Scientists are attempting to recreate flavors using virtual data and a glass of regular water

Thanks to today’s technology, people can send messages or photos to each other with the blink of an eye, but what if you could send a friend a specific taste? Scientists at the National University of Singapore set out on this experiment to see people could actually taste an image that was sent to them. Thus, began their journey to digitally recreate the flavor and color of lemonade.

The scientists set up two team members in different rooms—one sending the digital information and the other receiving and drinking the beverage. The one who sent the information stuck a pH sensor into their glass of lemonade, transmitting the properties of the beverage to the receiver. The sent data went to a tumbler full of water where a series of RGB sensors would match the color properties of the drink.

The team perfected the color of the drink, however, to achieve the sourness of lemonade the tumbler had to implement a series of electrodes lining the rim of the tumbler to release an electrical pulse to the drinker’s taste buds. This pulse made the taste buds believe they were tasting a sour flavor. By combining these devices, the scientists had matched the properties for a tumbler full of water to closely resemble freshly squeezed lemonade.

 The team brought 13 subjects to come test their substituted drink, comparing it to real glasses of lemonade. They were not told which glasses were the real and which were the virtual recreations. In order to help hide the answers, the drinks came in three colors: yellow, green, and cloudy white.

The test subjects were asked to rate the drinks based on how sour their beverage looked and how it tasted. And the results? The subjects believed the virtual drinks had a sourer flavor than the real ones. However, when they drank their beverages, they described the real lemonade glass to have a more sour flavor than the virtual ones.

In the future, the team hopes to recreate any drink they desire and plans to include devices to mimic a beverage’s aroma.
