There are three types of wax on fruits: natural wax, artificial fruit wax, and industrial wax. So which wax is harmful to the human body? Let’s understand them one by one.
The surface of the capsule has a layer of fruit wax, which is a lipid component and a plant protective layer formed on the surface of the apple. It can effectively prevent outside microorganisms and pesticides from invading the pulp and play a protective role.
This natural wax can be used without any negative effects on the body.
Artificial fruit wax
In order to preserve freshness or make the fruit look better, some businesses put a layer of edible wax on apples and other fruits. This is a chitosan substance that is mostly extracted from crustaceans such as crabs and shells.
Although radon is artificially applied, it is not harmful to the body because it is extracted from natural materials.
Unscrupulous merchants want fruits to look better, but are not willing to buy edible wax, they will use industrial wax to wax the fruit, the mercury and lead contained in it may penetrate into the pulp through the peel, causing harm to the human body.
So, of the above three waxes, only industrial waxes are harmful to the human body, how can we distinguish industrial waxes? You can wipe the fruit surface with your hand or a napkin when you pick the fruit. If you wipe a layer of red, this is most likely an industrial wax.
Therefore, if the fruit you eat has industrial wax, it is best to peel it. If it is determined to be edible wax, you can not peel it, but you must clean it to prevent pesticide residues from affecting your health.
