Salt And Ferrous Gluconate Added To Stabilize Color

Ferrous gluconate is a salt made from gluconic acid, which is produced by fermenting glucose. It is often added to foods along with salt to help stabilize the color of certain products, particularly those that are brined or pickled.

Manufacturers add ferrous gluconate to help maintain the desired color of foods like olives and pickles. It works by preventing color degradation, ensuring the product looks appealing to consumers. It is commonly found in pickled vegetables and other preserved items.

Ferrous gluconate is Generally Recognized As Safe (GRAS) by the FDA for use as a nutrient supplement and for color retention. It is a source of iron, an essential mineral. The WHO/IARC has not classified ferrous gluconate regarding its carcinogenicity. JECFA has evaluated it and set an acceptable daily intake. Evidence does not suggest adverse effects at typical intake levels.
