Pesticide: For fruits and fresh vegetables, besides removing the peel and outer leaves, cleaning is the only way to reduce pesticide. However, it is not recommended to use detergent, because it may cause the problem that detergent can not be cleaned. Only when vegetables and fruits are cleaned can they lay a solid foundation for health and prevent diseases from entering through the mouth. So how should we wash vegetables?
Mistakes in cleaning vegetables
Soak fruits and vegetables in salt water? Not very desirable!
Relevant experts said that salt water does not have much effect on cleaning pesticide residues, but it can help remove pests in fruits and vegetables, such as cherry, cauliflower and other fruits and vegetables. For green leafy vegetables, salt water will destroy the cell membrane of vegetable leaves, not only losing nutrition, but also possibly allowing agricultural residues to enter the vegetables.
Use detergent, wrong!
Relevant experts said that the method of washing fruits and vegetables with detergent is not worth advocating, because detergent itself is a chemical substance, which may cause secondary pollution.
Raw meat washed under the faucet? Error!
The raw meat just slaughtered is relatively clean and has few bacteria, but there may be meat parasites, such as Taenia solium and Taenia saginata. Some people are used to washing the meat before cooking, but in fact, this is wrong.
The Department of Health of the Australian state of Victoria warned on its official website that after buying raw meat, do not wash it under the faucet.
If you wash the raw meat with the faucet, it will not only kill the bacteria on it, but also spread the bacteria to the kitchen - sink, chopping board, cooking table, kitchen knife... as long as the water splash is possible, the bacteria may spread.
If you wash fruit and other raw food next time, it may contaminate bacteria and cause food safety hazards.
Therefore, the Department of Health of the Australian state of Victoria suggests that raw meat should not be washed under the faucet, but can be fixed
Wash it inside, and then dip it dry with kitchen paper towel.
In addition, from the perspective of safety, except for organic meat, or meat with special knowledge of its source, it must be thoroughly cooked before eating.
Add vinegar in water, preferably alkali (baking soda)!
Relevant experts said that adding some vinegar or baking soda to the water would help wash out different kinds of agricultural residues more or less.
However, for common pesticide residues, the effect of baking soda may be better. It has certain effect on removing organophosphorus pesticide residues. However, it is necessary to control the concentration when using alkaline water to clean fruits and vegetables.
Method: Adding 10% edible alkali to clean water has the best removal effect, and the removal rate of dichlorvos can reach 76.11%. However, the effect of edible alkali concentration below 2% or more than 15% is the same as that of tap water.
You should know before washing vegetables
Vegetables cannot be cut before washing, but should be washed before cutting. The direct contact area between chopped vegetables and water will increase, and water-soluble vitamins such as vitamin B, vitamin C, some minerals and some water-soluble sugars in vegetables will dissolve in water and lose; At the same time, it will increase the chance of being contaminated by bacteria on the surface of vegetables, leaving health risks.
The correct way to clean vegetables and fruits
Meat: chicken, pork, beef, mutton
Cleaning method: Do not wash the raw meat under the faucet, but soak it in a fixed basin with water for 10 minutes, or blanch it with boiling water.
Fruit: It is recommended to rinse with water for 1~2 minutes, not only for a few seconds!!!
Cleaning method: first rinse with tap water for several minutes to remove surface pollutants, then soak in baking soda or rice washing water for three minutes to decompose pesticides, and then rinse again with clean water.
Cleaning method: first wet with water, then apply a handful of salt on the surface of the peach, then gently rub it, then put it in the water for a while, and then rinse it with water.
The viscosity of flour and starch can remove the white frost on the surface of grapes and the adhered soil.
Cleaning method: put the grape scissors into the water, pay attention not to cut off the grape stem, then put two spoons of flour or starch, pour back and forth for a few times, soak for a while, and then rinse with flowing water.
Stems and melons
Cucumber, green pepper, balsam pear
Cleaning method: You can put baking soda and soak it in warm water for 5 minutes, and then brush it with a soft brush, especially for the depression. You should brush it several times more, and then rinse it with clean water. If necessary, you can also wash and remove the skin.
Sweet potato, potato, radish, lettuce, loofah
Cleaning method: It is better to peel off the skin completely.
Foliage, Chinese cabbage, cabbage
Cleaning method: remove the outer leaves, clean the inner leaves with warm water, and then wash them with running water one by one.
Non-perishable vegetables: do not eat freshly picked and peeled fruits and vegetables immediately
Pumpkin, winter melon
In the process of storage, pesticides can be slowly decomposed into harmless substances over time.
Storage method: fresh vegetables can be stored in the air for 24 hours before eating.
Light irradiation method: part of pesticide residues in vegetables can also be decomposed by ultraviolet radiation in the sun.
Celery, cabbage, green pepper, cauliflower, beans
These vegetables generally use pesticides, which will accelerate the decomposition rate as the temperature increases.
Heating method: wash the dirt on the surface of these foods with clean water first, then put them in boiling water for 2~3 minutes and remove them, and then wash them with clean water for 1~2 times before frying or burning.
Cleaning method: first, wash the fruit with flowing tap water. The flowing water can prevent the pesticide from seeping into the fruit, and then soak it in baking soda for 5 minutes.
1. Do not take off the stem of the mushroom. If the stem of the mushroom is soaked in water, the residual pesticide will enter the fruit with water, causing more serious pollution.
2. Don't soak mushrooms with detergents such as detergent. These substances are difficult to clean and are easy to remain in fruits, causing secondary pollution.
Leaf and flower vegetables
Spinach, garland chrysanthemum, goldenrod, leek flower, lettuce, pakchoi, rape
Rinsing with running water+soaking method: the roots can be cut off, put in water for shaking and cleaning, remove the dirt on the surface through the impact and vibration of water, and then wash the upper half of the leaves with flowing water, and then wash the roots with upward flowing water. Repeat this for two or three times, then add baking soda to soak for 5 minutes, and then wash with flowing water for two or three times.
