Have a Swig of Virtual Lemonade

Depending on how it's eventually developed, this could be the gift that keeps on delivering the taste that refreshes -- and allows people to consume food and drink that they otherwise might not for health reasons.

Researchers from the National University of Singapore have come up with a way to reproduce certain flavors which can, having been delivered to your taste buds via electrodes, fool your taste buds into believing you're having a drink of lemonade instead of plain old water.

Think of it as teleported guilty pleasures.

New Atlas reports that the method of sending flavors works like this: By placing a pH sensor into a container of lemonade, researchers can take readings on the beverage's acidity, or sourness, while an RGB sensor scans the substance's color.

The collected data is subsequently transmitted to a simulator which uses an LED light to "color" water to look like lemonade. Electrodes then send specific impulses to the user's tongue, thereby simulating the sour taste of lemonade.

Researchers held blind taste tests so that subjects could tell them whether the artificially flavored lemonade water tasted like the genuine article. First, subjects were required to do a visual inspection as to which liquid looked more like the real thing. Then, consumption tests -- three of each substance, spanning two sessions -- took place.

The results indicated little difference in terms of visual appearance when the fake lemonade was illuminated with a yellow or green LED; they did suggest, though, that the fake lemonade looked more sour when it was lit up with a white LED.

When tasted, the real lemonades managed to rank higher on the sour scale than their doctored counterparts.
