Original title: General Administration of Food and Drug Administration scientific interpretation of how to prevent nitrite poisoning
According to the State Food and Drug Administration website news, recently, a rural self-hosted group banquet food poisoning incident caused by the misuse of nitrite occurred in Ba zhong City, Sichuan Province. What is nitrite? How harmful is excessive human ingestion? Recently, the General Administration of Food and Drug Administration issued a consumer warning, nitrite is a widespread class of nitrogen-containing inorganic compounds in nature, can be used as food additives in meat products, but in a short period of time the human body ingested excessive nitrite can lead to poisoning and even death.
it is understood that nitrite is a kind of nitrogen-containing inorganic compounds commonly used in nature and can be used as food additives in meat products. Common nitrites are mainly sodium nitrite and potassium nitrite, its appearance is similar to salt, white to pale yellow, powder or granular, odorless, salty taste, easy moisture and soluble in water. Under normal diet, nitrites in the human body are mainly converted from nitrates in food and water under the role of bacteria in the mouth and stomach. Studies have shown that nitrites can be reduced to nitric oxide in some way. Eating foods that contain low levels of nitrites supplements nitrites in the body.
national standards for food safety in China have strict requirements for the use and safety management of nitrites, in accordance with the standards of the use of nitrites is safe. The national standard stipulates that sodium nitrite and potassium nitrite can be used as color protectors and preservatives in the processing of cured meat products, soy sauce meat products and smoked, roasted and grilled meats, and provides for maximum use and maximum residue. Food service providers shall comply with the Notice on the Prohibition of the Purchase, Storage and Use of Food Additives nitrites by Food Service Units (Ministry of Health Notice No. 10 of 2012): The purchase, storage and use of nitrites (sodium nitrite, potassium nitrite) are prohibited.
if a short period of time through oral intake (mistaken or excessive intake) of a large number of nitrites, it is easy to cause acute poisoning and even death. There are four common causes of food poisoning caused by nitrites. First, because nitrites are similar in appearance to salt, the misuse of nitrites as salt or consumption is the main cause of poisoning. Second, because many areas of our country have home-made processed meat products habits, if the consumption of meat products containing excessive nitrites will also cause food poisoning. Third, the content of nitrates in vegetables that have been stored for too long, rotted or cooked for too long and have just been pickled will increase, in which case consumption can easily lead to poisoning. Fourth, the well water in individual areas contains more nitrates (called "bitter well water"), with this kind of boiled rice if stored for too long, nitrates under the action of bacteria can be reduced to nitrites lead to poisoning.
The General Administration of Food and Drug Administration has prompted consumers to buy salt sold through formal channels. Pay attention to eat fresh vegetables, do not eat too long storage or bad vegetables. Eat leftover cooked vegetables can not be stored in the high temperature for too long, the best meal is ready to eat. Try not to use "hard well water" cooking, have to use time, should avoid long-term storage. In addition, when eating processed meat products, pickles and other foods, can be paired with foods rich in vitamin C, tea polyphenols and other ingredients to reduce the toxicity of nitrites may be contained.
