does food rot in outer space, in a space shuttle? if yes/no, why? is there any experiments i can do to prove your point?

umm... in space no, because to rot, they need bacteria to develop, and for bacteria to develop you need oxygen.
Experiment???? Umm... put a high risk food substance in a bell jar (eg cheese or a dish of milk, any dairy is good) then vacuum out the oxygen and leave it for a week/month or so, then compare the results with one that hasnt been left in the bell jar, p.s. be careful when handling bacterialised foods as they are somewhat dangerous

Yes it does. That is why it needs to be specially prepared and packaged, to stay fresh even without a refrigerator, which the shuttle does not have.
Now if you are talking about food floating free in space and not inside the shuttle, then the vacuum of space might kill the bacteria that cause food to rot.

Having food in space is no different than having food in your refrigerator, and why would it be? You still have people (and all the bacteria they bring with them,) and conditions similar to those on Earth in terms of temperature and air pressure (because the astronauts could not otherwise live.) The only difference is the lack of gravity, which does not affect the bacteria or chemical reactions that make food go bad.
The main concerns with food in space travel is that it is light, compact, nutritional, and easy to prepare/eat in weightlessness.
