In order to choose appropriate emulsifier, we prepare different WPI concentration of 1.0-2.0 wt% and found the emulsion formulated with 1.5 wt% WPI had smaller size and medimum zeta potential, so it was described to the optimize condition. For clarity, we have also revised the corresponding positions in the manuscript.
The obtained emulsion gels are well characterized in terms of their structure and rheological and mechanical properties.
