Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The abstract should be restructured

Please mention the significance of adding blueberry extract, particularly in terms of its potential functional benefits, antioxidant properties, and interaction with whey proteins.

Ensure the abstract follows a structured format: Background, Methods, Key Findings, and Conclusion for better readability and impact.

Results and Discussion:

Highly Recommended: Please include FTIR results to analyze the effect of polyphenols on whey protein interactions. This will provide valuable insights into changes in secondary structure and their correlation with gel strength and formation mechanisms.

Update the reference list in the discussion section by incorporating recent studies (last 5 years) to strengthen the explanations, particularly regarding protein-polyphenol interactions, fermentation-induced gelation, and rheological properties.

Expand the discussion on the role of polyphenols in modulating gel properties, including their influence on protein cross-linking, water retention, and mechanical strength.

A thorough grammar and language revision is needed throughout the manuscript to improve clarity and readability.

Reviewer 2 Report

Comments and Suggestions for Authors

The research is very interesting and useful, but I have some comments on the presentation.

  1. The objectives should be made more specific
  2. There should be more references to support the introduction and results
  3. Please describe exactly the type of colorimeter and the evaluation of the data of color
  4. What exactly do delta L, a and b values mean? I think it would be easier to understand if Lab values were used instead of differences.
  5. Why are the viscosity and frequency sweep not plotted over the entire measurement range? Please explain your choice or correct the figures.
  6. The G' and G" curves should always be plotted together, because their relationship with each other tells us a lot about the structure and stability of a product. Please correct the figures.

Reviewer 3 Report

Comments and Suggestions for Authors

The paper is quite remarkable, however the findings need to be discussed more meaningfully.

The production of gels should be checked and probably re-writen as to make how gels are prepared, how the amounts of gel ingredients were decided.

Suggestions are given in the text.

There are some conflicts of English usage.
