>>21443839the salt isn't sodium chloride, but ammonium chloride.
it's more biting and pungent than salt, and it does smell like ammonia, but in a pleasant nose-clearing way, like a strong menthol drop.
i've had salmiak flavored candy drops and chewing gum before, and it honestly works as a replacement for mint, lemon or cinnamon in sugar free gum.
people who hate liquorice would probably hate talking to you after you freshened your breath with one of those, though.
the main reason why i think the chewing gum isn't more popular, is that it loses flavor quickly compared to menthol flavored gum.
maybe it's because the salmiak salt is water soluble, and menthol is an oil?
