Do you want to spit grape skin when eating grapes?
The grapes are delicious and have a high nutritional value.
Mature vitamins contain 15%-25% glucose and many kinds of minerals and vitamins that are beneficial to the human body.
銆€銆€Grape nutrients: Grapes contain 8%-10% sugar, vitamin A, B1, B2, C, protein, mineral potassium, phosphorus, iron, etc., and almost contain a variety of physiologically functional substances.
銆€銆€The function of the grape: The sugar in the grape is mainly glucose, which can be quickly absorbed by the body.
When the body has hypoglycemia, if the grape juice is added in time, the symptoms can be relieved quickly; French scientists have found that grapes can prevent thrombosis better than aspirin, and can lower the serum level and reduce the cohesiveness of platelets.It has a certain effect on the prevention of cardiovascular and cerebrovascular diseases; the flavonoids contained in grapes are a powerful antioxidant, which can resist aging and eliminate free radicals in the body; the grape contains an anti-cancer trace element (resveratrol), which canPrevent healthy cells from becoming cancerous and prevent the spread of macromolecules.
Grape juice can help patients with organ transplant surgery reduce rejection and promote early recovery.
銆€銆€How should grapes be preserved?
銆€銆€After buying the grapes, wrap them in paper and put them in the refrigerator for temporary storage. Do not use plastic bags, so that the frost on the surface of the grapes (when the refrigerator in the refrigerator is warm and cold) causes cracking and rot.
銆€銆€The best cleaning step for the grapes: When washing the grapes, remove the rotten grape fruit and use scissors to cut the grapes and the fruit and carefully cut them.
Do not cut the peel, it is easy to contaminate the flesh when washing after peeling, and do not leave a small section of fruit stalks. Grapes with small fruit stems are not easy to wash, and it is easy to stab other grapes.
Tip: Do not remove the fruit from the ear, so that the fruit stem will bring out the fruit brush in the grape grain, leaving a hole in the fruit grain, the pulp is easy to rot.
After cutting the spikes, you can see that the intersection with the grapes is complete.
Put the grapes in the pot, add a little water, squeeze some toothpaste in your hands, rub your hands and gently wash the grapes.
Drain the dirty water and rinse it off with water.
Rinse the water until there is no foam. Rinse it, put it into the sieve and drain it, then use a flat plate, put a clean towel, pour the grape into it, once a layer of grape thickness, shake the pan with both hands.Roll the grapes evenly.
In this way, the remaining water can be drained.
銆€銆€Special reminder: the whole washing process should be fast (within five minutes), so that the grapes will not swell and rot.
The above practices try to ensure that the grapes do not come into contact with excessive water before consumption. Otherwise, the grapes are easily cracked and rot, and most of the nutrients and active ingredients are lost.
In addition, the grapes should be washed when they are eaten, because it is easy to break after washing.
After washing, even in the refrigerator, it can only be placed for two or three days.
銆€銆€Should you eat the grapes?
銆€銆€The grape skin contains anthocyanins. In addition to anthocyanins, the grape skin also contains another antioxidant, resveratrol.
Both types of substances are beneficial to the human body.
銆€銆€So, when we eat grapes, are we even swallowing the belt seeds (the higher the content of proanthocyanidins in grape seeds) to get the protection of these powerful antioxidants?
銆€銆€First of all, the current food safety issues are becoming less and less satisfactory.
I have planted a grape before I have used it. I know that the amount of pesticide used in the grape is very large and it is very easy to produce grapes without spraying.
Commercially available grapes start with flowering results, generally 7?
Spray the fungicide once every 10 days, and in the later stage, in order to prevent the grape anthracnose from harming the grape fruit, it is necessary to spray the medicine for the ear.
銆€銆€These pesticides cannot be completely removed during the washing process.
At present, there are many detergents on the market that can remove pesticides on the surface of fruits. The actual effect is not as good as the promotion.
銆€銆€First, the antioxidants such as proanthocyanidins and resveratrol in grapes are not highly soluble in water (resveratrol is more difficult to dissolve in water).
People who have studied nutrition know that nutrients must be dissolved in water or trace amounts to be absorbed by the body.
Low solubility means that most of the nutrients will 鈥減ass through鈥?and fail to achieve the desired effect.
銆€銆€Therefore, for your own health, safety, or painstakingly abandon the rich cellulose contained in the grape skin and the antioxidants that are not easily absorbed.
