As the saying goes, "An apple a day, the doctor is away from me" is enough to show people's love for apples. At the moment, it is the time when local apples are mass-marketed. Many people are moving home from the whole bag. However, when it was time to eat, some people were guilty: eating peeled for fear of losing nutrition, even eating skin and worrying that apples were waxed and eaten harmfully. The expert gave the answer: to identify whether the wax on the apple can actually eat.
Peel is more nutritious than pulp
There are many varieties of apples, including not only crispy instant noodles, Fuji, Guoguang apples, and soft banana apples, but also domestically produced local apples and imported snakefruit that has been shipped to Beijing by sea. So many varieties of apples, in the end which is the most nutritious? China Agricultural University Food and Nutrition Department of Nutrition and Food Safety Dr. Fan Zhihong told reporters that Apple's varieties are indeed many, but to be similar in terms of nutrition, should still be based on personal taste and preferences apple.
Whether apples should be peeled or eaten by skin is long debated. Fan Zhihong said that simply from the perspective of nutrition, it is definitely the choice to eat with the skin. This is because compared to flesh, apple skin is indeed rich in nutrients, has stronger antioxidant properties, and can prevent chronic diseases such as hypertension. .
Three types of wax on the peel
When many people do not peel their skin to eat apples, they often feel oily and waxy on the surface of the apple, and are worried that this layer of wax will harm the body. Fan Zhihong said that the wax on the peel has three main conditions: the surface of the apple itself. With a layer of fruit wax, which is a lipid component, is a plant protection layer generated on the surface of apples, it can effectively prevent external microorganisms, pesticides and other invasion of pulp, play a protective role; some high-grade apples with wax , It is artificially added to the consumption of wax, this "artificial fruit wax" is actually a chitosan material, and more from crabs, shells and other crustaceans extracted from the material itself is not harmful to the body, its The role is mainly used to keep fresh, prevent apple from rotting and deteriorating during long-distance transportation and long-term storage. To remove this layer is very simple to use wax, rinse directly with hot water to remove the layer of artificial edible wax on the surface of the apple.
The third kind of wax that people should worry about is illegal hawkers using industrial waxes to wax fruits. The mercury and lead contained in these waxes may permeate through the skin and cause harm to the human body. Therefore, in the selection of waxed fruit, you can use hand or napkin to wipe the surface of the fruit, if you can wipe a light layer of red, do not buy, this is likely to be industrial wax.
Can ripen other fruits
When picking apples, try to select the best bagging treatment (wrapped in bags during fruit growth, which can effectively prevent pests and pesticide contamination). The apple skin is clean and uniform, and it is less affected by polluted gas and pesticide spraying. Autumn is the season when apples mature. Fresh apples are sold at the time without preservatives and eating the skin is safer. Moreover, fresh apples have natural fruit wax on their surface, and they can see a layer of white frost. If it is a particularly beautiful apple, especially an off-season apple, it is best to peel it before eating. Apples can be kept fresh for 7-10 days in a cool place. If you put them in a plastic bag and put them in the refrigerator, they can be stored for longer, but the nutrients will be lost.
Apple also has the role of ripening fruit. If the unripe kiwifruit is placed in a plastic bag with apples, the ethylene released by the apple has the effect of ripening other fruits and can soften the kiwifruit or pears. However, if you put apples together with other mature fruits and vegetables, it will accelerate its decay and should be avoided.
