I would imagine that anything that's in an airtight sealed container, such as chip bags, would be fine. That would also include cans. Your refrigerator and freezer, also, would probably count as a sealed container.

Smoke in a building fire can contain all sorts of weird chemicals from burning plastics and whatnot that could get deposited onto stuff, so even if you can't see any soot in your apartment I wouldn't dismiss all concerns. How tight is your budget?

I've worked in fire restoration. If there was smoke, there will be soot. You can take a white cloth and rub it over surfaces in the apartment to see how bad it is. As for food, the general rule is when in doubt throw it out. If cans are blown out from heat, toss them. If food was exposed to smoke, toss it. If the power was out for a long time, you may have to toss any refrigerated or frozen food. If there was no smoke in your unit you might be fine.

Feel free to dm me if you have further questions.

Only reading the title alone – I’m glad you’ve got your priorities right.

Seems you've gotten your answer, but leave an update after you eat and let us know how it went (and to make sure you didn't die :P )

Upholstery-soot ( the fire-retardent version of polyester, etc ), is evil smog/fumes.

If your food was sealed-away from the smog/fumes, then it should be fine.

I'm saying that after learning 1st-hand how evil upholstery-smoke is.

If you have to ask, you’re not hungry enough to take that risk. Toss those chips. Don’t take unnecessary chances with your body.
