What problems should be paid attention to during the food safety testing process?

The problem of excessive pesticide residues in vegetables and fruits frequently occurs, and it is more serious. In order to protect your health, everyone will be equipped with a pesticide residue tester. Now, pesticide residue tester is used to detect pesticide residues in vegetables and fruits. It is very normal and very frequent, but in the process of testing the food safety with the pesticide residue tester , there are several details we need to use more snacks and pay more attention.

1. Different instruments use different instruments, adhere to the appliance, and attach special labels.
2, the operation should be as fast as possible. Because the key to the detection of enzyme inhibition rate is the relationship between inhibition rate and reaction time, the control measurement and sample measurement operation time are inconsistent, and the detection result of pesticide residue rapid tester is also inaccurate.
3. In the process of detection, the reaction bottles, micropipettes, pipettes, etc. should be cleaned; especially after use, clean them and put them in a non-polluting place (such as filter paper, pipette rack, etc.) .
4. When using a pipette to suck the solution, press it properly, avoid pressing it all the way, and the tip should be cleaned in time.
5, the amount of enzyme, color reagent, substrate added should be accurate, shake after adding.
6. Grab the frosted surface of the cuvette with your hand and put it into the colorimetric slot of the pesticide residue tester. The light-transmissive surface should correspond to the direction of the light path, and let the light path pass through the transparent surface of the cuvette.

In the process of testing food safety with the pesticide residue tester, these small details have been noticed, so everyone's test is half successful. The details determine success or failure. Don't underestimate this little detail. It is very likely to determine the success and failure of your experiment. Therefore, we must pay more attention to these points, so that not only can the accuracy of the test be improved, but also the pesticide residue tester can be protected.
