Instructions to the authors

Authors who plan to present oral presentations or posters at the 69th Scientific Conference with international participation “Food Science, Engineering and Technologies 2022”, should prepare their manuscripts following the instructions below.


Content of the manuscripts

It is strongly recommended that non-English speakers edit their manuscripts in English before submitting for review. It is recommended that the manuscripts be edited by native English speakers or by English language philologists who are also familiar with the specifics of the technical terminology of the article. Manuscripts that do not have a good enough language to meet English standards will be rejected before the evaluation stage for their scientific value. Manuscripts should be worded in .docx format, Times New Roman and should be worded as follows:


First (Title) page - with single column text. The title page includes:

  • Title - up to 12 words, Bold, Arial 16.

  • Author (s) first name (s) Italic, Times New Roman 10.

  • Last name (s) Regular, Times New Roman 10.

  • Institutions in which the authors work – Regular. Affiliations of authors should be typed in 9-point Times. They should be preceded by a numerical superscript corresponding to the same superscript after the name of the author concerned. Please ensure that affiliations are as full and complete as possible and include the country.

  • Full details of the correspondence author (name, scientific position, scientific title, department, faculty / division, institution, postal address, telephone, mobile, fax, e-mail), Regular.

  • Abstract - up to 200 words, Regular, no references used.

  • Keywords - up to 7 words, Regular.

  • List of abbreviations - Regular.


Main text - formed in two columns with Times New Roman 10 font, Regular.

The main text of the article includes:

1. Introduction. It should include a review of the available literature, a conclusion from the literature review, the purpose and objectives of the study.

2. Materials and Methods or Methodology.

3. Results.

4. Discussion.

5. Acknowledgments.

6. References used.

Presentation of scientific data - text, tables and figures in one or two columns page layout depending on their size, Times New Roman 9, Regular.

Scientific data provided include:

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

2. Figures - graphs, photos, diagrams etc. The description of the figures must be written below them.

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

Title and name(s) of the author(s) - The title should accurately reflect the content of the article. It should make it easier to find the article through indexes developed by secondary literature.

A good title should:

1) clearly identify the relevance of the study;

2) show the goals of the study;

3) give an idea of the important concepts used in the text in advance.

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

Many readers read the titles in the contents of a journal before deciding whether to refer to a summary or to read an article. This is why the title should stimulate the reader's interest. Highly specific and narrowly specialized titles, with words that are only understood by a specific small group of experts, are usually overlooked by readers. In addition, literary search engines ignore titles that are incomprehensible to most readers and are only clear to very 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 in the title, the trivial names of compounds, plant and animal species and cereals should be used. If a crop or micro-organism is not indicated by its trivial name, the use of a scientific name (genus and species in Latin) is permissible.If there is only one author or if all authors have the same address, then this information should not be repeated and listed as many times as the co-authors of the article.


The reports presented in Bulgarian must be accompanied by an abstract in English. When reading an abstract one should find it easy to determine the scientific value of the report (scientific communication) and decide whether to read it further or not. In many cases most people read the abstract and not the whole report. In this way the abstract has a dual function: providing information to those who will read the whole report and to those who will not read the entire article. It should be written after the writing of the article is completed and must be fully consistent with the claims made in the publication. To some extent the abstract may replicate expressions of 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 comprehensible in itself. It should include:

  • the grounds for carrying out the work, including the rationale or definition of the research.

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

  • a brief description of the methods used. If the article examines method (s) of analysis the abstract describes 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.

The abstract should pay 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 abstract should be specific, avoiding the use of general statements.The abstract should not exceed 200 words and should not be divided into paragraphs. It should not include references to bibliographies, figures or tables, equations, formulas, obscure abbreviations, and acronyms. Scientific names should be included in the abstract where frequently used names are firstly mentioned.Authors should prepare an English translation of the abstract that will be published at the beginning of the article.

List of abbreviations

All abbreviations used in the text must be written in their full names



Under the abstract authors must provide a list of up to 7 manuscript keywords. Keywords should include the topic studied and the specific techniques used. Keywords should be informative, not referenced in the body text. It is recommended that the keywords do not repeat terms from the title.


The article should begin by clearly identifying the subject of the study. The authors should indicate their working hypothesis or clearly define the problem they are trying to solve by conducting this experiment. The reader is guided by the scientific results of previous concepts and studies which are reported in brief form. References to the literature used should be limited to information that is essential to guide the reader. Most readers do not need long literary reviews, especially old hypotheses and models if more recent ones are available, in order to be convinced of the importance of the study. The purpose of the introduction is to provide sufficient prior information to enable the reader to understand and evaluate the results of this study without having to refer to previous publications on the topic.

The introduction should be brief and include:

1. a summary of the problem justifying the research or hypothesis on which it is based.

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

3. an explanation of the common approaches and objectives. This section may indicate the means by which the problem has been investigated, especially if the methods of investigation are new.

Materials and methods

The editorial board of the conference will allow the publication of manuscripts based on experimental data study or theoretical analysis provided that acceptable results are obtained. The purpose of this section is to give sufficient details about the analytical procedures and the setting of the experience so that a competent scientist can repeat the experiment. Authors should provide information on relevant technical specifications (technological documentation), quantities, formulations and sources or suppliers of the materials used as well as methods of sample preparation.

If a commercially available product is used, the name and address of the manufacturer must be given in brackets. If necessary, the chemical and physical properties of the reagents must be listed. Preference should be given to the chemical and not the trade names of the materials used. All biological test items not mentioned in the abstract must be accurately 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 are only described by their names quoting their authors in brackets with reference to the bibliography. If the method used is modified, a brief description of the modification should be made unless the change is trivial. Give details of unusual experimental formulations of the experiment or of the statistical methods used to process the data. This section may be organized in chronological order according to the sequence of analytical techniques used or otherwise. This section may include tables, graphs, diagrams and figures.



This section should avoid verbal retelling of facts that are already clear from the review of attached charts 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 the Results section should provide clarity on the understanding of 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 findings should be noted. When only a few measurements are presented they should be treated descriptively in the text. Repeated measurements must be presented in tables or graphs.

The result of each experiment should be clarified in the text paying attention to the specifics, e.g: "... one quantity is greater than the other, the result is linear over its entire range or the optimal value is established, etc." .Finally, the results must be linked. Often this is the reason for the Results section to be combined with the Discussion section. The Editorial Board does not recommend a similar combination of the two sections.



The Discussion section provides a scientific discussion and interpretation of the data presented in the Results section with particular attention to the problem or hypothesis set out in the introduction. A good discussion in the Discussion section should include:

1. principles, relations and generalizations that can be supported by the results obtained;

2. placing emphasis on results and conclusions that are confirmed or not confirmed by the work of other researchers;

3. practical applications and theoretical impacts;

4. conclusions summarizing the evidence on a case-by-case basis

In the Discussion section, if it is not combined with the Results section, no summary of the results obtained should 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 the Introduction section or presented as a work objective. The research should relate to previous scientific developments 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 replaced or revised with newer one.Speculation is encouraged but must be reasonably used and firmly based on observations and tested. Where the results differ from previously published similar results for unexplained reasons possible explanations should not be generated. The issues at stake must be discussed clearly and fairly (with an appropriate dose of impartiality).



The manuscripts must by all means include the Conclusion section. The authors should include some significant conclusions drawn from the results of the study. These conclusions must be carefully worded so that they can be easily identified.



In this section authors can express their appreciation to other scientific institutions, companies, government bodies or people who have supported or contributed financially or otherwise to the research presented in the manuscript. The acknowledgements should be typed in 9-point Times, without title.

Arrange the list of references in alphabetical order according to the authors' surnames. Two or more articles by the same author (s) must be arranged in chronological order; two or more articles of the same year must be denoted by the letters a, b, c, etc. All articles by one author must precede his articles in which he is the leading author of collectives. The cited sources with the same leading author must be arranged in alphabetical order by the surnames of the subsequent co-authors and thereafter followed by the year when the names are repeated verbatim.

Do not capitalize the title of the article except the first letters of the first names and the first letter of the words of the title (if the text is in English). The titles of periodicals (scientific journals) and books should not be abbreviated but should be completely written down.


Measuring units

The SI system is accepted as a mandatory standard. If any non-standard abbreviations are to be used they must be defined at their first occurrence in the text.

Tables, figures and graphs

Mentioning of tables, graphs and figures in the text should be in sequential order.

Figures come in two types: graphs or photos. The photos should be in good contrast and with proper focus throughout the shooting. In addition, as figures in the form of ordinary linear graphs can also be treated: complex formulas, flow charts, metabolic charts and large or complex tables. The figures are reproduced photographically and almost always at a reduced size from the original provided by the authors. It is therefore necessary for authors to plan as much reduction as possible so that the figures are reduced to fit into a single column of the journal (69 mm). All letters, numbers and symbols must be large enough in the original to be at least 1.5 mm high after reduction. Use standard characters such as a, b, c, d, f.

Preparation for publication

The author proof-reading pages will be sent to the authors for a final review before the article is published. Changes other than the correction of typographical errors will only be made at the discretion of the Editor-in-Chief. After the manuscripts have been corrected they must be returned to the editorial board as soon as possible. Otherwise the editor reserves the right to correct the proofs individually and to send in this kind of material for publication.
