Round 1

Reviewer 1 Report

What kind of lactic acid was used (purity, aqueous solution?) + provide details of the supplier.

It is necessary to expand the discussion and description of the results. Give several comparisons with other extractions, and extraction efficiency. Alternatively, a comparison of different types of deep eutectic solvents-like mixtures/Low‐Transition‐Temperature Mixtures (LTTMs) from the point of view of extraction.

Is your methol and lactic acid mixture really Deep eutectic solvents?

In fig. 1 you have different molar ratios and you call it DES, then it cannot be DES. See the work https://doi.org/10.15376/biores.17.3.3880-3882, and do not use the term DES.

Reviewer 3 Report

The quality of the manuscript does not meet the journal.

1. The novelty of the manuscript was missed. 2. The manuscript is not a full manuscript, it is like a short communication.  3. The references were not appropriate. 4. The results and discussion doesn't justify the literature review. 5. Abstract and conclusion must be rewritten, it is not acceptable in the current format. 6. Most importantly, all sections like the methodology section are not the same as a scientific paper.

Reviewer 4 Report

Abstract: 2-3 lines are sufficient for introduce the issue. After, must be direct to work done.

 

Material and methods: most detail on IR technique is necessary, for example, which signals are used for identified the oleic acid?

 

Results and discussions: Structures of menthol and lactic acid could be useful to reader for understand the interpretation of the authors. Some comments about cost comparative of the eutectic solvent method and other methods could help to improve the manuscript.
