Response to reviewer

****Thank you so much for the comment. All queries have been responded.

1- Please, consider an updated title

***This title covers the details of our work properly, by focusing on the quality of squid mantle cut treated with mint extract and high-pressure processing during refrigerated storage. Thus, we prefer to keep the present title.

2- Please, update the section of introduction with recent information from recent References (2022-2024), to make your study more interesting and more significant to the reader.

for ex. Coupling ozone with microbubbles (OMB) water for food disinfection: Effects on microbiological safety, physicochemical quality, and reducing pink discoloration of jumbo squid (Dosidicus gigas) – ScienceDirect

Evaluating the effects of nanoparticles combined ultrasonic-microwave thawing on water holding capacity, oxidation, and protein conformation in jumbo squid (Dosidicus gigas) mantles – ScienceDirect Animals | Free Full-Text | Innovative Seafood Preservation Technologies: Recent Developments (mdpi.com)

***Actually, the recently published information had been provided in the introduction (2021 – 2023: 5 papers), which were also related to the scope of present study. However, the first reference suggested by reviewer is related to the use of ozone-microbubble (OMB) water for disinfection of squid prior to refrigerated storage. The second one is related to the use of magnetic nanoparticles in combination with microwave and ultrasonic waves on the water holding capacity, oxidation of protein and lipid, and protein conformation, jumbo squid mantles. Those works are not related with our work, which focused on the use of HPP and natural extract on shelf-life of refrigerated squid mantle cut.

Since we are working on the textural improvement and quality of giant squid, we will cite those two references in our new manuscript, which will be submitted within 1-2 months. 

3- In the section 2.2. and 2.4 please try to edit these steps referring to their references sources in order to be clearer and more scientific. Please write these steps from the ref.

***The references were cited for all procedures used in the present study. The necessary details were provided and some important methods were described in details. The repeated general details from the former literatures should be avoided to reduce the plagiarism.

4- Please, provide a better figures of 2,3 and 4 of higher resolution, because the current figures is not clear

***Sorry for the poor presentation of those three figures. We found that the sizes of figures are small and the details in X and Y-axis are hard to follow. To tackle such as drawback, the size and resolution of all figures has been improved. Please see Figure 2, Figure 3, and Figure 4.

5. Comments on the Quality of English Language

Dear, this research needs a simple linguistic review, and it is written in good language, but it is better for it to be reviewed by a native English speaker.

***Thank you for the comment. The authors have cross-checked the manuscript. The software’ Grammarly’ has been used to avoid grammatical errors for the whole manuscript.

***The “ME-80” has been replaced with “ME” for the consistency throughout the text. Please see line 87.

  1. Line 120 - Why was this processing time chosen? The pressure is justified in line 48. The justification for the time is missing.

***The time of high-pressure processing (HPP) has been selected (5 min) based on the result of “Inactivation of planktonic cells by HPP” as discussed in section 3.2. Please see line 245 – 248 and 261 – 262.

It was found that “lower survival of cells was noted for Pseudomonas aeruginosa (PA) and Shewanella spp. (SWS) after HPP at 400 MPa for 5 and 7 min, compared to those of PA-HPP and SWS-HPP treated for 1 and 3 min (p<0.05). No difference between counts of PA-HPP and SWS-HPP at 5 and 7 min was found (p>0.05). Overall, HPP treatment time had the potential influence on inactivation of cells. Therefore, HPP at 400 MPa for 5 min was selected for microbial inactivation.”.

Reviewer 4 Report

Comments and Suggestions for Authors

This study aimed to investigate the combined effect of mint extract (ME) and HPP on quality changes of squid mantle cut during refrigerated storage. The study is interesting for students, academics and general public; however, some comments should be attended.

Lines 105 and 116; please mention how many replicates were used for each treatment and control.

Line 200: A completely randomized design is not enough to statistically analyze the results. In the treatments the authors have the interaction ME extract and HPP, therefore I suggest to analyze the data with a factorial design with blocks; where factor A could be ME concentrations (0, 200, 400), factor B the HPP (200, 400) and storing days the blocks (0,3,6,9,12,15) because it is well known that the more storing days of SMC, the more effects on SMC could be observed in some variables.

Figure 2,3, 4 are difficult to read, use bigger figures please.

 

Table 2 and Figure 5: why day 12 in M4P4 if authors stated a storing period of 15 days?

Response to reviewer

This study aimed to investigate the combined effect of mint extract (ME) and HPP on quality changes of squid mantle cut during refrigerated storage. The study is interesting for students, academics and general public; however, some comments should be attended.

****Your understanding in our work is highly appreciated. Thank you so much for the invaluable comments and suggestions. All queries have been responded and the corrections have been made as highlighted in turquoise.

  1. Lines 105 and 116; please mention how many replicates were used for each treatment and control.

***Thank you for comments. All experiments were carried out in triplicate. This detail was mentioned in the text. Please see line 201 – 202.

  1. Line 200: A completely randomized design is not enough to statistically analyze the results. In the treatments the authors have the interaction ME extract and HPP, therefore I suggest to analyze the data with a factorial design with blocks; where factor A could be ME concentrations (0, 200, 400), factor B the HPP (200, 400) and storing days the blocks (0,3,6,9,12,15) because it is well known that the more storing days of SMC, the more effects on SMC could be observed in some variables.

***Thank you for your insightful suggestion. We decided to use Completely Randomized Design in our study since we want to find the best condition for extending the shelf life of squid ring treated with mint extract in combination with HPP. Therefore, we considered each treatment as the individual sample and make comparison at each storage time. For the same treatment, the function of time was also analyzed to elucidate the influence of storage time on quality of different samples. Overall, we could end up with the best treatment for shelf-life extension of squid ring, in which the goal of study was achieved.

  1. Figure 2,3, 4 are difficult to read, use bigger figures please.

***The resolution and size of all figures has been improved as per the reviewer’s suggestion. Please see Figure 2, Figure 3, and Figure 4. Please see line 304 – 306, 398 – 400, and 549 – 550.

  1. Table 2 and Figure 5: why day 12 in M4P4 if authors stated a storing period of 15 days?

***It is true that the total period of storage was 15 days. However, M4P4 had total viable count (TVC) higher than 6 log CFU/g after 15 days. This count is not acceptable for human consumption. Therefore, M4P4 at 12 days, which was the longest storage time, while TVC was still under the limit, was selected for sensory evaluation and next-generation sequencing (NGS). This detail had been mentioned in text. Please see line 185 – 187.
