Why does a spoiled food smell linger even after cleaning?

Spoiled food odors stay trapped in the air and surrounding area even after you clean up the physical spill. This lingering smell makes it feel impossible to clear out the room, leaving the odor hanging around despite your best cleaning efforts.
