Reviewer 2 Report
The study described in the paper is interesting, but the paper should be further clarified and improved. The major corrections are needed for the manuscript, and minor corrections are also listed.
1) Abstract:
Page 1, line 6 - Use "compounds" once in this sentence.
Page 1, line 7 and 8 - Correct capital letter for "Total".
Page 1, line 15 - Define "TCC" or specify without abbreviations.
Page 1, line 17 - Correct "glucozide".
Page 1, line 18 - Perhaps, express anthocyanin content per g, as other contents.
Page 1, line 18 - Correct "among others, Eucalyptol was among the most abundant".

2) Introduction:
For references 4 and 6, more adequate needs to be found (or at least, add references supporting better these claims).
Page 2, line 6 - Correct "thermos-labile".
Page 2, line 23 - Correct "physical" to "physical properties".
3) Materials and methods:
"Shrinkage determination" is missed.
Delete "2.2. Methods" (since "methods" are also determination of phenolic, flavonoids,…), and correct "2.2.1. Drying Process" to "2.2. Drying process", etc.
Page 3 - Correct "Hue angl" to "Hue angle" in the formula (2).
Page 3, line 14 - Define the moisture ratio abbreviation, i.e. add "(MR)".

Page 3, line 28 - Correct "following the following".
Page 3, title of table 1 - Correct "Used".
Page 3, Table 1 - Specify Models formulas as equations "MR=...", and in the text enumerate the constants of the models and use "t" for time, as in Table 2. In the "Approximation of Diffusion", is the "t" a constant (as value is calculated in the table 5)? It is not a constant in the literature: https://doi.org/10.1080/19476337.2015.1136843, http://dx.doi.org/10.33448/rsd-v9i4.2887 and http://dx.doi.org/10.1590/1807-1929/agriambi.v26n1p67-74.
Page 3, line 38 - Perhaps, "50 times the weight of the sample (1:50)," could be more clear with "…g of dried material per …g of distilled water".
Page 3, title of 2.4. section - "Rehydration process" is more appropriate. Modeling of rehydration kinetics is in section 2.5.
Page 4, line 4 - Correct "rehydration rate".
Page 4, line 6 - Correct "2.2.".
Page 4, line 7 - In the text present uniformly dry matter content ("dm", "DM", "dry matter. ", etc).
Page 4, line 11 - "The experimental results of rehydration of tamarillo dried in a convection oven (40, 50, 60, 70, 80 and 90°C)" - This is not clear as rehydration was done at 25°C.
Page 4 - Formula (7) and (9) of SSE are different.
Page 4, title of Table 2 - Correct "Used", "dehydration " and "Birinci derece" in the Table 2.
Page 4, title of Table 2 - For Weibull model add "]".
Page 4, Table 2 - Same letters for constants should be used as in the Table 6. Also, in the text enumerate the constants of the models (in the page 4, line 10).
Page 4, line 27 and 28 - Correct "Samples" and "gr".
Page 4, line 33 - Check the unit "mg/g".
Page 5, line 10 - Is the method "Zhishen et al. 1999" (Zhishen J, Mengcheng T and Jianming W. 1999. The determination of flavonoid contents in mulberry and their scavenging effects on superoxide radicals. Food Chemistry, 64, 555-559.) more appropriate?
Page 5, line 14 - Correct "Ayang".
Page 5, line 23 - Correct the unit "mg g-1" to "mg/g".
Page 5, line 42 - Check DPPH concentration.
Page 6, line 5 - Correct "2 Mm 94%" to "94% 2 mM ".
Page 6, line 28 - Correct "2.3.2.9."
4) Results and discussion:
Page 6, Table 3 - Correct "B".
Page 7, line 1 and 2 - Correct "(a)" and "(b)".
Page 7, line 10 - Clarify, i.e. in which term the previous studies pointed out the same thoughts and support the present study.
Page 7, Figure 1 - Delete title on the chart "shrinkage". Add all statistical analysis on the Figure 1.
Page 8 - Correct the Table number; "Table 5" to "Table 4", etc. in the paper.
Page 9 - Correct the Figure number; "Figure 3" to "Figure 4".
Page 9, line 4 - Correct "dehydration" to "rehydration".
Page 9, line 4 - Is the Peleg or Proposed model the best-suited for rehydration curves?
Page 9, line 8 - Clarification for "The longest time.....105 minutes", and then "at 500 W with approximate 110 minutes".
Page 10, Table 6 - Correct "DK" in the Table 6.
Page 10, line 4 - Perhaps, correct "capacity and activity" to "properties".
Page 10, line 5 - Define "TCC".
Page 10, line 16 and 17 - Check the cited information in the references 73 and 76.
Page 10, line 19, 20 and 21 - Correct the text according to the Table 7.
Page 11, Table 8 - Add "*There is no statistical difference between the averages..."
Page 11, line 8 - Check the cited information in the reference 65.
Page 11, Table 9 - Perhaps, express anthocyanin content per g, as other contents.
Page 12, title of Table 9 - Correct "Dried" to "dried" and "Bold" for some compounds.
5) Reference:
The references 8 and 56 are the same references. Check are the References in the list described as required.

Thank you also for your comments and I hope that you shall like my research paper.
I wish you good time.
Reviewer 2 Report
The study described in the paper is interesting, but minor corrections are needed.
1) Abstract
Page 1, line 12 and 13 - Perhaps, it is better "Total phenolics, total anthocyanins, total flavonoids, total carotenoids,..."
Page 1, line 26 - Delete "capacity", since content of antioxidant compounds was mostly higher in FD and antioxidant activity was higher for tree tomato fruits dried using the microwaves.
2) Materials and methods
Page 5, line 133 - The constants g and h, are not constant of the models in Table 1, and constant n and y are missed.
Use same constant of the model for same model in the Table 1 and Table 4, as well as in the Table 2 and Table 5:
- In the Table 1 for Page model k and y are constants, and in Table 4 for Page model k and n are constants;
- In the Table 1 for Logarithmic model a, k and c are constants, and in Table 4 for Logarithmic model a, b and k are constants;
- In the Table 2 for Peleg model k1 and k2 are constants, and in Table 5 for Peleg model a and b are constants.
Page 5, line 145, 146 and 147 - Correct "MWry matter".
Page 4 and 5, formula (7), (9) and (10) - Add "1/2" (i.e. "root") at the end of the formula (10). In the formula (9) "1/N" is entered in the formula (9), while "1/N" is not entered in the formula (7). This should be check.
3) Results and discussion:
Page 10, line 282 - Correct references 64 to 63, and 65 to 64.
Page 10, line 292 and 293 - Delete "and the figure 4" and "respectively".
Page 12, line 311 - Correct the Title of Figure 4"Rehydration curve of microwaves dried tree tomato fruits" to "Rehydration curve of microwaves dried and freeze dried tree tomato fruits".
Page 14, line 373 - Correct "Table 10" to "Table 9".
Page 11, line 306 - Correct "Table 6" to "Table 5".
Page 13, line 338 - Correct "Table 8" to "Table 7".
Page 13, line 346 - Correct "Table 8" to "Table 7".
Page 15 and 16, Table 9 - Correct "Nd" to "nd" at several places.
