How do you view the successive reforms in the salt industry? These problems and voices appearing? An article on the Internet mentioned that “there is a terrible additive in domestic table salt——potassium ferrocyanide.
” In life, when cooking food, the high temperature of edible salt may cause potassium ferrocyanide to decompose into potassium cyanide.

.
The online article also mentioned that "the salt provided for the Olympic Games and the World Expo and the salt for export do not contain potassium ferrocyanide
This rumor spread quickly on the Internet

In terms of nature, edible salt is relatively stable and its aqueous solution is neutral; the sodium nitrite contained in industrial salt is relatively stable under dry conditions, but can slowly absorb oxygen and be oxidized to sodium nitrate, and the aqueous solution is alkaline
