Nowadays, what is the most concerned about what to ask, then surely it is safe to eat. As an important environment for eating, agricultural products have long been subject to severe pesticide residue violations due to the pollution of pesticides. In order to provide agricultural products exceeding the standard, agricultural products provide a strong guarantee for people’s food safety. The pesticide residue detector has been widely used and applied in our country.
As an important part of food, agricultural products are contacted by people every day. Therefore, the safety monitoring of agricultural products such as fruits and vegetables is a major issue related to people's livelihood and economic development. Under this background, in recent years, the rapid detection industry for pesticides has developed rapidly. It is hoped that the industry will not be able to implement the pesticide residue tester. People hope that through such scientific detection methods, a transparent food safety road will be created.
In terms of appearance, the pesticide residue detector is not very attractive and its volume is not large. It is difficult to associate it with the image of pesticides testing using various test tubes and reagents in the laboratory. In fact, the function of the pesticide residue detector is not small. According to the principle of national standard enzyme inhibition rate, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase under certain conditions. The inhibition rate is positively correlated with the concentration of pesticides. Under normal conditions, the enzyme catalyzes the hydrolysis of the metabolite (acetylcholine), a neurotransmitter, and the hydrolysate reacts with a color-developing agent to produce a yellow substance. The absorbance is measured at 412 nm with a spectrophotometer over time to calculate the inhibition rate, which is inhibited. The rate can determine if there is a high dose of organic phosphorus or carbamate pesticides in the sample!
The existence of the pesticides residue has only one goal from beginning to end. It is to make people eat healthier and eat more reassured, and then bid farewell to the problems of pesticide residues. With the recent years, relevant departments have used pesticides to improve safety law enforcement, and the incidence of agricultural product safety accidents has been reduced. At the same time, the production companies or major planting bases have also begun to realize the economic value of green, pollution-free agricultural products, and actively started to apply self-tests with pesticide residue detectors to effectively ensure the safety of people's tongue and promote the sustainable development of agriculture. And the stability and prosperity of society.
