Guidelines for authors

Journal of Food & Biofunction (JFB) is a peer-reviewed open-access international journal that invites original research, reviews, short reports, and commentaries focusing on research in food science, nutrition, and health.

JFB aims to publish novel, cutting-edge, original research focusing on food, functional foods, bioactive ingredients, and their mechanisms of action, as well as their roles in health nutrients and disease prevention.

The journal operates a double-blind peer-review policy. Every article will be freely and indefinitely accessible online. Articles are published as soon as possible after acceptance and in 3 issues of a volume per year.

Types of articles

The Journal of Food & Biofunction (JFB) accepts the following contributions:

Research articles 

The length of research papers is not limited. However, in the best interests of the readers and the dissemination of the work, we strongly advise the authors to be concise.

Review articles

Review articles on subjects of current perspectives and reader interest are welcomed and encouraged. Reviews should be brief, not exceeding 4 to 20 printed pages. Authors are requested to write review articles prior consult with the Editor-In-Chief and submit an outline to the journal editorial office before preparing their manuscripts.

Short communications 

Short Communications have the following soft limits. The manuscript should ideally contain no more than 5-7 Figures/Tables, it must be within 2 to 5 printed pages, including the title page, all sections of the manuscript (including the references), and Figure/Table legends. The abstract should be limited to 200 words.

Peer review

All papers are subject to double binder peer review. The Journal has an identified panel of expert reviewers. However, the editor may seek additional reviewers by requesting it from the corresponding authors if the topic of a paper requires.

Article file format

Authors are requested to use the Microsoft Word template with Palatino Linotype theme font to prepare their article. Margin:1 cm on all sides, Font size: 12, spacing: double.

Manuscript style

Title page

The title needs to be clear and precise. The title page must list the full title, short title of up to 100 characters and the names and affiliations of all authors must be listed on the title page. Author (s) must provide the detailed address, including email, telephone and fax, of the author who will check the proofs.

Please include a Cover Letter at the beginning of the title page. Please explain why your manuscript should be published in the JFB in your covering letter, along with a declaration of any potential competing interests. The authors must confirm that all authors have read and approved the manuscript for submission and the manuscript has not been published, or submitted for publication elsewhere.

Abstract

The abstract should not exceed 250 words for all articles. An abstract is a concise summary of the whole paper, which is not just the conclusion and is comprehensible without referencing to the rest of the paper. It cannot provide any citation to other published work.

Keywords

Use 6-10 keywords that describe your paper best.

Introduction

A concise introduction is required of the background to the subject, its significance and its relationship to earlier works, with references.

Materials and methods 

Materials and methods should be presented with clarity and detail. Authors who purchased/collected the plant materials from companies/any authorized organization, must mention the voucher specimen number for future works/references. In the case of commercial extract, the extraction procedure from the organism of origin must be specified. State the methods and important techniques in this section. The physical and spectroscopic data for new compounds must be comprehensive. Illustrate these with figures or tables where necessary but keep these to a minimum. Authors are requested to submit their additional documents as a supplementary file (word/excel/Pdf format).

Units of measurement 

JFB uses the SI (International Units) system for most units of measurement.

Some exceptions are listed below. Commonly used empirical units are permissible.

Never use a plural form for the symbols; 30 kgs would be incorrect. Give a space between measurement and number (for example, 25 mm) but no space between number and degree sign (for example, 25oC) and % sign (for example, 35%). The range is formatted as 0.3-0.9 g.

In the GC-MS analysis, please provide the RI or KI index of the identified compounds in the article table. The reported RI or KI data (for comparing) of the identified compounds on the same column improves the quality of the data presentation, but is not mandatory.

Results and discussion 

Results and discussion can be presented separately or combined in one section. Results should include the findings of the study including, if appropriate, results of statistical analysis which must be included either in the text or as tables and figures. For research articles, discussion section should discuss the implications of the findings in the context of existing research and highlight the limitations of the study.

Conclusions

State the conclusions clearly in a few sentences that you have drawn from the findings and provide key recommendations. Do not include references in the conclusion section.

Tables and figures

You must number the tables and figures (e.g., table 1, table 2, table 3; fig.1, fig. 2, fig. 3) and reference them in the text. Place the tables at the end of the main text. Tables should be in an editable format, and not embedded as an image file. You must include figure titles and legends in the manuscript file—they should not be included in the image file.

Sections and subsections

Distribute your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering).

Assure the following
