Why plane food tastes different and which flavours work best at 30,000 feet

Scientists have come up with an answer for why the food tastes different when you're on a plane.

If you've ever taken a sip of your drink on a flight and been left wondering why it tastes funny, you are far from alone.

Experimental psychologist Charles Spence is a professor at the University of Oxford, and back in 2014 he conducted a study into how one particular factor on a flight might affect the way you taste things - the noise.

While planes have come a long way since the Wright Brothers, the sound of a roaring jet engine still penetrates into the most insulated of cabins, though the noise may also be some comfort to passengers in need of reassurance that yes, the engines are still working.

Spence's work found that the noise of the engines can dull some of our tastes, including sweetness, which explains why the super sweet soda might taste noticeably different, Atlas Obscura reported.

Strangely other flavours even seemed to be enhanced by the noise, for example umami which is a savoury taste.

This discovery has even led to suggestions that the menus on flights be curated to favour umami-heavy foods such as tomatoes, mushrooms, or parmesan cheese.

Some airlines in Scandinavia and Hong Kong have even started serving special beers which have been brewed specifically to emphasise the flavours which are enhanced at high altitude.

In the case of British Airways, there was even a 'Sound Bites' feature where passengers could listen to a special playlist while tucking into their food, which they introduced in 2014.

That's certainly a long way from a lukewarm sandwich on a budget airline.

Spence also carried out a scientific experiment where he and other academics found that sweeter flavours tend to be enhanced by higher pitched noises.

Meanwhile, bitterness was brought out by sounds with a lower pitch, while whether a food was crunchy or making another noise also contributed to how people eat it.

You've heard of 'the first bite is with the eyes', but it turns out our ears also get in on the action.

Plane food is not exactly known for being the finest of fine dining experiences, but it turns out that sound is not the only thing which could be affecting your taste buds in mid air.

Ex flight attendant Mandy Smith opened up to LADBible previously about all the different things which might alter the way that you taste your food on a plane.

"It’s not the food that’s bad, it’s your taste buds that are different in mid air," she said."The pressure of the cabin affects your whole body, even your taste buds."

She added: "It affects all of your gastric anomalies, your brain and everything. It does affect your taste buds as well."

This theory around cabin pressure was corroborated by Russ Brown, the director of In-flight Dining & Retail at American Airlines, who told the BBC: "Flavour is a combination of both, and our perception of saltiness and sweetness drop when inside a pressurised cabin."
