Key aims and expertise
The International Flavour Research Centre carries out world leading flavour research to address both the sustainability needs of our global food chain, whilst developing novel flavour insights and applicable solutions and technologies for the food industry.
Flavour is a combination of the aroma and taste of a food, and when you interchange food ingredients, reduce fat, sugar or salt, increase fibre or replace meat proteins with plant proteins, there are a series of highly complex flavour questions that need to be answered. For example, how do you develop foods that have reduced salt/fat/sugar and increased fibre without compromising the consumer experience? How do you ensure that nutritious plant based meat alternatives generate an equally appealing flavour during cooking and how do you ensure that when part of a complete meal they are a viable alternative for those who regularly consume meat?
These are some of the challenges we explore:
Aroma development and release: Aroma forms through complex reactions between different ingredients.
Optimising flavour generation pathways allows a previously unprecedented level of flavour control, offering commercial advantage and a mechanistic explanation of flavour release.
Through the use of model and semi-model foods, we explain the impact of food structure, food chemistry, and processing on aroma generation and release kinetics. This is achieved in real-time using bespoke high speed MS-NOSE2 technology to track volatile aroma compounds during processing and mastication.
Product reformulation and targeted design: We are researching ways to increase fibre and reduce salt/sugar/fat
by reformulating to enhance taste intensity, thereby enabling natural routes to increase the health credentials of foods.
This must be done whilst retaining the structure and eating experience, reducing fat and increasing fibre content. This requires a fundamental understanding at a molecular level of how these compounds bind to and are released from foods. By optimising the physics and chemistry of sodium-food bolus interaction we have shown that we can redesign food materials to achieve this goal.
Ultra-rapid digitisation of foods and flavour. We have
shown that cutting edge imaging and flavour profiling tools
can predict composition, processability, flavour generation potential, authenticity and adulteration.
When used in combination with advanced statistical tools such as machine learning, these techniques offer an unprecedented level of insight into food products.The unique range of techniques including E-Nose, E-tongue and hyperspectral imaging can classify samples at high speed and in a broad range of research and commercial environments.
Research with us
We are a dynamic research group with a range of post doctoral and PhD students. Our research vacancies are always listed on the University's recruitment pages. You may register an interest in a self-funded PhD/MRes by emailing your CV and evidence of funding to Jenny Drury.
Given the cross-disciplinary nature of food science, we also work closely with the University's Sensory Science Centre, Food Structure and Biomaterials Group and other research groups in the Biosciences field.

Professor Ian Fisk leads the International Flavour Research Centre and he is director of the consultancy and analysis service FACTS.
His research interests focus on designing effective and commercially viable flavour science solutions. This includes fundamental food chemistry to develop new ingredients or processes, flavour management during food production (plant biology, agricultural techniques, food processing, shelf life) and explaining the highly complex interaction of flavour with the oral-nasal environment during oral processing, whilst pioneering new approaches to increase sustainability across the food and flavour industries.
Dr Ni Yang is Assistant Professor in Flavour Science.
Dr Yang's research aims to shape a sustainable flavour system by embedding flavour science from soil and plant, processing and production, to consumption and health. Her current research includes flavour chemistry applied to the fields of tea and Traditional Chinese Medicine (TCM) and chilli/spicy sensations, whilst developing novel multimodal training approaches for parosmia post COVID-19 and anosmia in elderly.
Innovate with us
We work extensively with industry through FACTS - our analytical, consultancy and training service for food and bioscience industries.
FACTS offers high quality food chemistry and flavour science support for confidential and time sensitive enquiries - find out more on our dedicated website.
Learn with us
We run a highly popular one week Food Flavour training course - ideal for scientists in the food, drink or flavour industry and for students wishing to broaden their experience before entering the food industry.
The course can be attended face to face or entirely online and features a mix of live interactive classes and electures with leading academics, laboratory tours, equipment introductions and quizzes to check your understanding throughout the course.
