Science Reveals Why Airplane Food Tastes So Bad

Hugh Pickens writes "At low elevations, the 10,000 or so taste buds in the human mouth work pretty much as nature intended. But step aboard a modern airliner, and the sense of taste loses its bearings. Even before a plane takes off, the atmosphere inside the cabin dries out the nose. As the plane ascends, the change in air pressure numbs about a third of the taste buds, and at 35,000 feet with cabin humidity levels kept low by design to reduce the risk of fuselage corrosion, xerostomia or cotton mouth sets in. This explain why airlines tend to salt and spice food heavily. Without all that extra kick, food tastes bland. 'Ice cream is about the only thing I can think of that tastes good on a plane,' says Marion Nestle, a professor of nutrition, food studies and public health at New York University. 'Airlines have a problem with food on board. The packaging, freezing, drying and storage are hard on flavor at any altitude, let alone 30,000 feet.' Challenges abound. Food safety standards require all meals to be cooked first on the ground. After that, they are blast-chilled and refrigerated until they can be stacked on carts and loaded on planes. For safety, open-flame grills and ovens aren't allowed on commercial aircraft, so attendants must contend with convection ovens that blow hot, dry air over the food. 'Getting any food to taste good on a plane is an elusive goal,' says Steve Gundrum, who runs a company that develops new products for the food industry."

    Humidifying the air would require carrying many extra gallons (hundreds?) of fresh water.

    If you use a heat exchanger to warm incoming air with outgoing air, it should be possible to recover and reuse the moisture.

    Between ROTC and 10 years in the Guard I've experienced the last four generations of MRE. The late 80's / early 90's version was worthy of all the disdain ever heaped upon them. They've gotten progressively better though. Other than a residual slight metallic tang to the meat, current generation MRE's are by and large no worse than most fast food (which is not to say that they're good, just not nearly as awful). The vegetarian one's are actually better IMO, the lack of meat completely removes the metallic taste and they always have fruit and granola bars as extras. The fruit is no worse than any canned fruit and the granola bars don't suffer from the heat as much as a lot of snacks.

    Don't get me wrong, I'm not saying that you want a regular diet of the things; but living on them for a couple of days isn't unpleasant anymore. No worse than a travel day where you're forced to eat more fast food than you'd like.

    Oh, and they come with chemical heater now. Activate the heater with a quarter cup or so of water and no more cold/frozen food. The second and third generation had the heaters as an optional extra item the unit could get along with the MRE; but now they're packed inside the bag. There's less chance of a screw-up or sadistic supply sergeant that way.

    That would be nice if you could direct the outgoing air through an exchanger. It leaks out through bad door seals and other unintended openings. And it takes the moisture with it.

    The vast majority of air "leaks" out through cabin pressurization valves near the back of the plane - it's designed that way since air has to be let out in order to let fresh air in (as well as to not keep the cabin at the same altitude as the departing airport - to climb up to 8000' requires releasing air).

    My understanding is that exactly the opposite happens. Because of adiabatic heating, the air being compressed into an aircraft cabin actually needs to be cooled (it's bled off of compressors for the jet engine). At least, that's what I've been told by a few people.

    Correct. The pressurized air for the cabin comes from the jet engine's bleed air (located after the compressor section). It's quite warm because of the compression (from -30-50C to +50-60C), so it needs to be cooled down via air conditioners to levels humans would prefer.

    It's also one reason (among many) to keep the cabin at 8000' and why air quality has declined - using the bleed air saps power from the engine.

    That's correct in the vast majority of cases. The 787 being an exception, using dedicated electrically driven air compressors instead of bleed air to supply the cabin.

    The problem with outside air at 35K feet is that it is cold. So its absolute humidity is very low. Warming it up lowers its relative humidity even lower.

    Good food on an airplane isn’t an impossible feat. My taste buds work just fine on all altitudes I’ve tried them on. Food quality primarily depends on how little the airliner is willing to spend on it.

    You're correct. The recommended daily intake of sodium is 2300 mg (2.3 grams). 1.5g is about 65% of that. Unless you are on a low-sodium diet, it is not completely outrageous for a single meal on a rare occasion, so long as you typically watch the amount of salt you'd consume in your other meals. The problem is that nobody does. Typical salt intake is ~5 grams per day.

    and below the 14,000 where you can't breath,

    This is incorrect. People in good health can breathe just fine at 14,000'. You will definitely feel more aerobically challenged for a given level of exertion. Many unacclimatized people will experience mild altitude sickness (headache), and a few will get sick enough that they need to descend immediately for safety.

    People routinely summit Kilimanjaro, which is 19,000', without supplementary oxygen -- in fact, I've never heard of anyone using oxygen at that altitude. The altitude where it's really impossible to breathe, even if you're healthy and thoroughly acclimatized, is more like 25,000' to 29,000' (the top of Everest). Some people do summit Everest without oxygen.
