There is nitrogen but not zinc
when the food is exposed to oxygen for a long time rancidity occurs. for example, let us take the chips packet ; the packet is filled with nitrogen in order to prevent oxidation.
Blood urea nitrogen.
You stated that carbon dioxide and nitrogen are present, but you did not mention oxygen. Nothing burns without oxygen . . . If you expose limewater to carbon dioxide, it will get cloudy, but will not if you expose it to nitrogen.
