According to reports, a number of passengers preferred to have tomato juice on planes. But, why people accept such food on planes? Researchers of a new study claimed that they have found why people are so inclined to the tomato juice even at 30,000 feet above the earth's surface.

The new study has been conducted at Cornell University. According to the study, it is all due to the noise levels on the flight. Food scientists at the university studied how the increased decibels on a plane could affect the palate. The scientists said they found that noise of the airplane enhances the umami, a strong and salty taste found in some foods, taste that is usually found in the tomato juice.

Robin Dando, assistant professor of food science at Cornell University in Ithaca, said, "Our study confirmed that in an environment of loud noise, our sense of taste is compromised. Interestingly, this was specific to sweet and umami tastes, with sweet taste inhibited and umami taste significantly enhanced".

The new study by Cornell University food scientists support a research that was commissioned by German airline Lufthansa in 2014. According to reports, the last year study was conducted after passengers were seen consuming as much tomato juice as they did beer on their flights.

Lufthansa commissioned The Fraunhofer Institute, which is Munich-based research organization, to investigate why passengers prefer drinking tomato juice on planes. During the study, the participants were asked to sit in an airbus A310 fuselage. In the plane, air pressure, flying conditions and noise were recreated.

According to the institute, at normal pressure, people do not like to have tomato juice, but during flight simulation the passengers said that they found the juice more pleasantly fruity.
