Figure 2.

The average size and zeta potential change in response to different amounts of the adding protein.

Notes: (A) Average size change in response to different addition amounts. (B) Zeta potential change in response to different addition amounts. (C) Average size change in response to different addition orders. (D) Zeta potential change in response to different addition orders. Four addition orders: HSCO represents protein, surfactant, co-surfactant, and oil; SHCO represents surfactant, protein, co-surfactant, and oil; SCHO represents surfactant, co-surfactant, protein, and oil; SCOH represents surfactant, co-surfactant, oil, and protein. *P<0.05 is considered as a difference; **P<0.01 is considered as a significant difference.
