Washing vegetables in the wrong way for so many years!
This post has the best 5 tips to teach you to completely remove pesticides.
Many people’s habit of washing vegetables is to soak them for a period of time after washing to remove pesticide residues. Some people even soak the vegetables for 3 to 4 hours, but in fact, this may make the vegetables more soak and dirty, and reduce The nutritional content of the vegetable itself!
There are two types of pesticides, each with its own difficulties!
The current pesticides can be divided into two types: fat-soluble and water-soluble; since the permeability of fat-soluble is higher than water-soluble, most of the pesticides used in fruits and vegetables are fat-soluble, but it is also caused by the high permeability of fat-soluble Fat-soluble pesticide residues on the surface of fruits and vegetables are also much higher than water-soluble pesticides.
Therefore, if the fruits and vegetables are soaked in water, only the water-soluble pesticides on the surface can be removed, but the remaining fat-soluble pesticides cannot be removed. In addition, water-soluble pesticides have a certain solubility concentration in water. If they are soaked for a long time, it will cause the fruits and c to re-absorb the pesticides in the water.
How to wash vegetables and fruits correctly?
1. Cut after washing:
Washing will not cause excessive loss of nutrients in fruits and vegetables, and can improve the degree of removal of pesticide residues. In addition, vegetables should be washed and cut; on the one hand, water-soluble vitamins B, C, calcium, and magnesium can be reduced Oxidation or dissolution of iron, iron, etc., on the other hand, it can also prevent pesticides from penetrating the cut surface of vegetables.
2. Blanching (boiled):
Blanching is to wash the vegetables, put them in hot water and boil them for 1 to 3 minutes, and then take them out for cooking. This can help remove pesticide residues and harmful substances such as oxalic acid and nitrite.
3. Use food-grade detergent:
Washing with clean water can remove water-soluble pesticide residues, but for fat-soluble pesticide residues, you need to add 1~2 drops of food-grade detergent in the soaking water, and then soak the fruits and vegetables for 3~5 Minutes, then rinse with water for 1 to 2 times to thoroughly clean the fat-soluble pesticides.
For vegetables and fruits with thick skins like radishes or cucumbers that cannot be blanched, the peeling method can remove the pesticide residues remaining on the surface of the vegetables and fruits, and the removal rate can reach more than 90%.
5. Rinse with weak alkaline water:
Rice washing water, baking soda water and flour water are common weak alkaline waters in the kitchen. Pesticides are easier to decompose in aqueous solutions in alkaline environments, so the removal rate of pesticide residues can be improved.
