Since the pesticide is mainly attached to the surface of fruits and vegetables during the spraying process, as long as the effective washing and processing methods are adopted, the residual amount of the pesticide can be reduced, and the edible safety of the vegetables can be ensured.
Soaking and rinsing with water can reduce the amount of pesticide residues, and the longer the bubble time, the less pesticide residue. Tests have shown that 15 to 60% of pesticide residues can be removed by soaking the vegetables with tap water for 10 to 60 minutes and then washing them a little. Soaking with a special vegetable and fruit detergent is more effective in reducing the adhesion of pesticides. Dilute the detergent in water at a ratio of 1:200 and soak the fruits and vegetables. Within 10 to 60 minutes, the pesticide residue can be reduced by 50%-80%; especially in the first 10 minutes of soaking, the pesticide residue is very obvious, which can be reached. About 50%. Then, wash it a little and rinse it off with water to remove the pesticide residue.
High temperature heating can also decompose pesticides, such as boiling water or oil. Experiments have shown that some heat-resistant vegetables, such as cauliflower, beans, green peppers, celery, etc., can be washed with boiling water for a few minutes, which can reduce the pesticide residue by about 30%, and then remove the vegetables by 90%. % of pesticides.
In addition, washing rice with rice and proper sun exposure can also play a role in reducing pesticides on vegetables. But the rice water is best used once or twice, because the surface of the rice contains potassium, so the first or twice of the rice water will be weakly acidic, but then it will start to change to alkaline, and the pesticide is only in the acidic substance. Will lose some toxicity. Sunlight can cause some pesticides in vegetables to be decomposed and destroyed. According to the measurement, the vegetables are exposed to sunlight for 5 minutes, and the residual loss of organochlorine and organic mercury pesticides can reach about 60%.
Vegetable peeling can of course also reduce pesticide residues, but it also causes loss of vitamins and minerals in the skin. Therefore, the best way to remove pesticides is to soak the fresh fruits and vegetables with detergent for 10-15 minutes, or soak them in tap water for 30-60 minutes, and rinse them with water.
