Should I cut the joint of the apple? Why? Should I wash it with salt?

Yes, because it is difficult to wash and it is easy to have pesticide dust.

You'd better peel the apple before eating. Although some people say that the apple skin is rich in nutrition, it is true, but there are more pesticide residues and wax on the apple skin to keep it fresh. more harm than good

I know the detailed explanation of the daily newspaper:

I don't know when, "eating with skin is enough nutrition" has become the guiding principle of eating fruit. Often under the threat of his wife, he chewed a green apple and made the taste buds suffer. At the same time, fruit knives and peelers at home are in danger of being cut off. At this time, I can't help thinking, can the sacrificed taste be exchanged for enough nutrition?

Except for ...

Eating kumquat and other fruits, I'm afraid most of the peels won't make our tongues comfortable. For fruits, this layer of cells should prevent water loss on the one hand, and guard against the invasion of animals and microorganisms on the other. place

Therefore, the cells here should be closely interdependent, and the feeling of "chewing wax with the same taste" will naturally not be much better. Moreover, as a defense system, storage is indispensable.

Prepare some chemical weapons against animals that steal their mouths at inappropriate times. Although these sour chemical weapons will be largely removed when the fruit is ripe, their content is still higher than that of Binet.Alfred's pulp.

After reading a lot of literature, I can't know where the word "eating peel" comes from. In fact, the "peel" and "pulp" on fruits such as apples and pears belong to the peel structure in plant anatomy. More interesting

However, discarded peels like oranges are structurally equivalent to the "skin" and "pulp" of apples. The so-called peel is nutritious, which is more like a jingle in the mouth of a fortune teller.

Of course, if the nutrients in the peel are not too high, after all, these cells should be arranged more closely and have less water. But don't forget, even if the "content" is several times higher than the pulp, considering the weight ratio of the two, the contribution of the peel to the total nutrition is very small.

The peel has only one thing to show off, that is, the anthocyanins and other pigments it contains are usually lacking in the pulp. However, the role of these pigments is mostly to attract animals to feed. As for, in order to make the emerging health care substances play a role, I'm afraid I have to swallow the peeled skin.

Note that even under the normal use of pesticides, the pesticide residue in apple peel is 20% higher than that in pulp. Although these normally carried residual apples will not cause toxic reactions, who can guarantee that there will be?

Some fruit farmers who are forced to produce beautiful big apples will not use more pesticides to welcome big apples. Those big apples planted organically can be chewed with confidence (provided they are really planted organically), but even if they are planted organically,

The nutrition in the peel will not increase, and it is not a wise choice to exchange a lot of money for the legendary nutrition and inferior taste.

Of course, the peel is not useless, and the pigment inside can really decorate our dining table. The attractive color of dry red wine is attributed to the pigment in grape skin. Researchers are trying to extract natural pigments from different peels (orange in apricot peel, purple in mangosteen, etc.). ) Add colorful healthy pigments to our dining table.
