Can deformed fruits be eaten? At this time of year, it is the time when all kinds of fruits are on the market. Among all kinds of fresh and tender fruits, there are many odd-looking and uneven deformed fruits. When people choose fruits, of course, they choose smooth and fresh skins. Those fruits that look ugly will eventually be left behind.

among the people in China, there is a saying that cantaloupe and jujube are more delicious. On the other hand, it is said that these deformed fruits are suffering from plant cancer and cannot be eaten.

which statement is correct? Are these statements really scientific?

What causes these fruits to grow ugly

There are many factors that lead to the abnormal appearance of plants' fruits, including radiation. Some scientists have done experiments. After some crop seeds (such as peppers, etc.) are brought to satellites and irradiated by space rays, the fruits cultivated are not only enlarged, but also bright in color. But what causes the fruit variation needs to be further understood.

But besides radiation, there are physical adversities such as water shortage, low temperature, high temperature and strong light. Salinity, environmental pollution, diseases, insects, weeds and other factors will lead to the change of fruit shape. Professionally, these factors are all called adversity stress, which refers to environmental factors that exert harmful effects on plants, so that fruits cannot grow in normal environment. Since they are all harmful factors, does it mean that eating such fruit is harmful to human body? -

Not necessarily. For example, there is no evidence that radiation will harm human health. On the contrary, some foods irradiated by radiation are good for people's lives. For example, chestnuts irradiated by γ -rays can be stored for a longer time; After being irradiated by space rays, the cultivated fruits are not only enlarged and bright in color, but also rich in nutrition, which is beneficial to human body.

Therefore, there is a certain truth in the folk saying that crooked melons and cracked dates are delicious. In addition, there is a folk saying that "rotten peaches and plums are delicious".

? Why do the fruits with crooked melons and cracked dates taste better?

Why do the fruits with crooked melons and cracked dates taste better instead? Do plants also "produce talents under adversity"?

Fruits that grow under appropriate adversity stress tend to ripen more easily, because adversity stress often stimulates the release of ethylene in fruits, and ethylene is a substance that stimulates fruit ripening. This substance is the main component of the fruit ripening agent commonly used now.

ethylene can promote the conversion of starch accumulated in fruits into disaccharides (such as sucrose) or monosaccharides (such as glucose, fructose, etc.), and at the same time reduce the acidity of fruits. Some special fruits, such as persimmons, bananas, kiwis, etc., can't be eaten immediately after harvesting, but need to be left for a while. The persimmon just picked will taste astringent because it contains soluble tannins, and the release of ethylene can promote the transformation of soluble tannins into insoluble tannins, which will reduce the astringency of fruits. In the same way, during the storage of bananas and kiwifruit, ethylene will also induce the increase of soluble sugar content, the decrease of acidity and the synthesis of aromatic substances in the fruits, and the unique flavor will be reflected.

For those "rotten peaches and plums" bitten by pests or "crooked melons and cracked jujubes" caused by physical adversity, the accelerated synthesis of ethylene in the fruit can promote the increase of soluble sugar content and promote the early ripening of the fruit. Therefore, compared with those immature fruits, they have matured and the proper flavor of the fruits has begun to show. Therefore, from this perspective, the folk saying is also reasonable. However, since the mid-199s, China's fruit production area and output began to occupy the first place in the world, and it is still far ahead. People can't worry about eating fruits. Those "rotten peaches and plums" that seemed to be "delicious" can only be off-grade now, so it is not suitable to put them on the table at all, let alone enter the big market.

As early as the 198s, a square watermelon was cultivated and sold in Japan. This kind of watermelon was sought after by many people as soon as it went on the market, because it was so strange. This watermelon is even more delicious if it is said that the crooked melon and the cracked jujube are delicious. Is this the case-how was it cultivated?

Can grotesque fruits be artificial?

Wang Liangju told reporters that it is actually very simple to cultivate this strange fruit, as long as a square box is placed outside the fruit when the watermelon begins to bear fruit, and a larger square box will be replaced later until the watermelon matures. In this way, the grown watermelon is square.

In addition to square watermelons, there have been heart-shaped grapefruit and apples with auspicious characters on the market. In Wang Liangju's computer, the reporter saw many strange pictures of fruits, including a watermelon that grew into a clown's face, which was very cute.

It is also very simple to cultivate these exotic fruits. Heart-shaped grapefruit is just like a square watermelon. Set a mold for the fruit to grow. It is also easy to grow words on the fruit. The simple way is to stick a paper-cut before the fruit begins to change color. If you want to form concave characters on the fruit, the method is actually the same as making a square watermelon. Just put a mold on the outside, and engrave the required inscription on the mold. When the fruit is ripe, remove the mold, and you can see the fruit with concave and convex patterns.

It is said that this strange-looking fruit is not cheap, and it is several times or even dozens of times more expensive than ordinary fruit. So, are these distinctive fruits better than ordinary fruits in taste and nutrition?
