Physicochemical Properties of Enzymatically Modified Starches
Round 1
Reviewer 1 Report
The peer-reviewed article is important from the point of view of research on the rheological properties of starch in terms of texture determination. It also provides important data that can be used in practice for food production. Nevertheless, I believe that the article requires more care in the preparation of the manuscript as the processing of the results is quite chaotic.
1. Abstract section, line 9 please specify the abbreviation GSET, it is difficult to guess what to refer to it.
2. Material and methods section, paragraph on statistical analysis is missing 3. Table started from line 221 seems like a ghost
4. Table 1a, as described, should present the results obtained for the experiments carried out at two temperatures, 30 and 40 degrees Celsius, while the presented results are for 30
5. Similarly, in table 1b where, according to the description, there should be a variant of 50 degrees and it is 40.
6. I am also concerned about the correctness of the results in Table 2a for the parameter t0 in the case of corn, the standard deviation values ​​are greater than the mean value. How is it possible ?

- Abstract section, line 9 please specify the abbreviation GSET, it is difficult to guess what to refer to it.
Response to the first revewer:
Throughout it is GSET and stands for germinated sorghum extract treatment
- Material and methods section, paragraph on statistical analysis is missing
2.10. Statistical Analysis
Measurements were done in triplicate and the data were analyzed using ANOVA. A factorial design was applied to test for the effects of GC and GZ on starch. Duncan’s multiple range test was applied to compare means at p ≤ 0.05 using the PASW® Statistics 18 software (SPSS Inc., Hong Kong, China P.R.).
- Table started from line 221 seems like a ghost
Table was fixed
- Table 1a, as described, should present the results obtained for the experiments carried out at two temperatures, 30 and 40 degrees Celsius, while the presented results are for 30
Tables were fixed
- Similarly, in table 1b where, according to the description, there should be a variant of 50 degrees and it is 40.
It was not possible to combine the tables because it became very larg.
- I am also concerned about the correctness of the results in Table 2a for the parameter t0in the case of corn, the standard deviation values ​​are greater than the mean value. How is it possible ?
It was a typo and was fixed
Reviewer 2 Report
The manuscript “Physiochemical properties of enzymatically treated modified starch” represent an effort for the determination of some properties of chickpea, corn, Turkish bean, and sweet potato starch in the native, annealed, and annealed with enzyme treatment forms.

- Discussion of results should be improved by comparison with the relevant literature.
- Please, consider revising Figure 2 a, b c, d in a more correct way, since they are containing to many figures inside and provide a detailed description in the caption.
- Table 4 contains some typing errors, please correct.
- Some data fitting in Table 4, reports low R2 (e.g., 0.85, 0.88). Please, provide some comments on these results.
- Results of water holding capacity should be provided and accompanied by a proper statistical analysis to show if the reported differences among data are significant.

Table 5: in the caption replace otatostarch with potato starch.
- Germinated sorghum extract was indicated into the manuscript by different abbreviations: GSET (abstract), GSE in figure 1, figure 2, Table 5, GSETT in paragraph 3.2 and 3.4. Please correct using the same abbreviation or indicate if different meanings are related to different abbreviations.
- Paragraph 2.10: what is the meaning of GC and GZ?
- Check the references in the text, which should be reported in square brackets (e.g., line 524, pag 20)
- Please, avoid the use of different symbols (e.g., τ and σ, R2 and r2,or GSET and GSE) and avoid the continuous introduction of new abbreviations throughout the manuscript (e.g., SS or SR).
- In paragraph 3.2 authors mentioned that annealing and GSETT reduced the WHC of S.P.S.(PAG. 18, lines 475-476), while in the Table 5, statistical results showed that only the value obtained by GSETT for S.P.S. is significantly different from that of native S.P.S. Could the authors better clarify this aspect?
