Not much point in worrying about all of that really. Chances are there are smells on the stuff you've brought along that you don't even realize are there. Bears are going to smell everything, what's inside your bag and what you've touched before you put the stuff in that bag before you even left home. If you washed your hands with a nice smelling hand soap or something and then go and put your items into the bag and head out, that smell will have rubbed off to some degree on that stuff. Same if you've eaten food, smells in your car, etc.

Best thing to do is obviously avoid bringing any applie pie scented candles and know how to react and protect yourself from a bear, as well as how to handle that kind of stuff on their turf.
