A recent, world-first study looking into common food aromas may explain why astronauts claim meals taste bland in space and find it difficult to fulfill their nutritional needs.
Researchers at the Royal Melbourne Institute of Technology (RMIT) in Australia found that spatial perception can greatly impact how people smell different aromas and, in turn, taste various flavors. Amongst astronauts, a greater sense of loneliness and isolation while on the International Space Station (ISS) can influence how they smell and taste their food, the study reported.
