Round 1

Reviewer 1 Report

Please review the publication for grammatical and spelling errors and inaccuracies. Such as:

Line 176: "whey protein denaturationl"... and for the WPD rate, although   it was stated that there was a difference in the study, no statistical difference was shown in Table 1.

Reviewer 2 Report

1. This article is helpful to developing nations, especially those who require longer transportation times yet lack complete cold-chain transportation. Unfortunately, the sterilization method mentioned in this article had already been applied, hence the article won't be considered particularly inventive.

2. Steam will be produced during the Direct Steam Injection Instantaneous Ultra-High Temperature (DSI-IUHT) Sterilization; kindly specify the improvement.

3. The results indicated that sterilization had a significant impact on milk, but they did not adequately illustrate the necessity of using this system.

4. It can be seen from the results of Figures 1, 2, and 3 that there were variations following sterilization, but the findings were not discussed in the discussion.

5. There should be more discussion of odor-active coumpounds.
