After starting on solid foods, babies can hardly go a day without fruits and vegetables. The fruits and vegetables on the market, with their vibrant reds and greens, are very tempting, but mothers can't help but worry: with such good-looking produce, how much pesticide residue do they actually contain?
In fact, there's no need to worry too much about this issue. China's "Law on the Quality and Safety of Agricultural Products" clearly stipulates:
The following types of agricultural products shall not be sold:
Those containing pesticides, veterinary drugs, or other chemical substances prohibited by the state; those where the residues of pesticides, veterinary drugs, and other chemical substances, or the content of heavy metals and other toxic and harmful substances, do not meet the quality and safety standards for agricultural products.
Generally, fruits and vegetables that enter the market through formal channels have been inspected and are relatively safe.
Wash Your Vegetables This Way and Never Worry About Pesticide Residue Again
Of course, it cannot be denied that incidents of excessive pesticide residue in agricultural products are still found. In addition to ensuring we purchase our daily ingredients from formal channels, we also need to know how to wash fruits and vegetables to minimize pesticide residue to the greatest extent.
Method 1: Peeling
The surface of fruits and vegetables tends to have a relatively higher amount of pesticides. Peeling is the simplest and most effective method.
Note: If the surface is not rinsed clean of dirt, it will cause the dirt on the peel to directly contaminate the flesh. Therefore, be sure to thoroughly rinse the surface of dirt before peeling.
Method 2: Blanching with Boiling Water
Blanching vegetables in boiling water can remove most of the pesticide residues from their surface.
The method is: first, rinse the surface of the fruits and vegetables with clean water; then, put the fruits and vegetables into boiling water to blanch them briefly, and then remove them; finally, rinse them once more with clean water.
Note: It is best to open the lid during heating to allow the pesticides to volatilize with the steam. Additionally, this high-temperature method is suitable for more heat-tolerant vegetables, such as cauliflower, green beans, bell peppers, and celery. However, common leafy green vegetables lose a large amount of vitamin C after heating, so this method is not suitable for them.
Method 3: Soaking with Baking Soda
Baking soda is slightly alkaline and can neutralize some acidic pesticide residues, thereby reducing the amount of pesticide on the surface of fruits and vegetables. Therefore, baking soda is also quite effective at removing pesticide residues.
When washing fruits and vegetables, you can put 10 grams of baking soda into 500 ml of water (increase the amount of baking soda and water proportionally), put the fruits and vegetables in, ensuring the water covers them, and soak for 15-20 minutes. After soaking, rinse the surface of the fruits and vegetables thoroughly with running water.
Method 4: Thorough Rinsing with Clean Water
This is the most common method for removing pesticide residues and can wash away some water-soluble pesticides. Furthermore, even if some pesticides are not water-soluble, the process of rinsing with clean water can wash away most of the pesticide residue, thus reducing the amount on the surface of the produce.
In terms of effectiveness, the four methods mentioned above rank as follows:
Peeling > Blanching with Boiling Water > Soaking with Baking Soda > Thorough Rinsing with Clean Water.
Mothers can choose the most suitable washing method based on their actual situation.
Additionally, you might think of many other folk methods for removing pesticide residues, such as using fruit and vegetable cleaners, soaking in salt water, or soaking in rice water (flour). Let's analyze why these methods were not recommended above:
◇ Fruit and Vegetable Cleaners: Fruit and vegetable cleaners are themselves chemical products. Improper use may cause secondary residue. Moreover, no fruit and vegetable cleaner on the market has been proven to be effective and safe, so this method is not recommended by this author.
◇ Soaking in Salt Water: The effect of saltwater soaking on removing pesticide residue is generally poor. Furthermore, when the salt concentration is high, it can cause the cells on the surface of the produce to rupture, leading pesticides to seep inward. From this perspective, doing so is actually counterproductive.
◇ Soaking in Rice Water (Flour): This method is a bit wishful thinking. People assume that starch can absorb pesticides and draw them away from the surface of the produce. In reality, this method is not effective at removing pesticides and may also cause impurities from the rice water to adhere to the surface of the fruits and vegetables. It's better to just give them a thorough rinse with clean water!
