1Yellow prussiate of soda Rating: Safe
Anticaking agent: Salt.
Some salt manufacturers add yellow prussiate of soda (sodium ferrocyanide) to salt when they crystallize it. The additive generates jagged and bulky crystals which resist caking. That mitigates the need for extra anticaking agents.
Although this additive contains cyanide, it is not toxic because the cyanide is tightly bound to iron atoms.
