Why does Airline Food Taste Bland?
Airline food tastes bland primarily because high-altitude cabin conditions temporarily dull your senses of taste and smell—not because airlines forget to season their meals. The Physiological & Cabin Factors * Dry Cabin Air Dulls Your Sense of Smell: Flavor is roughly 80% smell. On some planes, your taste buds are about 30% less sensitive to sweet and salty foods. Aircraft cabins are pressurized to the equivalent of 6,000–8,000 feet above sea level, and the air has extremely low humidity—often less than 15% , which is drier than most deserts. This dries out your nasal passages and reduces the effectiveness of odor receptors, muting subtle aromas before you even take a bite. * Reduced Sensitivity to Sweet and Salty: Studies (notably by Germany's Fraunhofer Institute for Building Physics) show that simulated flight conditions reduce human sensitivity to sweet and salty flavors by up to 30%. Because salt and sugar are the primary flavor enhancers in cooking, their suppression make...
