Background

Foams play a critical role in a wide range of food products, contributing to texture, mouthfeel, visual appeal, and overall consumer perception. From whipped creams and mousses to bread and ice cream, foamed structures are essential in both traditional and innovative culinary creations. The stability and formation of these foams depend heavily on the presence of surfactants and proteins that reduce surface tension and stabilize air bubbles within the food matrix. Over recent years, the demand for healthier, sustainable, and plant-based alternatives has driven significant research into new ingredients and processing techniques that can create and maintain desirable foam properties. This evolving landscape of food science calls for a deeper understanding of the physicochemical principles underlying food foams and the development of novel approaches to optimize their structure, stability, and functionality in diverse food systems.



The central challenge addressed in this Research Topic is the formation and stabilization of gas bubbles in food systems, particularly under conditions that align with consumer-driven demands for clean-label, sustainable, and health-promoting products. Although foams offer functional benefits such as improved texture, visual appeal, and reduced calorie density, their practical application is hindered by the inherent instability of gas-in-liquid systems. Conventional stabilizers—low molecular weight surfactants and proteins—often fall short in preventing bubble coalescence and disproportionation, especially in foams with small bubble sizes. Pickering stabilization, using solid particles to irreversibly adsorb at interfaces, represents a promising alternative, yet remains limited by the availability of food-grade particles with the necessary wetting and adsorption characteristics.This Research Topic aims to highlight recent advances in foam formulation, including novel stabilizing agents, physical modification techniques, and processing innovations. By bridging fundamental colloid science with applied food technology, the goal is to explore strategies that enhance foamability and long-term foam stability while maintaining consumer acceptability. A deeper understanding of these mechanisms could pave the way for the development of next-generation food foams that are both functionally effective and aligned with modern dietary and sustainability trends.



This Research Topic welcomes contributions presenting new insights, novel developments, current challenges, latest discoveries, recent advances and future perspectives in the field of foams and bubbles for food applications with a combination of experimental, analytical and/or computational approaches. A range of article types including original research papers, reviews, mini-review, opinions and perspectives will be considered for this Research Topic.

Topic editors

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
