I camp backcountry a lot, I mean for months at a time, and just never put food waste or smelly anything in my spare tire bag. I keep it for recyclables, other trash, and kindling etc, but nothing that would attract critters.
After awhile you learn how to minimize food waste from meal prep and after meals, and to keep it in a zip lock or simply in a small trash bag inside your vehicle over night or if away from camp. I like the biodegradable bags you can get your groceries in at some stores, but Walmart and big chain grocery store bags work, too. After leaving food waste in a bag locked in my trailer one night and having coons chew the hell out of the thick rubber gasket on my tonneau cover at the tailgate, I've never left it anywhere but in my vehicle at night.
I hang the bag on my rear door handle opposite my fridge and have made it a habit to put all organic waste in there as I create it, from coffee grounds, to cut off vegetable ends, to meat trimmings, etc. If you have it longer than you can get to a good place to dump it, squeeze all the air out, tie up the top and put it in another bag and tie that, too. I've never had a problem with it that way, odor, critters, or otherwise.
And DON'T throw orange peels, apple cores, potato peelings or any other food scraps into the woods or desert thinking animals will eat it. It is not their natural food, messes with their digestive systems, and attracts them to areas they would not go otherwise. Raccoons, bear, and coyotes have become nuisance animals in some places from careless campers throwing food waste around camp. Takes a hell of a long time, too, for things like orange peels to decompose.
