Why should the fruit surface be coated with wax, and how to remove these waxes?

The wax coating on the surface of fruit must have the functions of preventing oxidation, water evaporation and anticorrosion. We didn't have these on the skin of the fruit we ate at that time, so the shelf life of the fruit was short. But now, with the waxing of the fruit skin, this fruit can be preserved for a long time. I bought a bag of apples and put them in my bedroom. The apples haven't changed for two months. They are especially shiny when they touch the surface, so they must be waxed. I didn't think there was anything wrong with waxing before, it was just a fresh-keeping method, but it is said that fruits don't rot for a long time and eat toxic things. When I go to buy fruit, I usually go to several stores and choose a fruit that I want to eat without waxing. After that, I stopped buying waxed fruit.

Our life is rather rough, and we pay more attention to washing fruits. It used to be washed, and even the skin was chewed directly. There is wax now. I felt that the wax could not be washed off, so I peeled it off. This is a discount, and I don't like it. You can only eat a fruit if you grind your teeth. You don't like eating fruit just for nutritional needs. Now you are more tired of eating fruit. Now, according to the situation of fruit, you must peel it when you really eat it. Whether there is wax on it or not, the fruit is still peeled after pesticide treatment.

I used to watch TV to sell things, but that was limited to removing pesticides. Now the technology should be more developed. It is ok to buy such a musical instrument, once and for all.

Now there are many detergents on Taobao, so you can buy one to remove wax, but although this detergent can remove wax, it is also a headache to bring other things, so it is finally recommended to remove dead skin.
