Apple waxing is not reliable

Recently, a video of "Apple Waxing" has spread in the circle of friends
.
In the video, an employee wearing gloves applied a reddish-brown liquid evenly on the apple, and the color of the apple was immediately "brilliant
.
" Watching this video, many netizens have complained about whether it is possible to make people eat apples happily? In addition, some netizens claim that eating waxing is easy to cause cancer
.
Experts say that the claim that apple waxing causes cancer is unreliable
.
So, does Apple wax artificially? How to distinguish and eat it?Artificial fruit waxis harmlessto the human body.
It is understood that there are two main types of wax on apple peels, one is the fruit wax naturally produced by the apple itself
.
In fact, during the growth of an apple, its epidermis itself secretes a layer of fruit wax
.
This kind of fruit wax is an ester component, which can prevent external microorganisms and pesticides from invading the pulp.
It is a protective measure for the apple itself against the external environment.
This substance is harmless to the human body
.
In addition, in order to prevent water loss and insect damage during the production and transportation of apples, it looks fresher and brighter, which makes the appearance of apples better, and some businesses choose to wax them manually
.
In fact, Apple waxing is nothing new, nor is it illegal
.
Ruan Guangfeng, a Master of Nutrition and Food Research, said that in China, waxing and fresh-keeping treatment is allowed on the surface of fruits.
According to the "Sanitary Standards for the Use of Food Additives", morpholine fatty acid salts (also known as fruit wax), carnauba wax, etc.
Used as a coating agent on the surface of fresh fruits, which is commonly known as waxing
.
　　The fruit wax produced by the apple itself is a kind of ester component, which is harmless to the human body, so you don't need to worry too much
.
So, what about artificial wax? Ruan Guangfeng said that apples can be waxed, but the waxing must comply with national regulations.
Only "food-grade wax" can be used and meet national standards.

.
China's standards stipulate that commonly used edible waxes, including morpholine fatty acid salt (also known as fruit wax), carnauba wax, etc.
, are all food additives, and reasonable use will not be harmful to the human body
.
　　The composition of industrial wax is complicated.
　　pay attention to cleaning.
　　At present, because of cost considerations, waxing is not popular in ordinary apples on the market
.
"Waxing apples with artificial fruit wax requires a special waxing machine.
The apples are cleaned first, dried and then waxed
.
The cost of labor, materials, and machinery is not low, so generally only high-quality apples are waxed
.
"An industry insider said
.
　　However, some unscrupulous vendors use industrial wax in order to save costs, shoddy, and increase Apple's "worth"
.
For example, in order to make ordinary apples look better, some cheap industrial paraffins are used for waxing.
These industrial paraffins contain toxic components such as polycyclic aromatic hydrocarbons, which can cause harm to the human body if consumed for a long time
.
In addition, it is difficult to judge whether the wax on the surface of an apple is edible wax or industrial wax based solely on human vision or smell
.
Some people in the industry suggest that if you are in doubt about whether an apple is waxed, you can wipe the peel with a paper towel when selecting it.
It can easily wipe off a faint red layer, which may be industrial wax
.
In addition, it is recommended not to blindly chase brightly colored "high-end" apples
.
　　Experts said that the composition of industrial wax is relatively complex and unknown, and may contain heavy metals such as lead and mercury.
Eating it will bring risks to human health
.
But this risk is currently potential and unknown.
As for the carcinogenicity of waxed apples, it is completely unfounded, exaggerating the risk
.
In addition, we wash and even peel the apples when we eat them
.
It is not eaten in large quantities every day, so consumers don't need to worry too much
.
　　Experts suggest that if you are worried about health problems, you can peel and eat.
If you don’t want to peel, you can choose a reasonable cleaning method.

.
It is reported that there are generally two cleaning methods.
One is to wash with hot water, which can easily clean the preservative of the apple skin, but pay attention to the water temperature and do not overheat the apple's taste
.
The other is to wash with salt.
After the apple is soaked in water, put a little salt on the epidermis, and then gently rub the apple back and forth with both hands, and then rinse with water
.
The principle of this cleaning is to use the small particle state of salt to enhance friction, and the salt itself also has a disinfecting effect
.
Of course, you can also use a special fruit detergent for cleaning
