Debittering of Grape Juice by Electrospun Nylon Nanofibrous Membranes: Impact of Filtration on Physicochemical, Functional, and Sensory Properties
Round 1
Reviewer 1 Report
The manuscript entitled 'Debittering of Grape Juice by Nanofibrous Membranes: Impact of Filtration on Physicochemical, Functional and Sensory Properties' is a very intersting article that uses novel memberane technology for debittering process without the use of chemical additives. Moreover, the quality of manuscript is very good. However I recocomend authors to go for english grammar and spell check. I have appended all the comments in attached PDF.

Reviewer 2 Report
Dear Authors,
Your Manuscript presents an application of electrospun nylon-6 nanofibrous membranes (NFM) for filtration of grape juice. The English writing and presentation of the data were nice and I congratulate you for that. But, unfortunately, you focused on the food science side with no relevant work on the used polymer membrane (you changed only the thickness of the membrane). Since the readers of the journal are more interested in polymer sciences. I think that either the article has to be submitted to food science journal or at least add some more work on the used membrane for example:
i) Explain the electrospinning technique and condition and link them to the resulting fiber diameter and membrane porosity
ii) Discuss the effect of concentration PA6/HCOOH and polymer molecular weight on the structure and porosity of the prepared membrane, etc…).
iii) The fiber diameter and the resulting porosity will be more relevant parameters for filtration so better to focus on how to change them.
