Round 1
Reviewer 1 Report
Comments and Suggestions for Authors
I suggest the following revision for your feedback:
"While the research article presents intriguing findings, I would recommend revisiting the manuscript before publication to address some minor areas for improvement:
The introduction section should be revised to include the application or product for utilizing the sunflower seed cake.
References should be provided for the spray-dry methods mentioned.
Instead of using a, b, c, d in the tables and figures, it is preferable to use a-d for clarity.
The manuscript requires language refinement, including correcting English grammar, syntax, and typographical errors throughout.

Reviewer 2 Report
Comments and Suggestions for Authors
This manuscript describes the effects of addition of sunflower seed cake washouts (SSCW) to whey on the physical and chemical properties as well as sensory attributes of the mixed feed powders. The topic is interesting but need minor revision.
1. Inclusion of sensory test results of “Control” sample (Wh) will be helpful for readers to understand the effects of addition of Wh on the sensory quality of the feeds. Would the authors add the sensory test results of “Control” (Wh) in Tables 6-7.
2. In the section Sodium Dodecyl Sulfate–Polyacrylamide Gel Electrophoresis (SDS–PAGE) analysis, the possible mechanism of the appearance of bands with a molecular weight between 25 and 37 kDa should be discussed in more details.
3. About the ABSTRACT, it looks like an introduction. Some important results might be included in the ABSTRACT.
4. Format of references list should be checked carefully: LWT should be replaced by LWT-Food Sci. Technol.

This manuscript describes the effects of addition of sunflower seed cake washouts (SSCW) to whey on the physical and chemical properties as well as sensory attributes of the mixed feed powders. The topic is interesting but need minor revision.
- Inclusion of sensory test results of “Control” sample (Wh) will be helpful for readers to understand the effects of addition of Wh on the sensory quality of the feeds. Would the authors add the sensory test results of “Control” (Wh) in Tables 6-7.
Control sample (sweet whey) was not included in the study because the sensory evaluation panel was trained toward the sensory descriptors on the basis of the powdered whey sample (considered as a commercial product). Whey was presented to panelists, and they were asked which traits (descriptors) related to the product were the most important for them. The main objective for the sensory analysis was to describe the new products but not the comparison of the product with the "control" standard sample.
- In the section Sodium Dodecyl Sulfate–Polyacrylamide Gel Electrophoresis (SDS–PAGE) analysis, the possible mechanism of the appearance of bands with a molecular weight between 25 and 37 kDa should be discussed in more details.
The stronger appearance of the bands in the case of samples in which the addition of sunflower seed cake washouts was more than 80% was probably linked to the increase MW of the conjugates formed. In the rest of the analyzed sample, the degree of the conjugation could be lower, thus not so visible as in the case of the mentioned above samples. Interestingly, this also indicated that the binding capacity of whey and SSCW was not effective when less than 80% of SSCWs was added to whey (v/v).
Line 627-629: Thus, the stronger formation of molecular fraction between 25 and 37 kDa was noticed, pointing to the possibility of binding by phenolics present in washouts with whey proteins that was confirmed by increased intensity of these bands. It was probably linked to increase in MW of the conjugates formed [39, 55]. What is more, it was indicated that the binding was not effective in the case of sample composed of whey and SSCW added below 80% (v/v). This may be also linked with the content of total phenolic components as determined by the Fast Blue BB method indicating the binding of those constituents to whey proteins [56].
- About the ABSTRACT, it looks like an introduction. Some important results might be included in the ABSTRACT.
It was done according to the suggestion.
- Format of references list should be checked carefully: LWT should be replaced by LWT-Food Sci. Technol.
It was done according to the suggestion.
Reviewer 3 Report
Comments and Suggestions for Authors
The study is interesting, it could be enriched in some parts, as detailed in the comments.
Detailed comments
Line 150: Check the text “milled SCC with 7 800 g”
Spray drying: Add more information to spray drying experiments. How did you get the powders? How did you chosen the experimental parameters? Have you done any previous experiments?
Physical properties: Among the physical properties described, the authors do not consider the particle size of the powders and the powders morphology. Do the authors have this information? Do you have any information about the stability of the powders?
Porosity: Specify the pb and pt terms in the equation.
Figure 4: Improve resolution
Line 624: “Wh6/SSCW6” Check, there is a mistake.

Detailed comments
- Line 150: Check the text “milled SCC with 7 800 g”
I was changed according to the suggestion:
Line 150-152: The removal of phenolics from SSC (de-phenolisation) [6], was made by washing 100 g of grounded SSC with 7 800 g of cold tap water (17 °C) for 15 min (established experimentally).
- Spray drying: Add more information to spray drying experiments. How did you get the powders? How did you chosen the experimental parameters?Have you done any previous experiments?
The experimental setup was established based on the literature data as already mentioned in the comment to Reviewer 1 (Jafari, S. M., Samborska, K. Spray Drying for the Food Industry: Unit Operations and Processing Equipment in the Food Industry Eds.; Woodhead Publishing: Cambridge, MA Kidlington, 2024) as well as based on the preliminary studies. The powders were obtained according to the description provided in the Methods section, namely: air inlet temperature of 180 ± 2 °C; an average air outlet temperature of 78 ± 4 °C; feed pump flow rate of 3 L/h; the nozzle air pressure of 0.15 MPa; and the aspiration rate 100%. The parameters were set to avoid overheating of the whey as well as ensure the highest quality of powder.
- Physical properties: Among the physical properties described, the authors do not consider the particle size of the powders and the powders morphology. Do the authors have this information? Do you have any information about the stability of the powders?
The particle size of the powders was not considered at this point, and neither did the powder morphology and stability tests. The main aim of the study was to check the feasibility of spray drying as a method to obtain powders based on sunflower seed cake washouts and whey. Moreover, the quality tests focused on the phenolic content as well as sensory tests. However, the Authors are thankful for this comment and further physical tests will be for sure considered in the future.
- Porosity: Specify the pb and pt terms in the equation.
Equations were added according to the suggestion.
- Figure 4: Improve resolution
It has been done according to the suggestion.
- Line 624: “Wh6/SSCW6” Check, there is a mistake.
It was corrected.
