The countries of the world, especially the western developed countries have not only done a lot of investigation and research on the impact of pigments on human health, but also in the management of food coloring, the use of synthetic colors have strict regulations, a variety of synthetic colors have been banned or strictly limited use.

Other countries are more strict restrictions on the use of certain colors, especially azo pigments in food. According to relevant information, the variety of synthetic food colorings that can be used legally has been greatly reduced after efforts have been made.

China restricts the use of China also has strict restrictions on the addition of synthetic colors in food: all meat and its processed products, fish and its processed products, vinegar, soy sauce, fermented bean curd and other condiments, fruits and their products, milk and dairy products, baby food, cookies, pastries can not be used in the use of synthetic colors. Only soft drinks, cold foods, candies, prepared wines and fruit juices can be used in small quantities, generally no more than 1/10,000.

There are seven varieties of synthetic food coloring approved for use in China, namely amaranthine red, cochineal red, seductive red, lemon yellow, sunset yellow, indigo and bright blue. While the jury is still out on the dangers of these seven synthetic food colorings, they have no nutritional value and are not helpful to human health, so try not to consume them if you can.

In fact, in the huge economic interests of the drive, China's food in the synthetic pigment over the standard, over the scope of the use of the phenomenon of repeated, we must be careful when buying food, do not go overboard to pursue the color of the food.

Sweden, Finland, Norway, India, Denmark, France and other countries have long banned the use of azo pigments, including Norway and other countries have completely banned the use of any chemical synthetic coloring.

U.S. artificial coloring review than other additives strict: only 9 allowed to use

In the United States, synthetic coloring management than other food additives to be more stringent. Currently, there are only nine synthetic colors available in the U.S. for use in food, and one of them can only be used on fruit skins. Because different colors can be blended by several basic colors, so these few pigments are also enough. The safety standards for these colors were developed by feeding different amounts to animals, finding the maximum dose without any abnormalities, and taking 1% of this dose as the upper safety limit for humans. Then based on that upper safety limit, and the maximum amount of a particular food that people might consume each day, the maximum amount allowed in that food is determined. And the safety approval of coloring is done on a batch-by-batch basis. That is to say, for every batch of product that a manufacturer produces, they have to send a sample for testing, and it passes before it can be approved for sale by the FDA. And the FDA's approval is for that batch of product, not the kind of coloring the manufacturer produces, much less the coloring itself.

Britain found 6 kinds of colors affect children's IQ, the European Union banned sunset yellow lemon yellow, etc.

The latest British study found that the consumption of artificial coloring will affect the intellectual development of children. The study said that there are six kinds of toxicity comparable to leaded gasoline artificial coloring: sunset yellow, lemon yellow, light red pigment, Li Chun red, quinoline yellow and seductive red, some of the children have a certain impact, but the UK Food Safety Authority did not take immediate action after the report was published in September 2009, but at a cost of 750,000 pounds to request the University of Southampton to carry out further research; the results of the study show that consuming too much coloring may make the child IQ points. The results of the study therefore favored the UK to stand its ground and ask the European Commission to make a final decision on banning the use of these artificial colors. [Details]

Denmark bans coloring in basic foods, other coloring products must be labeled

Denmark is one of the world's most stringent requirements for the use of food coloring, and researchers in the country have suggested that instead of banning the addition of coloring to food products, it would be better to indicate the type of coloring added to the food labels. By doing so, consumers can make a decision on whether or not to buy the food. In addition, the Danish government has decided to ban the use of colors in basic foods and require that all added colors be indicated on food labels. Denmark has taken this action in order to ensure that those who are allergic to certain colors consume basic foods without coloring.
