고도에서 음식 맛이 달라지는 이유

30

percent taste reduction

At cruising altitude, passengers lose approximately 30% of their ability to taste sweet and salty flavors due to low humidity and cabin pressure.

설명

Cabin pressure at cruising altitude is equivalent to an elevation of about 1,800-2,400 meters, and humidity drops to around 10-15%, drier than most deserts. These conditions cause nasal membranes to swell and dry out, significantly dulling the senses of taste and smell. Airlines compensate by adding extra seasoning to in-flight meals. Interestingly, umami flavor perception is largely unaffected, which is why tomato juice is disproportionately popular on aircraft.
