What is safe to wash fruits and vegetables, and what is the best way to wash vegetables and fruits

There are many kinds of safe tricks for cleaning vegetables and fruits.

Trick 1: Peel off.

The surface of vegetables is waxy, which easily adsorbs pesticides. Therefore, vegetables that can be peeled should be peeled before eating.

Trick 2: Wash.

Generally, vegetables should be rinsed at least 3-6 times with clean water, and then soaked in lightly salted water and rinsed again. For cabbage vegetables, you can cut them first, soak them in clean water for 1-2 hours, and then rinse them with water to remove the residual pesticides.

Trick 3: alkali washing.

Put a teaspoon of alkali powder (sodium carbonate anhydrous) or glacial alkali (crystalline sodium carbonate) in the water and stir well, then add the vegetables. Soak for 5-6 minutes, pour out the alkaline water, and rinse with water.

If there is no alkali powder or glacial alkali, baking soda can be used instead, but the soaking time is appropriately extended, which generally takes about 15 minutes.

Trick 4: Wash with dish soap.

Dilute 300 times with dish soap and wash it once and then rinse it with water 1-2 times to remove germs, insect eggs and residual pesticides from the vegetables.

Trick 5: Blanch with boiling water.

The best way to remove some residual pesticides is to blanch, such as green peppers, cauliflower, beans, celery, etc., it is best to blanch it with boiling water before frying or burning in the pot, according to the test, it can remove more than 90% of the residual pesticides.

Trick 6: Sun exposure.

The use of multispectral effect in sunlight will decompose and destroy some residual pesticides in vegetables. In this way, the vegetables that have been dried by sunlight have less pesticide residues. It has been determined that the residue of organochlorine and organic mercury pesticides is lost by 60% when fresh vegetables and fruits are exposed to sunlight for 5 minutes

For vegetables that are convenient for storage, it is best to leave them for a period of time, and the oxygen in the air and the chromoenzymes in the vegetables have a certain decomposition effect on the residual pesticides. After purchasing vegetables, they are left at room temperature for about 24 hours, and the average disappearance rate of residual chemical pesticides is 5%.

In addition, washing vegetables with rice washing water can remove some of the pesticides that remain on the vegetables. At present, most of the organophosphorus pesticides such as methamidophos, phosphine, dichlorvos, and dimethoate are used to kill insects, and these pesticides will lose their toxicity when they encounter acidic substances.

Soak in rice washing water for about 10 minutes and rinse it with clean water to reduce the pesticide residue in vegetables.

No matter what vegetables you wash, don't use water, add a few more small things, and wash them clean and safe.

1.Light salt water: seafood can be washed.

For specific pesticide residues, solubility may be increased to a certain extent, but the effect is limited. Some vegetables that may have vegetable insects, such as cowpeas, cauliflower, shrimp, and shellfish, are washed with salt water to remove sediment.

However, if too much salt is added to the water, it will cause the cells of fruits and vegetables to shrink and destroy due to the increased osmotic pressure, and lose the original taste and nutritional value of the food. Therefore, if you want to remove pesticide residues in fruits and vegetables, light salt water is not advisable.

2.Rice water: It has adsorption effect but limited effect.

The rice washing water itself has a certain viscosity, which can adsorb some pesticides and chemicals attached to the surface of food, and remove vegetables, including grapes, mulberries, strawberries and other fruits that are not easy to clean. However, by increasing the particulate matter in the water and increasing the friction with the surface of fruits and vegetables, the effect is limited.

3.Flour water: decomposition of pesticide residues is inferior to rice washing water.

Flour water is similar to rice washing water in that it increases friction with the surface of fruits and vegetables by increasing the particulate matter in the water. This cleaning method is suitable for grapes, cherries and other small fruits and vegetables that are difficult to clean on the surface, but the effect is limited.

4.Fruit and vegetable cleaners: There may be a risk of secondary contamination.

Fruit and vegetable cleaners are also the choice of many people to clean vegetables. At present, among the most advanced fruit and vegetable cleaning agents on the market, many products are labeled as natural salts and surfactants, and some claim that the materials themselves are pure and natural, and they are refined by high-temperature processing, which can remove residual pesticides, bacteria, glazing agents and colorants on the surface of fruits, vegetables and other ingredients.

There are research experiments that compare the pesticide residue removal efficiency of common fruit and vegetable cleaning agents on the market with clean water, and the results show that clean water is as effective as them. Use fruit and vegetable cleaners, if the quality of the cleaning agent can be guaranteed. However, it should be noted that some fruit and vegetable cleaners may contain chemical ingredients, and if they are not cleaned, there may be a risk of secondary contamination.

5.Expert advice: one wash, two bubbles and three heating.

Experts suggest that we use running water rinsing and external friction to clean the water-soluble pesticides remaining on the surface of fruits and vegetables, and the friction can also remove the fruit wax on the surface of the fruit.

For some fruits and vegetables with smooth surfaces, such as apples, tomatoes, etc., the effect of soaking and cleaning is very good. Experiments have shown that after a short period of soaking, wash off. For some fruits and vegetables with rough surfaces, such as bitter gourd, green leafy vegetables, etc., soaking in water can also remove some pesticide residues.

More than 40% of the dish soap on the market may not be the kind of edible dish soap we say in our mouths, the chemical components in this dish soap are still more, sometimes using this dish soap to clean fruits and vegetables is equivalent to indirectly eating some of the chemical components inside, so the harm to the human body will be greater, so when we clean fruits and vegetables, we must think twice, not all dish soap is suitable for cleaning fruits and vegetables.

Personally, I think it is unsafe, in addition to washing off the dust on the surface of fruits and vegetables, it is necessary to wash off the residue of agriculture, and it is very likely that the detergent residue will not be cleaned, which is also unsafe.

Dish soap also has the function of removing stains, so it is safer to wash fruits with dish soap, and the best way is to rinse them off.

I think it's okay, the detergent is often used to wash dishes, of course, the end of the day to soak in water for about 10 minutes, so there is no problem.

It is not safe, because dish soap is also made of a lot of chemical agents, used to wash dishes and chopsticks and disinfect them, and the bad chemicals will definitely adhere to the surface of the fruit when washing the fruit, so that direct consumption is very harmful to the human body, so you must buy a professional fruit and vegetable cleaner to clean the fruit.

Safe, surfactants on dish soaps remove ingredients from pesticides.

It is safe to wash fruits and vegetables with proper use, but remember to rinse them with water several times. Prevent residues. Feel free to use detergent.

Safe, now there is a dish soap, which is specially used to wash fruits, and the ingredients in it are relatively safe.

In addition, some people use rice water to wash fruits and vegetables, because rice water is also weakly alkaline, which also helps to decompose pesticides such as organophosphorus. However, it is too troublesome to wash rice before washing fruits and vegetables every time.

If you must add something to clean fruits and vegetables, fruit and vegetable detergents are more suitable than the methods mentioned above.

Its active ingredient is a surfactant, which helps to remove pesticides that have penetrated into the waxy layer. However, it should be noted that when using fruit and vegetable detergents, you should pay attention to rinsing them well to avoid detergent residues.

Therefore, when using fruit and vegetable detergents, everyone will inevitably rinse several times. However, this can put a lot of stress on the ** of the hand. Long-term contact with water, ** will wrinkle; Wet hands aggravate joint pain in winter; If you have a wound on your hand, you can also get an infection.

So what should be done? Don't worry, as long as there is a mechanical manual vegetable washing basin washing machine, you can free your hands and easily wash away pesticide residues in fruits and vegetables.

<> number one: put in the salt or coarse salt we eat! Salt has the effect of disinfection and sterilization, which can make the skin of vegetables and fruits clean, but it should be put moderately, not too much.

Second: corn starch or sweet potato powder, these cores are composed of starch substances, take a basin of water, put vegetables and fruits into the water with corn starch to soak, after about 15 minutes, the dirt and dust outside will be discharged with the precipitation of starch.

Thirdly: baking soda can also be used, but the principle is the same as cornstarch! All of them can be soaked and discharged by soaking the dust and dirt to achieve the cleaning effect.
