The detection method of iso-vc sodium in food
2022-06-01
Sodium iso-VC is a common preservative in food additives. Compared with other preservatives, it is less harmful to humans, but when the content exceeds a certain concentration, it will also cause harm to the human body, so many quality inspections Departments will test its content in food

There are many detection methods for sodium iso-VC, which can be observed with the naked eye by direct color development, but this method generally requires the extraction of preservatives in food, and a color reaction will occur when the concentration of preservatives increases. Generally, the content of preservatives in food is relatively small. If you want to test the preservatives in food, it is generally necessary to pretreat the food, and concentrate the preservatives to a certain purity and concentration before testing.

In addition, high performance liquid chromatography is also a common detection method, but this method requires relatively sophisticated instruments, and standard substances are required for comparison during the detection process. For some high-precision high-performance liquid chromatographs, direct detection can be carried out without processing, but most liquid chromatographs also need to be concentrated for detection.
