Abstract

Food craving refers to an intense desire or urge to consume a specific food. In Western or Westernized societies, these craved foods usually have high palatability and are energy dense, that is, they have high sugar and/or fat content. Accordingly, the most often craved food is chocolate. Food craving is a multidimensional experience as it includes cognitive (e.g. thinking about food), emotional (e.g. desire to eat or changes in mood), behavioral (e.g. seeking and consuming food), and physiological (e.g. salivation) aspects. Experiences of food craving are common, that is, they do not reflect abnormal eating behavior per se. However, very intense and frequent food craving experiences are associated with obesity and eating disorders such as bulimia nervosa and binge eating disorder. The aim of this research topic was to gather new contributions to a variety of aspects of food craving, which include its assessment, cognitive and emotional triggers, moderators, and correlates of food craving, and the relevance of food cravings in clinical issues, among others.

Abstract

Materials and equipment in food processing industries are colonized by surface-associated microbial communities called biofilms. In these biostructures microorganisms are embedded in a complex organic matrix composed essentially of polysaccharides, nucleic acids and proteins. This organic shield contributes to the mechanical biofilm cohesion and triggers tolerance to environmental stresses such as dehydratation or nutrient deprivation. Notably, cells within a biofilm are more tolerant to sanitation processes and the action of antimicrobial agents than their free living (or planktonic) counterparts. Such properties make conventional cleaning and disinfection protocols normally not effective in eradicating these biocontaminants. Biofilms are thus a continuous source of persistent microorganisms, including spoilage and pathogenic microorganisms, leading to repeated contamination of processed food with important economic and safety impact. Alternatively, in some particular settings, biofilm formation by resident or technological microorganisms can be desirable, due to possible enhancement of food fermentations or as a means of bioprotection against the settlement of pathogenic microorganisms. In the last decades substantial research efforts have been devoted to unravelling mechanisms of biofilm formation, deciphering biofilm architecture and understanding microbial interactions within those ecosystems. However, biofilms present a high level of complexity and many aspects remain yet to be fully understood. A lot of attention has been also paid to the development of novel strategies for preventing or controlling biofilm formation in industrial settings. Further research needs to be focused on the identification of new biocides effective against biofilm-associated microorganisms, the development of control strategies based on the inhibition of cell-to-cell communication, and the potential use of bacteriocins, bacteriocin-producing bacteria, phage, and natural antimicrobials as anti-biofilm agents, among others. This Research Topic aims to provide an avenue for dissemination of recent advances within the “biofilms” field, from novel knowledge on mechanisms of biofilm formation and biofilm architecture to novel strategies for biofilm control in food industrial settings.

Abstract

The studies collected in this volume reflect, in general, upon food given its extraordinary cultural and identity value. With different approaches to food heritage, whether from a linguistic perspective, or from a more literary or cultural analysis, with a due historical, social and spatial framework, the set of papers highlight the importance of this topic, from classical antiquity up to the present day. In fact, food and everything that goes with it lead us on a journey revealing man’s way of life and his relationship with nature and other living beings. The thirty-four contributions of this volume are gathered in the following chapters: 1. Food: intangible heritage; 2. Food and literary heritage; 3. Food and linguistic heritage; 4. Food: health and wellbeing; 5. Food: society and culture; 6. Food and intercultural dialogue. With this volume it is also intended to open up perspectives on new research areas of food heritage as an essential source of knowledge for today.

Abstract

This book conveys many significant messages for the food engineering and allied professions: the importance of working in multidisciplinary teams, the relevance of developing food engineering based on well-established principles, the benefits of developing the field by bringing together experts from industry, academia and government, and the unparalleled advantage of working as globally as possible in the understanding, development, and applications of food engineering principles. I am delighted to welcome this book to the Series and I am convinced colleagues from all parts of the world will gain great value from it.

Abstract

From time immemorial fermented foods have undoubtedly contributed to the progress of modern societies. Historically, ferments have been present in virtually all human cultures worldwide, and nowadays natives from many ancient cultures still conduct a wide variety of food fermentations using deep-rooted recipes and processes. Within the last four centuries, scientific research has started to unravel many aspects of the biological process behind fermentations, which has contributed to the improvement of many industrial processes. During our journey in the research field, we have always been attracted to the development of scientific research around fermentations, especially autochthonous ferments: a natural repository of novel biomolecules and biological processes that will positively impact on many application fields from health, to food, to materials.

Abstract

Given the rapid growth of engineering fields, namely the food industry with novel food process technologies, novel ingredients, advanced enzyme production and applications, and other complementary technologies, this book will disclose the latest trends in food engineering. This text is a compilation of selected research articles and reviews covering current efforts in research in and application of emerging technologies in the food industry. The chapters in this book are divided into three broad sections. Section 1 deals with introductory information about enzyme application, preserving treatments (such as thermal treatment, active packaging concepts) in a sustainable, cost-effective manner, inclusion in food processing of wild edible plants as a part of cultural and generic heritage, and the upscaling of extraction techniques to increase the bioavailability of bioactive compounds. Section 2 provides data concerning the food industry's emerging technologies. Section 3 reveals the latest trends in food fortification. Overall, this book serves as an inspiring source for both scientific and industrial actors or anyone involved in any aspect related to the food industry.

Abstract

This book focuses on opportunities and challenges in implementing a bioeconomy strategy from a research and education perspective. It draws on contributions presented during the 30th EURAGRI annual conference held in Tartu (Estonia) in September 2016, as well as on other workshops organised as part of EURAGRI. EURAGRI is an informal gathering of EU research and higher education organisations and ministries interested in agri-food research. It works as a platform of exchange and discussion on topics of common interest pertaining to the organisation, orientation and outlook of agri-food research in Europe in connection with global changes.
