What to do if there is paraffin on the skin of apples

　　Dangers of eating apples: Expanding hormones promote growth, red pigments increase color, and preservatives keep them fresh. Excessive use of elastin, erythrophorin, and preservatives can damage the liver. Retail fruit vendors will also coat apples with industrial paraffin to retain moisture and make the fruit bright and attractive.

　　So what should I do if there is wax on the skin of the apple?

　　From a nutritional point of view, you should choose to eat apples with the skin on because the skin contains more antioxidants than the pulp. In fact, the wax on apple skin is mainly divided into the following three types:

　　The first is the natural fruit wax on the surface of the apple itself. This 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. It 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. 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.

　　It’s best to chew apples carefully for fifteen minutes

　　Apples have high nutritional value and are rich in vitamins and acids.

　　According to experts, you should not eat apples too quickly. If you chew it in your mouth for a longer time, more saliva and gastric juice can be secreted, which will help promote the body's absorption and digestion of apple nutrients.

　　From a nutritional point of view, we do not advocate the 'gorgeous' eating method. For people with weak gastrointestinal tract, they need to pay special attention to the speed of eating apples. Eating too fast can easily lead to indigestion and discomfort.

　　Everyone may have had this experience: after eating an apple for a long time, the bitten surface will turn yellow, and the moisture content of that part of the pulp will also decrease, becoming softer and less crisp. Experts explained that this is actually the result of oxidation of apples. Although the "appearance" is ugly and the taste is not particularly good, its nutrients are not lost, and generally speaking, eating it will not cause any harm.
