Potential Valorization of Banana Production Waste in Developing Countries: Bio-Engineering Aspects
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe submitted manuscript is a very interesting review about banana byproducts utilization. Provides very interesting information on the examined issue. However, I have some suggestions for improvement and overall clarity.
L33-35: in which country or region? Probably you mean worlwide.
L36-36: why this abnormal situation is happening? Is there any explanation? If yes, please mention it, it could be interesting for the readers.
Table 2: refer what %, you mean. Probably % w/w, also add some standard deviations of your values. If these values are mean values based on data previously presented in the literature, I suggest to present them in the form of intervals (ranging from the lowest to the highest value).
Moreover, a standard deviation with a 0.00 value is not possible. Also Iron (Fe) is missing standard deviation value.
Some potential suggestions:
Usage of banana flower in the agriculture and food industry.
I suggest a minor revision before acceptance.

Reviewer 2 Report
Comments and Suggestions for AuthorsBrief summary:
The authors present the review paper "Potential Valorization of Banana Production Waste in Developing Countries: Bio-Engineering Aspects". The article highlights the advantages of using banana by-products (BPs) to address problems in developing countries. The authors begin by explaining the global importance of banana harvests and why banana waste is a concern. They discuss diverse banana by-products such as peels, leaves, pseudostems, etc., and their industrial applications as fuels, medicine, biosorbents, and other uses. The review also explores the use of banana by-products as fibers, for example, in fabrics, paper, and other applications. The authors goal is to generate ideas that motivate the research of new knowledge that will inspire the innovation of new technologies.
In addition, the use of banana fibers for agro-industrial applications is very important, the paper could add more information about this. Overall, this paper presents relevant information that could inspire new technologies. In developing countries, this could be a source of new jobs, addressing economic issues in these nations.
Specific comments:
Here are some observations that need attention:
Line 42. The acronym BPs (by-products) is defined in the Abstract, but mentioning it again here could help readers identify it more easily.
52-54. The article referenced in this phrase does not discuss carbohydrates from bananas. The phrase was extracted from the article, but it cites other articles dating back to 2006 (see https://www.sciencedirect.com/science/article/pii/S0308814617308191?via%3Dihub). I suggest updating this reference with more recent sources. If discussing carbohydrates from bananas specifically, include relevant references; otherwise, clarify that these are properties of carbohydrates in general.
57. I strongly recommend improving the image resolution and changing the symbology used, as it's difficult to identify the areas. Using colors could facilitate reading.
67. What does the 'm' at the end of the data refer to?
110-129. More references about cosmetic use are required. Please consult additional sources for these claims.
150. Using schemes to explain the method is a good tool for reader orientation. However, these schemes require more explanation or better justification for their use.
232. Table 3 shows good data about phosphorylase from unripe bananas, but more explanation about its implications and importance is necessary.
238. The authors state that reducing sugars can be a carbon source for Lactobacillus delbrueckii, but more text about the importance of this is necessary. For example, discuss the industrial impact of this microbial species and why using banana by-products as a carbon source is important.
309. Fuel application is interesting data. I recommend adding more waste-valorization technologies, for example, microbial fuel cells.
311. I suggest placing the reference number at the end of the sentence.
320. Replace "Brazin" with "Brazil".
323. References are necessary for this claim. Please add the relevant references.
328. Please replace "garlic" with "gallic".
410-412. Data and references for this claim are required. Please add data and references at the end of the sentences.
Regarding the use of banana by-products as fibers, I suggest incorporating a table that presents their mechanical properties.
