Current notice
In order to make food look more delicious, food processors often add synthetic pigments to food. However, due to the harm of pigment to human body, for the sake of national health, all countries in the world have strict management of food pigment, and a variety of synthetic pigments have been banned or strictly limited.
The well-known azo synthetic pigments are Sudan red, lemon yellow, sunset yellow and so on. These substances will be reduced to aromatic amines in vivo, causing oxidative damage to DNA. Driven by the huge economic interests, the phenomenon that synthetic pigments exceed the standard and the scope of use in China's food is frequently prohibited.
It is urgent to establish a rapid and sensitive method for the detection of azo pigments in food.
Next Thursday (April 2) at 10 a.m., Dr. Jiang Kezhi, mass spectrometry center of organosilicon chemistry and Materials Laboratory of Hangzhou Normal University, gave an online lecture, focusing on the non target detection of azo pigments and the accurate analysis of aromatic amine isomers.
