E175 - Or

Origin

E175, or Gold, as a food additive, is elemental gold (Au). It is a noble metal and is chemically inert. As a food additive, it is typically used in the form of very thin leaves or flakes. The gold used in food applications is of high purity.

Usage

Gold is used primarily for decorative purposes in food and beverages. It imparts a luxurious and visually appealing aesthetic. It is commonly found in high-end confectionery, chocolates, desserts, and beverages like sparkling wine. The amount used is typically very small, just enough to provide a visual effect. Gold is physiologically inert and passes through the digestive system unchanged.

Side Effects

Due to its chemical inertness, gold is considered to have very low toxicity when ingested in the form used in food. There are no known significant side effects associated with the consumption of gold as a food additive. It is not absorbed into the body and is excreted unchanged. Allergic reactions are extremely rare.

Regulatory Status

Gold is approved as a food additive in the European Union (E175) and is also permitted in other countries, including the United States. Regulations specify that it should be used in accordance with good manufacturing practices and only in quantities necessary to achieve the desired effect. There is no specific Acceptable Daily Intake (ADI) established, as gold is considered to be of very low toxicity and self-limiting in its use.
