Abstract

A method for detecting nitrate and nitrite in food comprises the following steps: performing sample pretreatment: fully mashing and uniformly mixing a food sample in a masher, carrying out water bathsuper-extraction in an ultrasonic dissolver, centrifuging in a centrifuge, standing, taking the supernatant, and filtering to obtain a liquid detection sample; performing nitrite content detection: inputting the liquid detection sample into a measurement system through a first measurement loop, and measuring nitrite contained in the sample; performing nitrite total amount detection: inputting theliquid detection sample into a measurement system through a second measurement loop, and measuring the original nitrite in the sample and the total amount of nitrite generated by nitrate reduction; nitrate content detection: determining the content of nitrate in the sample according to the difference between the detection result of the second measurement loop and the detection result of the firstmeasurement loop.

Description

technical field [0001] The invention relates to an automatic detection system, in particular to a detection system for nitrate and nitrite in food. Background technique [0002] As living standards improve. People's awareness of food safety is increasing day by day. Nitrate and nitrite are common pollutants that widely exist in various environmental media, and their harm to human health and ecological environment has been increasingly concerned by people. [0003] To make the food bright, a certain amount of nitrite or nitrate will be added to the food, such as meat, ham, fish products, dairy products, etc. Adding an appropriate amount of nitrate or nitrite can improve the flavor and make the color more attractive. In addition, the use of nitrate and nitrite can hinder the growth and reproduction of botulism in meat food, and no other additives have been found to replace the effect of nitrite and nitrate. [0004] Because the use of nitrite can improve the color of food ...
