  • Wrote the paper (only authors who made a major contribution).
  • Had primary responsibility for final content.
  • Other (use only the mentioned categories are not applicable; describe briefly).
  • All authors have read and approved the final manuscript. For single-authored research papers and reviews, please state: The sole author is responsible for all parts of the manuscript.

For example: H. mozaffari, A. Rahmati, and P. Hashemi designed research; H. Mozaffari and B. Mohammadi conducted research; P. Khosravi analyzed data; and A. Rahmati, P. Hashemi and B. Mohammadi wrote the paper. H. Mozaffari had primary responsibility for final content. All authors read and approved the final manuscript.  


JNFS uses the Council of Science Editors (CSE) style of references with the name/year system. All references cited in the text should be listed (double spaced) at the end of the manuscript in alphabetical order under the last name of the first author. If there are more than six authors, list the first six authors and use ‘et al.’ Articles ‘in press’ may be included, but the journal that has accepted them must be stated. Personal communications should be avoided. Journal titles should be abbreviated according to the Index Medicus. References in the text should be noted with the authors’  last names and publication year within parentheses. If there are two authors, both should be named (e.g., Agar and Douglas 1955); if an article with more than two authors is cited, only the first author’s name plus ‘et al.’ should be written (e.g., Komor et al. 1979). If there is more than one reference by the same author or team of authors in the same year, then a, b, c, etc., should be added to the year, both in the text and the list of references. When styling references, the following format should be followed, consider the following example:

Journal article: Brain WR. 1958. The physiological basis of consciousness. A critical review. Brain 2 (4):426‐455.

Book: Kuhlenbeck H. 1954. The human diencephalon.A summary of development, structure, function and pathology. Basel: Karger.

Chapter in book:Teuber HL. 1964. The riddle of frontal lobe function in man. In: Warren T, Akert CH, editors. The frontal and granular cortex and behavior. New York: McGraw-Hill, pp 252­‐271

 Each illustration should have a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep the illustration texts to minimum but explain all symbols and abbreviations used. Figures should be included only if they improve the manuscript.


Tables should be consecutively numbered in accordance with their appearance in the text. Footnotes should be placed below the table body. Tables should be sparing in the use and the data presented in them should not be described elsewhere in the manuscript.


 Abbreviations that are unavoidable in the abstract must be defined at their first mention there. Also, abbreviations should be explained throughout the manuscript.

Review articles

This section should be prepared according to one of the following styles:

Systematic reviews: This kind of manuscripts should be in form of meta-analysis, meta-synthesis, or without statistical analysis. JNFS encourages authors to conduct and report systematic reviews and meta-analyses based on PRISMA guideline. These manuscripts contain original articles’ parts. They should contain 2500-7000 words.

Moher D, Liberati A, Tetzlaff J, Altman DG, The PRISMA Group (2009) Preferred Reporting Items for Systematic Reviews and Meta-Analyses: The PRISMA Statement. PLoS Med 6(7): e1000097. doi:10.1371/journal.pmed.1000097

Narrative reviews

This kind of manuscripts should be written by researchers who are expert in the related field. Different parts of such articles include abstract, introduction, discussion, and conclusion. This type of study should contain at least 25 references and the range of 3000-10000 words including the references and captions.

Short communications

It can be in the form of original article, systematic review, or an ongoing research which reports its interesting findings. The parts in this type of articles are similar to those of original one except that ‘Materials and methods’ section should have not any subtitle. These kinds of manuscripts are smaller and thus are prepared in minimum 1500 and maximum 2500 words.

Letter to the editor

It should be about criticism of previous articles in this journal or the others, criticism or review over books, analysis of a related topic with food quality and control. These manuscripts need no structure.

Case reports

This kind of manuscript should include abstract, keywords, introduction, case report, discussion, conclusion, conflicts of interest, acknowledgment, and references. Case report should have 1500-2500 words. The title should include the words ‘case report’ as well as a description of the reported phenomenon (e.g., reporting of new and rare food borne pathogen). Three to five key words should be provided.


These manuscripts need no structure and do not have abstract. But, their total words should be 2000 at maximum including references, while references should not exceed more than 10.

Conflict of interests

Submitting a manuscript must be accompanied with a statement from the authors disclosing all financial and personal relationships that might bias their work, if there is any. Besides, they are requested to clarify whether impending conflicts do or do not exist. A separate page should cover this proclamation and if there are further details, they could be mentioned in a covering letter. If an organization encompasses any financial interest in the outcome of the study, authors are appealed to provide a declaration that has full access to all data in the study and accept complete responsibility for the integrity of data and the accuracy of data analysis

Page charges

There is no charge for publication in the JNFS. The journal does not  charge  for APCs.


Four reprints will be provided free of charge.


Peer review process flowchart in JNFS is shown in the following. Manuscripts are sent sequentially to the executive manager.  Executive Manager initially evaluates the manuscript and sends it back to the corresponding author or forwards it to the editor-in-chief. After initial evaluation, the manuscript is sent to an expert for plagiarism evaluation. Editor-in-chief solicits reviewers (typically two external reviews) to review the manuscript. The reviewers’ evaluations are compiled by the editor-in-chief and sent to the corresponding author. Decision on acceptance/ rejection is made usually within six weeks after manuscript reception. The Editor-in-chief informs authors whether the text should be revised or is rejected. Minor revisions are expected to be returned within four weeks of decision; major revisions within three months. Manuscripts not revised within these time periods are subject to withdrawal from consideration for publication unless the authors can provide extenuating circumstances. The final decision on manuscript's reconsideration will be made by Editor-in-chief. However, if authors dispute a decision and document good reasons that why a manuscript should be reconsidered, there will be a rebuttal process. In this case, authors should sent their documents to the editor-in- chief.
