Can grape skins be eaten? Grape skins are edible. Although they have an astringent taste, they are rich in nutrients and are beneficial to the human body after eating. Since there may be pesticide residues on grape skins, grapes must be washed before eating to avoid affecting health.
Can grape skins be eaten?
Grape skins can be eaten. When people eat grapes, except for seedless white grapes, they often eat them with their skins. When eating other grapes, they spit out the skins because the grape skins have an astringent taste. But from a nutritional point of view, don’t spit out the skin when eating grapes.
Modern medicine has discovered that grape skins and grape seeds contain an antioxidant called resveratrol, which has preventive and therapeutic effects on skin cancer and cardiovascular and cerebrovascular diseases. In addition, the natural pigments in grape skins have good effects on lowering blood sugar and anti-cancer. Dark-colored (purple, red) grapes have higher natural pigment content than light-colored (green, white) grape skins. Peeled grapes have higher A lot of functions will be lost, so there is a scientific reason for "eating grapes without spitting out the grape skins".
In addition, grapes and their products also have anti-viral active ingredients. Studies have shown that fresh grapes and grape juice have stronger anti-viral abilities than wine, and among wines, red wine has the strongest anti-viral activity. Red wine contains flavonoids, especially quercetin, which can reduce the stickiness of platelets. Hard wine and beer do not have such benefits. Therefore, drinking red wine in moderation can protect the heart and reduce the harm of cardiovascular disease. .

Efficacy and role of grape skin
1. Grape skin is rich in a polyhydroxyphenolic compound-resveratrol, which has the functions of lowering blood lipids, anti-thrombosis, and preventing arteriosclerosis. Sclerosis, immune enhancement and other functions.
2. Tannin, another important substance in grape skin, has the effects of anti-allergy, delaying aging, enhancing immunity and preventing cardiovascular and cerebrovascular diseases.
3. The anthocyanins contained in grape skins have strong antioxidant, anti-mutation, alleviation of liver dysfunction, and cardiovascular protection functions.
4. Grape skin also has anti-cancer effects. Researchers from Illinois Pharmaceutical University found that this substance exists to varying degrees in more than 70 kinds of plants including peanuts and grapes. , especially in grape skins and red wines
5. The natural pigments in grape skins have good effects on lowering blood sugar and anti-cancer, and dark grape skins have higher natural pigment content
How to eat grape skins
Since most of the grapes currently on the market have pesticide residues, you must wash the grapes before eating them with their skins. It is best to rinse with water first, and use detergents that can effectively remove pesticide ingredients, and wash for more than two minutes. However, it is not advisable to soak in water or salt water, because soaking in water can easily promote the penetration of residual pesticides on the surface of the grapes into the pulp. American experts recently found that grape skins contain highly effective anti-cancer substances. They remind everyone to "eat grapes without spitting out the grape skins."
Researchers extracted hundreds of natural compounds from plants consumed by humans. They conducted repeated tests on these compounds and finally discovered and determined the highly effective anti-cancer effect of this substance.
They fed experimental rats with skin cancer this substance for 18 weeks and then compared it with experimental rats with skin cancer who were not fed this food. They found that the experimental rats that ate this substance had fewer cancer cells. 68-98. Generally speaking, the occurrence of cancer can be roughly divided into three stages. First, the DNA of normal cells is damaged and the genetic factors of cancer are awakened; second, cell division accelerates and joins the cancerization process; third, the tumor worsens and begins to metastasize. Experts say that this substance has a highly inhibitory effect on all three stages of cancer. This substance exists to varying degrees in more than 70 kinds of plants including peanuts and grapes, especially in grape skins and red wine. This substance has no toxic or side effects on the human body and can be developed into an excellent natural cancer preventive drug.
How to peel grape skins
Method 1:
1. Use a small steel spoon to break the grapes from the middle, but do not cut off the bottom of the grape skins .
2. Break the grape flesh in half and the grape seeds will be exposed. Use a spoon to remove the seeds.
3. Use a spoon to scoop out the pulp.
Method 2:
1. Leave the grapes in the refrigerator for a while before taking them out.
2. Peel directly from top to bottom, and the skin will be easily torn off.
Tips: We are usually used to peeling from the opening. For grapes, we start from the pedicle. However, after peeling it off, we will find that we can only peel about the average amount. Skin, there is no way to start with the remaining half. The correct way is to start peeling from the small pointed area on the butt of the grape. This way, no matter whether the grape is soft or hard, it can be peeled off quickly, and the peeled pulp will be very complete.
How to wash grapes
Method 1: Pick the grapes one by one and put them into a basin of water. Keep the grapes intact without breaking the skins. Take an appropriate amount of water from the basin to cover the grapes and pour Add a tablespoon of flour, mix well, soak the grapes in the flour water, hold the grapes with your hands, stir and shake for 1-2 minutes, then rinse the sewage under running water, and finally rinse with cold boiling water before eating.
This is because flour is a very good natural sorbent and can "absorb" the dirt and grease attached to the surface of fruits and vegetables.
Method 2: Use the lid of a pan and put a clean towel on it; pour the moistened grapes into it, about the thickness of one layer of grapes at a time, and you can roll it. Hold the flat plate with both hands and rock it back and forth to roll the grapes evenly. In this way, the white frost on the grapes will disappear.
Method 3: Add salt to the grapes, stir evenly; soak for about 20 minutes, pour out the water; rinse with clean water;
Pay attention to the following points:
1: Grapes are best eaten immediately after washing. After washing, even if it is placed in the refrigerator, it will only last for 2-3 days;
2: When washing the grapes, use scissors to carefully cut open the junction between the stem and the fruit. Do not cut to the skin (broken skin can easily contaminate the pulp), and do not leave a small stem outside the fruit. (Grapes with stems left on their stems are not only difficult to clean, but also easy to pierce the skins of other grapes.) Pick out rotten grapes first. Never use "pulled" stems, as a hole will be left and the flesh will rot easily. After pruning the branches and stems, you can see that the junction with the grapes is smooth and complete. If you use a "stem" puller, the fibers of the fruit will be pulled out and the grapes will be damaged.
3: The white dirt on the grapes is mixed with spider silk, exudate, and insects and is not edible. Be sure to wash it before eating it (especially drinking it as juice).
4: The process of washing grapes should be as fast as possible within 3-4 minutes to prevent the grapes from absorbing water and bursting, making them prone to rot;
5: Grape skins are rich in nutrients, so it is best to It is best to eat them with the skin;
6: If you are worried about drug residues on the grapes, it is best to soak them in light salt water for 10-30 minutes after washing.
