line 46 "remarkable" - change word

The aim of the work was not clearly articulated, there is indeed a mention of what was not done/found in the available literature, but this is not the aim

very well planned scientific experiment. Chart 6 - very innovative graphic form presenting research results

Reviewer 2 Report

Comments and Suggestions for Authors

General comments

The manuscript entitled "Effects of Microwave Treatment on Physicochemical 2 Attributes, Structural Analysis, and Digestive Characteristics of 3 Pea Starch-Tea Polyphenols Complexes" shows very interesting results on the effect of using microwave radiation on mixtures of pea starch and polyphenolic compounds. 

Specific comments

Authors must cite literature references reporting the effect of using microwaves on polyphenol molecules. Wouldn't just microwave radiation, at the frequency used in the study, cause degradation of polyphenols? 

Line 58

Define the meaning of DIVR before the acronym. 

Section 3.1. 3.1 Complexation Index of PS-TPs

In this section, authors must cite literature references that indicate the use of microwave radiation in the formation of complexes in starch molecules.

Lines 290 – 298

Although the argument is correct, the writing is somewhat confusing and/or monotonous. The authors should improve the presentation of the text. For example: there is no point in reporting all the same values ​​in the text that were already reported in table 2. 

Lines 301 - 304

The authors must try to find a hypothesis for the different behavior at the frequency of  200 W compared to the trend of increasing particle size for the other frequencies. 

Figure 2.

The authors must to split the x-rays spectra of the particle size distribution in two figures. 

Table 3

Although the change caused by the use of microwave radiation in the thermal properties of the systems was clearly observable, the effect of the frequency change was relatively small on these same properties. The authors must present a hypothesis and/or other citations from the scientific literature for this behavior. 

Table 4 and Figure 5a are repeating themselves. Authors must choose one of the ways to present the results only.
