Research projects

Research programme

Campden BRI runs a research programme funded from multiple channels, including government grants and any other relevant source of funds. In addition, we dedicate time and resources to develop our own internal projects. The subjects chosen are inspired by our Industry Needs work, a result of member participation in our Member Interest Groups (MIGs) meetings.

Industrial relevance

The core of our research programme is focused on delivering practical solutions for food and drink challenges. Members are encouraged to participate fully in the generation of ideas and early discussion of results through participation in our Member Interest Groups. The emphasis of the programme is on practical outcomes and industrial relevance. The programme of research is organised into five strategic themes, which are drawn from our Industry Needs work.

MIGs

Member Interest Groups receive regular updates on project progress. This close engagement of members is vital in making the projects as relevant to industry needs as possible – so that they can deliver practical solutions to current and future problems.

About

Poultry feeds are very prone to contamination with salmonellae. Guidance (2020) from the Agricultural Industries Confederation (AIC) requires validation of kill steps used to reduce this, with revalidation at least 6 monthly. This project sought to design and validate challenge test methods to verify lethality of treatments. We learned some useful techniques for inoculation of very large volumes of low moisture products and have developed a protocol for microbiological challenge testing in poultry feed mills. We are seeking a joint publication on this. Unfortunately, avian flu and other restrictions prevented access to the planned AIC member sites for trials. However, we have generated inactivation data for Salmonella and its surrogate in poultry feed mash.

PhD

More information and outputs

About

The goal of this work is to establish an accurate model for the minimum pasteurisation requirements of beer. Current pasteurisation regimes for beer have been challenged by Rachon et al. (2018) and shown to excessively heat beer products, far above the level required to ensure destruction of all spoilage microorganisms. High levels of pasteurisation may result in deleterious effects to the organoleptic properties of the beer, and potentially waste time, energy and result in higher costs. Supplying our clients with a ready-to-use model for the accurate pasteurisation of beer will enable massive savings and have a positive impact on sustainability action.

Effective control of viruses

About

Why are we doing this project?

The control of foodborne viruses is becoming increasingly critical in the food industry, yet there is limited information directly applicable to foods. Norovirus, hepatitis A, and hepatitis E are currently the most concerning viruses. However, the technical challenges associated with culturing these viruses in the laboratory, coupled with the difficulty in distinguishing between infectious and non-infectious particles, complicate the assessment of virus stability and infectivity. To overcome these challenges, alternative methods, such as the use of surrogate bacteriophages like MS2 and Phi X174, are employed. These surrogate viruses enable the assessment of control measures on infectivity of the virus.

How are we addressing this issue?

This project is designed to evaluate the effect of heat on virus control, using bacteriophages MS2 and Phi X174 as surrogates for foodborne viruses. We will assess how heat treatments, combined with variations in water activity (aw) through the addition of solutes like sodium chloride, sucrose, and glycerol, impact virus stability and resistance. By comparing virus inactivation across different time/temperature combinations and water activity levels, we aim to generate reliable data on the effectiveness of heat treatments in reducing viral contamination in food products. The study involves applying heat treatments ranging from 60 to 85°C to bacteriophages MS2 and Phi X174 in solutions with aw levels of 0.88 and 0.99, analysing the results using regression models to determine the heat resistance characteristics of these viruses.

Tracking of microbial populations

More information and outputs

About

This project expects to develop a routine method that will allow us to track microbial population dynamics in food produce from its place of origin through to consumption. By understanding what time points and spatial surfaces are critical to the hygiene and longevity of the food product, this will allow us select key microbes to target during the cleaning and hygiene routines. Using non-culturable methods such as 16S Illumina Sequencing we hope to produce a better understanding of the microbiome by not selecting for any time, temperature, or chemical pressures. Upon collection and breakdown of this data we hope to establish a method of understanding the microflora and show a number of applications within food factory hygiene control.

Connecting consumers with their food via innovative virtual experiences

Martin Whitworth and Imogen Barker

PhD

More information and outputs

About

Traditional sensory testing booths, while efficient, cannot replicate the real-world experience that consumers have with food and drink products. This could potentially be compromising the validity of the data collected from traditional sensory testing booths. Immersive technologies offer a promising solution to allow effective data collection in more realistic consumption contexts.

This research project has developed a new approach, using ‘Mixed Reality’ (MR; and combination of virtual reality and real-life tools) and a range of bespoke design features, to facilitate product assessments in virtual environments. Consumers were invited to undergo the entire product evaluation process immersed in virtual kitchen and bar contexts.

The study showed participants adapted to the virtual contexts quickly, successfully using the technology to both evaluate products and record their responses via the embedded virtual questionnaire.

This new method offers several advantages:

  1. Cost-efficiency (by using entry-level, cable-free headsets (Meta Quest 2) rather than high-end tethered systems).
  2. Improves accessibility and usability (by using intuitive hand gestures for all virtual interactions).
  3. The experience’s programming guides participants through the study independently, minimising moderator intervention and facilitating a fully immersed experience.
  4. Efficient data collection from multiple consumers concurrently. Initial findings indicate that this innovative approach yields rich, insightful data not typically obtained in booth environments.
  5. Immersion in virtual bar and kitchen contexts boosts engagement and enhances consumers' ability to discern between products, highlighting the potential of using immersive technologies in sensory and consumer testing.

About

This project seeks to understand how we can use packaging as a communication tool for the environmental impact of food products to enable more sustainable consumption in the UK. It addresses the following questions:

  1. Consumption drivers: What environmental factors influence what consumers buy?
  2. Understanding: How many of the factors used to calculate environmental scores are understood by or cared about by consumers. What information would they like to have?
  3. Packaging: How is this environmental impact best communicated via packaging How do consumers respond to a physical-digital hybrid? Do they trust information on packaging?
  4. Impact of communicated environmental factors on sustainable consumption: Does this information influence choices of consumers towards more sustainable consumption?

Effectiveness and application of natural antimicrobials

More information and outputs

About

Why are we doing this project?

The demand for organic, vegan, and clean-label food products is on the rise, leading to an increased need for natural antimicrobial additives. These natural antimicrobials can help preserve taste and enhance flavour while controlling the growth of microorganisms, including pathogens and spoilage organisms. However, despite the wide range of natural antimicrobial products available on the market, there is a gap in understanding their application and effectiveness. Food producers and ingredient manufacturers require reliable data on the performance of these natural antimicrobials to ensure food safety and quality.

How are we addressing this issue?

This project aims to develop a comprehensive service that evaluates the application and effectiveness of natural antimicrobials. Initially, a range of natural antimicrobial products will be tested to assess their effectiveness against a variety of microorganisms. This will help determine the scope of their effectiveness by answering the question: "What types of microorganisms are these antimicrobials effective against?" (e.g., Gram-negative bacteria, Gram-positive bacteria, or moulds). The next stage involves determining the minimum inhibitory concentration (MIC) for some selected natural antimicrobials against a relevant species or group of microorganisms. Additionally, we will conduct microbiological challenge testing within actual food products produced with an antimicrobial product to verify their effectiveness within a food matrix against target microorganisms. This project will establish a range of tests and provide proof of concept for natural antimicrobial testing.

The use of tribology to understand and correlate oral processing and sensory perception

Amy Voong

More information and outputs

About

Project objective

Rheology has been extensively applied to associate in-mouth properties to sensory perception. However, rheology alone is not enough to explain mouthfeel perception. Lubrication between oral surfaces is a dominating mechanism that relates texture to mouthfeel. Tribology refers to the study of friction, wear and lubrication on deformable surfaces (tongue, palate and teeth). This project aims to evaluate the potential of instrumental tribology measurements for food.

Project progress

Dairy and non-dairy yoghurts were studied as a case study. Samples were characterised by rheology, particle size, microscopy and for tribology using an MTM instrument with a stainless steel ball and a silicone elastomer surface. Statistical comparisons were made with sensory assessments.

We concluded that, as currently applied, tribology cannot replace sensory assessments, but can be used as a supplementary physical characterisation method. The work has been completed and an R&D report is in preparation.

About

Why are we doing this project?

As with other sectors in the food industry, the poultry industry is increasingly facing the challenge of food fraud, where there is potential for lower-quality chicken meat to be sold as meat from premium breeds. This not only misleads consumers but also poses risks to public health and undermines the industry's integrity. In order to combat fraudulent activities, the food industry needs an accurate, reliable method of identifying one breed from another.

How are we addressing this issue?

Different chicken breeds will have a unique genetic profile and this project aims to address potential errors in the poultry supply chain, by developing a genomic analysis service to identify the breed of broiler chickens from meat samples. This initiative will establish methods for DNA extraction and sequencing, develop a bioinformatic pipeline for data analysis, and create a comprehensive breed database. By conducting blind validation trials, we will ensure the accuracy and reliability of the breed identification method. This service will enable precise breed verification, ensuring product authenticity and enhancing food safety and quality in the poultry sector.

Deciphering toxigenic profiles in bacterial pathogens

Research investment

More information and outputs

About

Why are we doing this project?

There are several food borne pathogens that produce toxins during their growth cycle, and it is these toxins rather than the organisms themselves that are responsible for food poisoning illnesses such as diarrhoea, gastroenteritis or worse. Controlling factors for growth of the organisms are well known but conversely, little is known about the conditions under which some key toxin-producing bacterial pathogens produce toxins in foods. Such information would aid effective food safety management strategies.

How are we addressing this issue?

This project aims to enhance our understanding of key toxin-producing foodborne pathogens— Staphylococcus aureus, Bacillus cereus group, and Clostridium botulinum— by identifying the environmental conditions that trigger toxin production. By focusing on critical factors such as temperature, pH, and water activity, we will explore the specific thresholds that promote toxin generation. The research will also refine methods for detecting these toxins in food, contributing to improved food safety protocols. The outcomes will bolster Campden BRI’s testing capabilities and knowledge regarding these pathogens, leading to more effective food safety strategies and intervention techniques to prevent food intoxication.

Research investment

More information and outputs

About

This project aims to enhance and expand Campden BRI's molecular capabilities, building on our next-generation sequencing services for members and clients. We are developing our whole genome sequencing (WGS) service with in-house trials to demonstrate its accuracy and effectiveness in identifying bacteria and yeasts (with moulds to follow later) to the highest level of identification currently possible. Furthermore, we are tailoring this service to meet the specific needs of our members by conducting additional research in two key areas: probiotics and spoilage within the brewing industry. By the conclusion of this project, whole genome sequencing will be an integral part of our molecular toolbox, designed to support your specific requirements.

Progress

Current work involves validating our methods against known sequenced genomes for probiotics and those associated with beverage spoilage. Our bioinformatics pipeline has been developed, and we plan to test it on unknown isolates in the new year. This approach will enable us to uncover new insights and expand our service offering beyond basic identification, allowing us to better meet the diverse needs of our members and clients, tailored to their specific situations.

Research investment

More information and outputs

About

In this project, the key beverage producers will be invited to cooperate. They will be asked to supply one or two products which will be used for validation. A minimum of ten different beverages (alcoholic and alcohol-free, beers, ciders, cocktails, soft drinks etc.) will be tested in this study. D and z-values of our yeast ascospores bioindicator and Enterococcus faecium NRRL B-2354 will be determined in each liquid, at 4 - 5 different pasteurisation temperatures (65 - 80°C), using the flask method and based on these values the optimised pasteurisation level will be calculated and verification trials will be performed in pilot plant flash pasteuriser (to be purchased). For each product, four trials (each at a different temperature/time condition) will be performed. One of these will be performed at standard pasteurisation conditions and the other three will be performed at optimised conditions. The energy consumption will be measured for each trial and usage compared. The outcome of the project will be presented at MIGs and several key conferences such as World Brewing Congress, Trends in Brewing, EBC/Brewers of Europe, IBD - Asia Pacific and on BruLab - Spotify/Apple podcast.

About

Rising costs of nitrogen fertiliser, the environmental impact of run-off and the carbon footprint of its production create pressure on the availability of high protein wheat. Although bread remains an important source of protein in the diet, members have challenged us to identify approaches to achieve good bread with lower protein wheat. This was one of the benefits of the Chorleywood bread process (CBP), but the challenge is to go further. Plant breeders seek to develop wheat varieties that deliver good gluten functionality from minimal nitrogen inputs. This project instead evaluates several potential baking process and recipe approaches.
