【Private message】I try to drink random tea samples
In recent years, China's tea has repeatedly encountered food safety problems, among which the problem of excessive pesticides in tea has been pushed to the forefront, which has aroused heated discussion in society and become the focus of everyone's attention.
Tea as a drink, has belonged to the category of food, if there is no strict standard of safety control, pesticides exceed the standard of tea, will definitely cause harm to the human body. On the contrary, pesticide residues that meet relevant national standards and are harmless to the human body have been criticized.
[ Pesticide residues in tea ]
What is the difference between pesticide exceeding the standard and pesticide residue?
How should we correctly view pesticide residue tea?
What are the relevant standards for tea in China?
With this article, you will find answers.
First of all, pesticide residue tea refers to tea with pesticide residues in the tea. In view of the problems mentioned above, let's analyze them one by one.
01
The difference between pesticide exceeding the standard and pesticide residue
Pesticide exceedance and pesticide residues are two concepts
Earlier, Chen Zongmao, academician of the Chinese Academy of Engineering, honorary chairman of the China Tea Society and vice chairman of the International Tea Association, has clearly stated:
Therefore, from the content of Academician Chen Zongmao, the key to defining whether it is pesticide exceeding the standard and pesticide residues lies in whether the amount of pesticide residues meets the relevant standards, and if it does not exceed the relevant standards stipulated by the state, then pesticide residue tea will not cause harm to the human body.
Therefore, there is a big difference between pesticide exceeding the standard and pesticide residue, and this difference lies in the amount of pesticide residues.
02
Relevant standards for pesticide residues in tea
China's pesticide residue standards are stricter than those of other countries
From the perspective of China's formulation of relevant standards, China is one of the countries with more pesticide residue standards in the world's major producing countries, such as the International Food Standard Codex, which involves 15 tea pesticide residue standards, and China has formulated 27.
Moreover, China's pesticide residue standards are stricter than those of other countries, such as: endosulfan, China's standard is 20mg/kg, Japan and the European Union is 30mg/kg.
China has also formulated strict hygiene standards for tea: in China's "Tea Hygiene Standards" GB9678-1988,
After the promulgation of the Food Safety Law in 2009, the Ministry of Health and the Ministry of Agriculture jointly issued 315 limit indicators, and the total number of pesticide residue limit standards in food reached 2319. For pesticide residues, China has issued a total of four national standards and formulated a total of 27 limit indicators.
It can be seen that China attaches great importance to food safety, and the standards formulated at the same time are very strict.
03
Can pesticide residue tea be drunk?
Tea that meets the standard vertebrae through tea quality testing can be drunk
Liu Xin, a researcher at the Tea Research Institute of the Chinese Academy of Agricultural Sciences, said:
In addition, pesticide residues are now generally detected organically, yet most pesticides are insoluble in water and have very low pesticide content.
Therefore, generally through the quality test of tea, tea that meets the relevant pesticide residue content standards can be drunk.
04
Is there pesticide residue tea in ancient tree tea?
The spraying of pesticides on ancient tea trees is not practical
First of all, most of the ancient tea trees in Yunnan generally grow in the deep mountains far from human habitation, inconvenient transportation, primitive environment, and grow for a hundred years, have innate advantages, have adapted to the surrounding ecological environment, rely on their own to resist pests and diseases, without the need to spray pesticides.
Secondly, during the growth of ancient tree spring tea, that is, before May every year, tea plants generally have no diseases and pests, so there is no need to use pesticides, and there are no pesticide residues in tea leaves.
In addition, ancient tree tea grows in the deep mountains with complex terrain, and most of the ancient tea trees have a large crown width and high tree type, and it is difficult to spray pesticides. And the labor cost is high, it is not cost-effective for tea farmers, so the probability of ancient tea trees playing pesticides is low, or even zero, coupled with the strict control of ancient tea gardens by local governments in recent years, tea farmers want to play pesticides is almost impossible, so the probability of authentic ancient tree tea having pesticide residue tea is extremely low.
In summary, although tea pesticide residues exist, as long as they meet national standards, they can be drunk. Of course, the premise is that when tea friends buy tea, they should buy it in regular brand stores and merchants.
