Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.
Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide , which has the formula K 4 Fe(CN) 6 .
The following anticaking agents are listed in order by their number in the Codex Alimentarius by the Food and Agriculture Organization of the UN. 341 tricalcium phosphate; 460(ii) powdered cellulose; 470b magnesium stearate; 500 sodium bicarbonate; 535 sodium ferrocyanide; 536 potassium ferrocyanide; 538 calcium ferrocyanide; 542 calcium ...
Because of the high stability of their complexation with iron, ferrocyanides (Sodium ferrocyanide E535, Potassium ferrocyanide E536, and Calcium ferrocyanide E538 [45]) do not decompose to lethal levels in the human body and are used in the food industry as, e.g., an anticaking agent in table salt. [46]
The safety of sodium ferrocyanide as a food additive was found to be provisionally acceptable by the Committee on Toxicity in 1988. [47] Other anticaking agents sometimes used include tricalcium phosphate , calcium or magnesium carbonates, fatty acid salts ( acid salts ), magnesium oxide , silicon dioxide , calcium silicate , sodium ...
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...

A solution of E101 riboflavin (also known as vitamin B2) Crystals of E621 monosodium glutamate (MSG), a flavour enhancer. E numbers, short for Europe numbers, are codes for substances used as food additives, including those found naturally in many foods, such as vitamin C, for use within the European Union (EU) [1]: 27 and European Free Trade Association (EFTA).
