Yes it can do, it depends on the circumstances. Ordinary untreated food would rot if it was in a spaceship. 'Space food' eaten by astronauts tends not to rot, because it is treated and vacuum sealed.

If you mean 'will food rot in the vacuum of empty space?' then the answer is that it won't rot exactly as there is no air; but it will undergo chemical changes. Bombarded by the solar wind and cosmic rays it will likely become ~~radioactive~~ irradiated and disintegrate into more stable compounds and form a kind of dust.
