How to remove pesticide residues in vegetables and fruits analysis of pesticide residues in different vegetables and fruits

vegetables and fruits are our daily diet Rape is most likely to be polluted because of the strong resistance of Pieris rapae to insecticides. Cauliflower, strawberry and other fruits and vegetables with uneven surface have the most pesticide residues.

root vegetables such as green peppers, cucumbers, beans and radishes, as well as some thin skinned fruits and vegetables such as tomatoes, cherries and nectarines, have better pesticide residues, while root vegetables such as potatoes, onions, radishes, sweet potatoes and peanuts are relatively small because they are buried in the soil. But there are not absolutely no pesticide residues.

fruits and vegetables with special odor had the least pesticide residues. For example, fennel, coriander, pepper, kale and so on, have less diseases and insect pests and less pesticides. However, due to the insect pest of leek, leek maggots grow in the vegetable body, vegetable farmers are easy to irrigate the roots with high toxic insecticides, which is easy to exceed the standard.

therefore, if consumers want to buy healthy and safe food, they need to go to the regular market to buy, try to choose vegetables with low probability of pesticide residues, and choose less vegetables that are continuously harvested, such as bean, leek, cucumber, mustard and so on.

How to reduce

first, rinse and then soak.

when we buy some vegetables and fruits from the market, we must first wash them with clean water for several times. First, we want to clean some dust and dirt on the surface. Second, we can also clean those agricultural medicines that are easy to clean on the surface. Then soak in water for about five to ten minutes. This is to make the toxin that has penetrated into the surface of vegetables and fruits be discharged by soaking. Generally, the residual pesticide can be removed by this method.

second, wash with baking soda.

baking soda is actually edible alkali. This alkaline substance has a very good effect on removing pesticide residues. After you buy the fruits and vegetables, you can soak them in baking soda for about two to three minutes. This will make the pesticide residues on the surface react with baking soda, and then clean them with water, and the pesticide residues can be removed.

third, wash with rice washing water.

rice washing water is weakly alkaline like baking soda, so it also plays a very significant role in the removal of pesticide residues. Moreover, rice washing water does not contain other chemicals, so it is safer to use rice washing water to clean fruits and vegetables.

Fourth, wash the dishes before choosing them.

in fact, for the removal of pesticide residues, using different steps, its effect will be very different. For example, when we are cleaning, we should wash those things and then select the leaves or fruit stalks that we don’t want. In this way, we can avoid bringing pesticide residues into fruits and vegetables in the process of choosing vegetables.

fifth, blanch with boiling water.

in fact, this method is the most effective for removing pesticide residues, and it is also the most respected method by experts. Most of the pesticides on fruits and vegetables are used to kill insects, and this substance can be easily decomposed after high temperature. Therefore, scalding fruits and vegetables with boiling water is the best way to remove pesticide residues. However, this method also has a big defect. Many fruits and vegetables will wilt after high temperature, especially fruits. High temperature may also damage the vitamins in fruits. So if this is the case, the use of high-temperature scalding of the fruit, the original value of the fruit will be missing a lot.
