented in Table S1, are compared to those of a WPI gel at 13.2% (w/w) total protein concentration, representing the continuous phase (gel matrix). For lower particle volume fractions, either at V ¼ 0.11 or
V ¼ 0.15, there was a small decrease in the final G0, whereas when the particle volume fraction was increased to V ¼ 0.25, we have observed a pronounced decrease in the final G0, suggesting that protein particles do not strongly interact with the proteins in the
