It is opinion of the reviewer that this paper needs several corrections. My individual comments are listed below.

 

3 – It should be „Liquid”.

7-12 – Authors’ e-mail addresses and their initials must be added.

17 – Full name of “PLE”.

17, 221 and other lines – What does it mean “global extraction”?
19 – Interaction between temperature and time?

38-39 – It must be rephrased.

43 – It must e “Punica granatum …  (with italic).

52 – Difference between “ant-cancer” and “anti-tumor”?

&0 – It must be “Soxhlet”.

164 – Power of this bath?

168 – Silica gel particle size” The layer thickness?

172 – How was loaded?

124, 136 – The duplicated information.

196 – It should be “UV-Vis”.

198 – “R2” is a determination coefficient.

208 – It should be “were constituted”.

Table 1 Why the content of phenolic compounds is reported only for two treatments?

261 – It should be “Tukey’s”.

341 – It should be “…. Chromatograms at 340 nm …”.

398/407 – The initials not full names.

Reviewer 2 Report

The present study covers the research on the promotion of the no-waste technologies and the extraction of phenolic compounds from pomegranate by-products. According to my opinion, the new obtained knowledge can be useful for the industrial production of added-value phenolic containing ingredients. To improve the quality of the manuscript, I have certain questions as outlined below and suggest a few corrections:

  • In the introduction section please highlight the novelty of the study. There are a lot of studies performed in the area of PLE and Punica granatum. You should clearly indicate the relevancy and novelty.
  • Please explain the abbreviation PPCM in the first mention in the introduction section.
  • Line 97. the peels were separated from arils, not fruits. The whole is fruits that consist of peel (exocarp and mesocarp) and arils (seed with fleshy outer layer).
  • “S/F ratio” Please clarify.
  • Line 198. R2 is the coefficient of determination. Please change.
  • Line 185. The HPLC or UPLC analysis was performed? The columns and conditions seem to be UPLC.
  • Line 200. Please add a description of the regression analysis performed in the statistical section.
  • To what treatments (according to table 1) does the E1 and E2 correspond? Was the phytochemical composition determined with treatments 8 and 10? They are not significantly different in yield.

Reviewer 3 Report

This manuscript is well redacted, argued and discussed. Therefore, it is pleasant to read and understand.

Just a few comments: please revise the manuscript regarding italic forms for the scientific names of plants (eg. line 43).

Section 2: please add refs along this section. If the procedures were optimized during this work, the validation should be included.

Section 3: Please add the outputs concerning the optimization of extraction and statistical analysis/validation; equation which explains the best condition and predicted vs experimental optimum point.
