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.
