Round 1

Reviewer 1 Report

1.      The paragraphs in the introduction are too long. Please divided them into small paragraphs, each portraying information about one key topic.

2.      Authors are suggested to include a figure in the introduction that depicts a comprehensive overview of the topic.

3.      Please provide the regulatory aspects of these edible coating systems.

4.      Please discuss the challenges as well as advantages associated with each kind of coating system.

5.      Please includes some figures that gives through information about the different coating mechanisms.

 

6.      Please divide the conclusion section into two paragraphs one providing the summary of the existing information and the other providing the future outlook.

Please correct the grammatical errors.

Reviewer 2 Report

The authors tried to review edible coatings in the preservation of meat in the nano-encapsulated natural bioactive aspects. The emphasis is interesting, but the review is not comprehensive.

1. The references should be updated with more recent literature, especially in the last year. In line 216, the author stated "Recently, Xiong et al. ...". We can't say a study in 2020 as recently. As a review, we can't just put the literatures in our endnote together, we have to update and put forward some points to readers. 

2. Based on the title of the review, I would expect news about nanoencapsulation and bioactives. But most of the review is about biopolymer (cabohydrates) coating on meat. The authors should more focus on bioactives. There are a lot reviews about biodegradable package on food or meat, what's new the review could provide to readers? The authors should think about it.

3. I suggest the authors should add a part about the type of the bioactives encapsulated within edible coating. Which kind of bioactive are commonly used and how do they encapsulated by various methods. 

4. I suggest the authors add a schematic illustration to show the method of bioactive nano-encapsulated edible film making. I think there are different methods for the film making in literature. As a reader, I think this part will help the other researchers.

Ans: Thank you very much for your suggestion, the role of encapsulation in the use of bioactive compounds in edible films or coatings has been added.

 

 

 

3. I suggest the authors should add a part about the type of the bioactives encapsulated within edible coating. Which kind of bioactive are commonly used and how do they encapsulated by various methods.

Ans: Thank you very much for your comment, different bioactive compounds incorporated in edible films and coatings have been discussed in the paper.

 

4. I suggest the authors add a schematic illustration to show the method of bioactive nano-encapsulated edible film making. I think there are different methods for the film making in literature. As a reader, I think this part will help the other researchers. 

Ans: It has been added in Figure.
