Infobox references

Calcium ferrocyanide is a salt substitute, and was listed in 2012 by the EU as a "Food Improvement Agent". It is found at STP in the form of yellow crystals or crystalline powder.[1]

Uses

In the EU, ferrocyanides (E 535–538) were, as of 2018, solely authorised in two food categories as salt substitutes. Kidneys are the organ for ferrocyanide toxicity.[2]
