Photoluminescence Spectral Patterns and Parameters of Milk While Souring

Round 1

Reviewer 1 Report

In brief, since the article presents only a few experiments/characterizations of the milk, this author considers that the manuscript must be improved in terms of experiments performed or variables tested, and resubmit as a new manuscript.

The phrase “Whatever chemical reaction causes the change in the luminescent properties of the dairy products, anyway, it can be used as a marker of their souring” reflects the manuscript's lack of scientific quality. It is the responsibility of the authors to look for information that aids in understanding the encountered phenomena.

The manuscript needs an extensive language revision and editing.

The authors thank the Reviewer for the careful reading of the Manuscript and for the comments made. Major changes have been made.

This research is exploratory and will be continued in the future, taking into account the results obtained and the comments and recommendations made. Data on changes in other milk parameters have been added to the text of the manuscript: fat content, protein content, SNF, acidity (lines 119-223, Table 2).

 

The phrase “Whatever chemical reaction causes the change in the luminescent properties of the dairy products, anyway, it can be used as a marker of their souring” reflects the manuscript’s lack of scientific quality. It is the responsibility of the authors to look for information that aids in understanding the encountered phenomena.

 

This phrase has been removed from the text of the Manuscript. A discussion of the results has been added to the Results and Discussion section (lines 292-298, 318-324) and new sources of information [27-29]. The results obtained by the authors are consistent with the results of [26-29]. At the same time, in this study, we extend them to the processes of milk souring for the subsequent development of a photoluminescent module for their control.

Reviewer 2 Report

The review manuscript "Photoluminescence Spectral Patterns and Parameters of Milk, While Souring" lacks in some parts as well others well described. The text is well written, and the research objectives were adequately answered by the conclusions.

There are points needs to be addressed. The research is important for the scientific community given the lack of information in the discussion. The authors need to provide more discussion of this work. Importantly, the authors should provide more discussion on the future perspectives of the presented research in the abstract, introduction, and conclusion to sublimate manuscript.

Please check that the letters are properly capitalization.

 

Please check that the font and format of the title of the same level are correct.

Please give the recommendations for further work.

 

 Minor editing of English language required

You can used this refrence: https://doi.org/10.3390/dairy3020030

The authors thank the Reviewer for the careful reading of the Manuscript and for the comments made.

We used the link and put the information in the Introduction section (lines 89-91) and in References (link [20]).

 

Because you work on the milk you should add the chemical compostion of milk.

 

Information about the chemical composition of milk and its change in the process of souring has been added to Section 2.1. (lines 151-157) and Table 2 (lines 219-223).

 

You need to compare with the traditional device to give this method the validation.

 

This research is exploratory. At further stages, this method will be compared with other methods and devices. At this stage, we used the titrimetric method for determining acidity (lines 160-175) and the ultrasonic method for determining other milk parameters (lines 151-157) as an arbitration method.

 

What are the values for these parameter that indicate the milk is good or no?

 

The values of milk quality parameters are presented in lines 137-145.

 

 

Add drawbacks of this method. Add future prospective here.

Information about the shortcomings of the method and future potential clients has been added to the text of the Manuscript (lines 361-366).

Reviewer 4 Report

The researchers investigated the interactions between spectral patterns and absorption parameters in cow's milk using non-destructive spectral measurements.

 

·      The sentences and the paragraphs in the introduction is too short. It could be improved by adding more related info with their citations.

·      Materials and methods: how many milk samples were tested? Some info was provided in the results and discussion section, but it should be moved to the materials and methods.

·      Reference analyses were repeated how many times?

·      The authors were mentioned the 290, 232, 262, 270, 284, 322, 385, and 442 nm are important, but what are they corresponds for (which chemical structures)?

·      The discussion part should be improved by adding more literature studies. It is very insufficient as it is.

The English language of the manuscript does not have too many problems, but still the authors should check the manuscript thoroughly.

 The sentences and the paragraphs in the introduction is too short. It could be improved by adding more related info with their citations.

The authors thank the Reviewer for the careful reading of the Manuscript and for the comments made.

The introduction has been improved by adding a text part (lines 28-32, 53-58, 89-91, 97-108, 112-115, 130-145), Figures 1 and citations.

 

Materials and methods: how many milk samples were tested? Some info was provided in the results and discussion section, but it should be moved to the materials and methods.

 

7 milk samples were tested. The information has been added to the Materials and Methods section.

 

Reference analyses were repeated how many times?

 

Reference analyses of acidity were carried out in threefold repetition (lines 174-175). Measurements of other milk parameters were also carried out in threefold repetition (lines 152-154 and Table 2).

 

The authors were mentioned the 290, 232, 262, 270, 284, 322, 385, and 442 nm are important, but what are they corresponds for (which chemical structures)?

 

The information was added to the text of the Manuscript (lines 292-298, 318-324). In further studies, measurements are supposed to be carried out with the constituent components of milk (fat, casein, lactose, etc.) for their spectral identification.

 

 

The discussion part should be improved by adding more literature studies. It is very insufficient as it is.

The discussion part was improved by adding additional literary studies [27-29].
