Biopreservation Strategies for Sustainable Food Processing

About this Research Topic

Background

Ensuring the safety and quality of food, while minimizing the use of chemical additives is an issue that food manufacturers must address to meet the current consumers’ demand for healthier and clean label products. In parallel, other challenges such as the emergence of antibiotic-resistant foodborne pathogens and the occurrence of many foodborne pathogen outbreaks in the last decades have stimulated research on alternative food preservation methods. Traditionally, physical, and chemical methods comprising thermal processing and non-thermal technologies have been extensively applied to increase food safety. However, these methods may alter the overall quality of foods in terms of nutritional and organoleptic characteristics, and/or the costs of implementation at the industrial level making them inviable.

Food preservation using microorganisms such as lactic acid bacteria and/or their metabolites including nisin and phenylacetic acid has been investigated as a more sustainable and viable alternative for traditionally applied physical and chemical methods for food processing. The antimicrobial effects of these bioprotective cultures and antimicrobial compounds against spoilage and pathogenic microorganisms in foods have been intensively explored over the last few years. In addition, the effects of biopreservation strategies on food quality have been also addressed. The findings of research on biopreservation methods may help the development and optimization of more sustainable and viable strategies for food safety and shelf-life extension.

The aim of this Research Topic is to compile information on the recent advances in the application of biopreservation strategies to increase food safety and quality, especially in fermented food products. Therefore, this Research Topic seeks original research, review, and opinion articles related to the application of novel biopreservation methods for improving food processing and extending food shelf-life. Potential topics include, but are not limited, to the following:

1) Assessment of bioprotective cultures and/or their metabolites against pathogenic microorganisms in foods.
2) Evaluation of the bioprotective effects resulted from the application of biopreservation strategies combined with other emerging clean label technologies, such as high-pressure processing, ultraviolet radiation, and sustainable active packaging systems in foods.
3) Novel approaches encompassing predictive modeling of the interactions between bioprotective cultures with pathogenic microorganisms in foods
4) Risk assessment approaches towards the use of biopreservation strategies to increase food safety.

Keywords: lactic acid bacteria, bacteriophages, antimicrobial activity, microbial inactivation, shelf-life, food safety, predictive microbiology, microbial interaction, fermented foods

Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
