We’d all like to trust that the ingredients of our food products match their labels but unfortunately food adulteration – where certain ingredients are substituted for cheaper, indistinguishable alternatives – is rampant within the industry. Although such products can be identified using high-spec laboratory equipment, there is an urgent need for a portable and cheap detection system on the front line - a problem Paul Richardson has been addressing with the wider STFC Food Network+.
“The adulterated products that are caught are currently only the tip of the iceberg – we have no idea how much is circulating undetected” says Paul, whose interest in the issue began with his Master’s degree project which investigated whether spectroscopic methods could detect adulterated coconut water. Proclaimed as a natural ‘superfood’ with a wealth of health benefits, coconut water sales have rocketed over recent years. But severe allergic reactions and even deaths have resulted from counterfeit products containing undeclared cow’s milk, often used to improve the product’s appearance. For his Master’s project, Paul demonstrated that contaminated coconut water could be detected using Raman scattering, which irradiates samples with a laser beam and measures the pattern of scattered light. Depending on the types of atoms, some of the scattered light undergoes an energy change, causing the wavelength to shift. Examining the scattering spectrum produces a distinct ‘fingerprint’ that can be used to work out the molecular composition.
Whilst this works well in the lab on carefully-prepared samples, conventional Raman can’t be used on drinks still in the original packaging, which slows down the testing procedure. As Paul explains, “Conventional Raman only measures the scattering directly at the incident spot, meaning that surface scattering completely overpowers deeper signals. The only way to increase depth is to build a more powerful laser which would damage the sample”. At the STFC Food Network+ Sandpit event in February 2018, Paul’s supervisor Roy Goodacre (Formerly University of Manchester - now University of Liverpool) joined forces with Pavel Matousek (STFC Central Laser Facility) to pitch the idea for a project investigating a new technique for through-container detection: Spatially Offset Raman Spectroscopy (SORS). For Paul, it would perfectly combine his analytical skills, interest in food adulteration and thirst for research experience.
“I was delighted to be able to extend this work through the STFC Scoping Project award, particularly as SORS could be a very valuable detection technology within food systems” Paul says. SORS is based on the principle that deeper scattering is more likely to be detected at a spatial offset from the incident laser. Measurements are made at both the incident spot (to get the surface measurement) and at the offset (where more deeply penetrated signals are stronger than the surface), then statistical methods used to subtract the surface signal. Crucially, this allows greater penetration to be achieved without a stronger laser.
This time Paul turned his attention to adulterated fruit juices. Since pure products command a considerably higher ‘premium’ price tag, easy money can be made by substituting fruit sugars for high-fructose corn syrup. To see whether SORS can detect this, Paul prepared a range of fresh fruit juices adulterated with different amounts of syrup, but with the same total sugar concentration. Keeping things as realistic as possible, Paul tested the solutions in packaging from supermarket-bought products but immediately hit a problem. “We found that Tetra Pak and wax cartons completely stop the laser from getting through” he says. “It’s unfortunate since the vast majority of fruit juice products come in such packaging”. Undeterred, Paul persevered using transparent glass and plastic bottles, which admit laser light, and demonstrated that SORS does have potential for a portable system. “The proof of concept is absolutely there, all we need to do is tweak it” Paul says. “At the moment, there is still some noise from the outer packaging but our group are working on mathematical approaches to subtract this from the final signal”. Although fruit juices may be out at present, an alternative avenue for portable SORS could be the bottled oil market, since these frequently come in glass or clear plastic containers. “There is certainly a need since hazelnut oil is often used in place of more expensive oils, putting people with nut allergies at serious risk” he says.
“I’m very proud to be part of the SFN, particularly because as a group it is pushing forward to make the world a better place, working together with companies and industrial partners” says Paul. He particularly attributes it to helping him gain a thorough understanding of the academic world, including forming collaborations, sourcing funding and ‘learning about science I didn’t even imagine existed!” An enthusiastic cook, he has enjoyed learning how his technical skills can be applied to improve food systems for the future. “As an analytical chemist, it would be strange for me to not be interested in food: the kitchen is basically a tasting laboratory and one that deserves honest ingredients” he concludes.
A novel project combines drone technology, space science and reproductive biology to detect when cows are ready to be inseminated. Led by Niamh Forde, University of Leeds.
If you’re a dairy farmer, one of your biggest concerns is making sure your herd gets pregnant on time. Dairy cows only produce milk following successful calving, but there is a narrow window of time when a farmer needs an animal to become pregnant. Missing these opportunities can quickly generate losses of hundreds of pounds per cow, due to disrupted milk production and having to pay for multiple rounds of artificial insemination. Consequently, dairy farmers have to be on the lookout for when animals display ‘heat’: behavioural and physiological signs that cows show just before ovulation.
“Sometimes if you go out early in the morning, you can literally see the steam rising off the cows that are in heat, hence the name” says Niamh. “Unfortunately, most of the time the signs of heat are much more subtle and can be very difficult to see”. Current detection methods are far from perfect and can be very time consuming, for example observing mounting behaviour in a group of females. Given that a typical dairy herd can be over a hundred-strong, the need for a quick, accurate and affordable solution is clear.
It seems a problem made for Niamh, who has studied the molecular and physiological events of early pregnancy in a wide range of animals including pigs, cattle, mice, humans and even marsupials. But she arrived at her solution purely by chance. After a colleague couldn’t attend the STFC Food Network Sandpit event in February 2018, Niamh went in their place and “got chatting to the people on my table while charging up my laptop.” One of them was Stephen Serjeant, based at the Open University who designs algorithms to analyse temperature differences in distant galaxies. “I thought ‘If you can measure temperatures in galaxies so far away, then perhaps we could use it to detect heat in cows!’” she says. On finding that her other neighbour, Anthony Brown (Durham University) was an expert in drones, everything suddenly came together.
The basic idea is to scale down Stephen’s pattern-recognition algorithms to detect the distinct temperature changes in individual cows during heat. Once perfected, they hope to combine the program with drones fitted with infra-red imaging devices that can sweep across herds while they are out at pasture. A truly interdisciplinary project, it requires the expertise from all three researchers to be successful. Currently, they are demonstrating proof of concept using a static device mounted indoors. “We still need to work out how many data points we need for each individual cow so that we can accurately detect signs of heat” says Niamh. “This is where Stephen’s skills really come into their own”. Once optimised, they intend to move to using drones to conduct an outdoor experiment later this year with a herd of dairy cows synchronised to ovulate at a specific time. “This should give us a baseline set of data that we can use to refine the algorithm so that we get consistent outcomes” Niamh says.
A particular benefit about this technique is that it can be applied to farms with very different management systems, from small cooperatives in Sub-Saharan Africa to a high-end operation in the UK or USA. “Speaking to farmers has shown me that they are generally keen to use methods that are based on a physiological process, as it’s something they see occurring in their animals and understand”. If successful, Niamh envisages that this method could easily be applied to other areas, including reproductive management in conservation parks and zoos.
It’s been quite a journey for a self-confessed city girl: “My family think it’s hilarious that I now work with the farming industry as I grew up slap-bang in the middle of Galway city on the Irish west coast” Niamh says. Niamh moved to Leeds to start her own lab three years ago and since then has said that being part of the STFC Food Network+ proved invaluable in helping her to integrate into the food-science community. “The Food Network+ has allowed me to interact with people I wouldn’t necessarily have met otherwise, such as Stephen and Anthony, and made what I thought were ‘really difficult’ sciences such as astrophysics more accessible. It gives me the confidence to ask ‘stupid questions’ which often spark new ways of thinking about my own research”.
It is a fitting illustration of how the network creates opportunities for researchers from very different disciplines to design novel solutions towards more sustainable food systems. For Niamh, it’s been a very rewarding collaboration. “Reproductive biology is what I’m super-interested in and it’s been wonderful to use my fundamental knowledge towards helping farmers make a better living” she concludes. “The uterus is just the most awesome organ!”
“We’re working to address a critical knowledge gap challenge in the agricultural sector so that data-driven approaches can be used to enhance agricultural sustainability and productivity in China”.
As Professor of Supply Chain Management at the University of Roehampton, Wantao Yu has a vision to see a Big Data revolution transform the agri-food sector. Blockchain, Big Data and Internet of Things (IoT) technologies are being hailed as a game-changer for supply chains. Many of these systems are based on using online ledgers and databases to record transactions so that information can be accessed instantly (but not changed) by every member of the chain. The potential benefits for the food sector range from increasing transparency, guaranteeing province of origin, helping enforce environmental and food safety regulations and allowing farmers to access the best markets for their goods.
But many places face grand challenges in implementing digital technologies (e.g., IoT, blockchain and big data) in agricultural supply chains, particularly in rural regions of China, such as Henan Province. “In the news we hear that big progress has been made in China over the past 20 years but this has really been concentrated in major cities” Wantao says. “In the western and central regions like Henan Province, most farmers work only on a small scale and are currently experiencing multiple problems” including environmental pollution, mass-migration to urban cities and increasing concerns over food safety. Not surprisingly promoting digital technologies can be “a hard sell” as Wantao says: “Most farmers earn such a low income that their sole focus is on making more profit. Besides this, the average age of a rural farmer in Henan Province is between 50 and 60, so there is a huge knowledge gap when it comes to new technologies”.
Working with the STFC Food Network+, Wantao hopes to overcome this gap and deliver these technologies directly to those who could benefit. Working closely with Dr Tom Kirkham and Mr Tom Collingwood, IoT and Blockchain specialists at STFC Hartree Centre, Wantao has organised one workshop in Henan Province, China and another workshop in London, to discuss the potential applications of digital technologies in agricultural value chains. One of the reasons why he chose to focus first on Henan Province is that this is the official ‘breadbasket of China’, producing most of the country’s wheat and maize and containing over 50 million smallholder farmers. Crucially, Wantao has also already established a strong relationship with Henan University and Henan Agricultural University which deliver training programmes for farmers through its education centre (e.g. Science and Technology Backyard in Henan Province). In Wantao’s view, involving farmers from the start through workshops and focus groups will be key to delivering resources that they can understand and use. “We hope the farmers themselves will become the ambassadors” he says. In collaboration with Henan University and Science and Technology Backyard managed by Henan Agricultural University, he plans to use a whole range of media to facilitate this dissemination including leaflets, videos, brochures, posters, TV, newspapers and social media.
Wantao is also using his connections to encourage actors further up the food-supply chain to embrace digital technologies (e.g., IoT, big data and blockchain). It is currently a challenge for large-scale producers to coordinate supplies originating from widely distributed smallholder farms. Furthermore, this makes it difficult to work out the optimum growing regimes for high yields and ensuring good quality. Using IoT devices, including mobile apps, could make it easier for farmers to record and share information that could include fertiliser use, irrigation and pest control. Wantao has already secured the interest of Xinqi Garlic Agriculture Technology Co., Ltd., one of the key players in the local garlic sector, who hope to develop an online database and platform to link up all their suppliers and relevant value chain actors. This could provide a pivotal example of how IoT and Big Data can be used throughout the entire supply chain.
Policy makers also stand to benefit as these technologies could help ensure farmers are abiding by food safety and environmental regulations. “There is great urgency to reduce fertilizer usage, pesticide use, water consumption and pollution in the agricultural sector in China.” Wantao says. It’s thought that Blockchain could be particularly effective in managing food safety outbreaks, as all the relevant data will be instantly accessible without the need to retrieve information via third parties. This could allow sources of contamination to be traced in seconds, rather than weeks. Blockchain technology could also support farmers in making accurate decisions for sustainable production through providing data about soil conditions, water needs, fertilizer requirements, or weather forecasts. “Most rural Chinese farmers believe that more fertiliser is always better” says Wantao, “but having access to this data could help them to use just the right amount needed for maximum yields”.
Clearly with his vision, connections and passion for digital technologies, Wantao is in a unique position to move these technologies from theoretical possibilities to actual solutions. But he is realistic about the challenge that he faces, saying “We don’t have any successful examples at the moment of using Big Data and Blockchain in agricultural value chains in China. Hopefully this collaboration could establish a case-study and best practices for wider dissemination”. Whatever the result, it is clear that his work has already promoted a new wave of international collaboration between the UK and China and encouraged exciting innovations in the agri-food sector.
STFC HARWELL CAMPUS, 17-18TH JANUARY 2019
The 2019 STFC Food Network+ Showcase started with an insightful introduction to 21st Century Challenges from Professor Grahame Blair (STFC Executive Director, Programmes Directorate), setting the scene for the contribution that the SFN and STFC as a whole have made in this research area. This lead nicely into a rousing call to arms delivered by Professor of Population Dynamics Tim Benton (University of Leeds): “Our current food system is failing and inefficient, with the associated health and environmental costs being 5 to 10 times greater than the agricultural value of our food”. Describing the sheer complexity of the problem, and the daunting challenge of adapting to climate change, such an opening talk could have cast a pessimistic gloom across the meeting. But Tim wrapped up with an inspiring vision for how a positive future food system could look, including enthusiasm for the important role technology can play. Throughout the two days it was clear that the members of the STFC Food Network+ are using such challenges as inspiration for finding solutions through creative collaborations, new ways of using technology and rethinking entire supply chains.
We had come together to hear about the results achieved so far by the 20 projects funded in the 2018 STFC Food Network+ Collaborative Scoping Call. Although these covered everything from avocados to arsenic poisoning, there were noticeable themes uniting them together. One of these was the potential for Big Data and Internet of Things technologies to revolutionise the food system. We heard how the possibilities for these technologies are as varied as they are exciting, and applicable at both ends of food supply chains, for instance in determining the exact amount of fertiliser to apply or redistributing surplus food products. But as Guy Poppy (Chief Scientific Advisor to the Food Standards Agency, FSA) pointed out: “Data has no value unless it can be turned into wisdom”. Without identifying the metrics that are actually relevant to the user, one is simply left with a meaningless ocean of information. Many STFC Food Network+ projects are addressing this, ultimately helping Big Data technologies to make the leap from theoretical possibilities to effective solutions that, as one researcher put it, ‘bring benefits that result in cold, hard cash for farmers’ and other players in the food sector.
Working together with all the stakeholders in the agri-food sector was another common thread between these projects. Clearly, the most effective solutions can’t be developed in isolation from those who need them. Wantao Yu (University of Roehampton), for instance, is leading focus groups in Henan Province, China, to work out how Big Data technologies could best be applied to connect rural small holder farmers to agri-businesses. Similarly, Sonal Choudhary (University of Sheffield) convened multi-stakeholder workshops in India to identify the critical problems that cause up to 40% of fresh fruit and vegetables to be lost as food waste in this region. “We identified four key areas that could have immediate impact on farmer’s incomes if we targeted them” she said. “We found that connectivity, not productivity, is the main problem”. For those who worry about Big Data technologies usurping jobs and livelihoods, the ultimate aim for all these projects was rather to empower farmers and other actors in food supply chains to make better decisions. Examples included using weather-pattern data to decide which crops to plant (the FACYNation Project, Seb Oliver, University of Sussex); helping farmers to non-invasively detect pregnancy in cows (Niamh Forde, University of Leeds), and identifying potential avenues to redistribute surplus food (the APROV project, Luciano Batista, Aston Business School).
Besides digital technologies, we learnt how an impressive array of other sophisticated techniques are addressing specific industrial problems. Once again, these involved close collaboration with end users to deliver outcomes fit for purpose. After all, a technique may provide accurate, comprehensive information but it won’t be taken up within the industry if it needs hours to run, technical training and expensive equipment. We heard, for instance, how X-ray imaging can detect arsenic levels in rice grains (Manoj Menon, University of Sheffield); the potential of Raman scattering to single out adulterated fruit juices (Paul Richardson, The University of Manchester) and the use of volatile organic compounds to non-invasively ‘sniff out’ poor quality avocados and the freshness of bagged salads ( Marcin Glowacz, Natural Resources Institute, University of Greenwich and Hilary Rogers, Cardiff University). Excitingly, some projects are already at the stage of developing portable prototypes ready for use.
In between the presentations, there was a constant hum of discussion, catching up with friends, making new acquaintances and discussing new ideas and proposals to follow up. This, alongside the impressive portfolio of projects, underscores how valuable the STFC Food Network+ is as a forum for generating novel solutions and connecting up the expertise, funding and world-class facilities to make them happen. Representatives from various organisations, including DEFRA, FSA, BBSRC, NERC, STFC and InnovateUK , were on hand throughout to present their current opportunities for funding, making the search for ‘that perfect grant’ considerably easier.
We also had the chance to visit some of the impressive STFC facilities on the Harwell Campus, including the Diamond Synchrotron (capable of accelerating electrons to near-light speeds) and the RAL Space Centre. Watching a space satellite being tested in near-space conditions was a fitting reminder of just what science can achieve when we work together and reach for the stars. Rethinking the food system is perhaps just as great a challenge as launching into space… but the creativity and innovation found in the STFC Food Network+ is a real cause for optimism.

From rocket launchers to rocket salads, Geraint Morgan (based at The Open University) is always on the lookout for a challenge – and the SFN were happy to oblige!
Cancer detection, sports anti-doping, luxury fragrances, submarine air monitoring and space missions: Geraint’s work has embraced a staggering array of fields. The common thread linking them all is his expertise in Gas Chromatography-Mass Spectrometry (GC-MS): a sophisticated technique for separating and identifying the different chemical compounds in samples. As Geraint explains; “Everything produces a unique smell- a distinct profile of volatile organic compounds”. Having trained as an analytical chemist, Geraint’s research career started by investigating how GC-MS ‘fingerprints’ of stable isotopes could model global sources of methane and their respective roles in climate change. He then turned his attention from Earth’s systems to more distant realms, joining the teams behind two space missions.
The first of these concerned the Rosetta Lander, Philae, and resulted in a miniature GC-MS system called Ptolemy which successfully analysed the chemical composition of the comet Philae landed on. Later, Geraint developed a similar system for the Mars Lander Beagle 2 to analyse rock samples for organic samples indicative of past life. Sadly, communication was lost with Beagle 2 after it landed, however the missions gave Geraint a suite of capabilities and a network of contacts ideal for problem solving back on Earth. “Having a planetary science background gives you a diverse skill set, besides the experience of working as part of a multidisciplinary team including chemists, physicists, mechanical and software engineers, geologists and microbiologists” he says. Looking for a new challenge, he attended an SFN workshop at Rothamsted Research recommended to him by Stephen Serjeant, the SFN Champion for STFC Technology. Here he found no end of potential avenues for his specialist expertise. “My first SFN workshop alone resulted in two successful projects, besides half a dozen potential new partnerships in a range of areas from chickens to blackfly larvae to Scotch whisky” he says.
Both these projects address one of the biggest challenges in the food retail sector: food waste. According to the UK waste advisory body WRAP, 1,200,000 tonnes of fresh fruit and vegetables are needlessly wasted each year. At the workshop Geraint and his colleague Simon Sheridan met Hilary Rogers (Cardiff University) and in turn her colleague, Carsten Müller, who were working on reducing waste from bagged rocket salads. Using GC-MS technology, they had already demonstrated that cut leaves have a distinct molecular fingerprint that can be used to predict shelf life. However, this required expensive, bulky laboratory equipment: the challenge now was to develop a portable device that could be easily used throughout the value chain. Geraint and’s Simon work on the space missions proved ideal training: “The space community is very good at thinking outside the box and making things that are small, robust, built to survive and that don’t require a mains plug!” he says. Having demonstrated proof of principle for the device, they are now at the stage of considering applying for follow-on investment funding.
The second project concerns the avocado industry, growing at a phenomenal rate but with a high level of associated waste. “Although they may look fine on the surface, one in five avocados develops disorders in the flesh, for instance browning and/or fungal decay, causing most people to throw them straight into the bin” says Geraint. Working with Marcin Glowacz, (Natural Resources Institute/University of Greenwich) Geraint and his colleague Simona Nicoara are developing a system to non-invasively ‘sniff out’ these blemished beauties at importers and ripeners, i.e. before they are sent to the retailers. Currently they are trapping organic compounds released by avocados then analysing them with GC-MS to see if there is a distinct fingerprint that can differentiate browned specimens. As with the rocket salad, the challenge will then be to develop this into a tool that can be easily used by the supply chain. “Ultimately, we aim to enable importers in the UK to ensure that only good quality avocados enter the UK fresh produce market, while transferring the poor-quality fruit into other industries, so that they can be converted to other products, such as oil.”
Rather than slowing down, Geraint’s workload only seems to accelerate and expand into new fields. One of his latest projects is a medical diagnostic device to detect the bacteria that cause stomach cancer, one of the biggest killers in India. “It’s amazing to think that the same analysis methods we performed to look for signs of life on Mars are now being used to potentially save millions of lives here on Earth– a nice legacy from the mission”. Having made quite a leap from space missions, Geraint recognises the role that networks played in making this lateral move: “These networks such as the SFN function very well in bringing different people together so we can see how our technologies could potentially offer a new solution for the community. I get such a thrill from tailoring a new product to be exactly the right thing for the end user”. No doubt it won’t be long before he is ‘sniffing out’ the next challenge!

In February we held two sandpit events focusing on 'Transforming Food Supply Chains for a Sustainable Future' and 'Measuring the Ground Truth'. These were attended by ~70 people from across the fields of Physics and AgriFood including attendees and speakers from DEFRA, STFC, BBSRC, GFS, InnovateUK, industry and academia. After pitches on proposed projects, and a democratic voting process by sandpit participants, two winning projects were selected for funding - 'Project APROV - Augmented Procurement Visibility - Developing the self organising capability of agricultural procurement systems' and 'Continuous Ammonia Monitoring for AGriculture - CAMAG'.
At around the same time we also launched our first call for collaborative scoping projects and have been delighted to be able to fund more than 20 projects, all of which are cross-council or between STFC and industry. You can find out more about all of these projects here. Examples include:
We'll have talks on all of our funded projects at our Annual Meeting on the 28th and 29th June so don't miss this chance to find out more and make the connections that could help you to be one of our next successful award winners. Registration is open now.
You can see how our projects fit across our themes in this updated version of our intersections diagram:
Following the buzzing SFN Launch meeting in June, we were delighted to announce the appointment of 6 SFN Champions who are now poised to engage with their respective communities and with each other to catalyse new interdisciplinary ideas.
The SFN is based around interactions between food challenges and STFC capabilities as follows:
The overall goal of the network is to fill the above intersections with active projects and help them to get going enough to continue beyond the network through other funding and/or industry. We are delighted to have found broad, well-connected, collegiate and dynamic experts on each of the 3 food and 3 STFC areas. They will reach out and enthuse to the communities in their areas about the potential of the network, brainstorm with each other about possible connections, and encourage new interactions.
Theme 1: Sustainable Food Production
This theme is focussed on developing food production systems that maintain healthy soils, reduce impact on the natural environment and provide reliable yield in the face of changing climate. SFN Champion for Sustainable Food Production, Simon Pearson, has a wealth of experience within the agri-food sector both in academia (Reading and Lincoln) and industry. His industry domain experience includes 8 years within the Marks and Spencer food group and a further 8 years running farming companies in the UK and Portugal. Simon now leads the Lincoln Institute of Agri Food Technology that conducts interdisciplinary and collaborative research with industry, key focus themes are the use of robotics in agri-food (soil sensing, crop picking and the use of autonomous vehicles), the impact of water on agricultural systems (diffuse pollution, salinisation) and the application of digital technology in agri food (IoT, system modelling and control). He is PI of an STFC Ag Tech China grant that is deploying novel sensor technology on robotic platforms to measure soil moisture. The data gathered will be used to support the development of radar based EO techniques to estimate soil moisture.
Simon is a passionate advocate for interdisciplinary research. The vast and complex food system is ultimately interdisciplinary and consumes biological, engineering, physical, social, digital, environmental and economic sciences. The challenges facing the food system are highly complex and in Simon’s view large scale and interdisciplinary approaches are needed to find solutions. The SFN now provides an ecosystem that encourages interdisciplinary research by matching industry, academia and funding mechanisms to drive sustainability in the food system.
Following discussions at the launch meeting he is currently particularly excited about STFC facilities can be deployed within the agri food domain, in particular the STFC capability in data science. There is no doubt that digital technologies (IoT, blockchain, digital connectivity and architectures) will drive productivity and system sustainability in the future, however, the data requirements and opportunity in the food system are so vast that new digital approaches will be required. Simon would like to hear from you about your ideas for possible projects.
Theme 2: Resilient Food Supply Chains
This theme goes from farm to fork, covering the monitoring, modelling and design of food supply chains to enhance resilience, environmental and social benefits, and public health. “Owing to global challenges such as climate change, growing population, dietary transitions and changing supply chain dynamics, it’s imperative to understand the potential risks within the food supply chains, and enhance the capabilities to analyse and mitigate them”, says Sonal Choudhary, SFN Champion for Resilient Food Supply Chains. In addition to building resilience, it is equally important to maximise value in supply chains through the use of disruptive technologies and advanced data sciences.
Fortified with strong educational and research backgrounds in plant sciences, environmental sciences and agri-food supply chains, Sonal is an ardent believer of multidisciplinary research and in it’s potential to combat the complex challenges thrown by the global food systems. She is focussed on building resilience through the development of unique taxonomies of vulnerabilities and mitigating capabilities within the food supply chains, which can be categorized to represent key actors from different tiers across the food supply network.
“I’m particularly enthusiastic about the potential of the STFC data science, computational facilities including e-infrastructure for supporting large-scale data analysis and technology for building resilient agri-food supply chain that could provide opportunities for value maximization for all the stakeholders”, says Sonal.
Sonal is currently working at Sheffield University Management School, where her research focuses on UK agri-food value chain risk analyses, sustainability performance of global food supply chains, and identifying inefficiencies within the supply chain and exploring value maximisation opportunities using continuous improvement cycle. Most recently, Sonal initiated a few projects co-designed with industrial partners that involves identifying and evaluating risks based resilience at production, processing and retail level.
She is particularly interested in researching how big data and disruptive technologies such as IoT and Blockchain can be used for value maximisation and building sustainable food systems. Sonal strongly believes in collaborative research and would like to invite interests for new research ideas and potential projects.
Theme 3: Improved Nutrition and Consumer Behaviours
This network extends all the way to investigating consumers’ dietary needs, food preferences and practices as well as focusing on questions of food supply, affordability and distribution (addressed in Themes 1 and 2), all critical to developing sustainable nutrition. The SFN Champion for Improved Nutrition and Consumer Behaviours, Christian Reynolds is enthusiastic about the using STFC facilities, data science, technology, modelling and computational approaches on the challenge changing consumer behavior to enhance nutrition and health whilst reducing waste and demands on land, energy and water.
Christian is currently working at the University of Sheffield, where his research is examining the economic and environmental impacts of food consumption; with focus upon the energy impacts of cooking, consumer food waste, and sustainable dietary shifts. He would love you to get in contact if you are interested in the scope of Theme 3.
Running across each of these food themes is existing STFC expertise that can address important research questions within and between the food themes, and catalyse new research activity:
Expertise A: STFC Data Science
Astronomers and particle physicists routinely analyse terabytes of data in large international collaborations which share code and frameworks. This necessitates the use of novel algorithms to sift and/or extract the key information about the Universe.
SFN Data Science Champion Seb Oliver is a Professor of astrophysics specialising in surveys of the sky with telescopes operating at a variety of wavelengths to understand galaxy evolution. He has a particularly interest in applying novel statistical techniques to these big data challenges. He has developed a strong track record in interdisciplinary research applying astronomical data analysis methods to other fields with grants and publications in biochemistry and medical areas, including MRC Discipline Hopping, STFC Challenge funding and a Wellcome Trust Seed award. He has been a member of the MRC Discipline Hopping panel. He currently leads a multi-institute centre for doctoral training in data science in the South East which will train around 60 PhD students.
Astronomers like Seb routinely analyse images of large fractions of the sky, taken in multiple wavebands and at a range of resolutions, e.g. to measure the age and chemical composition of stars and galaxies in the presence of confounding emission from the atmosphere. These techniques could be applied to remote sensing observations looking down on the earth, to identify crop species and stressors e.g. to better inform interventions such as pesticide application.

STFC also funds the UK particle physicists, who play important roles in analysis of particle collisions that happen 600 million times per second within the Large Hadron Collider (LHC) at CERN, each often decaying to create new particles. The ~30Pb of data collected every year by these measurements must be combed through to find new physics, such as the Higgs boson. Building on the technology of the world wide web, invented at CERN in 1989, the CERN computing structure allows 8000 physicists near real-time access to LHC data.
Expertise B: STFC Technology
STFC researchers routinely push the boundaries of cutting edge technology for building space, CERN and STFC instrumentation e.g. precision engineering of lens systems to a fraction of the thickness of a human hair and hyperfast and/or sensitive detectors.
Stephen Serjeant is the STFC Food Network+ Technology Champion. He is the Open University’s Professor of Astronomy and specialises in extragalactic galaxy surveys, infrared astronomy and strong gravitational lensing. The Open University has a long history in space instrumentation, including CCDs, CMOS detectors, gas chromatography–mass spectrometry, and much else. Major mission instrument involvement and leadership includes Philae that landed on comet 67P/Churyumov–Gerasimenko, the Mars Curiosity rover, the first phase of the ExoMars mission, the Huygens lander on Titan, XMM-Newton, Chandra, Swift, GAIA, Chandrayaan-1 and 2, UKube-1, Euclid, AlSat-Nano, JUICE, Athena, SMILE and WFIRST. Stephen is the deputy UK Project Scientist for the proposed SPICA space telescope and works closely with instrumental colleagues in Euclid and other missions. Stephen is very keen to find ways to find ways to deploy STFC space technology expertise to new domains in food, particularly in addressing the UN Sustainable Development Goals.
STFC has designed over 200 instruments for space missions. As explained by Stephen “These instruments have to be extremely robust to survive accelerations of several g during launch, and to survive the ultra-hard vacuum and harsh radiation environment of space. They also have to be extremely compact, light and low-power, as physical space, mass and electrical power are almost always at a premium in a spacecraft.”
Beagle-2 and Rosetta spacecraft’s lander Philae contained GC-MS instruments to measure the composition of the comet. Based on this technology the team developed a low mass, low power tuberculosis detection GC-MS for use in the developing world. There are many ways this technology could be applied to food research, for example by detecting moisture damage to cocoa beans, or levels of volatile molecules like pesticides.
Expertise C: STFC Facilities
The Science and Technology Facilities Council operates and provides access to world-class large-scale research facilities and manages the UK access to large-scale facilities in other countries. These facilities underpin UK scientific research across all areas and include ISIS (the UK’s neutron and muon source), Diamond Light Source Ltd. (the UK’s synchrotron facility), and the Central Laser Facility (CLF) as well as high-performance computing and modelling (http://www.stfc.ac.uk/funding/access-to-facilities/)
Sarah Rogers is the STFC Food Network+ Facilities Champion. She is also the small-angle neutron scattering (SANS) team leader at ISIS and the instrument responsible for the world-class SANS beamline Sans2d. She has been a SAS facilities scientist since 2006: firstly, as a junior beamline scientist at Diamond Light Source Ltd. and then joining the ISIS SANS team in 2008. Sarah’s expertise include using SAS to study multicomponent colloidal systems and performing in-situ measurements (including mixing and flow, heating/cooling and pressurizing) both of which are very relevant to food science. Sarah works closely with the Industrial Liaison Team at ISIS and Industrial Users are regular visitors to the SANS beamlines at ISIS. Sarah is always keen to grow the user base of all the STFC facilities and believes that certain areas of food science could really benefit from becoming part of that.
As explained by Sarah: “The CLF provides high power lasers which can be used to study the movement of individual molecules in living plant cells to be observed in real time - this information could hold the key to making crops more disease-resistant.”
X-rays (left) and neutrons (right) can provide very different views to the inside of living organisms. Here a classical X-ray image of a hand shows how the X-rays highlight the metallic elements in a sample whereas the neutron image shows how the neutrons pass through the lead casket containing a rose but highlight the lighter elements (carbon and hydrogen) within the flower.
“Both ISIS and Diamond can be used to study particle sizes and aggregation in food samples without the need for any special sample preparation (such as drying). The samples can also be modified (heated, mixed, pressurised etc) in-situ which allows users to see how the structures within their samples change in real time. The complementarity of neutrons and X-rays allows scientists to gain a very detailed picture of the materials being studied.” said Sarah.
Astro, particle and nuclear physicists set to tackle global food challenges
The STFC Food Network+ (SFN) launches today, bringing together hundreds of people to bring new capabilities to bear on the challenges of providing a safe, sustainable, nutritious and affordable supply of food for all. The launch is marked by a meeting today and tomorrow in Manchester. The SFN will catalyse and fund collaborations between food researchers and research and facilities funded by the UK’s Science and Technology Facilities Council (STFC).
“Food contributes over 20% of greenhouse gas emissions and will likely be the main way most people experience climate change” says Prof. Katherine Denby, of the University of York and SFN co-lead, “We need to produce safe and nutritious food in a sustainable way without depleting natural resources, and ensure the accessibility and resilience of food supply. The UK’s STFC can play a major role in helping to address these challenges, by bringing access and expertise in the UK’s biggest facilities as well as big data and precision instrumentation expertise from fundamental research in astro, particle and nuclear physics.”
Prof. Sarah Bridle, of the University of Manchester and lead of the SFN, is optimistic about the potential for STFC researchers to contribute to solving food challenges “For example, in my astronomy research I analyse images of galaxies from multiple observations of large areas of sky taken at different light wavelengths from optical through to infra-red. I’m now using the same tools to cut out observations of fields of wheat and look for signs of weed infestation.”
STFC is always looking to explore the existing and potential capability of the whole STFC research community in food research, with the aim of broadening the impact of STFC’s science and technology into areas that are strategically important to the UK. STFC is able to contribute key capabilities in a number of important areas including in high performance computing, in particular in modelling and optimising large data sets; utilising our major facilities that include the UK’s key ISIS Neutron and Muon Facility, the Central Laser Facility and access to Diamond Light Source Ltd. These facilities offer researchers the ability to research processes and materials in detail. STFC also has access to robotics and autonomous systems.
An editorial piece in Physics World last year ended with “Particle theorists achieve many things, but tackling the world’s obesity crisis is not something they can ever hope to address’', but Bridle disagrees “I think we’re going to be surprised at the new connections that get made. One project to count pollinators in a field produces images of white dots moving across a dark background - show this to a particle physicist and they get excited about the potential to use tools they already developed to analyse particle tracks at CERN!”
Prof. Mark Reed of the University of Newcastle is an expert in trans-disciplinary research and research impact in food systems, and co-lead of the SFN “There definitely seems to be an appetite for these two communities to engage with each other, with over 600 responses to the pre-launch survey that ran last month. We set ourselves the target of getting 300 people on our mailing list by the end of the 3 year project, but there are already over 400 people signed up” says Reed.
The SFN Launch meeting today will present food challenges from agriculture, food supply and safety, through to consumer food waste. The STFC participants will showcase their capabilities today, culminating in a presentation of STFC-funded project Zooniverse which brings hundreds of thousands of people from around the world to assist professional researchers. Says Prof. Chris Lintott, Zooniverse PI and Co-founder. “I’m looking forward to understanding what bottlenecks occur in supplying the world with safe food, and how our community can help”.
The STFC Food Network+ runs for 3 years and will fund proof of concept studies, visits between researchers, small focussed meetings, and annual network meetings like the one today.

About The STFC Food Network+
The Science and Technology Facilities Council (STFC) Food Network+ (SFN) aims to bring together STFC researchers and facilities with research and industry in the agri-food sector. The SFN will build an interdisciplinary community working to provide a sustainable, secure supply of safe, nutritious, and affordable high-quality food using less land, with reduced inputs, and in the context of global climate change and declining natural resources. The SFN will highlight and develop key opportunities for the STFC community to make a meaningful contribution to the food system - from sustainable intensification, through building resilience in supply chains to novel technologies to engage consumers and help change behaviour and improve nutrition.
