Recently, the State Development Planning Commission public consultation on the health Proposed foil for liquor, maximum usage of 0.02 grams per kilogram. A lot of people said he was surprised, gold wine really want to come. Foil can be used in food it? There are also concerns, the ancient known as "suicide by swallowing gold" rumors, will not eat gold damage a person's health?
First, the gold metal used as an additive in food is not a new thing.
Indeed, the international authority of the risk assessment organization, FAO / WHO Expert Committee on Food Additives (JECFA) in 70 of the last century - the 1980s show the results of the assessment, there is a small amount of gold metal in food applications, and is classified as a food additive, use is as edible pigment, but the use of volume and range of applications is very small. Due to the use of a very small amount, JECFA considered the gold does not create the risk of harm, no need to set safety value (ADI) [1].
In the EU, in 2013 the latest standard display, metallic gold can be used for some candy, chocolate coating, can also be used in some alcohol (liqueurs), the main purpose is to be used as a pigment (colour), the EU did not use it clearly limited provisions that can be used in moderation as needed [2]. In Australia and New Zealand, metallic gold can be used for candy decorations, this is generally not eaten directly, there is no specified it also allows for a number of low-alcoholic beverages and wine, limited edition of no more than 100 mg / kg [3] . Compare this value, my suggestion is still much lower limits.
In Japan, some local specialty is the foil and foil food, such as gold foil coffee, ice cream, sugar, gold and one cool cake.
Secondly, gold is used in white wine safe?
Many people say that the ancient "swallowing gold suicide," saying that the gold poisonous. Indeed, modern medicine has proved that gold is non-toxic, and ingestion of gold objects do not cause poisoning. Some from drinking wine containing a small amount of gold while death cases in ancient literature records, the most likely is a result of smelting technology is limited, the purity of gold is not high, contain other toxic contaminants, or someone in advance on the gold-coated poison. If the "suicide by swallowing gold", probably because gold products through mechanical stimulation, leading to gastrointestinal rupture, bleeding and other complications caused by this general need to swallow a large amount of gold.
Others believe that, from the nutritional point of view, gold is not essential nutrients. Indeed, gold is not essential nutrients. However, as long as do not eat gold eat more, it is both harmless also unhelpful. Stability of gold is very good, is not digested in the human body, it will not react, it has no nutritional value or taste after eating gold, it does not accumulate in the body, it will leave the body intact. The simplest way is to eat will be excreted with the feces of gold, gold is the same.
Of course, if you eat too much gold, and may affect digestion or cause gastrointestinal discomfort. Fuyang City Ying West had a woman because of the dispute with her ex-husband swallowed gold ring case, when doctors because gold is very heavy and can not be digested, it is difficult with the gastric motility is discharged into the intestines, stay in the stomach a long time will cause gastric mucosal damage, may cause severe bleeding. So, eat a lot of this gold can not digest things, there are still risks.
In this draft, the amount of liquor was 0.02g / kg, to drink a pound of wine before 0.01g gold, most people drink far less than this amount. Even drink this amount, the toxicity of alcohol is much greater than gold.
There is also concern that the "golden wine" will be very expensive. However, if you add 500 grams of liquor loaded only up to 0.01 grams of gold, according to the current market price of 99.99% gold price will be 200 yuan of raw materials, that is to say the cost of a bottle of liquor to add gold but more than 2 yuan money. Therefore, the actual cost plus gold is not high, however, may actually raise the price of marketing businesses, consumers or should be rational to buy.
Finally, just guard the Planning Commission draft, has not officially approved.
From the food additive approval process point of view, this is just a phase, if consumers are concerned, is not considered necessary, can express their views. Now additive approval very seriously "technology necessity" for this problem, there are two different opinions, that some people think "no" necessary, but some people think to add it anyway. So, it will depend on the reaction of the community, whether the final formal approval is difficult to estimate.
