[ background of the invention ]

Food is a substance, usually composed of carbohydrates, fats, proteins or water, that is capable of providing nutrition or pleasure to a human or organism by eating or drinking. With the improvement of living standard and health care consciousness of people, how to improve the quality of food, reduce the residue of harmful substances in food, and ensure the quality and safety of food is an important task in the current food production and processing industry, food safety detection is to detect the harmful substances in food according to national indexes, and because the food safety is closely related to human life, in order to ensure that the life quality of people is kept in a healthy state, strict safety detection equipment is required to be provided for analyzing nutrient substances, harmful substances, nitrite and a general term of inorganic compounds. The nitrite is white to light yellow powder or granular, is slightly salty in taste and easy to dissolve in water, and is the most common nitrogen-containing compound in nature. Nitrate in human body can be reduced into nitrite and precursor substance of N-nitroso compound under the action of microorganism, and its appearance and taste are similar to those of table salt, and it is extensively used in industry and building industry, and also can be used in meat product as colour-developing agent with limited quantity. The probability of food poisoning caused by nitrite is high, the food poisoning can be caused by eating 0.3-0.5 g of nitrite, 3 g of nitrite causes death, the number of the death is 10-27.2017, and the precancerogen list published by the international cancer research institution of the world health organization is preliminarily collated and referenced, and the nitrate or nitrite ingested under the condition of causing endogenous nitrosation is in the class-2A carcinogen list. Nitrite is present in many food products and is a food additive which is allowed to be used in limited amount, mainly as a color former, a flavoring agent and a preservative in the food processing process. Nitrite has toxic effect on human body, and is mainly in the acid environment of human stomach, and is very easy to combine with amine to produce nitrosamine, and the nitrosamine is a kind of substance with strong carcinogenicity. Nitrite is not carcinogenic, but under cooking or other conditions, nitrite in meat can be degraded with amino acid to generate nitrosamine with strong carcinogenicity. Therefore, in order to protect the health of people, the detection of the nitrite content in food has very important practical significance.
