Are raisins without seeds safe? What's the difference between grapes and raisins?
When it comes to grapes, you can't help mentioning raisins. What's the difference between them? Some people say: grape skin is thick, raisin skin is thin; Raisins are sweeter and sour grapes; Raisins are long and grapes are round;

Is the frost on the grapes a pesticide?
When buying grapes, we often find a layer of hoarfrost attached to the surface of grapes. It is said that this is a residual pesticide and must be washed away.
In fact, this layer of hoarfrost is a sugar alcohol substance secreted by grapes themselves, and its scientific name is "fruit powder", which is non-toxic and harmless. In addition to grapes, there are fruits such as plums, blueberries and prunes on the surface. This layer of cream not only needs not to be washed clean, but also praises it.
Because in the long-term transportation and storage process, fruit powder may be ground off for various reasons, so there is fruit powder, that is, grapes are fresher.
Are seedless grapes harmful?
There is nothing magical about cultivating seedless grapes. The secret is to "cheat" flowers
Grape seed is actually the seed of grape, which is fertilized and developed by egg cells in flowers.
If you use a plant growth regulator (gibberellin) instead of pollinating the seeded grapes, you can fool the flowers into thinking that they have been fertilized and start to develop fruits, and finally you will get seedless grapes. This gibberellin is not terrible either. It is a kind of "plant hormone", which can be synthesized by plants themselves, so it is very safe. It can be used not only to cultivate seedless varieties, but also to help fruits grow better.
Eat safely.

How should I wash the grapes?
Grapes are delicious, but they are not easy to wash. I suggest you divide them into three steps:
First, flowing water washes away the floating dust and impurities on the surface;

After eating these, you can taste them. If it's no trouble, you can cut the grapes into small strings before washing them, which will be cleaner.
Are seedless raisins safe? Generally speaking, seedless grapes can be divided into two types. The first kind is seedless grapes. After the male parent crosses with the female parent, it comes out as seedless grapes. Another is that grapes have seeds, and grapes are treated with hormones to become seedless grapes.
The summer black we usually eat is a natural seedless variety, such as sunshine rose, which can be turned into seedless grapes after being treated with gibberellin and cytokinin at flowering stage. But the quality of grapes has not declined at all.
Fruit farmers usually use hormones before and after the grapes bloom. In order to make the grapes sit on the fruit, they use fruit-setting drugs. Grape growth itself needs hormones, and endogenous hormones include gibberellin, auxin, cytokinin, ethylene and abscisic acid.
Any one of these five endogenous hormones exists in fruits. We usually supplement hormones through the outside world in order to supplement the problem of insufficient grape hormones. In foreign countries, including the United States and Italy, hormones are used in many fruits in organic foods.
The use of hormones has two directions. The first is to reduce the amount of labor. For example, branches can be controlled by hormones because their vegetative growth is particularly vigorous. The second is to improve the quality of fruit.
Including taste and appearance quality. At present, the hormones used in grapes have no effect on human body. If chemicals are used, the taste and storage capacity of grapes will be reduced. More harm is caused by the decline of grape quality. There is no problem with personal safety hazards.
