  • How to search effectively

What are Boolean operators?

The three main Boolean operators are AND, OR, and NOT. Each instructs a database how search terms need to be combined, and that lets us configure searches to find more precise and relevant results. View and download our tips for effective searching or learn more.

Is it possible to filter for human studies on FSTA?

Yes! The filter is specific to the platform you are searching FSTA on, so click on the name of the platform you use to find information for EBSCOhost, Ovid or Web of Science.

Why are patents important for research?

While most academic research in food and nutrition science is published in scholarly journals, research conducted in industry might be shared with the world only when its intellectual property can be protected, through patents. University researchers also sometimes patent methods and technologies. Patent documents are sometimes the only way for researchers to get access to this information. Learn more

How can I find the full text of food science and technology patents?

Once you have the title of a patent, you can usually find its full text if you type it, inside quotation marks, on the free websites Espacenet or Google Patents. Learn more about finding patents and getting their full text.

What is phrase searching?

Phrase searching means typing two or more words - words that, used together, capture a concept - inside quotation marks in a search. It can be very useful for narrowing a search if the phrase you are using is really a phrase, but if your words do not need to be a phrase you will miss relevant results. Learn more

What is adjacency searching?

The phrase adjacency searching is often used synonymously with proximity searching. This kind of search uses a proximity operator to stipulate that search terms be no more than a stated number of words from each other in a field, like the title or abstract, of a record. Learn more

What is proximity searching?

Proximity searching lets you determine how close one search term must be to another in order for the results to be useful for you. You do this by inserting a proximity operator between your search terms. Learn more about this kind of searching and how useful it can be here.

What is a proximity operator?

Proximity operators are what you type between your search terms to run a proximity search. Exactly what you type is platform dependent. What they all have in common, though, is that they let you include a number to indicate the maximum distance the search terms can be separated from each other. Find what a platform's operator is in its help section. Learn more about proximity operators and how to use them.

What are stopwords?

Stopwords are words that are not counted as words for a database’s search rules. They are usually common words like and, as, for, from, is, of, that, the, this, to, was, and were. Find out more

What is peer review?

A peer reviewed journal article has been read and approved for publication by experts in the field.

As a student researcher who is building knowledge but is not yet an expert, it gives you the reassurance that the article you are reading is based on solid research, though there still may be arguments over its conclusions, and it still needs to be critically appraised. The process works like this:

  • An author submits a paper to a journal
  • The journal sends it out to experts in the exact area of the paper's research to review
  • They provide comments to a senior editor to make a decision on whether to accept or reject the paper
  • The reviewers should comment on features such as the robustness of the methodology, and whether the research has been designed, conducted and analysed in a way which is coherent, valid and ethical

The most common forms of peer review involve keeping identities of reviewers and/or authors secret, at least until the peer review process is over. These are known as Single Blind (where the author does not know the names of the reviewers), and Double Blind (where all author information is removed from a paper, and neither reviewers or authors can be identified). Learn more about peer review from an author's perspective

How can I learn more about how to use FSTA?

We have a range of resources available, such as downloadable guides, videos and more, depending on the platform you use to access FSTA. Take a look at our training hubs for EBSCOhost, Ovid and Web of Science.

  • Carrying out literature reviews

What is literature searching?

Literature searching is the task of finding relevant information on a topic from the available research literature. Literature searches range from short fact-finding missions to comprehensive and lengthy funded systematic reviews. Or, you may want to establish through a literature review that no one has already done the research you are conducting. If so, a comprehensive search is essential to be sure that this is true.

Whatever the scale, the aim of literature searches is to gain knowledge and aid decision-making. They are embedded in the scientific discovery process. Literature searching is a vital component of what is called "evidence-based practice", where decisions are based on the best available evidence. Learn more

What is a literature review?

A literature review is a critical assessment of the literature relating to a particular topic or subject. It aims to be systematic, comprehensive and reproducible. The goal is to identify, evaluate and synthesise the existing body of evidence that has been produced by other researchers with as little bias as possible. Learn more about what is involved in a literature review.

How do I carry out a literature search?

Good searching takes place in three broad stages: planning, searching, and follow up.

In the planning stage, you line up tools to optimize organization and think about where you can and should search. You also begin to define your search question and translate it into a search strategy. This merges into the search stage, where you will try out your search strategy in different databases and refine, refine, refine! You will collect records along the way, but you don't need to get the full text of these articles until you start the follow-up stage where you screen the records, first cursorily, then carefully.

Following this procedure for your searching helps ensure that you are actually catching the research most relevant to your question. Learn more

What is critical appraisal?

Critical appraisal is the process of systematically evaluating and assessing the research you have found in order to determine its quality and validity. Critical appraisal is essential to evidence based practice. Learn more

Are there any guides that can help me use the right terminology when writing literature reviews?

The Academic Phrasebank (J. Morley, University of Manchester) is a useful resource for academic writing and is freely available here. It’s not specific to literature reviews, but will definitely be helpful.

  • Carrying out systematic reviews

What is a systematic review?

A systematic review is a type of research study where all the studies that have been done on a question to date are located and analysed to find a comprehensive answer to the question. A systematic review must capture all the relevant literature on a question so that its conclusion is based on all available evidence. The study will be done in stages:

  • In stage one, the question, which must be answerable, is framed.
  • Stage two is a comprehensive literature search to identify relevant studies.
  • In stage three the identified literature’s quality is scrutinised and decisions made on whether or not to include each article in the review.
  • In stage four the evidence is summarised and, if the review includes a meta-analysis, the data extracted
  • In the final stage, findings are interpreted.

Some reviews also state what degree of confidence can be placed on that answer, using the GRADE scale. By going through these steps, a systematic review provides a broad evidence base on which to make decisions about medical interventions, regulatory policy, safety, or whatever question is analysed. By documenting each step explicitly, the review is not only reproducible, but can be updated as more evidence on the question is generated. Learn more about systematic reviews and the software tools to support your systematic review process.

  • Getting published

Why is it important to publish research in a journal rather than self-publish?

Although it is very easy to self-publish your own work through a range of platforms such as websites, blogs, and social media accounts, publishing research and scholarly work in a highly regarded journal is a key part of academic careers. There are several key benefits to publishing research in journals including discoverability, contributing to the records of research in the field, the benefits of peer review, dissemination and impact, career advancement and preventing duplication of effort. Learn more

How can I decide where to publish?

Our Publishing Guide has been developed to help authors navigate the process of selecting appropriate journals and understand the range of factors which might influence the decisions of where to submit. The guide explains a range of topics including the benefits of publishing in journals, different open access models, publishing ethics, and more.

The FSTA Journal Recommendation Service (JRS) is an online tool designed for researchers and authors working in the sciences of food and health. Powered by FSTA's coverage list of over 1000 quality-checked journals from publishers worldwide, the JRS matches your title and abstract to potentials journals, or you can browse using keywords. It lets you filter results by impact factor, open access policies, and more. Try the JRS

Why should I pay attention to a journal's “Aims and Scope”?

The Aims and Scope of a journal provides the key information about it - why it exists, what it aims to achieve, and what it is looking for from submissions. This information can usually be found on the journal website.

Understanding the Aims and Scope of a journal is critical to getting past the first hurdle of editorial review, and on to the peer review process. Failure to properly fit the subject scope of the journal or to help it further its editorial aims are common reasons for immediate rejection of submissions. It is important to make sure that you clearly understand it by investigating the journal website and reading sample articles, especially from recent issues. Key information to look for includes statements about subject or geographic scope, readership, and novelty or contributions. Make notes of all these aspects for each of your journals of interest.

For the paper you are currently writing, or looking to submit, consider how well your methods, sample populations and conclusions relate to the aims, scopes and readership of a journal, to understand whether it is suitable. Learn more

What can citation metrics tell me about a journal?

Citation metrics are an average of citations received by a journal, within a particular time frame. These can give us some helpful insights into the standards and history of journals, and may be an important factor in deciding where to submit your paper.

It may be assumed that a high citation metric has editorial processes of a high standard, but what it really means is that a journal is receiving a lot of citations and may be worth investigating further. The metrics themselves can be subject to a great degree of change. Just one highly cited paper can make a significant difference to the metrics of a journal year-on-year, so looking at a single metric for one year is not enough to determine the overall stature of a journal. By looking into their citation profile and metrics over the previous years you will get a better idea of the consistency of how a journal is used by the field.

It is worth noting that the use of citation metrics as a method for assessing the quality or value of research, journals, and especially individual researchers, has been a fiercely debated, controversial issue. Learn more

What are altmetrics and how are they different to citation metrics?

Alternative metrics, or altmetrics, monitor attention to individual articles and research outputs, providing almost instantaneous updates on the mentions of papers from a wide range of sources. These include traditional citations, public policy documents, mainstream media newspapers, blogs and websites, online reference managers, post publication review sites, Wikipedia, and social media platforms.

While traditional citation metrics are calculated by assessing the average number of citations received by a journal within a particular timeframe, altmetrics can give you even more insight into how beneficial a journal can be for you and your work. Altmetrics can be a valuable resource when determining where to publish your work. They are also a powerful tool for helping you know who is discussing your research and what they are saying about it, helping you enhance, increase, and further the impact and presence of your paper. Learn more

How do I prepare to submit my paper to a journal?

Each journal will provide instructions for authors on how to submit a paper, including the structure, formatting, word counts, and much more. Some journals may even provide a set of templates for manuscripts which can greatly help for structuring and formatting your papers and can be a helpful tool where available. Failure to comply with instructions for authors sits alongside aims and scope as the top reason articles are rejected from journals. Read more about how to ensure you comply with the journal’s requirements and what to expect when submitting to a journal.

If I am asked to include a cover letter when I submit my manuscript, what should the letter include?

If you need to include a cover letter with your submission, you should address the editor by formal name (e.g. Dear Professor Name---) and include the name of the journal. In the letter, explain why your article is suitable for that journal and how your paper will contribute to furthering its aims & scope. Pitch the value of your article, describing the main theme, the contribution your paper makes to existing knowledge, and its relationship to any relevant articles published in the journal. You should not repeat the abstract in the letter. Learn more about what to include in your cover letter.

What is peer review?

Peer review is a process by which manuscripts are selected for publication in journals.

There are many different ways in which the process is conducted, but the core principle is that a submission is read by experts in the field, who provide comments to a senior editor to make a decision on whether to accept or reject the paper. The reviewers should comment on features such as the robustness of the methodology, and whether the research has been designed, conducted and analysed in a way which is coherent, valid and ethical.

The most common forms of peer review involve keeping identities of reviewers and/or authors secret, at least until the peer review process is over. These are known as Single Blind (where the author does not know the names of the reviewers), and Double Blind (where all author information is removed from a paper, and neither reviewers or authors can be identified).

  • Predatory journals and ethical concerns

What is a predatory journal?

Basically, a predatory journal is one that will charge money to publish any research article with no peer review or other quality checks, so the literature published in them is unreliable, and sometimes completely fake.

There is no definitive criteria for what makes a journal "predatory", but areas such as intention, impact, monetary gain, quality, status, and reputation are all factors in how they can be assessed. Learn more

How does FSTA identify and exclude predatory journals?

In addition to ensuring new journals include sufficient content within the scope of FSTA’s subject area coverage, our editorial team of experts in the sciences of food and health conduct a thorough evaluation of each new journal against a checklist of criteria relating to potentially predatory or unethical publishing practices. This enables us to identify and exclude publishers and journals that may be using such practices. Our checklist covers 60 measures across several diverse areas. Learn more
