what's the deal with airline food?
Well, there are many explanations for the poor taste quality of airline food.
The loud noise in an airplane cabin can significantly alter our perceptions of taste. The noise makes sweet foods less potent and umami flavors (savory or meaty) more robust.
Also, the dry cabin at 30,000 feet can evaporate nasal mucus, and pressurization may cause membranes to swell. Both of these basically numb your taste buds while on a flight. Perceptions of sweet and saltiness drop by up to 30 percent during flight-like conditions.
So you see, the food isn't to blame. It's your silly body that you should be directing your animosity towards.
