What are the hazards of pesticide residues in fruits and vegetables?
Fruits and vegetables are sweet and sour, rich in nutrients, and are loved by young and old, but most fruits and vegetables are sprayed with pesticides to kill insects. Therefore, most of the pesticides are left on the fruits and vegetables sold in the market. Toxins in pesticides are easy to cause after accumulation in the human body. Chronic poisoning and triggers a number of chronic diseases. Usually, we eat the fruits and vegetables and rinse them with water. This does not wash the pesticides attached to the fruits and vegetables.
1. After the pesticides remaining on the vegetables and fruits enter the bloodstream, they are scattered along the synapses and neuromuscular junctions, causing direct damage to the neurons in our body, causing the death of the central nervous system. Reduce the immunity of human organs, causing diseases such as cardiovascular and cerebrovascular diseases.
2, pesticides basically contain a lot of chemicals, these substances may cause cancer cells in the body, causing cancer.
3. The pesticide toxins remaining on fruits and vegetables are mainly absorbed by enzymes made by the liver for oxidative decomposition. The pesticide residue that lasts for a long time makes the liver break down the toxin all the time, leaving the liver overloaded, eventually causing diseases such as cirrhosis and hydronephrosis.
4, there are more folds on the stomach wall, pesticide toxins are easy to adhere to these folds, causing discomfort such as nausea and diarrhea.
5. The human body constantly accumulates pesticides in fruits and vegetables. It may transmit these toxins to children during pregnancy and breastfeeding, and may cause abnormal fetal growth or affect children’s healthy development.
How to wash off the pesticide residues on vegetables
Vegetables and fruits are an indispensable part of our lives. For different people, different vegetables are needed to supplement the nutrients needed by the body. But we all know that many vegetables will not be able to be free of pesticides. Normal growth, so we need to remove the residual pesticides when we are eating. Here is a look at how to remove residual pesticides from vegetables. How to wash off the pesticide residues on vegetables First, rinse with water Residues on vegetables are mostly acidic, so we can choose a slightly alkaline rice water, so that we can remove most of the pesticides well, and then we can soak it in water for about a quarter of an hour. We can continue to repeatedly smash, be careful not to rot the leaves, otherwise it will easily cause secondary pollution. Second, peel off the outer leaves Many vegetables in life have a protective outer leaf, and the amount of pesticide residues in these parts is the most, like onions, cabbage, kale, potatoes, etc., so we can directly remove the outer layer. This is also a good way to remove residual pesticides. How to wash off the pesticide residues on vegetables Third, hot water For some pesticides or vegetables that are not easy to handle, such as cowpeas, green beans, etc., we can wash the dirty things and rub them in boiling water. We can remove 90% of the pesticides. If you fry directly, it is easy to cause the pesticide to penetrate into the inside of the vegetables. Fourth, peeling cleaning Many vegetables in life are covered with skin. Like common cucumbers, melons, eggplants, etc., we just carry out simple peeling, which can remove the pesticides left on it, but we should pay attention to the best choice. Seasonal vegetables, otherwise the vegetables may contain different levels of hormones, and eating too much is not good for the body.
How to remove pesticides from vegetables and fruits
(1) Water soaking and washing method Mainly used for leafy vegetables, such as spinach, lettuce, and Chinese cabbage. Generally, rinse off the surface dirt with water, remove the visible stains, and then cover the fruit and vegetable parts with water for about 5 cm. The soaking in running water should be no less than 30 minutes. If necessary, add a cleaning agent such as a fruit and vegetable lotion to increase the dissolution of the pesticide. Soaking and soaking for 2 to 3 times can basically remove most of the residual pesticide components. (2) Alkaline water soaking cleaning method Most organophosphorus pesticides decompose rapidly in an alkaline environment. Generally, 5 to 10 grams of edible alkali is added to 500 ml of clear water to prepare alkaline water. The fruit and vegetables after preliminary washing are placed in alkaline water, and the amount of the vegetable is mixed with the alkali water. After soaking for 5 to 15 minutes, the fruits and vegetables are washed with water. Repeated washing 3 times or so is better. (3) Heating cooking method Commonly used in celery, cabbage, green pepper, beans and so on. Since the carbamate insecticide will accelerate decomposition as the temperature increases, the washed fruits and vegetables are usually taken out in boiling water for 2 to 5 minutes, and then immediately removed, and then washed with water for 1 to 2 times. Cook in a pot and cook into a dish. (4) Cleaning and peeling method For fruits and vegetables with skin, the appearance of residual pesticides can be peeled off with a sharpener and eaten with fleshy parts, which is both delicious and safe. (5) Storage and storage method Certain pesticides slowly decompose over time into substances that are harmless to the human body during storage. Therefore, when conditions permit, some fruits suitable for storage and storage should be purchased and stored for a period of time (10-15 days). It will be better to wash and peel before eating.
Pesticides are easy to remain, and what are the effects of pesticide residues on fruits and vegetables?
Pesticides, especially organophosphorus pesticides, carbamate pesticides, pyrethroid pesticides, etc., all have certain adhesion and permeability and are easy to remain on fruits and vegetables. After eating, toxins are easily accumulated in the body, resulting in health. Various hazards. Specifically, pesticide residues on fruits and vegetables have the following effects on the body.
Easy to cause obesity When the liver cannot decompose toxic substances, it will be wrapped with fat to form cellulite. If the toxin continues to accumulate, the cellulite will increase and become larger to a certain extent, resulting in a slower metabolism and increased the fat content. ** Body fat.
2. Lead to decreased body immunity Long-term consumption of fruits and vegetables with residual pesticides, pesticides will be distributed to the synapses and neuromuscular junctions after being absorbed by the blood, directly damage the neurons, causing the central nervous system to die, resulting in decreased immunity of various organs of the body. For example, we have frequent colds, dizziness, heart palpitations, night sweats, insomnia, and forgetfulness.
3. Cause fetal visceral hypoplasia or deformity The toxic substances in the residual pesticides will be absorbed by the fetus through the placenta in the pregnant women, resulting in the development of some internal organs of the fetus or malformation. Some children born with defects are poisoned by the uterus. One. Therefore, in the process of pregnancy, including postpartum breastfeeding, women, in particular, should pay attention to the safety and health of the diet.
4. Increase the burden on the liver Residual pesticides enter the body, relying mainly on the liver to produce enzymes to absorb these toxins for oxidative decomposition. If you eat fruits and vegetables with residual pesticides for a long time, you need the liver to work constantly to break down these toxins. Long-term overload work can cause liver damage such as cirrhosis and hydronephrosis.
5. Lead to gastrointestinal diseases Due to the large pleural folds in the digestive system of the gastrointestinal tract, it is easy to accumulate poisons, and pesticides remaining on fruits and vegetables are easily accumulated here, causing symptoms such as chronic diarrhea and nausea.
6. May cause cancer A variety of chemicals contained in pesticides can easily induce mutations in organisms, thereby increasing the possibility of cell mutations, causing cells to become deformed and inducing cancer. In addition, pesticide residues on fruits and vegetables can easily lead to a variety of hidden diseases, which cause irreversible damage to health. Therefore, in purchasing, cleaning and cooking, we must try to scientifically select and handle them. The “dining table” became clean and healthy.
Do not use fruit and vegetable detergent for washing fruits and vegetables
Recently, a variety of fresh and delicious fruits have been listed, and strawberries, cherries, melons, and plums all say that eating fruits is good for health. However, many people are always worried about pesticide residues. In addition, there have been reports recently that pesticides in strawberries cause cancer, which makes people more worried. Therefore, many people should carefully clean the fruit after they go home, and use detergent and detergent to think that it can better remove pesticide residues. Fruits without detergent cleaning are not allowed to eat. Is this true? Is it really necessary? Detergent removes pesticide residues without magical effect Many people think that washing fruits with fruit and vegetable washing machine can remove pesticide residues more effectively and is safer. The detergent is mainly composed of components such as a surfactant, an emulsifier, a fragrance, and a pigment. When the fruit and vegetable are washed with a detergent, the emulsifier component contained therein is capable of decomposing the oil, making the water-insoluble substance soluble, making it an emulsion soluble in water, and then contaminating it with a surfactant. The object is separated from the object to be cleaned and then removed by washing and flowing water. Some types of detergents also have ingredients that inhibit pathogenic microorganisms, which can effectively prevent bacterial proliferation and prevent the spread of disease. However, can detergents remove pesticide residues? In fact, it may not be. Scientists have done a lot of research on this. There are also many fruit and vegetable cleaning agents in the United States, and many of them say that using their own detergent to absorb water can better remove pesticide residues. Some said that it is 98% better than clear water, and how good it is 3 times, 4 times, 5 times, 10 times. The University of California has conducted research on five kinds of fruit and vegetable detergents commonly used in the market and used these five kinds of fruit and vegetable detergents to clean fruits and vegetables. It was found that fruit and vegetable detergents can clean some fruits and vegetables, but they can not be removed 100%. Moreover, compared with water washing, fruit and vegetable detergents have not achieved the high efficiency of their claimed fruits and vegetables. On the contrary, there is no significant difference in the removal of pesticide residues between fruit and vegetable detergents and water rinses. A department of the Connecticut State Government has also conducted a relatively large-scale study on cleaning and pesticide residues. They selected 28 batches of lettuce, strawberries and other fruits and vegetables to detect changes in the levels of several common pesticides before and after washing. They used tap water, washing spirits and four specialized “fruit and vegetable cleansers”. It was found that each method significantly reduced pesticide residues, but the effects of these specialized fruit and vegetable cleaners were not different from those of clear water. They also found that these pesticides are easily washed away and have little to do with their solubility, mainly due to mechanical movement during cleaning. Therefore, washing fruits with fruit and vegetable detergents is not better than water. When cleaning fruits and vegetables, rinse under running water for more than 30 seconds, with a wash. Detergents also have security risks Because the detergent will directly contact the skin during use, it will also be in contact with our tableware, fruits, and vegetables. Therefore, the use of raw materials must meet safety standards and will not cause harm to the human body. Once the raw materials and products are used. If there is a problem in the processing, it will bring some harmful substances, which may put a risk to health. If the detergent is in the normal process, problems occur in the procurement of raw materials and in the production process, it will cause harmful substances such as formaldehyde, lead, arsenic, etc. in the detergent to exceed the national standards, which may cause harm to human health. Studies have found that detergents may have other substances harmful to the human body, such as arsenic and heavy metals. An important way for detergents to cause harm to people’s health is that the cleaning is not thorough. It is easy to have some detergent residues. The harmful substances that may remain in the detergent will enter the body directly through the digestive tract during the diet. Health lays a safety hazard. Of course, regular detergents do not cause health problems. However, consumers need to understand that washing with detergent and washing with water does not make a significant difference in removing pesticide residues. Instead, it may cause secondary pollution. Eating it may also be detrimental to the human body. In fact, the US Department of Agriculture also recommends that consumers do not use detergents such as soaps, fruit and vegetable detergents when cleaning fruits and vegetables. Therefore, when cleaning fruits and vegetables, we do not need to use fruit and vegetable detergents, and it is best not to rely on detergents.
What is the importance of vegetable cleaning in life?
1, washing fruits and vegetables It can effectively remove pesticide residues, hormones and preservatives in fruits and vegetables, and the degradation rate is over 95%. 2, washing meat It can effectively eliminate various hormones, toxins, and additives in meat. 3, washing the grain It can effectively eliminate excessive chromium, pollutants and heavy metals in cereals. The removal rate is as high as 90% or more. 4, dishwashing disinfection Can wash off bacteria, stains, and detergents from the tableware. 5, killing eggs Destroy the outer wall of the remaining eggs on the surface of fruits and vegetables and destroy them. 6, efficient decontamination Effectively cleans the sediment, dust, and stains on the surface of fruits and vegetables. 7, long-lasting preservation After the fruits and vegetables are cleaned in the detoxification machine, they are actually anti-mildew and disinfected. The storage time in the refrigerator is longer and the preservation time is longer.
How long does the vegetable bubble make, the pesticide can be removed? Pesticide residues in vegetables are an important issue in food safety. Especially in summer, it is the peak period of vegetable consumption and the active period of pests. In order to catch up with business opportunities, producers either use super-concentration pesticides to kill insects or harvest pesticides in advance, resulting in a large number of pesticide residues in vegetables exceeding the standard. According to statistics, under normal circumstances, the pass rate of pesticide residues in summer vegetables is more than 20% lower than that in winter. In order to reduce the pesticides on vegetables, people have come up with a variety of methods: drying in the sun, blisters, washing with rice, etc., but are these methods really effective, how many pesticides can be removed? The College of Food Science at China Agricultural University recently conducted an experiment to help people find the best way to remove pesticides. Since the pesticide is mainly attached to the surface of fruits and vegetables during the spraying process, as long as the effective washing and processing methods are adopted, the residual amount of the pesticide can be reduced, and the edible safety of the vegetables can be ensured. Soaking and rinsing with water can reduce the number of pesticide residues, and the longer the bubble time, the less pesticide residue. Tests have shown that 15 to 60% of pesticide residues can be removed by soaking the vegetables with tap water for 10 to 60 minutes and then washing them a little. Soaking with a special vegetable and fruit detergent is more effective in reducing the adhesion of pesticides. Dilute the detergent in water at a ratio of 1:200 and soak the fruits and vegetables. Within 10 to 60 minutes, the pesticide residue can be reduced by 50%-80%; especially in the first 10 minutes of soaking, the pesticide residue is very obvious, which can be reached. About 50%. Then, wash it a little and rinse it off with water to remove the pesticide residue. High-temperature heating can also decompose pesticides, such as boiling water or oil. Experiments have shown that some heat-resistant vegetables, such as cauliflower, beans, green peppers, celery, etc., can be washed with boiling water for a few minutes, which can reduce the pesticide residue by about 30%, and then remove the vegetables by high-temperature cooking. % of pesticides. In addition, washing rice with rice and proper sun exposure can also play a role in reducing pesticides on vegetables. But the rice water is best used once or twice because the surface of the rice contains potassium, so the first or twice of the rice water will be weakly acidic, but then it will start to change to alkaline, and the pesticide is only in the acidic substance. Will lose some toxicity. Sunlight can cause some pesticides in vegetables to be decomposed and destroyed. According to the measurement, when the vegetables are exposed to sunlight for 5 minutes, the residual loss of organochlorine and organic mercury pesticides can reach about 60%. Vegetable peeling can of course also reduce pesticide residues, but it also causes loss of vitamins and minerals in the skin. Therefore, the best way to remove pesticides is to soak the fresh fruits and vegetables with detergent for 10-15 minutes, or soak them in tap water for 30-60 minutes, and rinse them with water. Which fruits and vegetables are less polluted? At the same time that the “Poisonous Garlic” incident has attracted people’s attention, people are also trying to find ways to distinguish the contaminated fruits and vegetables from the appearance. Professor Li Lite, a doctoral tutor at the College of Food Science, China Agricultural University, said that it is impossible to distinguish whether the pesticides are excessive in terms of the shape and color of the vegetables. To reduce the health hazards of contaminated fruits and vegetables, it is first necessary to understand which vegetables and fruits are easier. Being polluted. Professor Li said that in general, fruits and vegetables that are more prone to insects and insects are more difficult to control, and are often more serious pesticides. For example, apples, pears, plums, grapes, strawberries, watermelons, oranges, bananas and other pesticide residues in fruits are more serious, while shelled fruits such as litchi and longan are less polluted. The more polluted vegetables are leafy vegetables and fine vegetables such as Chinese cabbage, green vegetables, chicken feathers, leeks, spinach, rapeseed, etc., while rooting vegetables, melons, and fruits (such as potatoes, pumpkins, cucumbers, bitter gourds, tomatoes, and melons). Onions, etc.) are relatively less polluted by pesticides, and the nutrients of these vegetables are also higher. Professor Li believes that there is no scientific reason for the saying “buy vegetables and buy insects without pesticides.” Because it is difficult for a vegetable farmer to kill all the pests at the same time, it takes a long time for the pests to develop resistance. When the vegetable farmers spray the medicine, they will escape, and then “kill will come back.” Therefore, there is no pesticide residue left on the vegetables. Moreover, the vegetable skin has a layer of wax that acts to prevent pests and toxic substances. Once the vegetable epidermis is damaged, pathogenic microorganisms such as various bacteria will take advantage of it, which is not conducive to human health. As far as small tomatoes and large tomatoes are concerned, Professor Li humorously said that small tomatoes are produced by foreigners in order to pay attention to eating. If we do not pay attention to eating at home, it is best to choose large tomatoes. Because the same weight of small tomatoes is much larger than the surface area of large tomatoes, the area of pesticides to be sprayed is also large, and the small tomatoes of the same pulp weight, because of the proportion of their peel, much more than the large tomatoes, nutrition Not as big as a tomato. In addition, effective methods of cleaning fruits and vegetables can also reduce pesticide contamination. Professor He Jiguo from the College of Food Science, China Agricultural University believes that the cleaning methods of different vegetables and fruits are strictly different. For example, cleaning eggplant, green peppers, and fruits, etc., people are used to gently washing the surface with their hands. Although this can remove some pesticides, they also remove the natural wax on the surface. If they are soaked for a long time with water, It is easy to make residual pesticides infiltrate into the inside of vegetables or pulp. Therefore, fruits and vegetables such as eggplant, apple, grape, strawberry, etc. are best washed with running water, and then equipped with a detergent for cleaning pesticides. The leafy vegetables, because the leaf is not convenient to clean by hand, the wax on the surface is not removed, it plays a role of isolation, the pesticide is not easy to infiltrate, so the leaf vegetables can be directly soaked, which can be reduced The role of pesticide residues.
How long does the pesticide on the vegetables generally remain?
Pesticide residues in vegetables are an important issue in food safety. Especially in summer, it is the peak period of vegetable consumption and the active period of pests. In order to catch up with business opportunities, producers use a lot of pesticides. How long will the pesticides on vegetables generally remain? How long does the pesticide on the vegetables generally remain? The vegetables on the table are closely related to the common people. How many pesticide residues in vegetables have always been our concern? Chronic poisoning is usually difficult to be discovered by us. It is often quite serious once symptoms appear. Now, it is the season of fruit and vegetable production, and the high incidence of gastrointestinal infectious diseases. Medical experts hereby solemnly remind you that eating unclean food will not only cause the loss of food nutrition but also bring great harm to human health. First of all, it can lead to gastrointestinal diseases. Due to the rich blood vessels in the digestive system of the gastrointestinal tract, the stomach wall is more wrinkled, and it is easy to retain poison. This makes the residual pesticides easily accumulate in it, causing symptoms such as chronic diarrhea and nausea. In addition, the liver will increase the burden of residual pesticides into the body, and the liver will continue to work to decompose these toxins. Overloading for a long time will cause liver cirrhosis and hydronephrosis. Moreover, the body’s immunity declines and long-term consumption of vegetables with residual pesticides. After the pesticides are absorbed by the blood, the neurons are directly damaged, resulting in decreased immunity of certain organs of the body, frequent flu, dizziness, palpitations, night sweats, and forgetfulness. The most terrible hazard is carcinogenicity. Residual pesticides often contain harmful substances such as methamidophos, parathion, and chlorinated benzene, which can cause cancer in cells in various tissues of the body. How long does the pesticide on the vegetables generally remain? It cannot be generalized. Generally, it can be calculated according to the safety interval. You can buy a portable pesticide residue detector which can easily and accurately measure the pesticide content in vegetables. It is also possible to use a fruit and vegetable detoxification machine, which can degrade pesticide residues on the surface of fruits and vegetables.
Fruit and vegetable pesticide residues are the most effective! Baby eats more assured
Fruit and vegetable pesticides? How to wash the spectrum?
Parents are always worried that the fruits and vegetables that the baby eats will have pesticides, which will be poisonous and will not be given to the baby. First of all, what we need to be clear is that having pesticide residues does not mean harmful.
It is normal to have pesticides in fruits and vegetables. We don’t have to regard it as a beast, but we should treat it rationally. In the formal way to buy fruits and vegetables, pesticide residues should not exceed the limits of national standards, there is no health risk to the human body.
However, there must be mothers who are worried: Who knows if there is any excess of pesticide residues on the farm, and it is certainly better for the baby to eat less. Is there any good way to remove pesticides? Of course, there is.
Ordinary water bubbles and rushing are not very effective in removing pesticides. You need to add proper washing (when you think about washing clothes).
For some more rough and thick fruits and vegetables can also be brushed with a clean brush, then rinse with water, this will be more effective, while also removing the dirt on the surface of fruits and vegetables to prevent bacterial infection.
In addition, there are many ways to spread the village, such as water, saltwater, vinegar, hot water, alkaline water, etc. to remove pesticide residues. Once CCTV did an experiment –
The vegetables are soaked in water, saltwater, vinegar water, boiling water, and alkaline water for the same time, and taken out to test the pesticide residue.
Using a quick test card, the darker the blue in the circle on the left, the less pesticide residue.
It was found that the effect of removing pesticide residues is:
Alkaline water>open water>salt vinegar water>salt water
The teammates of the Mommy team have also tried this experiment. It is indeed better to use the edible alkali (soda) to the pesticide residue. Because the pesticides used in fruits and vegetables are mainly organophosphorus pesticides, they decompose rapidly in an alkaline environment.
In addition, the baking sodas that are very familiar to the baking mothers are also alkaline, and the effect of pesticides is not bad.
Hot watering with boiled water is also an effective way to get rid of pesticides, but the leaves of the vegetables are hot and boiled. However, some hot-resistant dishes, such as beans, cauliflower, dried bamboo shoots, etc., can be hot water, then stir-fry will reduce a large number of pesticides.
● In addition, we do not recommend cleaning the fruits and vegetables with detergent. The detergent itself is secondary pollution, and the quality of the cleaning agent cannot be guaranteed. If it is not cleaned, it is not good for eating.
● Really worried about pesticide residues, can also peel the fruits and vegetables that can be peeled; easy to preserve fruits and vegetables, can also reduce pesticide residues through storage for a certain period of time; even further degrading pesticide residues through sun exposure; fruits and vegetables There are relatively many pesticide residues in the roots and pedicles. It is recommended to cut the roots one more time and remove the pedicles.
Does rice have to be washed repeatedly?
Before cooking, the rice should be washed several times. It is estimated that there are quite a lot of mothers tangled. The Buddha is Taotao, or is it washed to the clear water, not so white and turbid?
Rice has a defect, that is, the problem of heavy metal enrichment, which is really normal, related to heavy metal pollution in soil and water. However, in accordance with national standards, the heavy metal content will not exceed the standard, and the daily consumption will not cause any harm to the human body.
Mothers who are really concerned about heavy metals can soak rice for a while, and some heavy metals will “bubble” out of rice.
However, in the process of rice rinsing, it is not recommended to use the flowing water to wash the rice over and over again. Some nutrients such as vitamin B, protein and minerals are easily lost.
White rice is like this. Those colorful grains are more noticeable. They have a big advantage in that they contain more vitamins, anthocyanins and the like, and they are over-washed, but they will cause a lot of nutrient loss.
In fact, the best way is to choose high-quality rice with small pollution in the planting area, and do not eat rice exclusively, and combine with other miscellaneous grains, noodles and the like, and the staple foods should be diversified.
Then Naomi can be a part of the Buddha, remove some impurities and particles visible to the naked eye, do not use force, scouring the water one or two times enough ~ even some high-quality fresh rice (free of rice washing), do not need to clean, directly Eat rice to eat.
Clean raw meat carefully cross-contamination
I don’t know how many mothers who are in the room will wash the raw meat again (there should be a lot of lifting hands in the brain), but it is not recommended to clean the raw poultry before cooking. Because of the cleaning process, the juice with bacteria is easy to splash on the surface of other kitchen utensils, tableware, chopping boards, countertops, dish towels. If you don’t pay attention to cleaning, it is easy to cross-contamination with other foods (especially some ready-to-eat foods).
Therefore, fresh meat can be cooked directly, cooked and cooked, and high temperatures will naturally kill bacteria.
Do some people still think that it is possible not to clean the meat? I can’t do this in my life. If you really want to clean, it is recommended to put the meat in a container filled with cold water and wash it. In order to avoid cross-contamination, pay attention to these points:
1. When washing meat, put fewer kitchen utensils, food, etc. around;
2. When washing, don’t be too anxious, splashing everywhere, don’t be too anxious when pouring “sewage” into the sink.
3. If there is any splash around, it is best to clean it as soon as possible.
4. Always wash your hands, wash your hands, and wash your hands!
Do you want to clean the eggs?
The eggshell is porous, and a protective film is naturally present on the surface, which helps to block the penetration of bacteria into the eggshell and protect the inside.
In the United States, there is a one-step cleaning process in commercial egg processing. During the cleaning process, the protective layer is removed, so the protective film is replaced by a coating of edible mineral oil. Therefore, the eggs sold in the United States are very clean. The authoritative institutions in the United States recommend that the eggs not be cleaned, so as not to damage the protective film, but the bacteria will be emptied.
But the domestic situation is not the same, the eggs bought are not necessarily washed. If you see dirt or feces on the surface of the egg, you can put it in a plastic bag or box and do not mix it with other foods. Rinse the dirt off the surface before eating.
Eggs that need to be preserved should not be washed with water before storage, but “dry cleaning”. You can use a clean dry sponge to gently wipe off the dirt. Do not wipe the dirt without dirt, so as not to damage the protective layer.
If you have obsessive-compulsive disorder to wash with water, don’t use cold water. It is easy to shrink the inside of the egg to form a vacuum. Instead, the bacteria on the outer shell are “pressed” into the inside of the egg. Wash with warm water of about 40 degrees, wipe it dry, and put it in the refrigerator for storage.
What are the hazards to the body when eating vegetables with residual pesticides?
1, leading to decreased body immunity: long-term consumption of vegetables with residual pesticides, pesticides absorbed by the blood, can be distributed to the synapse and neuromuscular junctions, directly damage the neurons, causing central nervous system death, resulting in immunity of various organs of the body The power is falling. For example, frequent colds, dizziness, palpitations, night sweats, insomnia, forgetfulness, etc.
2, may cause cancer: chemical substances often contained in residual pesticides can cause cancer in cells of various tissues.
3, increase the burden of the liver: residual pesticides into the body, mainly rely on the liver to produce enzymes to absorb these toxins, oxidative decomposition. If you eat fruits and vegetables with residual pesticides for a long time, the liver will work constantly to break down these toxins. Long-term overload work can cause some dry liver lesions such as cirrhosis and hydronephrosis.
4, leading to gastrointestinal diseases: due to the gastrointestinal digestive system, the stomach wall folds more, easy to contain poison. Such residual pesticides are easily accumulated therein, causing symptoms such as chronic diarrhea and nausea.
Method for removing pesticide residues on vegetables
1, peeling method
Although organic phosphorus, organic mercury, and pyrethroid pesticides have low solubility in water, they are easily soluble in organic solvents or waxy liquids, while vegetables have many waxy surfaces and are easy to absorb pesticides. Therefore, vegetables that can be peeled, such as cucumber, loofah, pumpkin, etc., should be peeled and then eaten.
2, the alkaline water immersion method
Organophosphorus pesticides decompose rapidly in an alkaline environment, so this method is an effective measure to remove pesticide pollution and can be used for various vegetables and fruits. The method is to first put a small baking soda in the water, stir well and then add the vegetables. After soaking for 15 minutes, pour the alkaline water, then rinse with water.
3, heating method
As the temperature increases, the decomposition of carbamate insecticides is accelerated. Therefore, some vegetables and fruits that are difficult to handle by other methods can be removed by heating, such as amaranth (water spinach), green vegetables, celery, cauliflower, beans. Wait. The method is to first clean the surface dirt with water and put it into boiling water for 2 to 3 minutes to remove it. According to the test, more than 80% of the residual pesticide can be removed.
4, the use of oxygen detoxification
Oxygen is a relatively stable molecular structure with much less oxidizing power than ozone. Ozone (oxygen) is composed of an oxygen molecule carrying an oxygen atom; the oxygen atom is extremely active and oxidizing. At present, the new environmentally-friendly small household appliances “oxygen detoxification machine” or “multi-functional oxygen machine” appears on the market is actually using the strong oxidizing ability of active oxygen to decompose residual pesticides on the surface of fruits and vegetables.
Since the oxidative decomposition ability of ozone in water is stronger and faster than in air, cleaning vegetables and fruits with active oxygen water has a good effect of removing pesticide residues.
