What is the layer of white scraped off the outside of the apple

During the growth process of apples, the skin will secrete a layer of natural fruit wax, and a thin layer of white substance scraped off the skin of fresh apples is natural fruit wax. When you eat apples, you will find that the surface of apples is oily to the touch, and when you scrape something, there will be a layer of hoarfrost, and this hoarfrost is fruit wax. Some of the waxes are natural, and most of them are generally made of gums.

Beeswax, shellac.

and other substances are made of liquid wax made from organic solvents, and then applied to the surface of apples. 2 What does the wax on the surface of apples do?

Protect the apples. In addition to the artificial fruit wax, the apple itself will also secrete a natural fruit wax, which adheres to the surface of the apple to provide a protective layer for the apple, which can effectively prevent the invasion of external bacteria and microorganisms, so as to play a certain protective role in the apple.

Preservation. Apples need to go through a long process from picking to transportation, and the wax composition can play a role in preserving the freshness of apples, which can reduce the loss of water from apples, so as to prevent apples from rotting and deteriorating during transportation. 3 Can you eat the wax on the surface of apples?

It depends.

If it is the natural fruit wax on the surface of the apple itself, it can be eaten directly, and it will not cause any adverse effects on health when eaten. However, if it is artificially added wax, it is recommended that it should be cleaned before eating, because some black-hearted merchants will coat the surface of apples with industrial wax in order to make money, and these industrial waxes will contain heavy metals such as mercury and lead that are harmful to the human body.

It can be harmful to human health after consumption, so it is generally not recommended to consume it directly.

The white powder scraped from the surface of apples is natural fruit wax.

Apples themselves will produce a natural fruit wax, most of the apples sold on the market will produce natural fruit wax, the white powder that we can scrape out is a natural lipid component, which is commonly known as natural fruit wax, which does not have any harm to the human body.

Waxing generally appears on some high-end or imported fruits that need to be transported over long distances, and the main purpose of waxing the fruit is to keep the skin from dehydration for a long time. The domestic apples sold in the market are basically not waxed, because after the apple is fully ripe, the skin itself produces fruit wax, which is a membrane produced by the apple for self-protection. The thicker the skin, the more wax there is, which can be scraped off with a knife.

It turns out that the production of high-quality apples requires waxing, and most of the apples are bagged when they grow, so there is no need for waxing.

The surface of the apple itself has a layer of fruit wax, which is a lipid component, which is a plant protective layer generated on the surface of the apple, which can effectively prevent external microorganisms and pesticides from invading the pulp and play a protective role.

Some high-grade apples with wax on it, is artificially added to the edible wax, this "artificial wax" is actually a kind of chitosan substance, mostly extracted from crabs, shells and other crustaceans, this substance itself is not harmless to the body, its role is mainly used to keep fresh, to prevent apples from rotting and deteriorating in long-distance transportation and long-term storage.

In fact, the third type of wax is to be worried - unscrupulous vendors use industrial wax to wax fruits, which contains mercury and lead that may penetrate into the pulp through the peel and bring harm to the human body.

The white powder scraped out of the outside of the apple is the wax on the peel, and the wax on the peel mainly includes:

1. A layer of fruit wax on the surface of the apple itself, which is a lipid component, is a plant protective layer generated on the surface of the apple, which can effectively prevent external microorganisms and pesticides from invading the pulp and play a protective role;

2. The wax on the high eggplant oak apple is an edible wax added artificially, this "only pants artificial fruit wax" is a chitosan substance, which is extracted from crabs, shells and other crustaceans, this substance itself is not harmless to the body, and its function is mainly used to keep it fresh, preventing apples from rotting and deteriorating in long-distance transportation and long-term storage;

3. The mercury and lead contained in the industrial wax used by illegal hawkers may penetrate into the pulp through the peel and bring harm to the human body.

It is best not to eat anything white on the surface of the apple, and to blanch, scrub or peel it with hot water before eating.

There is a layer of white on the surface of the apple that is wax, and there are three types of wax on the peel:

1. The fruit wax on the surface of the fruit itself;

2. Some edible wax added to some high-grade fruits and artificially added this wax is harmless to the body;

3. Unscrupulous hawkers use industrial wax to wax fruits, which contain mercury and lead that may penetrate into the pulp through the peel, and fruits waxed with inferior industrial wax are harmful to health.

It is understood that China's "Hygienic Standards for the Use of Food Additives" allows waxing on the surface of fresh fruits, but the specified additives must be used and added in an appropriate amount. The commonly used edible wax is a food additive, and reasonable use will not be harmful to the human body.

If you eat too much, it may cause excessive burden on the body's detoxification and decomposition organs such as the liver, and affect your health. When buying fruit, wipe the surface of the fruit with a paper towel, if you can wipe off a faint layer of red, it may be industrial wax, and it is best not to buy this fruit.

The white substance scraped off the skin of the apple is fruit wax.

Fruit wax is a liquid wax made from substances such as gum, beeswax, and shellac with organic solvents.

It is understood that the state allows the use of fruit wax to keep fruits fresh in the relevant food additive specifications. The effect of fruit wax application is mainly to prevent the evaporation of fruit water and beautify the appearance, and also to prevent the invasion of germs.

Waxing fruit is an internationally permissible method of preservation, with well-established processes and regulations. China's "Hygienic Standards for the Use of Food Additives" also allows waxing on the surface of fresh fruits, but the specified additives must be used and added in an appropriate amount. In addition to apples, citrus, pears, etc. may also be waxed.

In fact, it is not difficult to distinguish between waxed fruits. If you compare two apples, you will find that the skin is extraordinarily smooth and the color is particularly bright, that is, it has been waxed; The skin is rougher to the touch, and it is not waxed.

It could be fruit powder, it could be dust, it could be wax. Take a visual look at it. Either way, wash or peel before eating.

The white ash that merchants use to make apples look good are all unscrupulous merchants.

White wax、This must be washed。

It may be a "wax bag", but all apples can be scraped off, even if you pick wild fruits from the mountains, the white powder is a substance on the surface of the fruit, which comes from the fruit itself and not from the later man-made .

Apples themselves will produce a natural fruit wax, most of the apples sold on the market now will produce natural fruit wax, the white powder that everyone can scrape out, is a natural lipid component, that is, commonly known as natural fruit wax, which does not have any harm to the human body. "Waxing is generally found on some high-end or imported fruits that need to be transported over long distances. Su Xiaodong said that the main purpose of waxing the fruit is to keep the skin from dehydration for a long time.

At present, there are basically no waxed apples sold in the market. Because when the apple is fully ripe, the skin itself produces fruit wax, which is a membrane produced by the apple for self-protection. The thicker the skin, the more wax there is, which can be scraped off with a knife, "The original production of high-quality apples requires waxing, but now most of the apples are bagged when they grow, so there is no need for waxing." ”

My mother-in-law's family grows apples.

The situation you said may be set of wax bags, but all apples can be scraped off, even if you pick wild fruits (apples) from the mountains, I did this experiment, white powder is a substance on the surface of the fruit, from the fruit itself, not later artificial (not professional, can only say so much, what is certain is that wax is available in the apple industry).

It is a fruit wax that gives the apple a fresh, shiny look.

There are two possibilities, one is fruit powder, which is harmless to people; The second is artificially applied preservatives, which are harmful to people.

Wax, because it is a protective film, makes apples look fresher.
