Grape trivia
Buying tips
Look at the fruit stalks: Fresh grape stalks are bright green, and the adhesion between the fruit and the stalk is firm, and no fruit will fall when the grape bunch is carried by hand.
Look at the hoarfrost: Fresh grape peels have a layer of hoarfrost that will fall off when touched with your hands, and the thicker the hoarfrost, the better the quality. (Hoarfrost on grapes is a sugar alcohol secreted by fruits and vegetables themselves, also known as fruit powder, which is a natural substance that is biosynthesized.) Such compounds are insoluble in water and there is no need to wash them off. ）
Look at the fruit: good quality grapes, bright color, dark color, close distribution of fruits, uniform size, full and compact appearance, no wilting, no spots on the surface.
How to store
Friends who eat grapes often know that they are difficult to preserve, and if you don't finish them, they will spoil in 1-2 days, which is a pity. You might as well try the refrigerator method~
Uneaten grapes can't be put directly in the refrigerator, we need to deal with them first. After buying home, don't wash it all, wash as much as you eat.
First of all, cut the grapes that need to be preserved, pay attention to the need to leave a little stalk on the grapes, and do not cut the pulp. (Check the grapes, if there are particularly soft or spoiled grapes, pick them out in time to avoid affecting other grapes)
Then prepare a clean and dry crisper with a layer of clean paper on the bottom, then put the grapes in it, and put another layer of clean and dry paper on top when sealing. Then put the crisper in the refrigerator and store it.
Cleaning method
First cut off the grapes one by one with scissors, pay attention to leave some stems, do not cut the pulp, put them in the basin, and then add a little salt and flour, salt can sterilize and remove pesticide residues, and flour can adsorb the dirt on the surface of the grapes, and then rinse it several times with water, so that the grapes can be washed thoroughly.
How much to eat each day is appropriate
Grapes should not be eaten too much, and the daily limit should be 200~350 grams (about 20~30 pieces). However, people who are often constipated and have spleen and stomach deficiency should eat less, and the elderly with kidney dysfunction should eat with caution.
It is best consumed between meals and not on an empty stomach before or immediately after a meal.
Within 1 hour after eating grapes, it is not advisable to eat marine fish, shrimp, crab, milk and other foods rich in protein and calcium at the same time, because grapes contain fruit acid, which will not only affect the absorption of protein, but also stimulate the stomach and intestines in severe cases, followed by abdominal distention, abdominal pain, diarrhea, vomiting and other discomforts.
