Aims and Scope

The Journal of Oleo Science publishes peer reviewed,
Open Access articles on basic and applied research into fats
and oils. Basic research topics include the chemistry, biochemistry and science of fats and oils, such as related foodproducts, detergents, natural products, petroleum products,
lipids and related proteins and sugars. The journal encourages the submission of manuscripts that combine chemistry
and/or biochemistry with biological/sensory/nutritional/toxicological evaluation related to agriculture and/or food.
Published by the Japan Oil Chemists Society, the Journalof Oleo Science publishes high-quality articles twelve times ayear in print and continuously online. The journal consists ofthe following sections:a）Oils & Fatsb）Detergents, Surfactants, Interface & Colloidc）Biochemistry & Biotechnologyd）Medical Chemistrye）
Nutrition, Health Function & Food Sciencef）Chemistry & Organic Synthesisg）Essential Oils & Natural Productsh）Cosmetic Sciencei）General Subjects

Manuscript Types

The journal welcomes 7 manuscript types, all of which undergo rigorous peer review.

Regular Papers
Regular Papers are reports of unpublished and original research that describe valuable conclusions or findings.

Notes
Notes are shorter than Regular Papers and contain important information about new devices and/or new ideas, including hypothetical commentary that is useful for researchers
working in the field of oleo science. The goal of this article
type is to encourage critical evaluation, idiosyncratic view
points and challenges to current dogma. However, the ideas
should be based on sound data without excessive speculation.
Notes should be 3,200 words or less.

Rapid Papers
Rapid Papers are preliminary reports containing importantdiscoveries or conclusions that warrant precedence over other manuscript types. Rapid Papers should be 4,900 words orless including references, tables and figures. The reports maylater be expanded and published as a Regular Paper. A short
explanation of the urgency should be included with the initialsubmission.

Reviews
Reviews summarize a particular aspect of oleo science.
Most Reviews are invited, but unsolicited contributions arealso welcome. Please send inquiries with an outline to the Editor-in-Chief before submitting a manuscript.

Commentary and Perspectives
Commentary and Perspectives introduce hot topics in oleo
science. Most Commentary and Perspective articles are invited by the organizers of the annual Japan Oil Chemists Society（JOCS）or other scientific meetings, but unsolicited contributions are also welcome. Please send inquires with an
outline to the Editor-in-Chief before submitting a manuscript.

Editorials
Editorials are written by the Editor-in-Chief, Editorial
Board members or Guest Editors-in-Chief, and are used todescribe new policies, introduce new Editorial Board members, and provide commentary.

Special Issues
The journal welcomes proposals for Special Issues, which
are usually composed of four or more articles focusing on aparticular topic. Proposals can be from JOCS members, theEditorial Board, Associate Editors or Advisory Board members. The proposer should contact the Editor-in-Chief directly, and may be appointed as a Guest Editor. Special Issue
manuscripts are peer reviewed and the publication and page
charges must be paid. The proceedings of a scientific meetingcan be considered for a Special Issue.

Journal & Ethics Policies

The Journal of Oleo Science upholds the highest standards in scholarly publishing.
Before submitting a manuscript to the journal, authors
must ensure that they have read and complied with the journal s policies. The journal reserves the right to reject without
review, or retract, any manuscript that the Editor believes
may not comply with these policies.
The responsibilities of the journal s authors, editors, reviewers and publisher regarding research and publication
ethics are described in full below.
Submission to the journal implies that the manuscript has
not been previously published（in part or in whole, in any language）, is not in press, and is not under consideration for
publication elsewhere.
Authors must inform the editors if any related manuscripts
are under consideration, in press or published elsewhere.
If authors choose to submit their manuscript elsewhere before a final decision has been made on its suitability for publication in the Journal of Oleo Science, they should first withdraw it from the journal.
Various reporting guidelines have been developed for different study designs. Authors are encouraged to follow published standard reporting guidelines for the study discipline.
• CONSORT for randomized clinical trials• CARE for case reports• STROBE for observational studies• PRISMA for systematic reviews and meta-analyses• STARD for studies of diagnostic accuracy• SAGER for reporting of sex and gender information
Please access https://www.equator-network.org/ to find theguideline that is appropriate for your study.
It is extremely important that when you complete any Reporting Guideline checklist that you consider amending yourmanuscript to ensure your article addresses all relevant reporting criteria issues delineated in the appropriate reporting
checklist. The purpose of a reporting guideline is to guide you
in improving the reporting standard of your manuscript. The
objective is not to solely complete the reporting checklist, but
to use the checklist itself in the writing of your manuscript.
Taking the time to ensure your manuscript meets these basic
reporting needs will greatly improve your manuscript, while
also potentially enhancing its chances for eventual publication.

Submission
The Journal of Oleo Science welcomes manuscript submissions from authors based anywhere in the world.
Submission of a manuscript to the journal implies that all
authors have approved it, warrant it is factual, have agreed toits submission, and have the right to publish it.

Originality
Submission to the journal implies that the manuscript is(2)

original work. The journal may use Crossref s Similarity
Check plagiarism software to screen manuscripts for unoriginal content. By submitting a manuscript to the journal, authors agree to this screening. Any manuscript with an unacceptable level of unoriginal material may be rejected or
retracted at the Editors discretion.

Preprints
To support the wide dissemination of research, the journal
encourages authors to post their research manuscripts oncommunity-recognized preprint servers, either before oralongside submission to the journal. This policy applies only
to the original version of a manuscript that describes primaryresearch. Any version of a manuscript that has been revised
in response to reviewers comments, accepted for publicationor published in the journal should not be posted on a preprint
server. Instead, forward links to the published manuscript
may be posted on the preprint server. Authors should retain
copyright in their work when posting to a preprint server.
Authors may deposit an initial draft of their manuscript in a
preprint service such as Jxiv, ChemRxiv, bioRxiv, arXiv, or theapplicable repository for their discipline before the manuscript is accepted for publication in the Journal of Oleo Science. Authors may revise the preprint version of their manuscript up until a final acceptance decision has been issued.
Please note any use of a preprint server in the cover letterand include a link to the preprint, and as appropriate, state
how the manuscript has been adjusted/updated between deposition and submission. All other prior/redundant publication is forbidden. Upon publication in the Journal of Oleo
Science, authors should add a link from the preprint to the
published article via the Digital Object Identifier（DOI）. Some
preprint servers, including Jxiv, ChemRxiv and bioRxiv, add
this link for authors automatically after publication.

Authorship
Submission to the journal implies that all authors have seen
and approved the author list. Changes to the author list after
manuscript submission – such as the insertion or removal of
author names, or a rearrangement of author order – must be
approved by all authors and the editor.
Authors are encouraged to consider the Council of Science
Editors（CSE）principles governing authorship. According to
the CSE guidelines（and references therein）, each author is
expected have made substantial contributions to the conception or design of the work; or the acquisition, analysis or interpretation of data; or have drafted the work or substantively
revised it. Authors have also agreed to be held accountable
for their own contributions to the work; can identify which
co-authors are responsible for other parts of the work; haveconfidence in the integrity of the work; and have reviewed
and approved the final manuscript and any resubmissions.

Instructions to Authors

Contributors who do not qualify for authorship may be included in the Acknowledgements section instead.

Use of Artificial Intelligence（AI）-Assisted Tools/
Technologies
In consonance with the COPE s position statement, WAME s
recommendations, and ICMJE s Recommendation, the Journal of Oleo Science does not allow artificial intelligence（AI）-assisted tools/technologies such as Large Language Models（LLMs）, chatbots, or image creators to be listed as author or
co-author. As described in the ICMJE, those tools cannot be
responsible for the accuracy, integrity, and originality of thework, thus they do not meet the ICMJE s criteria for authorship listed above.
The authors（humans）are fully responsible for any materials of the submitted work, including the use of AI-assisted
tools or technologies. Authors should carefully review andedit the result because AI can generate authoritative-sounding output that can be incorrect, incomplete, or biased. Authors should not list AI and AI-assisted technologies as an author or co-author, nor cite AI as an author. Authors（humans）
are also responsible for plagiarism including in text and AIproduced images.
Authors must disclose, upon submission and in the Methods（or similar section）, any use of AI-assisted tools or technologies in the writing of a manuscript, production of images
or graphical elements of the paper, or in the collection andanalysis of data.

Image integrity
Authors may digitally manipulate or process images, but
only if the adjustments are kept to a minimum, are applied tothe entire image, meet community standards, and are clearly
described in the manuscript. All images in a manuscript must
accurately reflect the original data on which they are based.
Authors must not move, remove, add or enhance individual
parts of an image. The editors reserve the right to request
original, unprocessed images from the authors. Failure to provide requested images may result in a manuscript being rejected or retracted.

Reproducing copyrighted material
If a manuscript includes material that is not under the authors own copyright, the authors must obtain permission
from the copyright holder（s）to reproduce it.
If a manuscript includes previously published material, theauthors must obtain permission from the copyright owners
and the publisher of the original work to reproduce it. The
authors must cite the original work in their manuscript.
Copies of all reproduction permissions must be included
with the manuscript when it is first submitted.

Availability of data and materials
Authors must disclose the source of publicly available data
and materials, such as public repositories or commercial manufacturers, by including accession numbers or company details in their manuscript, as appropriate.
Authors may make their own data and materials available
as Supporting Information, or by linking from their manuscript to relevant community-recognized public databases ordigital repositories. All data sets must be made available infull to the editors and reviewers during the peer review process, and must be made publicly available by the date of publication. Authors commit to preserving their data sets for atleast three years from the date of publication in the journal.
The journal encourages authors to grant reasonable requests from colleagues to share any data, materials and experimental protocols described in their manuscript.

Animal/human experimentation
Authors of manuscripts describing experiments involving
humans or materials derived from humans must demonstratethat the work was carried out in accordance with the principles embodied in the Declaration of Helsinki, its revisions,and any guidelines approved by the authors institutions.
Where relevant, the authors must include a statement in theirmanuscript that describes the procedures for obtaining informed consent from participants regarding participation in
the research and publication of the research.
Authors of manuscripts describing experiments involving
animals or materials derived from animals must demonstratethat the work was carried out in accordance with the guidelines approved by the authors institution（s）.

Author competing interests and conflicts of interest
In the interests of transparency, the journal requires all authors to declare any competing or conflicts of interest in relation to their submitted manuscript. A conflict of interest exists when there are actual, perceived or potential circumstancesthat could influence an author s ability to conduct or reportresearch impartially. Potential conflicts include（but are notlimited to）competing commercial or financial interests, commercial affiliations, consulting roles, or ownership of stock orequity.
Authors should list all funding sources for their work in the
Acknowledgements section of their manuscript.

Confidentiality
The journal maintains the confidentiality of all unpublishedmanuscripts. By submitting their manuscript to the journal,
the authors warrant that they will keep all correspondence
about their manuscript（from the Editorial Office, editors andreviewers）
strictly confidential.

Self-archiving（green Open Access）policy
Self-archiving enables authors to deposit a copy of their(3)Instructions to Authors

manuscript in an online repository. The Journal of Oleo Science encourages authors of original research manuscripts to
upload their article to an institutional or public repository immediately after publication in the journal.

Long-term digital archiving
J-STAGE preserves its full digital library, including the
Journal of Oleo Science, with Portico in a dark archive（see
https://www.portico.org/publishers/jstage/）. In the event thatthe material becomes unavailable at J-STAGE, it will be released and made available by Portico.

Peer Review Process

Editorial and peer review process
The journal undertakes single-anonymized peer review.
When a manuscript is submitted to the journal, it is assigned
to the Editor-in-Chief, who performs initial screening. Manuscripts that do not fit the journal s scope or are not deemedsuitable for publication are rejected without review. The remaining manuscripts are assigned to an Executive Editor who
assigns two reviewers to assess each manuscript. Reviewers
are selected based on their expertise, reputation and previous
ex- perience as peer reviewers. The deadline for submissionof the reviewers reports varies by article type.
Upon receipt of the two reviewers reports, the Executive
Editor makes the first decision on the manuscript. If the decision is to request revision of the manuscript, authors have 50
days to resubmit their revised manuscript. Revised manuscripts submitted after this deadline may be treated as new
submissions. The Executive Editor may send revised manuscripts to peer reviewers for their feedback or may use his or
her own judgement to assess how closely the authors havefollowed the Executive Editor s and the reviewers commentson the original manuscript.
The Executive Editor then makes a recommendation to the
Editor-in-Chief on the manuscript suitability for publication.
The Editor-in-Chief is responsible for making the final decision on each manuscript.
The members of the Editorial Board act in advisory roles,
providing feedback as reviewers and making suggestions toimprove the journal. In cases where the Editor-in-Chief is anauthor on a manuscript submitted to the journal, a member ofthe Editorial Board is responsible for making the final decision on the manuscript s suitability for publication in the journal.

Use of Artificial Intelligence（AI）-Assisted Tools/
Technologies
Reviewers are prohibited from uploading the manuscript tosoftware or AI-assisted tools/technologies where the confidentiality is not assured. It is required to disclose to the journal if any AI-assisted tools or technologies are used to facilitate the review. Reviewers should be aware that AI cangenerate authoritative-sounding output that can be incorrect,(4)

incomplete, or biased.

Reviewer selection, timing and suggestions
Reviewers are selected without regard to geography andneed not belong to the journal s Editorial Board. Reviewers
are selected based on their expertise in the field, reputation,
recommendation by others, and/or previous experience as
peer reviewers for the journal.
Reviewers are invited within 2 weeks of an article being
submitted. Reviewers are asked to submit their first review
within 4 weeks of accepting the invitation to review. Reviewers who anticipate any delays should inform the Editorial Office as soon as possible.
When submitting a manuscript to the journal, authors may
suggest reviewers that they would like included in or excluded from the peer review process. The Editor may consider
these suggestions but is under no obligation to follow them.
The selection, invitation and assignment of peer reviewers is
at the Executive Editor s sole discretion.

Reviewer reports
It is the journal s policy to transmit reviewers comments tothe authors in their original form. However, the journal reserves the right to edit reviewers comments, without consulting the reviewers, if they contain offensive language, confidential information or recommendations for publication.

Acceptance criteria
If a manuscript satisfies the journal s requirements and represents a significant contribution to the published literature,
the Editor may recommend acceptance for publication in thejournal.
Articles in the Journal of Oleo Science must be:• within the subject area of the journal s scope• novel and original• descriptions of technically rigorous research• of high interest to the journal s audience• important additions to the field.
If a manuscript does not meet the journal s requirements
for acceptance or revision, the Executive Editor may recommend rejection.

Editorial independence
As the journal owner, the Japan Oil Chemists Society（JOCS）has granted the journal s Editorial Board complete
and sole responsibility for all editorial decisions. JOCS will not
become involved in editorial decisions, except in cases of afundamental breakdown of process.
Editorial decisions are based only on a manuscript s scientific merit and are kept completely separate from the journal sother interests. The authors ability to pay any publication
charges has no bearing on whether a manuscript is acceptedInstructions to Authors

for publication in the journal.

Appeals
Authors who believe that an editorial decision has been
made in error may lodge an appeal with the Editorial Office.
Appeals are only considered if the authors provide detailed
evidence of a misunderstanding or mistake by a reviewer or
editor. Appeals are considered carefully by the Editor-inChief, whose decision is final. The guidelines of the Committee on Publication Ethics（ COPE）are followed where andwhen relevant.

Confidentiality in peer review
The journal maintains the confidentiality of all unpublishedmanuscripts. Editors will not:a）disclose a reviewer s identity unless the reviewer makesa reasonable request for such disclosureb）discuss the manuscript or its contents with anyone notdirectly involved with the manuscript or its peer reviewc）use any data or information from the manuscript in theirown work or publicationsd）use information obtained from the peer review process
to provide an advantage to themselves or anyone else, or
to disadvantage any individual or organization.

Conflicts of interest in peer review
A conflict of interest exists when there are actual, perceived or potential circumstances that could influence an editor s ability to act impartially when assessing a manuscript.
Such circumstances might include having a personal or
professional relationship with an author, working on the same
topic or in direct competition with an author, or having a financial stake in the work or its publication, or having seen
previous versions of the manuscript.
Members of the journal s Editorial Board undertake to declare any conflicts of interest when handling manuscripts. An
editor who declares a conflict of interest is unassigned fromthe manuscript in question and is replaced by a new editor.
Editors try to avoid conflicts of interest when inviting reviewers, but it is not always possible to identify potential bias.
Reviewers are asked to declare any conflicts of interest to the
Editor, who will determine the best course of action.

Errata and retractions
The journal recognizes the importance of maintaining the
integrity of published literature.
A published article that contains an error may be corrected
through the publication of an Erratum. Errata describe errorsthat significantly affect the scientific integrity of a publication,
the reputation of the authors, or the journal itself. Authors
who wish to correct a published article should contact the editor who handled their manuscript or the Editorial Office withfull details of the error（s）and their requested changes. In
cases where coauthors disagree over a correction, the Editor-

in-Chief may consult the Editorial Board or external peer reviewers for advice. If a Correction is published, any dissenting
authors will be noted in the text.
A published article that contains invalid or unreliable results or conclusions, has been published elsewhere, or has infringed codes of conduct（covering research or publication
ethics）
may be retracted. Individuals who believe that a published article should be retracted are encouraged to contact
the journal s Editorial Office with full details of their concerns. The Editor-in-Chief will investigate further and contact
the authors of the published article for their response. In cases where co-authors disagree over a retraction, the Editor-inChief may consult the Editorial Board or external peer reviewers for advice. If a Retraction is published, any dissenting
authors will be noted in the text.
The decision to publish Errata or Retractions is made at
the sole discretion of the Editor-in-Chief.

Editors as authors in the journal
Any member of the journal s Editorial Board, including the
Editor-in-Chief who is an author on a submitted manuscript is
excluded from the peer review process. Within the journal s
online manuscript submission and tracking system, they will
be able to see their manuscript as an author but not as an editor, thereby maintaining the confidentiality of peer review.
A manuscript authored by an editor of the Journal of Oleo
Science is subject to the same high standards of peer review
and editorial decision making as any manuscript consideredby the journal.

Responding to potential ethical breaches
The journal will respond to allegations of ethical breaches
by following its own policies and, where possible, the guidelines of COPE.

Reviewer confidentiality
As part of their responsibilities, reviewers agree to maintainthe confidentiality of unpublished manuscripts at all times. By
accepting the invitation to review a manuscript, reviewers
agree not to:1）
disclose their role in reviewing the manuscript2）
reveal their identity to any of the authors of the manuscript
3）
discuss the manuscript or its contents with anyone notdirectly involved in the review process4）
involve anyone else in the review（for example, a postdoc
or PhD student）
without first requesting permission fromthe Editor
5）
use any data or information from the manuscript in theirown work or publications
6）
use information obtained from the peer review process
to provide an advantage to themselves or anyone else, or
to disadvantage any individual or organization.

Tables, figures and reaction schemes
Tables and figures should be essential to the communication of the results and not repeat the same information. Tableand figures, including photos, reaction schemes, and complex
equations should be provided on separate sheets and numbered consecutively with Arabic numerals, e.g. Table 1, Fig. 1,
and Scheme 1 in numerical order.
A title should be given to each table and it must use capitalletters. Explanatory material and footnotes should be typed
below the table and should be designated with superscript
letters, such as a）or b）. Units of measurement should be included with numerical values at the top of columns. Avoid detailed explanations of the experimental conditions used toobtain the data shown in tables（which should be included inother sections as relevant）.
Figures should have a resolution of 600 dpi or higher. If the
figure will need be reduced in size for the print/PDF version,
the author should consider line thickness and the size of theletters and symbols. Each figure, illustration or photographshould be placed on a separate page with consecutive numbers, as in Fig. 1, Fig. 2. For figures to be printed in color, authors should indicate so in the margin.
Captions for figures, photographs and tables should be provided on a separate page. Captions for figures should be formatted as follows（pay attention to the use of periods）: Fig.
1. Effect of ... oils. .
When submitting photographs（black and white）for publication, provide high-contrast prints that are of single- or double-column width and therefore will not have to be reduced
when printed. Avoid submitting color figures that will be
printed in black and white.

Contributions
Authors should include an Author Contributions section in
their manuscript, as a separate subheading just before Acknowledgements（or References if there are no acknowledgements）. This text should describe the specific contributionsof each author, designated by initials, to the submitted work.

Examples of such author designations could include: designed
research; performed research; contributed analytic tools; analyzed data; or wrote the manuscript. An author may have contributed to more than one aspect of the work, and more than
one author may have contributed to the same aspect of thework. Failure to include this information in a submitted manuscript will cause it to be returned to the author（s）
with a request to add the paragraph.

Supporting Information
Supporting information adds, but is not essential, to a reader s understanding of a manuscript. Authors are encouraged
to submit supplementary material for online-only publication.
Supplementary material may comprise data, text, audio or
movie files, and is published online alongside the accepted
manuscript.
As supplementary material is peer-reviewed, authors must
submit it in its final form as part of their manuscript submission. After a manuscript has been accepted for publication,authors may not make any changes to the supplementary material. Supporting Information is available free of charge via
the internet at https://www.jstage.jst.go.jp/browse/jos/.
If the supporting information is large memory [tables（datasets）, graphs, photos, videos, software, programs（ sourcecode）, protocols et al］
is also available by J-STAGE Data.

Accepted Manuscripts

Authors are required to submit the electronic revised manuscripts of MS-Word or PDF files which contain the final corrected version of the article. The Editorial Office will liaise asnecessary during this process.
Manuscripts that are accepted for publication are copyedited and typeset by the journal s production team before publication. The journal is published twelve times per year / continuously online. All communication regarding accepted
manuscripts is with the corresponding author.

ProofsAuthors may examine proofs until the deadline date, which
is usually 48 hours after receipt of proofs, and will be charged
for changes other than correction of printer s errors. Authors
should return corrections（if any）
only via e-mail.
Printer s errors after publication will be corrected upon request from authors.
Page proofs are sent to the corresponding author, whoshould check and return them within 48 hours. Only essential
corrections to typesetting errors or omissions are accepted;
excessive changes are not permitted at the proofing stage.

Reprints
Order forms for reprints are sent with the proofs to the corresponding author and should be returned with the proofs.
