How to wash vegetables is the cleanest? How to remove pesticide residues? solve

Nowadays, most vegetables use chemical fertilizers and pesticides, so it is difficult to remove pesticide residues without much effort when washing vegetables. Here are some experiences of removing pesticide residues from vegetables and fruits.

Methods/steps

Soak in clear water and wash several times.

For ordinary vegetables, you can soak them in clean water 15 minutes or so, then brush them and brush them several times to remove some pesticide residues on the surface.

Wash vegetables with edible alkali or salt water.

Because the pesticide composition is mainly acidic, add edible alkali when washing vegetables, soak for five or six minutes (don't soak for too long), and then rinse with water. Eating alkaline noodles can neutralize acidic pesticides, and it will be safer to wash them several times, and the pesticides will be almost removed. For vegetables with thick skin, it can be washed with salt water, and the effect of removing pesticides is better.

Blanch the vegetables with hot water.

Cauliflower, celery, green pepper, beans and other vegetables can be blanched with hot water before eating, taken out and washed once or twice, which can accelerate the decomposition of carbamate pesticides with the increase of temperature, thus effectively removing pesticide residues. Be careful not to use too much hot water, which will easily destroy the nutrients in vegetables.

Peeling to remove pesticide residues.

For root vegetables, peeling is a better way to remove residual pesticides, because there are relatively many pesticides on the uneven or hairy surfaces of melons and fruits, such as wax gourd, apples, pears and cucumbers. Therefore, you can peel the skin as much as possible before eating, but you should pay attention to cleaning it before peeling to avoid the pollution of pesticides on the leather knife to fruits and vegetables.

Correct use of fruit and vegetable detergent.

At present, some food washing, fruit and vegetable detergents, etc. It is advertised that it can effectively remove pesticide residues in vegetables and fruits. Many people want to use it conveniently and often, but experts believe that the so-called fruit and vegetable detergent can only play a certain role. If used excessively or too frequently, it will cause secondary pollution and should be used with caution. Use a small amount each time, and the soaking time should not exceed 20 minutes. In addition, be sure to rinse it clean.

Let more vegetables and fruits bask in the sun.

Related studies have proved that the ultraviolet rays of the sun will have a spectral effect on vegetables, which will cause some residual pesticides in vegetables to decompose, inactivate and destroy. Therefore, letting vegetables bask in the sun can remove residual pesticides to a certain extent.

Leave it for a period of time to reduce pesticide residues.

Some pesticides will slowly decompose into harmless substances over time during storage. Therefore, for those vegetables that can be stored for a long time, leave them for 3-5 days after purchase, and then wash them with alkaline noodles several times to minimize pesticide residues.
