Residual pesticide testerThe role it plays in food safety
Frequent incidents of excessive pesticide residues in vegetables and fruits have raised concerns about food safety. For most of us, we don't know how to distinguish whether vegetables contain pesticides, so in the purchasing process, we rely on our own feelings to make purchases. If you don't know how to identify which vegetables contain pesticides, then you can use a residual pesticide tester for testing. This way, in a short period of time, you can know whether the vegetables you purchase are healthy and safe. What should we do if we buy vegetables containing pesticides? Don't worry, the residual pesticide tester teaches you a little trick to deal with pesticide residues.
We purchased vegetables whenResidual pesticide testerWhy do we use warm water to clean vegetables when determining their pesticide content? We are afraid of not being able to wash vegetables thoroughly, and our biggest concern is the organic phosphorus in pesticide residues. This substance is easily soluble in water and accelerates dissolution with increasing water temperature. At the same time, the amino acid ester insecticides in pesticides also accelerate decomposition with increasing temperature. Therefore, warm water is easier to remove pesticide residues on the surface of fruits and vegetables than cold water.
We have different methods when using warm water to clean different vegetables and fruits. For example, when cleaning vegetables such as cabbage, we can remove the outer leaves and soak the inner leaves in warm water before rinsing each piece with running water. Leafy green leafy vegetables such as spinach and bok choy can have their roots cut off, shaken and washed in water, and then rinsed with running water. As for cucumbers, green peppers, carrots, etc., they can be soaked in warm water for one to two minutes and then brushed with a soft brush. When purchasing vegetables containing pesticides, different vegetables have different cleaning methods, but before purchasing, it is still necessary to use a residual pesticide tester for testing, which is more reassuring.
