Healthy gold

? Recently, in order to attract consumers, a restaurant in Bogota, Colombia, launched a golden burger. The hamburger is sandwiched with a double layer of beef patties, and the surface is covered with five pieces of edible 24K gold foil, which is glittering. It is reported that the price of this golden burger is 2 1. 1 10,000 Colombian pesos, about RMB 392, which is about 12 times the price of ordinary hamburgers.

? China was the first to use the golden history to promote it. As early as the Qin and Han Dynasties, the rich in China had records of eating gold foil and powder. In modern times, eating gold foil is also very popular in Japan and Southeast Asia.

1983, the Codex Committee of Food Additives of the World Health Organization officially listed 9999 natural pure gold in the category of food additives and named it Tabeano. 3 10. In China, precious Chinese patent medicines such as Niuhuang Angong Pill, Niuhuang Qingxin Pill, Wuji Baifeng Pill and Dahuoluo Dan are all used as medicines with gold foil.

The edible gold foil we introduced is only one tenth of a millimeter thick, which has no concept for ordinary people. As a metal, it is opaque, but the edible gold foil is so thin that it is transparent to light, so even if it is described as "as thin as a cicada's wing", it is actually much thinner than a cicada's wing, and it will break under the tension of water, making it almost impossible to hold it by hand.

In recent years, with the improvement of people's living standards, the "wind of eating gold" has risen again. At present, gold foil is very popular in Japan and Southeast Asia. Gold foil dinner, gold foil wine, gold foil water, gold foil candy and gold foil cake have become high-end hot items in the market. In some big cities in China, "eating gold" is not only for health care, but also a status symbol. According to incomplete statistics, there are 3 1 enterprises producing gold foil wine in China. Some experts have analyzed that as people pay more and more attention to health, "vegetable money" is not only satisfied with the high-end consumer class, but is likely to spread to the "middle class" crowd. However, what criteria should "eat gold" be based on?

In recent years, the number of corporate customers who come to the company to buy gold foil as food raw materials has suddenly increased. However, because the company's products used to be mainly used for building decoration and never used as food raw materials, it is very confusing whether they can be used as food raw material sales enterprises. "Because gold is not good, it will eat people to death. Isn't there an old saying called' swallow gold and die'? " Later, the Gold Foil Factory consulted the government regulatory authorities and found that the Codex Committee on Food Additives of the World Health Organization officially listed gold in the category of food additives in 1983? [ 1]。 In this case, the gold foil factory began to sell to food production enterprises.

As an "imported" food, gold is not an ordinary brick, gold bar or gold ring. Gold used as food raw materials must be processed gold foil. According to legend, Ge Hong, an alchemist in the Jin Dynasty, created the gold foil process, which made pure gold undergo more than ten processes of fine processing, turning gold of different sizes into uniform gold foil as thin as cicada's wings, becoming a unique traditional process of the Chinese nation and being praised as "a must in China" in the world. This process can make a gold ring into a gold foil the size of a basketball court. Later, gold foil technology spread to Japan and overseas, becoming the world's gold jewelry processing technology and lasting for a long time. Gold foil is widely used in antique buildings, modern buildings, gold plaques and so on. For example, gilding the Buddha statue, gilding the carved beam, and gilding it for decoration. Because it is as thin as cicada wings, it is the best choice as a food raw material. But how much gold foil should I add to a ton of wine? How much gold foil can an adult eat at most a day? There is no way to talk about these standards, and it is urgent for relevant departments to make provisions through scientific research, because on the one hand, it is related to the health of the people, on the other hand, it is closely related to preventing profiteering and maintaining the normal market economic order.
