Gold (E175) — What You Need to Know

Current dataset status: FDA — Not specifically approved for food color (used in some products under GRAS); EFSA/EU — No ADI needed — inert metal, passes through body without absorption (2016 evaluation). Reported concerns: Pure gold is chemically inert and biologically non-reactive — it passes through the digestive system without being absorbed or metabolized. EFSA evaluated in 2016 and found no safety concerns, noting that gold is one of the least reactive chemical elements. Used primarily for decorative purposes in luxury foods. No known toxicity, allergenicity, or adverse effects. The main consideration is ensuring the gold used is of sufficient purity (typically 23-24 karat for food use) to avoid contamination with other metals. Regulatory status and individual risk are not the same; check the primary sources and permitted conditions of use.
