Title: Food perchlorate pollution has become a world problem. Our company's exclusive first perchlorate detection kit and special column (tea enterprises must see it for export)

Abstract: under the background that perchlorate was detected in China's tea exported to the EU, and the domestic detection research in this field is not mature, landhowbio's exclusive first perchlorate detection reagent filled the market gap, which is conducive to the timely self inspection of tea enterprises and finding out the response cases, so as to reduce the economic losses caused by perchlorate residues.

Chinese tea exported to EU was detected to contain perchlorate

Recently, perchlorate applied in modern aerospace industry has plunged China's oldest export agricultural product tea into a vortex. Recently, perchlorate, a "new pollutant", was exposed in China's tea exported to the EU. Perchlorate, which is often used in rocket fuel, military industrial production, fireworks and other manufacturing, is the "culprit" that has plunged Chinese tea into pollution. Data show that perchlorate is a high stability picture 2. PNG qualitative safe oxidant can cause thyroid dysfunction, especially has a great impact on infant metabolism and central nervous system, and may cause intellectual defects. Perchlorate has high solubility, low adsorption, strong flow diffusion and stability, and can persist in the natural environment and cause continuous pollution. Moreover, almost all perchlorate in tea can be dissolved in tea soup and drunk by people. Its residue problem is worthy of attention.

In a circular on the EU's formulation of the content standards of perchlorate and anthraquinone in tea issued by Sichuan Council for the promotion of international trade at the end of 2015, it was mentioned that the German Tea Association investigated a variety of tea samples and found that only all tea samples produced in China contained perchlorate. Relevant EU organizations are studying the reasonable content of perchlorate in tea and intend to set the mandatory standard of perchlorate content in tea as 0.75mg/kg.

Once the standard is formulated and implemented, China's tea export to the EU will be seriously hindered. Now tea exporters are very nervous. If the EU passes the perchlorate residue standard, it may have a great impact on their business. In 2014, China's tea exports to EU countries exceeded US $100 million. The marketing manager of a testing service company in Ningbo told reporters that since 2015, the content of perchlorate in the samples submitted by Zhejiang tea merchants has been increasing. The marketing manager of the above testing service company said that at present, the domestic customs will conduct sampling inspection on exported tea, and the tea products sampled will also detect the content of perchlorate. If the content is too high, they will be returned directly; However, this item has not been tested in domestic tea for the time being.

At present, the population research on perchlorate is mainly in the United States, but it is blank in China. The R & D institution of landhowbio of our company is just set up in the United States (Chicago). Many researchers have worked in world-famous universities such as Harvard University, Massachusetts Institute of technology, University of Chicago and FDA food safety center. Taking into account the blank of domestic commercial perchlorate detection market and our R & D level, landhowbio Recently, he exclusively launched the reagent kit and special column for the detection of perchlorate, filling the domestic gap, enabling tea export enterprises to independently detect perchlorate residues and enhance their self inspection and self inspection ability, so as to enhance the customs clearance ability and reduce the export risk of tea enterprises. Eventually

Drinking water, meat products and grains contain perchlorate, and the cause remains to be investigated

Although the recent emergence of "new pollutants" in tea has aroused public concern about perchlorate. In fact, perchlorate pollution is common in groundwater, drinking water, meat products, grains, fruits and vegetables, beverages and other foods, and perchlorate pollution to water sources is the most common. This is a worldwide pollution problem.

Behind the standard negotiation, the food industry is more concerned about the source of this "new pollutant". Liu Xin, a researcher at the Tea Research Institute of the Chinese Academy of Agricultural Sciences, told reporters that in fact, perchlorate will not be used in the planting of tea. Which link is involved, we still need to study and crack. The main sources of perchlorate pollution are aerospace, fireworks manufacturing, arms industry, rubber products, fuel coatings, etc. However, there is no scientific conclusion on how perchlorate enters tea through the above sources. Chen Zongmao, the only academician in the tea industry of the Chinese Academy of engineering and vice president of the International Tea Association, told reporters, "this is a new thing (pollutant), which has not been clarified yet." Luo Fengjian, an associate researcher of the Tea Research Institute of the Chinese Academy of Agricultural Sciences, also told reporters that for a long time, the research on tea pollution has mostly focused on pesticide residues and heavy metal residues, and the perchlorate appeared this time is a kind of pollution "New pollutants", the source of pollution has not been clearly determined. He plans to launch a thorough investigation on the main tea producing areas in China, "further investigate the source of pollutants by analyzing the general situation of perchlorate content in tea."
