In recent years, many consumers in China have concerns about the quality of domestically produced baby milk powder, and infant milk powder produced in Germany, New Zealand and other countries has become the first choice for parents, especially some well-known brand milk powder. In February of this year, a number of foreign media reported the milk powder test report of the German quality inspection agency. The information on the excessive levels of chlorate and perchlorate in dairy products made many consumers feel uneasy. The results of the evaluation indicated that the chlorate and perchlorate in a certain brand of milk powder exceeded the standard and exceeded the daily allowable intake set by the World Health Organization in 2007.
Milk can be involved in the cleaning and disinfection of various utensils during processing and packaging, and the most common disinfectant by-products, chlorate and chlorite, which are harmful to human health, are present in various milk products. The International Agency for Research on Cancer (IARC) has classified chlorite as a carcinogen and chlorate is a moderately toxic compound. Perchlorate is a new type of persistent pollutant that acts as a powerful thyroid toxin that causes metabolic disorders in adults. A large number of research results show that drinking water, milk, fish and so on are likely to be contaminated by these substances. Therefore, accurate detection of chlorate and perchlorate in milk is particularly important.
In response to this problem, Thermo Fisher released a detection program for chlorate and chlorite in dairy products, using ion chromatography ICS-2100 with tandem mass spectrometry system to establish simultaneous determination of chlorate and chlorinated in dairy products. Method of acid salt. The sample is analyzed after pre-treatment, which greatly reduces matrix interference and improves the signal-to-noise ratio and sensitivity of the analytical method. The method is applied to the simultaneous determination of chlorite and chlorate in milk samples, and has achieved good measurement results. For the detection of perchlorate in dairy products, Thermo Scientific also uses ion chromatography and mass spectrometry with a detection limit of up to 1 μg/kg, which fully meets the requirements for determination of perchlorate in other dairy products such as fresh milk and yogurt. .
