Why do grapes run seedless? Can you eat ordinary without seeds?

The varieties are different and can be eaten, just like there is a seedless watermelon.

To know why, you need to understand the recipe of raisins. First of all, not all grapes can be made into raisins. It is necessary to choose the kind of varieties with thin skin and seedless, plump and soft flesh, beautiful appearance, and high sugar content, and generally use "seedless white", "seedless dew" and "rose fragrance" and "milk" with seeds as raw materials.

The raw material is seedless grapes, so it's no surprise that raisins are seedless. But the skin is thin and has no skin, is it removed when it is dried, or does it fall off by itself? If Piin is not supposed to shrink with the grapes and is so compact that they can't be seen together, what is going on?

We asked the people who specialize in making Xinjiang raisins, and the answer was: not skinless, but skinless, but you don't know. After choosing the grapes to make the raisins, they cut the bunches:

After harvesting, cut off the fruits that are too small and damaged, and cut the fruit bunches that are too large into several small bunches and lay a layer on the drying tray. There are many other processes, among which the soda treatment can explain why we don't feel the skin: in order to speed up the drying and shorten the water evaporation time, they have to be treated with lye.

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 the fruit after maceration treatment can be shortened by 8 to 10 days.

Then the 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, wet a little on the surface to continue to dry, until two-thirds of the fruit is dry, twist the fruit by hand without grape juice oozing, you can stack 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 finished product.

So the raisins are done, and the rest is the packaging. Now we know why raisins have no seeds and no seeds.

Genetically modified grapes are seedless and can be eaten, and watermelons are also seedless, so you can eat them.

Sure, that's seedless grapes that I eat a lot.

Of course, you can eat it.

Remember.

Seedless grapes can be eaten, and this is an excellent variety.

Grapes without seeds include Sunshine Rose grapes, mare's milk grapes, flame grapes, and summer black grapes.

1. Sunshine Rose grapes

Sunshine Rose grapes are native to Japan and are cultivated and planted after being introduced to China. The Sunshine Rose grape is a grape variety that can be eaten with the skin on its skin, its skin is green, the fruit is hard, and the flesh is crisp and tender. Sunshine Rose grape is one of the few pure sweet seedless grapes, with a sweetness of more than 16, not only has a strong fruity aroma, but also mixed with a floral aroma, known as the Hermès of grapes.

2. Mare's milk grapes

Mare's milk grapes are produced in the Xinjiang region of China. Due to the unique geographical environment and climatic conditions of Xinjiang, the mare's milk grapes grown are highly sweet, the flesh is delicate, crisp, soft and palatable, and they are seedless grapes, which can be eaten with skin. Mare's milk grapes can not only be eaten fresh, but also can be used to make dried fruits, and everyone's favorite raisins are made from mare's milk grapes.

3. Flame grapes

Flame seedless grapes are native to the United States and are also known as red light seedless, red pearl, frey seedless, etc. The fruit spikes of flame seedless grapes are large, conical, and compact, with a spike weight of 680-890 grams, and the berries are medium-compact, with nearly round grains and bright red or purple-red in color. The flesh is hard and crisp, the skin is thin, sweet and sour is palatable, and the quality is excellent.

4. Summer black grapes

Summer black grapes are native to Japan and belong to the Kyoho grape variety, which are planted in Jiangsu and Shandong in China. When ripe, the grapes are hard and have purple-black skins. The flesh is crisp and juicy, sweet and seedless, and it is a grape that can be eaten with the skin on.

There are also early-maturing and late-maturing varieties, so the first grapes to hit the market are Natsui, and when the market falls, Natsuei is the latest to withdraw from the market.

By spraying a certain concentration of gibberellin in the full flowering and young fruit stages of grapes, seedless grapes can inhibit seed development, promote fruit expansion, and obtain seedless grapes.

Most of the fruits eaten are fertilized by pollination of the pistil, which is dependent on the development of ovules. That is, if the ovules do not develop smoothly into seeds, the ovary will not be able to form fruits.

In agricultural production, seedless fruits can be obtained as long as "controlling seed development and providing sufficient amount of plant hormones" can be achieved, and there are three ways to achieve this: first, spraying a certain dose of plant hormones for the fruit to inhibit seed maturity and promote fruit development; secondly, haploid plants were obtained by hybridization, so that the plant itself could not produce seeds, and at the same time, exogenous spraying of plant hormones promoted fruit development. Third, look for plant mutants whose seeds are sterile but capable of producing hormones on their own, which are used to produce seedless fruits.

Among the common fruits, "seedless Jufeng" is produced by the first method. Kyoho grapes have their own seeds, but spraying a certain concentration of gibberellin at the full flowering and young fruit stages can inhibit seed development and promote fruit expansion, resulting in seedless Kyoho grapes.

The ancestors of grapes were propagated by seeds, and for various reasons, individual plants or branches mutated to produce seedless grapes, which were cultivated and preserved by people through vegetative reproduction, forming seedless varieties.

Seedless grapes can only be propagated by nutrient propagation such as cuttings and grafting.

Seedless grapes are not born? Is this treatment harmful to the body? Haiyan told the truth.

Honey, grapes can be eaten, but not too much, because the sugar content is relatively high, it is easy to increase blood sugar, but moderate moderation is beneficial, as for the seedless grapes are pure superstition.

You can eat it.

Seedless grapes can be obtained by spraying a certain concentration of gibberellin at the full flowering stage and young fruit stage, and gibberellin can inhibit seed development and promote fruit expansion.

Most edible fruits are formed by the expansion of the ovary after pistil pollination and fertilization, and the expansion of the ovary depends on the development of ovules. That is, if the ovules do not develop smoothly into seeds, the ovary cannot form fruits.

There is no significant nutritional difference between seedless and normal fruits. Although some seedless fruits use plant hormones during the growth process, they can be eaten with confidence. Because the plant hormones used in seedless fruits are chemically very different from animal hormones, their metabolic mechanisms are also different.

The various plant hormones used in agricultural production will not have the effect of animal hormones after ingestion into the human body.

Seedless grapes can be eaten, and there is a seedless variety in the grapes themselves, which is very nutritious and beneficial to the human body after eating. However, it should be noted that people with diabetes and diarrhea symptoms are not suitable for eating grapes, otherwise it will increase the burden on the body and is not conducive to recovery.

Seedless grapes can be eaten because there is a seedless grape in each grape variety, which is very nutritious and beneficial to the human body after eating. And this grape contains a lot of flavonoids, which is very helpful for maintenance**.

It should be noted that not everyone can eat grapes, for example, people with diabetes are not suitable to eat grapes, because grapes contain a lot of sugar, and eating too many grapes will increase the burden on the body and is not conducive to recovery.

In addition, people with diarrhea symptoms are not suitable for eating grapes, because grapes contain a lot of water, pectin and fiber, which have the effect of increasing intestinal smoothness and promoting gastrointestinal peristalsis, and such people eating grapes will aggravate the symptoms of diarrhea.

<>1. It is known that the round-seeded grapes are new varieties of grapes, not caused by hormones, and the salient characteristics of hormone grapes are that the peel and stems become hard and lignified, and the grapes become astringent. The stems of the grapes without hormones are loose and soft, and the grape juice is smooth and sweet.

2. Seedless grapes are triploid and have the same principle as seedless watermelons. Now the promotion area is quite large.
