The Impact of Sweetener Type on Physicochemical Properties, Antioxidant Activity and Rheology of Guava Nectar during Storage Time
Round 1
Reviewer 1 Report
Line 30: "test" should be "taste"
Line 160 – 184: does higher cloud value mean better product? Authors should please specify.
Line 204 -205: Is stevia able to do that as such low concentrations?
Entire results and discussion can be further improved. Authors should back their findings with relevant literature.

Reviewer 2 Report
The manuscript was to investigate the physicochemical property and antioxidant activity in guava nectar with sweeteners during refrigerated storage. The manuscript was of some interesting. However, please address the points below to revise it. General comments, 1. Please indicate why did you select those sweeteners as your target compounds. 2. Please add one more antioxidant activity test such as ABTS to compare your DPPH result. 3. In the GC analysis, please indicate why type of SPME injector you used. 4. In the result, it looks only small amount of compounds were identified in the GC column. Please add another type of column such as low polar one to analyze your samples and compare the results. 5. The graphs and tables were not prepared well. Please check and modify those again.Author Response

Reviewer 2 Report
The authors have answered the questions and improved the manuscript.
As I submitted, 'The English language and style are fine/minor spell check required' means the authors should carefully check the format/spell in the manuscript again.
Some examples:
- In line 130, 2.7.1, Please check the spell of 'ABTS' or 'ABTS.+', and please keep it constant in the manuscript.
- In Table 1, please check the grid in the table.
- Please re-organize the figures as some figure captions were missing.
