Food scientists study how virtual reality can alter consumers’ tastebuds

Panelists rated the pungency of the blue cheese significantly higher in the cow barn setting than in the sensory booth or the virtual park bench.

Food scientists from Cornell University, Ithaca, N.Y., used virtual reality (VR) to show how people’s perception of real food can be altered by their surroundings, according to “Dynamic Context Sensory Testing–A Proof of Concept Study Bringing Virtual Reality to the Sensory Booth.”

“When we eat, we perceive not only just the taste and aroma of foods, [but we also] get sensory input from our surroundings – our eyes, ears, even our memories about surroundings,” says Robin Dando, associate professor of food science and senior author of the study.

About 50 panelists who used VR headsets as they ate were given three identical samples of blue cheese. The study participants were virtually placed in a standard sensory booth, a pleasant park bench and the Cornell cow barn to see custom-recorded 360-degree videos.

The panelists were unaware that the cheese samples were identical, and rated the pungency of the blue cheese significantly higher in the cow barn setting than in the sensory booth or the virtual park bench.

To control for the pungency results, panelists also rated the saltiness of the three samples, and researchers found there was no statistical difference among them.

The purpose of this project was to develop an easy-to-implement method for adapting VR technology for use in food sensory evaluation, says Dando.

“Our environs are a critical part of the eating experience. We consume foods in surroundings that can spill over into our perceptions of the food,” he adds. “This kind of testing offers advantages of convenience and flexibility, compared to building physical environments. This research validates that virtual reality can be used, as it provides an immersive environment for testing. Visually, virtual reality imparts qualities of the environment itself to the food being consumed – making this kind of testing cost-efficient.”

The was also authored by researcher Alina Stelick, sensory program manager at Cornell Institute for Food Systems; and summer undergraduate research scholars Alexandra Penano, University of California, Berkeley, Berkeley, Calif., and Alden Riak, Iowa State University, Ames, Iowa.
