Can edible alkali be used to wash fruits?

Because all fruits and vegetables are sprayed with pesticides now, there are still some pesticide residues on these foods when we buy them. If we often eat foods with pesticide residues, it will cause diseases in the body. Some people like to use detergent to wash off the pesticide residues on the fruits when washing them. Although there are no pesticide residues to harm the body, the detergent residues can also endanger your health. So, how should we wash the pesticide residues on fruits? Can we use edible alkali?

Alkaline water soaking method: Organophosphorus pesticides decompose rapidly in an alkaline environment, so this method is an effective measure to remove pesticide pollution. Can be used for all kinds of vegetables, fruits and melons. The method is to first rinse off the surface dirt, soak it in alkaline water (generally add 5 to 10 grams of alkaline powder to 500 ml of water) for 5 to 15 minutes, and then rinse it with clean water 3 to 5 times.

In addition to washing fruits with alkaline water, you can also use the following methods to wash fruits to remove pesticide residues:

Soaking and washing method: The types of pesticides that contaminate vegetables are mainly organophosphorus insecticides, which are difficult to dissolve in water. This method can only remove part of the contaminated pesticides. However, water washing is the basic method to remove other dirt and residual pesticides on vegetables and fruits. It is mainly used for leafy vegetables such as spinach, day lily, leek, lettuce, Chinese cabbage, etc. Generally, rinse off the surface dirt with water first, and then soak it in clean water for no less than 10 minutes. Fruit and vegetable cleaners can increase the dissolution of pesticides, so a small amount of fruit and vegetable cleaners can be added during soaking. After soaking, rinse with running water two or three times.

Peeling method: There is a relatively large amount of pesticides on the surface of vegetables and fruits, so peeling is a better way to remove residual pesticides. Can be used for apples, pears, kiwis, cucumbers, carrots, winter melons, pumpkins, zucchini, eggplants, radishes, etc.

It is not difficult to see from the above introduction that alkaline water can be used to wash fruits, but after using alkaline water to wash fruits, you must rinse the fruits with clean water three to five times. This way, the fruits will taste healthier. In addition to washing fruits with alkaline water, you can also soak them in clean water, wash them with rice water, or peel them directly before eating.
