Instructions to authors

Authors who plan to present oral presentations or posters at the 70th  Scientific Conference with international participation “Food Science, Engineering and Technologies 2023”, should prepare their manuscripts following the instructions below.

Contents of the manuscripts

Non-English-speaking authors are strongly advised to edit their manuscripts in English before submission for peer review. It is recommended that manuscripts be edited by scholars who speak native English or by philologists who are experts in English and at the same time familiar with the specific technical terminology of the article. Manuscripts that do not have sufficiently good language to meet English standards will be rejected before the stage of assessment for scientific merit. Manuscripts should be formatted as a Word Document, saved in .docx format, in Times New Roman font and formatted as follows:

Title - up to 12 words, Bold (Half an evening), in script Arial 16.

Иthe author(s) - Italic (Italics mine), with font Times New Roman 10.

Last name of author(s) - Regular (Ordinary), with font Times New Roman 10.

Institutions where the authors work - Regular, с Times New Roman font 9, numbered with the same superscript corresponding with the name, detailed, country.

Author's full details for correspondence (name, scientific position, scientific title, department, faculty/department, institution, postal address, telephone, mobile, fax, e-mail), Regular.

Abstract - up to 200 words, Regular, not including bibliography.

Keywords - up to 7 words, Regular.

List of abbreviations - Regular.

Introduction. To include a review of the available literature, conclusion of the literature review, aim and objectives of the study.

Materials and Methods or Methodology.




References (Bibliography).

Scientific data presented include:

Tables. The description of the tables should be written above them.

Figures - graphs, pictures (photographs), diagrams, etc. The name of the figures should be written below them.

Figures and tables should be placed in their respective places in the text.

The title should accurately reflect the content of the article. It should make it easy to find the article using indexes developed from secondary literature sources.

A good title should:

1) clearly identify the significance of the study;

2) to indicate the objectives of the study;

3) to give a preliminary idea of the important and very important concepts used in the text.

The meaning and order of the words in the title are also important! The title should be useful. It is in itself a kind of label for the article. Headline terms should be limited to those words that provide significant information about the content of the article!

Many readers read the headlines in a magazine's table of contents before deciding whether to turn to an abstract or read an article. Therefore, the headline should pique the reader's interest. Highly specific and highly specialised titles, with words that are only understandable to a specific small group of specialists, are usually passed over by readers. In addition, literary search engines ignore titles that are incomprehensible to the majority of readers and clear to only a few people.

The title should never contain abbreviations, chemical formulas or proprietary names! For this reason, authors should avoid using unusual or outdated terminology.

To save space, the trivial names of chemical compounds, plant and animal species and crops should be used in the title. If a plant crop or micro-organism is not referred to by its trivial name, it is acceptable to use the scientific name (genus and species in Latin).

If there is only one author or if all authors have the same address, this information should not be repeated and listed as many times as there are co-authors of the article.

When reading the abstract, it should be easy to determine the scientific value of the paper (scientific communication) and decide whether to read it further or not. In many cases, most people read Summarynot the whole report. In this way, the summary has the dual function of providing information to those who will read the whole report, and to those who will not read the whole paper. It must be written after the writing of the article is complete and must be completely consistent with the claims made in the publication. To some extent, the abstract may repeat phrases from the article, but since it is usually read immediately before the introduction or other main sections, these repetitions should not be annoying. On the other hand, the abstract should be completely self-explanatory. It should include:

  • the reason for doing the work, including the rationale or definition of the research.

  • justification of the objectives covered and the subject of the publication.

  • a brief description of the methods used. If the article discusses method(s) of analysis, the abstract shall describe the basic principles, scope and degree of accuracy of the new method(s).

  • results (trends of the more important results of the study are presented).

  • conclusions or inferences.

The summary should draw attention to new elements, observations and numerical data. It should be informative. Expressions such as 'is discussed' and 'is described' should be used infrequently. The summary should be specific, avoiding the use of general statements.

Summary must not exceed 200 words and should not be divided into paragraphs. It should not include references to the bibliography, figures or tables, equations, formulae, obscure abbreviations and acronyms. Scientific names should be included in the abstract where common names are mentioned for the first time.

Authors should prepare an English translation of the abstract to be published at the beginning of the article.

All abbreviations used in the text must be spelled out in full.

Below the abstract, authors should provide a list of up to 7 key words from the manuscript. The keywords should include the topic studied and the special techniques used. Keywords should be informative without reference in the main text. It is recommended that the keywords do not repeat terms from the title.

The paper should begin by clearly identifying the object of the study. Authors should state their working hypothesis or clearly define the research problem they aim to solve by conducting the present experiment. The reader is oriented to the scientific results of previous concepts and studies, which are reported in the form of a brief reference. References to the literature used should be limited to information that is essential to guide the reader. Most readers do not need lengthy literature reviews, especially of old hypotheses and models if newer ones are available, to be convinced of the relevance of the research. The purpose of the introduction is to provide sufficient background information to enable the reader to understand and evaluate the results of the present study without the need to refer to previous publications on the subject.

The introduction should be brief and include:

a brief statement of the problem that justifies the research or hypothesis on which it is based.

the results of other scientific publications that need to be challenged or further developed.

explanation of general approaches and objectives. This section may indicate the means by which the problem was investigated especially if the research methods are new.

The Editorial Board of the conference will accept for publication manuscripts that are based on Experimental investigation of data or theoretical analysis, provided that acceptable results are obtained. The purpose of this section is to give sufficient detail of the analytical procedures, the set-up of the experiment, so that a competent scientist can repeat the experiment. The authors should provide information on the relevant technical specifications (process documentation), quantities, formulations and sources or suppliers of the materials used, and sample preparation methods.

If a commercially available product is used, the name and address of the manufacturer should be given in brackets. If necessary, the relevant chemical and physical properties of the reagents should be listed. It is preferable to give the chemical rather than the trade names of the materials used. All biological test objects not mentioned in the summary should be precisely identified by genus, species, variety, classification or special characteristics. The methods of analysis used in the study should be cited with reference(s) if possible. If the analytical techniques used are widely known, they should be described by their names only, with the authors cited in parentheses, and reference made to the bibliography. If the method used has been modified, a brief description of the modification to be applied shall be given unless the change is trivial. Give details of any unusual experimental set-up of the experiment or statistical methods used to process the data. This section may be organized chronologically, according to the sequence of analytical techniques used, or otherwise. This section may include tables, graphs, charts and figures.

This section should avoid a verbal restatement of facts that are already clear from a review of the attached graphs or tables. If the tables and figures are well thought out and constructed, they will show the reader both the results of the experiment and the experimental setup.

The tables, graphs and other illustrations in section Results should provide clarity in understanding the representative data obtained from the experiments. The data included in the illustrations and tables should not be discussed in detail in the text, but important and significant findings and discoveries should be noted. Where only a few measurements are presented, they should be treated descriptively in the text. Repeated measurements should be presented in tables or graphs.

The result of each experiment should be clarified in the text by addressing the specifics, e.g., "... one quantity is greater than the other, the result is linear over its range, or an optimal value has been found, etc.".

Finally, the results must be linked together. Often, this is the reason section Results be combined with a section Discussion. The Editorial Board does not recommend such a combination of the two sections.

In the section Discussion a scientific discussion and interpretation of the findings presented in section Results data, paying particular attention to the problem or hypothesis stated in the introduction. A good discussion in part Discussion should contain:

  • principles, relationships and generalizations that can be supported by the results obtained;

  • Placing emphasis on results and conclusions that are confirmed or not confirmed by the work of other researchers;

  • practical applications and theoretical impacts;

  • conclusions summarising the evidence in each case.

In the section Discussionif it is not combined with a section Results, generalizations of the results should not be made, but their relevance to science and practice should be discussed. It should be clear how the results offer a solution to the problems identified in section Introduction or presented as the purpose of the work. The research should be related to previous research papers along with an explanation of how and why it differs or agrees with them. References should be limited to those that are most relevant to the purpose of the discussion. Older knowledge should not be cited if it has been superseded or revised by more recent ones.

Speculation is encouraged, but it must be used judiciously and be firmly based on observation and subject to testing. When results differ from previously published similar results for unexplained reasons, possible explanations should not arise. Controversial issues should be discussed clearly and fairly (with an appropriate degree of impartiality).

Manuscripts must include a section Conclusion. The authors should include some significant conclusions that emerge from the results obtained in the study. These conclusions should be carefully worded so that they can be readily identified.

In this section, the authors may wish to acknowledge other scientific institutions, companies, government bodies or individuals who have contributed to or supported financially or otherwise the research presented in the manuscriptwithout title, in font Times 9.

Arrange the list of literature used alphabetically according to the last names of the authors. Two or more articles by the same author(s) should be arranged in chronological order; two or more articles from the same year should be identified by the letters a, b, cetc. All articles by an author should precede his/her articles in which he/she is the lead author. The ordering of references cited with the same lead author should be organized alphabetically by the last names of subsequent co-authors and then by year when names are repeated verbatim.

Do not capitalize the title of the article, except for the first letters of proper names and the first letter of the title words (if the text is in English). Titles of periodicals (scientific journals) and books should not be abbreviated but should be spelled out in full.

Units of measurement

The SI system has been adopted as the mandatory standard. If any non-standard abbreviations are to be used, they must be defined when first encountered in the text.

Tables, figures and graphs

References to tables, graphs and figures in the text should be in sequential order.

Figures are of two types: graphics or pictures (photographs). Photographs must have good contrast and proper focus throughout the entire shooting. In addition, the following may be treated as figures in the form of conventional line graphs: complex formulae, flow charts, metabolic schemes and large or complex tables.Figures are reproduced photographically and almost always at a reduced size from the original provided by the authors. It is therefore necessary for the authors to plan as much reduction as possible so that the figures are reduced to fit in one column of the journal (69 mm). All letters, figures and symbols should be large enough in the original to be at least 1.5 mm high after their reduction. Use standard characters such as: a, b, c, d, f.

 Preparation for publication

The proofreading pages will be sent to the authors for a final check before publication. Changes other than correction of typographical errors will be allowed only at the discretion of the Editor-in-Chief. Once corrected, manuscripts should be returned to the editors as soon as possible. Otherwise, the editor reserves the right to correct the proofs independently and send the material as is for publication.
