Environmental Working Group (EWG) recently released a list of 12 Dirty Dozen vegetables and fruits. Among them, strawberry still ranked first and became the dirtiest vegetable and fruit; Spinach jumped to second place. Let’s take a look at it with you.
48 Nearly 70% of the samples in three kinds of conventional fruits and vegetables were contaminated by one or more pesticide residues, down 6.6% from last year. USDA researchers found 178 different pesticides and pesticide decomposition products in thousands of agricultural products they analyzed. Some fruits and vegetables even have pesticide residues after washing. It is particularly important to reduce children’s exposure to pesticides& ldquo; Even low levels of pesticides are harmful to infants and young children. Parents should take measures to reduce children’s exposure to pesticides, while giving infants a diet rich in healthy fruits and vegetables& rdquo;
leafy vegetables are prone to pesticide residues exceeding the standard, because the resistance of cabbage insect is strong, common pesticides are difficult to kill pests, vegetable farmers will choose high toxic pesticides in order to kill pests as soon as possible.
how to reduce pesticide residues in fruits and vegetables has always been a topic of public concern. Today, I’ll teach you some tips to easily deal with pesticide residues in two minutes.
[take a spoonful of baking soda powder and soak it in water. The water turns yellowish. Then put the fruits and vegetables in and wash them. Soak them for 2 to 3 minutes
this method is time-consuming, easy to operate, and the price of baking soda powder is very low. It can be used for a long time for a few yuan to buy a bag, which can also be borne by ordinary families.
chemical principle
baking soda powder is actually sodium bicarbonate powder, the chemical formula is NaHCO?, Sodium is positively charged. If it is put into tap water, it will combine with the negatively charged chlorine in the water to form sodium chloride, which solves the problem of chlorine toxicity in tap water.
and hydrogen is positively charged. When it is added to water, it will combine with negatively charged water molecules and become weak alkaline water. Generally, most pesticides are acidic. Therefore, in addition to weak alkaline water and acidity, it can also accelerate the removal of pesticides attached to fruits and vegetables.
Alkaline water immersion method:
organophosphorus pesticides decompose rapidly in alkaline environment, so this method is an effective measure to remove pesticide pollution, and can be used for all kinds of vegetables and fruits. The method is to clean the surface dirt, soak it in alkaline water (generally 500ml water with 5-10g alkaline surface) for 5-15 minutes, and then rinse it with clean water for 3-5 times.
peeling method:
vegetables and fruits surface pesticide content is relatively large, so peeling is a better method to remove pesticide residues. It can be used for apple, pear, kiwi, cucumber, carrot, wax gourd, pumpkin, zucchini, eggplant, radish, etc. During the treatment, it is necessary to prevent the vegetables, melons and fruits from being mixed and polluted again.
heating method:
carbamate insecticides decompose faster with the increase of temperature. Therefore, for some vegetables and fruits which are difficult to be treated by other methods, some pesticides can be removed by heating. Commonly used in celery, spinach, cabbage, cabbage, green pepper, cauliflower, beans and so on.
wash the surface dirt with clean water, put it into boiling water for 2-5 minutes, and then rinse it with clean water for 1-2 times. According to the actual situation, the combination of the above methods will have a better effect.
fruits and vegetables are rich in vitamins needed by human body. It is good for health to eat them often, but pesticide residues are worrying. How to clean, in order to remove the pesticide residues on these fruits and vegetables?
In this way, the pesticide of vegetables is missing, and fruits and root vegetables
1 and balsam pear

carrot, potato and cucumbers, eggplant and other melon vegetables, it is suggested that peeling after cleaning is safer.
2, leafy vegetables
before cleaning this kind of vegetables, the peripheral leaves can be removed first, the root part should be cut off, and it is better to cut more part from the root, so that each leaf is scattered.
it is better to soak the internal leaves for 10-15 minutes. If the soaking time is too long, the pesticide will be absorbed again. After that, wash the leaves one by one with running water.
in addition, for the sake of safety, you can blanch water before cooking to remove most pesticide residues. The recommended time is 1-2 minutes to prevent nutrient loss.
3, fungi
because the bottom of the stipe with sand hard pedicle, even if the use of salt water bubble is not easy to wash, and difficult to digest. Therefore, this part should be removed before cleaning.
when cleaning, add salt in clean water, soak for a while, and stir the water clockwise, it is easier to wash off the residue between the gaps. Then rinse with clean water.
4, cauliflower
, such as broccoli, may have pesticide residues or insect attachment inside.
brush the whole surface of cauliflower lightly to remove the dust on the surface of cauliflower. Divide it into small pieces, soak in light salt water for 10-15 minutes, and then rinse with water.
Wash the fruit in this way, it’s easy and clean. Wash the mulberry with rice washing water. Wash the mulberry with rice washing water Strawberry and other granular fruit, the effect is good!
2, flour cleaning
add two spoonfuls of starch or flour into the water, and then shake the grapes back and forth to wash them!
3, salt water cleaning
peach surface capillary and more, how to wash off?
