Lead: Grapes are rich in vitamins and have high nutritional value. They eat in a variety of ways, both raw food and wine are delicious. However, grapes are a seasonal fruit. After a long time, it is difficult to find a figure, and the preservation time is short and perishable.

In order to keep the grapes delicious, people air-dry them in a special way, which can not only ensure the loss of nutrients, but also have different flavors.

Raisins are a great invention. Using some special techniques to dry grapes can not only retain the rich nutrition of grapes, but also have a different flavor than eating raisins alone. Some people have a strong concept of health preservation and will adjust their bodies by eating raisins. For example, before going to bed at night, some people soak their feet, and some people eat raisins, which can regulate their bodies.

Raisins are rich in potassium, polyphenols and dietary fiber.

The potassium content in 1. raisins is quite high, and the potassium content in100g raisins exceeds 700 mg. The reference intake of potassium for an adult is 2000mg per day, so eating a handful of 25g raisins can supply more than180mg of potassium. As a snack, this is already excellent.

2. Grapes are rich in polyphenols, some of which will be lost during drying, but most of them can still be preserved. In addition, raisins also contain grape seeds and skins that we don't usually eat. There are more polyphenols in these two substances than antioxidants in pulp.

3. Raisins are also a good source of dietary fiber. The dietary fiber content in 100g raisins is 3.3-4.5g, which is 6-9 times that of polished rice.

1. Look at the size.

When selecting raisins, we should not only pay attention to their size. The size is determined by the variety of raisins, but it doesn't mean they are sweet and delicious. When choosing a variety, buy a uniform grain size.

Look at the color

The color of raisins is determined by the variety of grapes. The main colors are red, black, yellow and green. Different colors determine the overall taste of raisins. When buying, you should choose according to your personal preference.

Raisins can't be exactly the same color. If you find raisins exactly the same, don't buy them.

Observe the degree of dryness

Raisins are dried by grapes and have low water content, which is beneficial to preservation. If we find raisins sticky, just grab a handful and don't buy them.

Taste the taste

When we buy raisins, we'd better have a taste. Vendors usually want us to have a taste. Taste it and you'll know if it's good. Just taste it, and then buy the taste we like.

Check impurities

Don't buy raisins with many impurities. Unsanitary. We should take a closer look. If there are a lot of impurities on the surface of raisins, don't buy them even if they are cheap. Eating them is easy to get sick.

Prevent dyeing

When we choose raisins, if they look even and bright, we should be careful whether the raisins are dyed or not, so we can buy less. Go home and soak in water for a few minutes. There is obvious color in the water, which indicates that this raisin is not good. Don't buy it.
