Farmers planting fruits and vegetables generally use pesticides in order to control pests and diseases. Pesticide residues in fruits and vegetables are inevitable. Pay attention to food safety such as fruits and vegetables, and it is getting more and more attention from residents. Method for removing pesticide residues from fruits and vegetables:
(1) Heating method. As the temperature rises, the carbamate insecticide is easily decomposed by heat, and the fruits and vegetables which are difficult to handle by other methods can be heated to remove the local pesticide.
(2) Alkaline water soaking method. Organophosphorus pesticides are easily decomposed in an alkaline environment. This method is an effective measure to remove pesticide pollution. Soak in alkaline water for 5-15 minutes, rinse with water for 3-5 times.
(3) Storage method. During the storage of vegetables, active substances such as oxygen in the air and enzymes in vegetables can react with residual pesticides to oxidize and degrade pesticides, reduce pesticide residues and reduce their toxicity. For easy storage, fruits and vegetables can be stored for a certain period of time to reduce pesticide residues.
