1Can the small black particles on the grape skin be eaten?

Can.

Black grapes are natural seedless grapes. In order to make the grapes larger, they are generally treated with gibberellins. The small granular bumps on the surface of the fruit are caused by the high concentration of gibberellins, which are also called "fruit thorns". The period of gibberellin treatment is the peak flowering period, which is forty to fifty days away from the grape picking period, so it will not be harmful to the human body if eaten.

2What is the white frost on the grape skin?

The white frost on the grape skin is harmless to the human body. This white frost is a sugar alcohol substance secreted by grapes, also known as fruit powder.

These white frosts have a protective effect on grapes. They can reduce water evaporation and prevent the grapes from losing water and shrinking quickly after being picked. This layer of white frost is insoluble in water and can prevent the formation of a humid environment on the grape skin, thereby reducing bacterial infection.

3 What are the benefits of eating grape skins

1. Protect your eyesight

Anthocyanin is a phytochemical found in most purple objects. It is a very strong antioxidant. In addition to effectively scavenging free radicals and delaying aging, it also enhances immunity, inhibits inflammation, fights allergies, prevents eye fatigue and enhances vision.

The reason why grape skins taste astringent when chewed is because they contain a good phytochemical called tannin. Tannin is also an antioxidant that can fight tumors and also has an anti-cancer effect.

Resveratrol is a polyphenol compound. In addition to grapes, this element is also found in foods such as peanuts and mulberries. It has strong biological activity and is a plant antitoxin produced to resist fungal invasion. In addition to making people energetic, this substance can also prevent cardiovascular and cerebrovascular diseases and fight cancer.

4. Fight against high blood sugar

Grape skins always contain natural pigments, which can actively promote the decomposition of sugars in the human body, effectively resist high blood sugar, and avoid indigestion problems caused by eating too many grapes.
