What is the difference between grapes and raisins in terms of nutrition?

Raisins are foods that are dried by grapes, and some additives are generally added, so the nutrition of grapes will definitely be better than raisins.

Fresh grapes are richer in vitamins, and some vitamins are not lost during the drying process, but the sugar content of raisins will be higher, because grapes produce some sugar during the drying process.

Fresh raisins, its nutrients, vitamin content is relatively high, if the rate of quality into raisins, its sugar content will be relatively high.

Grapes will have a little more vitamins, while raisins are sun-dried, and a lot of water and vitamins will be lost, leaving only a small amount of vitamins and most of the sugar.

Fresh grapes will be more complete in all aspects of vitamins, a little and raisins are not so complete, and there is no moisture, and it will be easy to catch fire.

In terms of nutritional value, the sample value of grapes is more than raisins, for example, fresh grapes have a layer of white substance on them, and the inner substance actually contains a lot of trace elements, which can make people's bodies healthier, and the sugar content of grapes is relatively lower than that of raisins, because raisins are concentrated after being dried, and the sugar content in them is greatly increased, which is not suitable for diabetics.

There is a difference!

It's like fresh meat and bacon. All have their own prominent substance content.

The nutrition of the two has its own characteristics: in terms of energy, protein, fat, carbohydrates, fiber and trace minerals, the content of raisins is several times that of fresh grapes; From the perspective of vitamins such as VA, carotene, retinol, VC, VE, etc., these vitamins in raisins have been lost, while fresh grapes are abundant. Therefore, on the whole, raisins are very advantageous for supplementing energy and trace elements, while fresh grapes are very good for supplementing vitamins, etc., no thanks.

It is recommended to eat grapes because compared to grapes, raisins lose a lot of dihydrogen oxide, which is the most important component of the human body. Fresh grapes have higher nutritional value and better taste, and fresh grapes can not only be eaten directly, but also can be juiced, and the juice can be cured.

Raisins are fresh grapes that have been dried and processed. Although grapes and raisins are the same substance, there is a difference in the nutritional value of the two.

First of all, both are rich in mineral elements such as glucose, calcium, iron, and vitamins such as vitamin B and C, as well as amino acids. But grapes also contain more tartaric acid, an antioxidant.

Raisins are a good tonic for children, women and people with physical weakness and anemia because of their reduced water content and relatively high sugar and iron content.

The nutritional value of grapes is more than that of raisins, for example, fresh grapes have a layer of white substance on them, and the inner layer of substances actually contains a lot of trace elements, which can make people's bodies healthier, and the sugar content of grapes is relatively lower than that of raisins, because raisins are concentrated after drying, and the sugar content in them is greatly increased, which is not suitable for diabetics.

In the process of drying raisins, vitamins, especially water-soluble vitamins, will be fully volatilized, so they will be consumed more. Raisins contain less vitamins and less variety than fresh grapes compared to fresh grapes. From an energy point of view, raisins will have a higher energy density because they lose water.

Raisins of the same weight contain more energy than fresh grapes because fresh grapes contain more water than raisins.

Grapes and raisins are two very common and delicious foods that many people love. You may wonder which of the two is more nutritious, grapes or raisins. What is the specific situation of the demolition?

1. Problem analysis

If we compare the usual 100 grams of grapes with 100 grams of raisins, the data proves that the nutritional value of raisins is indeed higher. But the actual situation is that 100 grams of grapes can only produce about 20 grams of raisins, so the comparison should be 500 grams of grapes versus 100 grams of raisins, at this time, there is no obvious difference in nutritional value between the two from the data alone.

2. Grape nutrition

Fresh grapes contain many vitamins and active substances (flavonoids, glycosides, etc.) that are not found in raisins, and some prebiotic factors will inevitably be destroyed in the process of drying, and vitamin A and vitamin B12 in fresh grapes will be evaporated. In addition, the beneficial substances such as resveratrol in the grape skin, proanthocyanidins in the grape seeds, and polymeric phenol in the pulp are all destroyed, so the nutritional value of fresh grapes is higher than that of fresh grapes.

3. Raisin nutrition

After fresh grapes are dried into raisins, the nutritional structure will change to a certain extent. The evaporation of fresh grapes leads to a higher sugar content in raisins, and the lack of active substances makes them almost impossible for people with high blood sugar and obesity. However, the benefit of raisins is that the increase in iron imitation content and sugar content can increase sufficient energy for people with weak and anemia, and the effect will be more obvious than that of fresh grapes.

In short, fresh grapes and raisins have their own merits.

Raisins are a kind of dried fruit food formed by a series of methods such as drying fresh grapes, and the nutritional content of raisins is almost no obvious difference from fresh grapes. The nutrients contained in raisins mainly include vitamins, sugar, carbohydrates and trace elements such as iron, potassium, magnesium, and folic acid.

How to make raisins:

1. Selection of raw materials: Dried grapes should be made with thin skin, plump and soft flesh, beautiful appearance and high sugar content. The fruit should be fully ripe, but not too ripe.

2. Cut the skewers: After harvesting, cut off the fruits that are too small and damaged, and cut the fruit bunches that are too large into several small skewers, and lay a layer on the drying pad.

3. Soda immersion treatment: In order to speed up drying and shorten the evaporation time of water, lye treatment can be used. Impregnation in a solution of sodium hydroxide at a concentration of 1 5 banknotes, thin skins can also be treated with sodium carbonate or a mixture of sodium carbonate and sodium hydroxide at a concentration of 3 6 seconds.

After the raw material is soaked in alkali, it is immediately rinsed in clean water. The drying time of late fruit after alkali immersion treatment can be shortened by 8 to 10 days. When drying white raisins, it is also necessary to smoke sulfur for 3 to 5 hours.

4. Exposure: Put the grapes into the drying tray, expose to the sun for about 10 days, when the surface is partially dry, you can turn it all over, put it on the surface layer and continue to dry it, until two-thirds of the fruit is dry, and when the fruit is not exuded by grape juice, you can fold the drying tray and dry it in the shade for a week. In sunny weather, the total drying time is about 20-25 days.

5. Softening: Stack the fruit bunches for 15 to 20 days to dry them evenly, and remove the fruit stalks at the same time, which is a product.

Differences: 1. The active ingredients are different.

Fresh grapes are high in active ingredients, and after the grapes have been dried, some of them are lost, which is also a disadvantage of raisins.

2. The sugar content is different.

The sugar content in fresh grapes is relatively small, and although fresh grapes also contain sugar, it is only about 8%-10%, which will not cause violent fluctuations in blood sugar.

3. The moisture is different.

There is a lot of water in fresh grapes, and the water in raisins can be said to be lost. However, grape skins and grape seeds, which have health benefits, cannot be fully consumed.

1. In terms of nutritional value, there is not much difference between the nutritional value of fresh grapes and raisins.

2. Fresh grapes have more complete nutrients and contain more active substances.

3. After the raisins are air-dried, the glucose content is higher, but some active substances will be lost.

4. Experts suggest that diabetic patients, if their blood sugar control is relatively good, they can eat a few fresh grapes every day, because grape skins and grape seeds contain substances that clear blood vessels and lower blood lipids, which are good for cardiovascular health. Raisins, on the other hand, are not recommended.

There is no big difference in the nutritional value of fresh grapes and raisins, but the nutritional composition of fresh grapes is more complete and rich in more active factors. When the raisins are dried, the glucose content will be high, but some of the active substances will be lost. Fresh grapes have a water content of about 85 percent, while raisins have a water content of only about 10 percent.

Due to water loss, raisins contain almost no water-soluble vitamins but are high in minerals.

100 grams of fresh grapes can barely produce 20 grams of raisins. So if you eat 100 grams of fresh grapes to replenish minerals, then you only need to eat about 20 grams of raisins to replenish the same amount of minerals. That's why raisins are rich in minerals.

However, fresh grapes are more valuable than raisins in terms of overall nutrition. Raisins have the effect of lowering cholesterol levels and preventing blood clots and cardiovascular diseases.

At the same time, raisins are also rich in flavonoids, which have antioxidant effects, can eliminate free radicals in the body, and delay aging. A large number of studies have also proved that raisins have anti-cancer effects, and the leukotriens in them can effectively prevent cells from becoming cancerous or hinder the reproduction of malignant tumors. You can eat some raisins every day, about thirty or forty grams, and after 15 days, you can improve iron deficiency anemia in the body, enhance immunity, and enhance digestion.

Grapes are high in sugar, and glucose is the main component. Grapes are rich in fruit acids that aid digestion. Eating the right amount of grapes can enhance the function of the spleen and stomach.

Grapes are suitable for most ordinary people.

Raisins are the concentrated products of grapes, the loss of water-soluble vitamins is more serious, and other nutrients are still there, for **, the same weight, the calories of raisins are many times higher than grapes, that is, it is easier to gain weight, so it is recommended to eat less raisins.

The nutritional content of fresh grapes and raisins is not the same, because the water content of fresh grapes is more than 85% and raisins.

Raisins with only and due to the evaporation of water contain almost no water-soluble vitamins, but they have a very high mineral content.

Grapes have a sugar content of up to 10%-30% and are dominated by glucose. The large amount of fruit acids in grapes helps digestion, and eating more grapes appropriately can strengthen the spleen and stomach. Grapes contain minerals calcium, potassium, phosphorus, iron, and a variety of vitamins B1, B2, B6, C and P, etc., as well as a variety of amino acids needed by the human body.

When grapes are made into raisins, they are relatively high in sugar and iron, making them a good tonic for women, children and people with infirm anemia. Raisins contain 77 percent carbohydrates, which are the most effective and effective element for replenishing physical strength and are very inexpensive. Raisins also contain potassium, phosphorus, calcium, magnesium and some B vitamins; Raisins are fat-free, cholesterol-free, low in sodium, and are not manufactured with preservatives, so they are particularly beneficial to health.

The effects of each are different, fresh grapes.

Sweet and sour appetizing and delicious, fruits supplement more vitamin C, raisins have a unique flavor, and polysaccharides.

Other minerals.

The difference in nutritional value between them is: grapes.

Dry is a food medicine that prolongs life. Benefits of raisins: According to a survey of the diet of long-lived elderly people in Xinjiang and Russia, their common food characteristics are"Raisins and yogurt"。

Raisin raisin is the fruit of various grapes of the grape family Grape family, also known as grass dragon pearl and peach.

Its nutrition has its own characteristics:

In terms of energy, protein, fat, carbohydrates, fiber and trace minerals, the content of raisins is several times that of fresh grapes;

From the perspective of vitamins such as VA, carotene, retinol, VC, VE, etc., these vitamins in raisins have been lost, while fresh grapes are abundant.

Therefore, on the whole, raisins are very advantageous for supplementing energy and trace elements, while fresh grapes are good for supplementing vitamins.
