In the process of growing vegetables and fruits, a layer of pesticides is often sprayed to prevent them from being attacked by pests. If you want to remove pesticides, you can soak them in water. Generally speaking, 30 minutes is enough. When soaking, you can add a small amount of cleaning agent. This method is only suitable for leafy vegetables, such as spinach, leeks, etc. 1. Add alkaline water

Many people buy a bottle of baking soda in the kitchen, because the main component of most pesticides is organophosphorus. This chemical substance will slowly decompose and lose effectiveness after encountering alkali. Therefore, you can wash the vegetables and fruits first and then rinse them with clean water. Soak in alkaline water according to a certain ratio for 15 minutes. After soaking, rinse with water about 5 times. This method of washing vegetables is suitable for all kinds of vegetables and fruits. Because this method is particularly simple and efficient, it is loved by everyone. 2. Can be scalded with boiling water

Some pesticides can be inactivated by heating. This method is suitable for spinach, lettuce, etc. You can boil the vegetables in boiling water for about three minutes, then take them out and wash them again, so that you will have cleaner and hygienic vegetables. Many people like to eat broccoli or cauliflower, because this vegetable is quite special, so before cooking this vegetable, it must be blanched in boiling water.

The rice washing water is acidic, and the pesticides on the vegetables are alkaline, so they can be neutralized by acid and alkali, making the pesticides slowly lose their effectiveness. This method can achieve the purpose of removing residual pesticides, because rice washing water is very common, and everyone can store the water when washing rice. Every time you wash vegetables or fruits, wash them in rice water several times. This method is welcomed by many people, but everyone should try not to store the rice water for too long, because it is easy to deteriorate. There are some nutrients in the rice water, which can be fully utilized when washing vegetables and fruits.
