To further understand why space food tastes bad, Loke had her subjects sample three different odors. The lemon, vanilla, and almond scents were tested by the volunteers in a normal environment and then inside the virtual reality environment. The participants were instructed to rate each scent on an intensity scale from 1 to 5 under both conditions.
Loke’s paper revealed that lemon scents were rated the same in both environments. However, almond and vanilla were remarkably more intense during the simulation. Loke and the other researchers surmise that this is due to the presence of an aromatic compound called benzaldehyde being found in these two foods. With that in mind, what does this discovery have to do with space food?
