Peeling method: pesticide residues in vegetables and fruits are mainly concentrated on the surface. Peeling is a good way to remove residual pesticides. Don't be too troublesome or afraid of nutrient loss. Apple, pear, kiwi fruit, carrot, wax gourd, pumpkin, zucchini, eggplant, radish, etc. You should try to peel it.
Alkaline water immersion method: the main pesticide that pollutes vegetables is organophosphorus pesticide, which is insoluble in water, but decomposes rapidly in alkaline environment, so this method is one of the effective measures to remove pesticide pollution and can be used for all kinds of vegetables and fruits. The method is as follows: firstly, clean the dirt on the surface, soak it in alkaline water (500ml of water and 5- 10g of edible alkaline noodles) for 5- 15min, and then rinse it with clean water for 3-5 times.
Soaking and cleaning with clear water: This method is the most basic and commonly used method to remove dirt and pesticide residues from vegetables and fruits. It is mainly used for leafy vegetables, such as spinach, day lily, leek flower, lettuce and Chinese cabbage. Generally, the dirt on the surface should be washed off with water first, and then soaked in clear water for not less than 10 minute. Fruit and vegetable cleaning agent can promote the dissolution of pesticides, so you can add a little fruit and vegetable cleaning agent when soaking. Rinse with running water for 2-3 times after soaking.
Storage method: As time goes on, pesticides can be slowly decomposed into harmless substances in the air, so fruits and vegetables such as apples, kiwis and wax gourd, which are easy to store, can be stored for a period of time to reduce pesticide residues. Generally stored 15 days or more. It is suggested that you don't eat freshly picked and peeled fruits right away.
Heating method: the decomposition of carbamate pesticides can be accelerated with the increase of temperature, so some vegetables and fruits that are difficult to treat by other methods can be removed by heating. Commonly used in celery, spinach, Chinese cabbage, cabbage, green pepper, cauliflower, beans and so on. First, clean the dirt on the surface with clear water, put it in boiling water for 2-5 minutes, and then rinse it with clear water 1-2 times.
Ozone disinfection method: connecting the ozone generator with tap water and washing vegetables and fruits with ozone-treated water can remove residual pesticides.
