The manuscript is presented in a well-structured manner.The references cited are relevant and current, mostly published within the last three years.The results of the manuscript are reproducible using the information in the methods section, but some minor explanations are missing.
Line 478 and 485: Are the gel continuous phase and the protein-emulsion mixture the same thing? This section is a bit confusing so I would suggest authors include a Table with all the sample formulations/conditions tested.
