Is it useful to wash fruit with salt? Wash the fruit with baking soda or salt

Salted washed fruits are usually useful. Some specific pesticide residues can increase solubility to a certain extent after being soaked in brine, but the effect is limited and it is easy to affect the taste of food.

Salt-washed fruits will have some effect.

Because some specific pesticides left on the surface of the fruit are soaked in salt water, they may increase the solubility to a certain extent, but the effect is limited, and it is easy to affect the flavor of the food.

Because the chemical composition of salt is relatively stable and not easy to react with other chemical components, the main effect of light brine is to dissolve protein, and it is difficult to effectively remove pesticide residues on the surface of fruits and vegetables.

Moreover, when washing fruits with brine, it is difficult to grasp the concentration of salt, and too high concentration of brine will cause the osmotic pressure of brine to be higher than that of fruits. As a result, the fruit loses water, and in severe cases, it will also lead to the rupture of some cells of fruits and vegetables, and pesticide residues will reverse osmosis.

Therefore, washing fruits with salt will have some effect, but it is necessary to grasp the concentration of salt to be used. You can use eggshell fruit and vegetable net, which is safer and more secure for eggshell fruit and vegetable net, and there will be no problems in use, because after eggshell fruit and vegetable net is modified by molecular cavities and heated and activated, the adsorption effect of its inner wall is greatly enhanced, and it has a good adsorption effect on pesticides.

At the same time, the bioactive calcium prepared by calcination of eggshells at high temperature has a strong decomposition and destruction effect on pesticides, and at the same time inhibits pathogenic bacteria, which can adsorb residual pesticides and pathogenic bacteria on fruits.

Washing fruits with salt water has the effect of disinfection and sterilization. Soaking the fruit in salted water before taking it out and eating it is conducive to sterilization.

Because there are bacteria on the surface of the fruit, if it is only washed with water, the cleaning effect may not be achieved.

Washing with brine can keep the fruit fresh and not easy to spoil, and can also inhibit the vitality of the fruit, especially some fruits with fine thorns or hairs on the surface, which may be gradually softened by the brine.

Washing fruit with salt has benefits such as removing packaging and destroying bacteria.

Because the fruit is packaged in plastic wrap, salt can remove the plastic wrap on the surface of the fruit, and it can also remove bacterial impurities, which is beneficial to human health. In addition, washing the fruit and adding salt can also remove the edible wax on the surface of the fruit, which can make the fruit more clean and hygienic.

Fruits are rich in sugars and proteins, as well as minerals and vitamins, which can supplement nutrients for the human body.

When washing fruits, you can use light salt water to clean, which can have a certain sterilization effect, and soaking in a short time will not produce adverse reactions, but if the concentration of salt water is too high when soaking, and the soaking time is relatively long, osmotic pressure is usually formed, resulting in the pesticide residue on the surface of the fruit penetrating into the fruit, and there may be diarrhea, abdominal pain and other uncomfortable symptoms after eating.

Although salt-washed fruits can clean the harmful substances on the surface of the fruit, soaking the fruit in brine for a long time may cause dehydration of the cells in it, and the B vitamins and minerals in the vegetables will be dissolved in the salt water, destroying the nutrients in the fruit and leading to the loss of nutrients in the fruit.

Baking soda can remove pesticide residues in vegetables and fruits when washing, but at the same time, many vitamins and minerals in vegetables and fruits are not alkali-resistant, which will lead to the loss of nutrients. Pesticides are acidic, baking soda is alkaline, so baking soda can deduct pesticide residues on the surface of the fruit, and use baking soda and other alkaline water to clean the fruit to master the concentration, about 10% alkaline water removal effect is the best.

Some fruits can still be salted, such as lemons with salt to scrub, but the cleaning is not thorough, and it takes a lot of time. However, it is not suitable to use salt for fruits such as millennial fruit, cherry tomatoes, and sunshine roses, which on the one hand damages the taste and on the other hand, it is time-consuming and labor-intensive. Therefore, many people have to use Guotaotao to wash, Guotaotao can remove dust, stains, bacteria, insect eggs, artificial fruit wax, surface pesticide residues, easy to wash, save time and effort.

Both. After the skin of the fruit is soaked in water, put a little salt, and then hold the fruit with both hands and rub it back and forth, so that the dirt on the surface can be rubbed clean, and then rinsed with water.

Baking soda powder can effectively remove pesticides from the surface of the fruit. Dissolve baking soda in water, soak the fruit for a few minutes, and rinse with water.

After scrubbing with salt and soaking in baking soda for a few minutes, it is the safest way to remove dirt and debris from the surface of the fruit, and remove pollutants such as pesticides. This is a truly safe way to eat.

Baking soda: Baking soda generally refers to sodium bicarbonate. White crystalline powder.

It is odorless, alkaline, and easily soluble in water. It slowly decomposes in moist or hot air to produce carbon dioxide, which is heated to 270 and loses all carbon dioxide. In case of acid, it decomposes strongly to produce carbon dioxide.

Sodium ions are a normal requirement of the human body and are generally considered non-toxic. However, excessive intake may cause alkalosis, damage the liver, and induce high blood pressure.

Fruits are highly nutritious and loved by many people! But, do you know how to wash fruit to wash it clean?

Many people think that washing fruit is a very simple thing, and some people think that it is a very troublesome thing.

Wash with water, for fear that there will be pesticide residues; Wash with dish soap, but you are afraid that it will not be clean; I feel that it is too troublesome to clean with a special fruit and vegetable detergent......

How do you clean it? In fact, if the cleaning method is not correct, it may get dirtier and dirtier the more you wash it

A picture shows you some common ways to clean fruits. Borrow some daily necessities and food, and the fruits can be washed clean and safe.

Apples, peaches, pears

You can soak the fruit bubble in soda water for 5 minutes to remove pesticide residues, glue and other stains on the peel.

If you don't have soda water at home, you can rub the peel with salt grains before washing it with clean water.

Grapes, cherries

There is a lot of residue on the peel, and it can be cleaned by the method of starch water adhering to the stain.

Bayberry

It is easy to hide the eggs, and can be blistered with salt water.

For peeled fruits such as mangoes and oranges, wash them before cutting them.

For fruits eaten with the skin, you need to use salt, flour and other items.

Washing water washing method

Rice washing water is alkaline, decomposable pesticide residues and viscous, can adsorb chemicals on the surface of fruits, and can wash granular fruits such as strawberries and mulberries.

Lemon cleaning method

Spray the lemon juice on top of the fruit and let it stand for about a minute to wipe off, removing pesticide residues and leaving the lemon fragrance.

Flour washing method

The starch is viscous and can adsorb fruit residues, making it suitable for cleaning grape citrus fruits.

Salt water cleaning method

The pesticide residues of some fruits are acidic, some are alkaline, it is better to soak them in salt water, and you can also use salt grains to remove the fine hairs of the fruit skin.

Baking soda cleaning method

Baking soda has alkaline properties to neutralize pesticide residues on the surface of fruits, add 2 spoons of baking soda powder with a basin of water, soak the fruit in a prepared solution, and wash cherries, dates, etc.

It should be reminded here that it has been popular to use rice washing water to clean fruits and vegetables in the past, but as everyone knows, eating rice also has the problem of pesticides and insect egg residues.

In addition, there is usually only one pot of rice washing water, and the amount of water is not enough to wash away pesticides, and the vegetables are soaked in it, and a pot of rice washing water becomes a pesticide pool, which is dirtier than unwashed vegetables.

It should be effective, put a little salt into the water to wash the fruit, put the fruit and vegetables in it and soak it for a few minutes, which can kill insect eggs and remove pesticide residues. Soaking fruits in light salt water can also enhance the sweetness of fruits, remove astringency, and make fruits more delicious.

The main purpose of washing fruits and vegetables in salt water is not to disinfect and sterilize, but to remove pesticides。But in fact, more pesticides cannot be washed out with salt water, because the composition of salt is sodium chloride, and water molecules may interact with chloride ions and sodium ions respectively, and the cleaning effect is worse. Although salt water can make insect eggs and borers fall more easily, salt will reduce the cleaning ability of water, and if the concentration of salt is too high, it will form osmotic pressure, allowing sodium ions to enter vegetables and fruits, which can easily cause poisoning.

As for the circulating Internet rumors, refined salt will lock pesticides on vegetables and cannot be used to wash vegetables. Many housewives who used to believe that salt water can wash pesticides better, and have long been accustomed to adding scoop salt to the water, don't know what to do for a while. Actually, this statement is not trueFrom an expert's point of view, refined salt does not lock pesticides on vegetables, but washing with salt is not necessarily better.

Pesticides can be divided into water-soluble and oil-soluble according to their composition, water-soluble pesticides can be washed off with water As for the cleaning of oil-soluble pesticides, salt may play a role similar to vegetable and fruit cleaners, but there is little difference in their practical use Pesticides are also divided into contact and systematic, contact pesticides are sprayed directly on the surface of crops, most of which will be washed away by rain or decomposed by sunlight. Systemic pesticides are absorbed through the plant surface, stomata and roots, and then evenly distributed throughout the crop, and most of these pesticides are soluble in water. Therefore, experts say that as long as it is washed thoroughly, most of the residual pesticides can be removed, and it can be eaten with peace of mind.

If the public cannot properly grasp the concentration of salt water, wash vegetables and fruits with too concentrated salt water, and the osmotic pressure will be too high. Cleaning of fruits and vegetables is the only way to reduce pesticides except for peeling the outer leaves and peels. There are hundreds of cleaning methods circulating on the market, but according to the personal experiment of Dr. Lin Jieliang of Taiwan Chang Gung Hospital, the best effect is to wash with flowing water, and the results of this experiment are the same as that of Kong Fanhui, director of the Agricultural Inspection Center, who has tried baking soda, salt, detergent and other methodsThe conclusion is that clean water is the most effective in removing contact pesticides

It is very useful to wash fruits with salt, and can sterilize and disinfect with salt water, and can remove pesticide residues attached to the surface of vegetables and fruits.

Washing fruits with salt is useful. But it is only useful for pesticide residues. Some pesticide residues soaked in salt water may increase solubility to a certain extent, but the effect is limited and it is easy to affect the flavor of food.

It is difficult to effectively remove pesticide residues from the surface of fruits and vegetables with light salt water. When washing fruits with brine, it is difficult to grasp the concentration of salt, and if it is too strong, it will affect the taste of the fruit.

It is useful, because if you wash the fruit with salt, it can play a good role in sterilizing and cleaning the fruit, for example, it can kill the germs attached to the fruit well, and salt also has the effect of keeping the fruit fresh.

Because fruits and vegetables are now on, a large number of pesticides are sprayed with a large number of chemicals, so it is necessary to add salt, or some leaves, so that the residual pesticides can be cleaned, and there is no harm to the human body.

There are many fruits that are not alkaline and salt, and there is no way to wash them thoroughly, especially grapes and lemons, which are more difficult to clean, and you can wash them thoroughly by adding some salt. Flour can be added when washing grapes.

Because the fruit must be cleaned with salt or lye, because in this way the fruit can be thoroughly cleaned, and the bacteria in it must be killed.

Why do many fruits need to be cleaned with salt or lye? Because many fruits are fresh-preserved, they have preservatives. That's why you need to wash it like this.

Why many fruit cleaners have family members or meet, it is better to remove pesticides or fertilizers.

I know, this will combine some of the sweetness of the fruit, so that it is not so sweet, it will not be tired of eating, and many fruits are very nutritious.

Because it can be used in this way to wash off some of the wax or fluff on the surface of the fruit, it can also have a sterilizing effect.

In this way, some pesticides can be washed off, and they can be washed more cleanly, which is better for people's bodies after eating.

Salt water has a partial disinfection effect. Salt can also decompose substances such as preservatives and pesticides on the surface of fruits, so it is safe to soak fruits in salt water and eat them.

Salt is used in fruit washing because salt can kill bacteria, but diluting pesticide residues or even removing pesticides is not necessarily effective

First of all, salt can indeed play an insecticidal role, especially for some mollusks with mucus on their own.

Salt is simply lethal to them. But salt is a bit of a paper tiger for pesticidesIt doesn't matter if it's concentrated salt water orLight salt water, can not remove the residual pesticide on the surface of the melon and fruit

The main component of salt is sodium chloride.

Sodium chloride is a very stable chemical and does not react with ordinary chemicals.

So, wantIt is not possible to use salt water to clean the surface of fruits and vegetables with pesticide residues。Although salt is added to the water, it is actually just "a basin of water + a little salt", which plays a role in cleaning only clean water, and salt does not play a role in removing pesticides.

Not only that, but some vegetables have cell membranes.

It is very fragile, if it encounters a high concentration of salt water, it is very likely that the cup of salt water will be destroyed, which will not only make the vegetables lose their original nutrients, but also make the residual pesticides take advantage of the void to penetrate into the fruits and vegetables, and be eaten more.

Brackish water does have an effect on the removal of pesticide residues, but there are still many things to pay attention to when soaking in brine. The effect of the soaking time is quite different. From the above data we can find thatIt is not that the longer you soak, the cleaner it will be removed, and it is best to soak for about 20 minutes.

This is because as the soaking time increases, the osmotic pressure.

The change will cause the pesticide in the brine to be sucked back into the vegetables, causing the residue to rise again. The removal effect of 1% brackish water is optimal, and the removal effect decreases as the concentration increases.

In fact, remove pesticide residues from fruits and vegetablesRunning water is the best choice。You can also try it inAdd a little to the waterEdible alkaliBecause most pesticides are acidic, with edible alkali and neutralization, pesticides are naturally cleaned.

Weakly alkalineRice waterIt is also a good choice, and it is very environmentally friendly in addition to cleaning fruits and vegetables.
