Why Plane Food Tastes Like Cardboard

Is airplane food really that bad, or is your brain just lying to you? At cruising altitude, two things happen to your senses. First, the extremely low humidity evaporates your taste buds' ability to function, similar to having a bad cold. Second, "sonic seasoning" occurs—the low-frequency hum of the jet engines suppresses your ability to taste sweetness and saltiness. To combat this, airline caterers have to "over-season" their food to levels that would be inedible on the ground. Interestingly, the savory flavor of tomato juice is unaffected by the noise, which is why it's the most popular drink in the sky. It’s not the kitchen; it’s the altitude. ✈️ TheAeroGraphyOfficial — uncovering the real science and hidden mechanics of flight.
