The autumn wind is blowing, and it is the season when grapes are on the market in large quantities. Looking at the clusters of plump, delicate and charming grapes of various colors on the fruit stall, can’t saliva help flowing out?
Vitis vinifera is a plant belonging to the genus Vitis of Viaceae, which belongs to berry fruits. Listening to this classification can remind people of the juicy taste of grapes.
Grape is planted in a wide range of areas, including large areas in temperate and subtropical zones, forming a huge [grape dynasty] with a large number of varieties.
There are more than ten common grape varieties on the market in our country, such as Jufeng, Rose Fragrance, Beauty Finger, Mare Milk, Qingti, Hongti, etc.
Different varieties of grapes have different colors, sizes and shapes, and different tastes. Whether they love sweet taste or slightly sour taste, the large family of grapes can meet your needs.
Delicious and nutritious
Fresh grapes are attractive in color, refreshing in aroma, sweet and sour, and have become very popular with people. Grapes are widely used in the food processing industry. Besides well-known wines, they can also be used to produce jam, fruit juice, jelly, raisins and other different products.
Grapes are not only delicious, but also of high nutritional value.
Fresh grapes still account for the vast majority of water, up to 88%. Grapes are rich in potassium, vitamin A, vitamin C and B vitamins, which are good sources for people to obtain vitamins.
And we are familiar with grape products, raisins, can be called concentrated essence. After drying, the concentration of iron in raisins is greatly increased. Because of its delicious taste, it is easy to be accepted by people. It is a good supplementary food to supplement iron. Patients with iron deficiency anemia and women can eat more, which is helpful to improve hematopoietic function.
The magical health care function of grapes?
People may be more concerned about the health care function of grapes than the delicious taste of grapes.
Legend has it that grapes can resist oxidation and aging, which is related to some plant antioxidant substances in grapes, of which resveratrol is the most famous.
In many studies, it has been found that it can prevent aging caused by free radicals and lipid peroxidation in the body, and can also inhibit cytopathic changes to reduce the probability of cancer.
Resveratrol is the most abundant substance in grape seeds and grape skins.
So some people began to use their imagination. Since resveratrol in grape skins and seeds is so good, when I eat grapes, I will eat grape skins and seeds together, which can resist cancer and aging.
So, is this statement reasonable?
In fact, although resveratrol was found to have certain anti-cancer and anti-aging effects in the experiment, in our daily life, the amount of grapes eaten is really limited, which is still far from the amount used in the experiment.
How many grape skins and seeds do you have to eat to reach the effective amount in the experiment? The most important thing is that the grape skins and seeds are not delicious either. It is good for us to enjoy the delicious grape and don’t be too superstitious about its health effect.
Moreover, there is not enough evidence that antioxidants such as resveratrol are really beneficial to human body. The more resveratrol, the better. Some studies have found that too much resveratrol can also promote the growth of cancer cells.
Therefore, it is not necessary for everyone to buy so-called health products for resveratrol.
What is the white frost on grapes?
When buying grapes, you often see a layer of white frost on the surface of the grapes. Many people worry that the white frost is dirty, so they wash the grapes with white frost many times, even with starch and salt water.
In fact, this layer of white frost is brought from the mother’s womb by grapes. Its name is [fruit powder]. Fruit powder is sugar alcohol secreted by grapes themselves and is harmless to human body.
Therefore, the next time you wash grapes, don’t give yourself any trouble. This layer of white frost doesn’t need to be washed off.
In addition, in long-term transportation and storage, fruit powder may be wiped off for various reasons, so this tells us a little trick to select grapes: having fruit powder means grapes are fresher.
In addition to grapes, plum, blueberry, prune and other fruits have similar white frost on their surfaces. Therefore, when selecting these fruits, you can also refer to this method.
What is the difference between grapes and raisins?
Here, I have to mention the raison.
Often some people [grapes] [raisins] are confused. When they buy grapes, they often carry back a bag of raisins.
So, what is the difference between grapes and raisins in what?
As mentioned earlier, the family of grapes is huge. There are more than 60 kinds of grape plants in the world, and raisins are also a variety of Eurasian grapes.
Therefore, in essence, there is not much difference between the two. There is a saying that [raisin], which means [grape] in Cantonese, is the name of a commodity.
Of course, there are still differences in taste and mouthfeel between grapes and raisins. For example, the pulp of raisins is crisp and the peel is not so easy to separate, which can also be used as a general feature to distinguish [ordinary grapes] from [raisins].
There is another difference, I believe everyone has also found, that is, the price of raisins is more expensive.
