From a nutritional point of view, you should choose to eat apples with their skins on, because compared to the pulp, apple skins contain more antioxidants. In fact, the wax on the apple skin is mainly divided into the following three types:
First, the natural fruit wax on the surface of the apple itself, which is a lipid component and a plant protective layer generated on the surface of the apple. It can effectively prevent external microorganisms, pesticides, etc. from invading the pulp and play a protective role, which does not need to be removed.
The second type is edible wax artificially added to some imported apples. This "artificial fruit wax" is actually a chitosan substance, which is mostly extracted from crustaceans such as crabs and shells. Come. This substance itself is not harmful to the body. Its function is mainly used to preserve freshness and prevent apples from rotting and deteriorating during long-distance transportation and long-term storage. It is also very simple to remove this layer of wax, just rinse it with hot water and it can be removed.
The third type is industrial wax, which contains mercury and lead that may penetrate into the pulp through the peel and cause harm to the human body. The identification method is: wipe the surface of the peel with your hands or a napkin. If a layer of light red substance can be wiped off, it may be industrial wax.
You cannot complete your health by eating more fresh fruits, so men and women usually buy some fruits. However, like apples and oranges, we often encounter "wax" on the skin. Some people think this is normal, and some people think it is an unscrupulous business. How about it? can you eat it?
Usually, there are three types of wax on the fruit skin:
Natural existence
The surface itself has a layer of juice, which is a lipid component. A plant protective layer created on the surface of the apple. It can effectively prevent external microorganisms, pesticides, etc., with a protective effect.
This natural wax has no negative effects on the body.
Artificial wax
Some merchants will make a layer of wax on fruits and other fruits for preservation or more, which is a chitosan substance, which is obtained from crustaceans Extracted from animals such as crabs and shells.
Although it is man-made, it is not harmful to the body because it is extracted from natural substances.
Industrial wax
If you want to see the fruit, you won't be able to use edible wax, you will be using industrial wax to wax, it contains mercury, lead which can flake off Entering the body can cause harm to the human body.
To identify wax and industrial wax, it is very simple. When picking fruits, wipe the surface with your hands or a napkin. If you wipe the fruit with a light red color, it may be industrial wax and it is recommended not to buy it.
Of course, everyone is less worried because not all apples are waxed. The storage time and transportation distance of fruits and vegetables in this season are not long, so the necessity of waxing is not high.
If you don't want to eat well, rinse the fruit directly on the surface with hot water.
Salt can also be used. After soaking the apples in cold water, put a little salt in the set, then hold the apple gently, the surface can be quickly cleaned, and then clean with water, you can eat it.
