Do you know the food expert with illegal additives sodium thiocyanate
Date: 2015-02-15

Zhang Yan, forensic postdoctoral director of the National Environmental Quality Supervision and Inspection Center, Assistant Dean, Hebei Province, Food Quality Supervision and Inspection Institute assistant.
What is sodium thiocyanate
Sodium thiocyanate is a white orthorhombic crystal or powder, soluble in water, ethanol, acetone. Mainly used for chemical analysis reagents, color film, rinse agent, pharmaceutical, printing and dyeing.
Sodium thiocyanate and disable the use of history
National standard "food additives health standards" GB 2760-1986 1986 version that had to be included in the permit the use of food additives, mainly used in combination with hydrogen peroxide fresh raw milk, Heilongjiang, Inner Mongolia region. Then because of its toxicity, in GB 2760-2007 deleted this provision.
December 2008, the Ministry of Health issued "non-food substances in food may be illegal and easy to add a list of food additives abuse (first)," defined sodium thiocyanate are illegal to add non-food substances.
Why add sodium thiocyanate in food
In the 1980s, when the collection of milk and be transported to the processing plant is not yet possible due to conditions commonly used cooling facilities. In this context, in order to temporarily save the milk and the use of chemical preservatives is a compromise. Since 1986, one after another, sodium thiocyanate associated with hydrogen peroxide to form study reported fresh milk peroxidase system.
In 1995 the state has promulgated a national standard GB / T 15550-1995 "activation milk stored fresh milk lactoperoxidase system implementation specifications", because of its safety has been controversial, as the country's emphasis on improving food safety and progress and raw milk cold chain transport in China's economic conditions continue to improve, in October 2005 abolished the national implementation of the specification. However, even to the 2008 domestic as well as the use of fresh milk thiocyanate conducted research articles published. Also there are some criminals in order to make profits, regardless of national laws and regulations, still to add sodium thiocyanate in milk, endangering the health of consumers.
What are the hazards of sodium thiocyanate
Sodium thiocyanate toxicity in humans mainly by the release of cyanide ions caused. Cyanide ions can quickly and cytochrome oxidase in the ferric ion binding in vivo, inhibiting the enzyme activity, so the organization can not use oxygen. The main clinical symptoms of nervous system depression, metabolic acidosis and cardiovascular system instability.
Sodium thiocyanate method for detecting and monitoring
There is no food in the detection of sodium thiocyanate national standards or industry standards, the Ministry of Health Food Regulation Office [2009] No. 29 "on the issuance of the national fight against illegal to add non-food substances and the abuse of food additives rectification work sampling guidelines and programs notice "recommended reference method" Ion chromatography thiocyanate in milk. "
In the supervision and inspection of the country risk monitoring carried out by the various administrative departments, and dairy products are the sodium thiocyanate as an important monitoring object. However, due to environmental pollution and other reasons, dairy products contain trace amounts of thiocyanate root end. Strengthen the milk and dairy products in the basic data research thiocyanate and the background value monitoring, environmental pollution and illegally added to distinguish between effective regulation is necessary to carry out dairy products.
