Edible gold leafs are not the same gold leafs that used to decorate walls, furniture and valuable objects. Edible gold is not only made from genuine gold but also manufactured specifically for the food industry with strict safety standards; this means all the equipment are rubricated with vegetarian oil and not with toxic industrial oil.
BEWARE OFF: Cheap edible gold, is a sign it is NOT made from genuine gold, genuine gold is costly, usually the price for 50 imitation gold leafs = one genuine gold leaf.
Non-genuine gold (imitation) is made from zinc, resin and mixed alloy, plus made on machines that are rubricated with industrial oil, toxic and harmful to human consumption.
Generally, gold leaf from 22-24k is suitable for human consumption. Both the United States and the European Union authorised the genuine gold leaf for human consumption under food colouring # E175, and the genuine silver leaf under food colouring # E174). The leafs are so thin that they will disintegrate in your mouth instantly.
