Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue detection, in particular to a sampling device for pesticide residue detection. Background Technique

[0002] The development of agricultural industrialization makes the production of agricultural products more and more dependent on exogenous substances such as pesticides, antibiotics and hormones. The use of pesticides in agricultural products in China remains high. The unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting the safety of consumers' food. In severe cases, it will cause consumers to get sick, have abnormal development, or even directly lead to poisoning and death. In order to ensure food safety and the health of consumers, pesticide residue detection is carried out on agricultural products. During the detection of pesticide residues in agricultural products, sampling is one of the key steps. At present, when sampling, agricultural products are usually directly put into water for soaking, and then the soaking solution is obtained for detection. However, this method has many disadvantages. First, some agricultural products will float on the water surface, resulting in insufficient soaking, thus affecting the accuracy of sampling. Moreover, the agricultural products are relatively static in water, and the dissolution rate of substances on the surface of agricultural products is slow, which will affect the sampling efficiency.
