An Active Bio-Based Food Packaging Material of ZnO@Plant Polyphenols/Cellulose/Polyvinyl Alcohol: DESIGN, Characterization and Application

Round 1

Reviewer 1 Report

1-     I wonder whether the solubility of PVA film is only 5%. It’s far from reality.

2-     Why PVA???

3-     What about the interaction between PVA and extracted solution?

4-     Characterization of the extracted materials should be conducted to make sure that the extracted materials were pure polyphenols not containing sugars and other impurities.

5-     Why polyphenols and not anthocyanins?

6-     Please provide a typical image of the resulting films used as apple slice packaging materials rather than only showing the picture of the apple slice.

7-     What about the novelty of this research?

8-     Discussion needs to be improved and justification is needed.

9-     There are a number of related papers that are even not being addressed in this manuscript:

I would like to see the required revisions for reconsidering its potential for publication.
