Thai Page Warns Cheap "Edible Gold Leaf" May Be Industrial Foil
A Thai Facebook page warned consumers that cheap gold-colored foil imported from China and sold as edible bakery decoration may actually be industrial craft material containing unapproved metals, with tens of thousands of units already sold
CHIANG MAI — 25 May 2026, A popular Thai Facebook page has warned consumers that cheap gold-coloured foil imported from China and sold online as edible bakery decoration may not be safe for consumption.
The page, Drama-addict, said on Monday that a follower had alerted it to gold-coloured foil from China being sold at bakery supply shops as edible decoration. The concern began after the follower used a translation app to scan labels on small vials of the product.
According to the page, the translated label described the product as copper-based foil intended for arts and crafts, not for human consumption. Despite that warning, the item was allegedly being sold under edible baking supplies.
The page said similar products were also being sold on major e-commerce platforms, with some listings showing total sales of more than 10,000 units. The administrator purchased samples of the imported product and said the low price — about 20 baht per vial — was an immediate warning sign, as genuine edible gold leaf in similar quantities would normally cost far more.
After receiving the product, the administrator carried out several informal checks. He said genuine gold leaf is usually beaten so thin that it breaks apart and almost disappears when rubbed between the fingers. The sample, however, reportedly rolled into small clumps and metallic flakes.
The administrator also conducted a burn test, saying genuine gold does not oxidise when exposed to flame. When the imported foil was scorched, he said, it quickly turned black. The page said the reaction suggested the product was not genuine gold but another metal or alloy.
The page concluded that the product was not suitable for consumption and appeared to be intended for craft use. It accused some sellers of mislabelling the item online and in shops as "food-grade edible gold."
The administrator warned that consuming such products could pose a health risk, particularly if they contain metals not approved for food use. He said the apparent sales volume was concerning, with online listings showing tens of thousands of units sold.
It remains unclear how many consumers may have already eaten pastries decorated with the product. The page urged relevant agencies to inspect the products and take action before consumers are put at further risk.
