Through keyword compilation and bibliographic coupling analysis, the research topics identified are as follows: stability and functionality of food systems, ultrasound‐assisted processes, food oral processing and digestion, starch properties and modifications, and spray drying and microencapsulation. This comprehensive overview details the primary methods employed in particulate systems and highlights the influence of particles in the design of food systems.

Citizen way: Co-created citizen science meets convivial food design

This research approaches co-created citizen science from an interdisciplinary design perspective and is aligned with ideals of democratic and participatory co-creation of knowledge, its dissemination and implementation. We propose a new theoretical and practical design framework to be added to citizen science: convivial food system design. Convivial food system design is a new relational and tactical way to approach the development of a regenerative food system. Citizen science approaches can also benefit convivial food system design through activating communities of practice to share their insights and actively participate in co-food systems design processes. The integration of convivial food systems design and citizen science offers a deep, holistic and radical relation between amateur, civic and academic (scientific) knowledge in the production of alternatives to industrial food systems. This article shows the possibilities and potentials of this new conceptual integration through a theoretical framework and case study ‘experiment’ – the Huon Valley Food Hub project, Tasmania, Australia.

Reflection on the design of food systems and experiences for sustainable transformations

The importance of food and technology in modern society is undeniable. Technological advances have revolutionized how we produce, distribute and prepare food beyond local boundaries, and even how we eat. Eating is one of the most multisensory experiences in everyday life. All of our five senses (i.e. taste, smell, vision, hearing and touch) are involved. We first eat with our eyes, we can smell the food before we taste it, and then experience its textures and flavours in our mouth. However, the experience does not stop there. The sounds that come both from the environment in which we are immersed in while eating and our interactions with the food (e.g. chewing) and utensils we use to eat further influence our eating experiences. In all that, digital technology plays an increasingly important role, especially using emerging immersive technologies such as virtual and augmented reality (VR/AR). Designing at the intersection between technology and food requires multi-stakeholder commitments and a human experience-centred approach. Furthermore, it is essential to look beyond disciplinary boundaries and account for insights on various levels including the perceptual effects, experiential layers and technological advancements.

Servitization of Farming: A New Approach to Local Food Systems Building

Abstract The post-industrial service economy suggests new ways of thinking about food system design and building processes. This article discusses the need to explore best practices in the servitization of farming and theorize them as a new approach to food production, supply, and consumption. In contrast to prevailing theories that suggest reorganization of the global agri-food supply chain on the basis of the short supply chain concept or according to the community-supported agriculture model, servitization of farming puts forward a „made-to-order” food system. The purpose of this article is to develop theoretical and practical guidelines that suggest new ways of thinking about food system design and building processes. The article demonstrates the potential of a farming servitization to create new food system configurations through the combination of three approaches: holistic, design thinking, and evolutionary by providing a case study on a farm that uses a „service-driven” business model and makes-to-order organic vegetables, fruits, and greens. The case study approach allows in-depth, multi-faceted explorations and conceptualization of an innovative business model building process according to 5 phase design thinking model, which suggests gradual reorganization of the industrial food system as the result of farming servitization.

Studying the features of the use of neural networks and machine learning in the design of food systems

The features of the use of neural networks and machine learning methods for the design of food systems are studied using the example of processed cheese. A database has been developed that includes 869 cheese recipes, and a program for managing an electronic recipe directory. A neural network has been developed, for the training of which the method “Training with a teacher”, the activation function “ReLu” and the author’s program written in the Python programming language were used. The neural network consisted of 9 neurons in the input layer, two hidden layers of 65 neurons each, and an output layer consisting of 1 neuron. To determine the linear correlation between columns, a matrix was used showing the relationship between values using the Pearson coefficient. A training sample containing 80% of the total number of recipes, a test sample of 10% of the total number of recipes, and a test sample of 10% of the total number of recipes were selected from the primary data set. As a result of training the neural network, an information-advising system for a food technologist has been developed. The system is designed to predict the quality of food recipes. The information-advising system will speed up the correction of existing recipes and the development of recipes for new products, theoretically predict their quality before launching into production. The information-advising system was tested on a test recipe of a new processed cheese. It has been established that with a certainty of 63.6%, the integral indicator of the quality of the new cheese will be 7.7 conventional units. This predicted value was confirmed during the practical production of cheese according to the designed recipe in laboratory conditions and during approbation in production conditions. The new cheese is really distinguished by high quality, good organoleptic and physico-chemical parameters.

Assessing the Circularity of Nutrient Flows Across Nested Scales for Four Food System Scenarios in the Okanagan Bioregion, BC Canada

In light of continued nutrient pollution in water bodies and anticipated insecurities related to future nutrient supplies, there is an increasing awareness of the need to use nutrients in a more circular way. As part of a food system design study in the Okanagan bioregion, BC Canada we set out to evaluate different food system scenarios for the year 2050 in terms of nutrient circularity. In doing so, the objective was to evaluate the circularity of nutrient flows not only in the Okanagan, but also in relation to exogenous regions, insofar as nutrient flows relate to feed and food consumption and production in the Okanagan. This is important because feed and food trade means that nutrient inputs to crop production in the Okanagan may make their way into organic residuals outside the Okanagan, and vice versa. If not accounted for, this may lead to a distorted picture when analyzing nutrient circularity. To this effect, we applied an analytical framework and calculation model that explicitly tracks nutrients from crop production to organic residual generation. The results of the study suggest that assessing nutrient circularity across nested scales was critical for two reasons. First, changes in overall nutrient flows in response to population increase and dietary change were found to be more pronounced outside the Okanagan. Second, our analysis clearly revealed the extent to which feed and food trade boost nutrient self-reliance in the Okanagan at the expense of nutrient self-reliance outside the Okanagan. This kind of analysis should therefore be useful to explore, ideally together with food system and organic residual management actors, how different food system and organic residual management scenarios perform in terms of nutrient circularity, in the geographical area being considered, but also how it impacts nutrient flows and circularity in the places with which feed and food are traded.

A bibliometric analysis of food safety governance research from 1999 to 2019.

Although the number of food governance‐related studies increased rapidly in the recent decade, the current academic research still lacked systematic integration of food safety governance. To clarify the development trends of research therein, this study summarized research articles concerning food safety governance by the Web of Science Core Collection. An in‐depth bibliometric analysis was then conducted through CiteSpace to summarize the current characters and hot spots of food safety governance research, and predicted future research trends. Results showed that food safety governance was multidisciplinary, which included environmental science, food science, economics, and agriculture. The United States had the largest number of relevant articles, and Wageningen University was the most influential scientific research institution. Among all the journals in this field, Food Policy ranked the first in publication volume and co‐citation frequency. The development of food safety governance research was divided into three processes, namely the separate formulation of the standards for public and private sectors, the joint implementation of these standards, and co‐governance by multiple sectors. The most popular research hot spots in this field were food safety policy integration and public–private partnership of food safety governance. Lower‐ and middle‐income countries focused more on food supply and food system design, and regrettably not on food safety. Higher‐income countries cared more about food safety and food nutrition. Besides, researchers of higher‐income countries also concentrated on consumers' voices in participating in food safety governance. Food safety co‐governance, online food governance, the willingness to buy safe food, and food safety governance under pandemics were considered as future research directions.

International Trade and Investment and Food Systems: What We Know, What We Don't Know, and What We Don't Know We Don't Know.

Background: Globalised and industrialised food systems contribute to human and planetary health challenges, such as food insecurity, malnutrition, and climate change. International trade and investment can serve as a barrier or enabler to food system transformations that would improve health and environmental outcomes. Methods: This article used health impact assessment (HIA) to analyse what we know, what we don’t know, and what we don’t know we don’t know about the role that trade and investment might play in food system transformations to improve human and planetary health. Results: Evidence exists for the link between trade and investment and the spread of unhealthy food commodities, efforts to impede nutrition labelling, and increased concentration of ultra-processed food and beverage product companies. The role of trade and investment in the reduction of animal sources in human diets is emerging and may include challenging measures that restrict the use of terms like ‘milk’ and ‘burger’ in plant-based alternatives and the promotion of plant-based foods through non-tariff barriers and targeted efforts at regulatory harmonisation. Trade disputes may serve as the forum for battles around state discrepancies in the safety and acceptability of technological innovation in the food supply, as was the case with hormone treated beef between the European Union (EU) and the United States. Corporate social responsibility (CSR) obligations are unambitious but represent welcome progress in balancing public and private interests. Finally, introducing greater policy flexibility, transparency, and participation provides opportunities to shape a modern trade and investment system that can respond to future food system challenges in a timely fashion. Conclusion: Research at the intersection of trade and investment and food systems should address emergent food systems issues, particularly those that intersect health and climate, while policy efforts should be future-proofing the flexibility of the trade and investment system to enable food system design that supports improved human and planetary health outcomes.

Sustainable aquaculture through the One Health lens.

Aquaculture is predicted to supply the majority of aquatic dietary protein by 2050. For aquaculture to deliver significantly enhanced volumes of food in a sustainable manner, appropriate account needs to be taken of its impacts on environmental integrity, farmed organism health and welfare, and human health. Here, we explore increased aquaculture production through the One Health lens and define a set of success metrics - underpinned by evidence, policy and legislation - that must be embedded into aquaculture sustainability. We provide a framework for defining, monitoring and averting potential negative impacts of enhanced production - and consider interactions with land-based food systems. These metrics will inform national and international science and policy strategies to support improved aquatic food system design.

Innovation & entrepreneurship driving food system transformation

The current industrialized food system that is the predominant model of production in the United States and increasingly in other regions of the world has been recognized as a major contributor to greenhouse gas emissions, public health crises, environmental and soil health degradation, animal welfare abuses, labor crises and more. This article describes the evolution and design of food systems over time and the current assessment that a new system is required that focuses on planetary health and the health and well-being of humans and animals. The article describes the growth in entrepreneurship in the food system today and concludes that innovation is in need of increased support in order to advance a new operating system for how we grow, produce and distribute food.

Participatory Research towards Food System Redesign: Italian Case Study and Perspectives

Industrial agriculture and its requirement for standardized approaches is driving the world towards a global food system, shrinking the role of farmers and shifting decision-making power. On the contrary, a holistic perspective towards a new food-system design could meet the needs of a larger share of stakeholders. Long-term experiments are crucial in this transition, being the hub of knowledge and the workshop of ‘participation in’ and ‘appropriation of’ the research in agriculture over a long term. We present a methodology applied during the creation of a small network of organic farmers in Italy and detail the steps of the co-innovation process implemented. After a context analysis of the area to define the type of research and degree of participation, three steps were performed: (1) Identification of stakeholders; (2) dialogic identification of common activities; and (3) validation and feedback from participants. In the first participatory step, five organic farms were engaged for the second and third steps. We organized meetings to discuss future plans, facilitating the interaction process between farmers and researchers. These activities led to: (i) the definition of a research protocol based on farmers’ research needs for a new long-term experiment; (ii) committing farmers to take an active role in the research; and (iii) hosting experimental satellite trials in their own farms.

Temperate Agroforestry: How Forest Garden Systems Combined with People-Based Ethics Can Transform Culture

How can transforming monocultures to diverse polycultures address and solve the intersecting issues of our food system? This literature review offers community resources, practical examples, and academic research to support the shift away from monocultures, and the broader social contexts that encourage them, and towards food systems as part of cultures that prioritize people, water, and the land. Forest garden systems are presented as a temperate agroforestry-based food system design which make use of multiple perennial plants to meet human needs for food, medicine, fuel, and more while regenerating the environment in which they grow. There is a lack of peer-reviewed research in temperate forest garden systems, but it is gaining momentum alongside an increasing application in non-academic contexts. Combined with cultural principles that prioritize people, the land, and water over profits, forest garden systems are proposed as a pathway for meeting local community’s needs and environmental regeneration.

Local foods systems and community economic development

Local food system development is a popular strategy employed by many communities in the pursuit of sustainable and equitable economic growth and development. This often includes a range of economic projects including farmers markets, community supported agriculture enterprises, urban farming/agriculture projects, and food hubs. Sometimes it includes intermediated marketing channels like grocery stores and broad-line distributors interested in providing local foods. Despite growing prominence in the policy arena, many of the presumptions of the local food movement remain largely untested. This review provides critical analysis of current research on local and regional food networks and reveals that much of this research currently lacks strong theoretical grounding and quantitative rigor. As community development practitioners and planners play an important role in food system design, organization, policy, and implementation in an effort to produce community or regional wellbeing, it is important for them to distinguish between objective, research-based information and speculative, advocacy-oriented analysis.

Delineating the Southwest British Columbia Bioregion for Food System Design and Planning: A Practical Approach

In light of climate change, resource depletion and environmental degradation, food system vulnera­bility, and food insecurity, the potential to address issues of food system sustainability on local and regional scales is being increasingly recognized and pursued. Bioregions, generally defined as areas that share similar topography, plant and animal life, and human culture, represent an appropriate and consistently applicable scale and framework for sustainable food system analysis, design, and planning. As such, for a southwest British Columbia (SWBC) bioregion food system design and planning project, our first task was to delineate our bioregion. We report on the process, deliberations, and practical considerations that contributed to the determination of the SWBC bioregion for subsequent study. In addition to a complex biogeographic landscape that includes mountains, a major river system and delta, and a marine ecosystem, SWBC’s multicultural and urban/suburban/rural character is further compounded by its proximity to Vancouver Island, as well as by an international border with the Pacific Northwest United States; all represented important considerations in determining the dimensions of the bioregion. Bioregional-scale food system design and planning brings to the forefront the interdependency between human economy and community and the biophysical landscape with which they interact. In this reflective essay, we share our experience in the hope that it will inform the work of other communities in effectively delineating bioregions for food system design and planning that better align human communities and their economy with their environment. We believe the methodology presented has potential for widespread adaptation.

From Industrial to Artisanal: A New Regulatory Framework for a Changing Food Landscape

The Food Safety Modernization Act, passed in early 2011, is the most significant overhaul of the Food and Drug Administration’s food-safety authority since 1938. It reorients FDA to a preventive rather than responsive stance toward food contamination. The Act, however, will fall short of its goal of ensuring the safety of the food supply, for several reasons. It will be ineffective in significantly reducing foodborne illness because it is underfunded, and provides for too many exemptions. The use of preventive controls and science-based standards may also make it difficult for regulation to evolve as quickly as pathogens. In addition, the uncertainty caused by the Act’s attempt to incorporate flexible standards for smaller producers will inhibit market entry for small producers focused on marketing their products locally. Moreover, the Food Safety Modernization Act cements the disparate regulatory spheres of authority over food systems in the United States: on the one hand, rigid federal standards, and on the other a patchwork of state and local regulations, all of it haphazardly enforced. What is needed is a system of centralized decentralization, where states have broad flexibility to establish the structure of their food-system regulation, but are comprehensively overseen by the federal government. Such a system would improve information gathering and crisis-prevention capabilities, and would also serve a rationalizing function among the various spheres of regulatory authority over food. Furthermore, federal oversight of state food-system plans would allow for localities to incorporate other aspects of food safety beyond foodborne illness in food-system design.

Rebuilding northern foodsheds, sustainable food systems, community well-being, and food security

BackgroundMultiple climatic, environmental and socio-economic pressures have accumulated to the point where they interfere with the ability of remote rural Alaska Native communities to achieve food security with locally harvestable food resources. The harvest of wild foods has been the historical norm, but most Alaska Native villages are transitioning to a cash economy, with increasing reliance on industrially produced, store-bought foods, and with less reliable access to and reliance on wild, country foods. While commercially available market foods provide one measure of food security, the availability and quality of market foods are subject to the vagaries and vulnerabilities of the global food system; access is dependent on one's ability to pay, is limited to what is available on the shelves of small rural stores, and, store-bought foods do not fulfill the important roles that traditional country foods play in rural communities and cultures. Country food access is also constrained by rising prices of fuel and equipment, a federal and state regulatory framework that sometimes hinders rather than helps rural subsistence users who need to access traditional food resources, a regulatory framework that is often not responsive to changes in climate, weather and seasonality, and a shifting knowledge base in younger generations about how to effectively harvest, process and store wild foods.ObjectiveThe general objective is to provide a framework for understanding the social, cultural, ecological and political dimensions of rural Alaska Native food security, and to provide information on the current trends in rural Alaska Native food systems.DesignThis research is based on our long-term ethnographic, subsistence and food systems work in coastal and interior Alaska. This includes research about the land mammal harvest, the Yukon River and coastal fisheries, community and village gardens, small livestock production and red meat systems that are scaled appropriately to village size and capacity, and food-system intervention strategies designed to rebuild local and rural foodsheds and to restore individual and community health.ResultsThe contemporary cultural, economic and nutrition transition has severe consequences for the health of people and for the viability of rural communities, and in ways that are not well tracked by the conventional food security methodologies and frameworks. This article expands the discussion of food security and is premised on a holistic model that integrates the social, cultural, ecological, psychological and biomedical aspects of individual and community health.ConclusionWe propose a new direction for food-system design that prioritizes the management of place-based food portfolios above the more conventional management of individual resources, one with a commitment to as much local and regional food production and/or harvest for local and regional consumption as is possible, and to community self-reliance and health for rural Alaska Natives.

Uptake of Divalent Ions (Mn+2 and Ca+2) by Heat‐Set Whey Protein Gels

Divalent salts are used commonly for gelation of polymer molecules. Calcium, Ca(+2), is one of the most common divalent ions that is used in whey protein gels. Manganese, Mn(+2), is also divalent, but paramagnetic, enhancing relaxation decay rates in magnetic resonance imaging (MRI) and can be used as a probe to understand the behavior of Ca(+2) in whey protein gels. The objective of this study was to investigate the diffusion of Ca(+2) and Mn(+2) ions in heat-set whey protein gels by using MRI and nuclear magnetic resonance (NMR) relaxometry. Whey protein gels were immersed in solutions containing MnCl(2) and CaCl(2) at neutral pH. Images obtained with gels immersed in MnCl(2) solution revealed a relaxation sink region in the gel's surface and the thickness of the region increased with time. These "no signal" regions in the MR images were attributed to uptake of Mn(+2) by the gel. Results obtained with CaCl(2) solution indicated that since Ca(+2) did not have the paramagnetic effect, the regions where Ca(+2) diffused into the gel exhibited a slight decrease in signal intensity. The relaxation spectrums exhibited 3 populations of protons, for gels immersed in MnCl(2) solution, and 2 populations for gels in CaCl(2) solution. No significant change in T(2) distributions was observed for the gels immersed in CaCl(2) solution. The results demonstrated that MRI and NMR relaxometry can be used to understand the diffusion of ions into the whey protein gel, which is useful for designing gels of different physical properties for controlled release applications. Design of food systems for delivery of bioactive compounds requires knowledge of diffusion rates and structure. Utilizing magnetic resonance imaging the diffusion rates of ions can be measured. Relaxation spectra could yield information concerning molecular interactions.
