Can food spoil in space?

Say you had a couple things. A piece of cherry pie, a banana, and a sandwich.

Taking out the temperature factor. Forget hot or cold.

Could the vacuum of space preserve food? No air and no moisture and no way for the bacteria to grow.

Would I be able to get those foods later and they’d still be fine?

How long do you think they’d last.

Please exclude other variables like the food getting hit the dust and other things. I’m mainly curious about the space part.
