Researchers at the University of Warwick have pioneered the development of virtual flavors like marmite and vegemite, utilizing advanced technology capable of replicating nearly any food or drink flavor.

The development is not just a culinary marvel but has promising potential in the early diagnosis of Alzheimer’s disease through a novel taste test.

Development Process

Under the supervision of Professor Alan Chalmers, the flavors were constructed by analyzing samples of food and accurately simulating their taste, aroma, and mouthfeel.

New-Food Innovation, a cutting-edge food technology company, conducted the analysis, with the synthesized flavors conforming to UK Food Standards Agency guidelines, using approved food-safe chemicals.

Purpose and Application

The synthesized flavors are integral to Professor Chalmers’ research, conducted in conjunction with Superlunary Labs, focusing on the perception of taste and smell in humans.

The innovations aim at understanding the correlation between taste perception and neurological conditions like dementia.

A decline in taste perception could act as an early warning sign for diseases like Alzheimer’s, potentially allowing for diagnosis before the onset of more severe symptoms like memory loss.


The team successfully recreated the flavor of rooibos tea, which even the chief taster of a renowned rooibos manufacturer couldn’t differentiate from the real one.

The development of marmite and vegemite flavors began as an informal endeavor but eventually correlated with the main objective of exploring taste and smell as indicators of neurological conditions.

Comments from the Team

Professor Chalmers equated the flavor-making process to following a recipe, emphasizing the accuracy in simulating different flavor components, rendering the virtual taste indistinguishable from the real one.

He highlighted that these advancements could provide crucial insights into neurological conditions well before the manifestation of evident symptoms.

Malcolm Barnes from Superlunary Labs elaborated on their role in ensuring the delivery of virtual flavors through a calibrated, hygienic, and user-friendly device for analysis by Professor Chalmers’ team.


The development of virtual flavors by the University of Warwick not only stands as a testament to the advancements in food technology but also opens new avenues in the early diagnosis of Alzheimer’s and other neurological conditions.

The research, by bridging culinary science and medical diagnostics, has the potential to revolutionize the way neurological conditions are understood and diagnosed.
