Can the odd-shaped fruit be eaten on earth? Guidance of _'s nutrition
Can the odd-shaped fruit be eaten on earth? ,At this time of every year, it is exactly when a variety of fruits go on the market one after another, in a feast for the eyes, fresh water various tender fruits, do not lack some odd-shaped fruits with odd, full of bumps and holes feature. People certainly select the crust smoothly and freshly while selecting fruits, the fruit that those appearance seems ugly, will be chosen leaving finally.
Among the people in China, one kind of statements thinks, the date is more delicious that the aslant melon splits; And another statement just the opposite, say odd-shaped fruit these to take plant cancer, not good to eat.
Which kind of statement is correct on earth? Do these statements really have a scientific reason?
What reason let these fruits look ugly
There are a lot of factors causing the gains of the plant to be with odd-shaped feature, including radiation. Have scientist make, test, seed (such as hot pepper) some crop After being taken the satellite, shines by the space ray, the fruit cultivated, not only the fruit increases, but also bright in colour. But that some reasons cause the fruit to make a variation, need to further understand specifically.
But except radiation, loses physical adverse circumstance such as lacking, low temperature, high temperature, strong light for and the moisture, various factors such as saline and alkaline, environmental pollution, disease, worm, weeds will cause the shape change of the fruit, on the speciality, these factors are called the adverse circumstance and coerce, mean that has exerted the environmental factor of adverse effect to the plant, make fruit unable to grow under the normal environment. Since all adverse factors, whether then mean such a fruit has been eaten harmful to human bodily-
It needn't be. Such as radiation, evidence does not prove they will be detrimental to health at present, on the contrary, some food shining through the ray is beneficial to people's life. For example, the Chinese chestnut shining through - ray, can preserve for a longer time; The ray is shone by the space, the fruit cultivated, not merely the fruit increases, bright in colour, and nutritious, it is still beneficial to the human body.
So, said aslant melon splits there are certain reasons in a sense in the statement that the date is delicious among the people, in addition, one kind lets among the people " worm's peach rotten Li is delicious and incomparable" Statement.
Why is the date more delicious that the aslant melon splits
Why aslant melon split date fruit the can delicious instead, plant can " whether adverse circumstance produce talent " too (used at the end of a question)-
The fruit growing under the circumstances that the appropriate adverse circumstance is coerced is easier to become more and more ripe, because will often stimulate ethylene in the fruit to release to coerce more quickly in adverse circumstance, and ethylene stimulates a kind of ripe materials of fruit. Commonly used fruit ripener of now, the principal ingredients are this kind of material.
Ethylene can promote the starch accumulated in the fruit to transform into disaccharose (such as the cane sugar) Or monosaccharide is (such as glucose, fructose) ,Still can reduce the fruit acidity at the same time. Some special fruit such as persimmon, banana, kiwi fruit,etc., can not eat immediately after adopting and accepting, and need to put it for some time. Persimmon that take off just, can taste astringent mouth, it was because the inside would rather contain the soluble form, form would rather can promote the soluble form and would rather not be turned into solubly in release of ethylene, will reduce the astringent mouth sense of the fruit. Same reason, banana and kiwi fruit are put in the course after adopting, ethylene will induce the soluble carbohydrate material content rising, acidity dropping, fragrant material in the fruit to formate, the characterized flavor is embodied.
As to worm of those diseases " Have gripped " "worm peach rotten Li " Or the physical adverse circumstance causes " Aslant melon split date" ,Coerced by the adverse circumstance to influence before being ripe, ethylene is formated with higher speed in the fruit, can promote the material content of soluble carbohydrate to rise, it is early riper to promote the fruit. Therefore, as to those fruit not yet ripe, they have been already ripe, the due flavor of the fruit has already begun to embody. So, according to this kind of angle, the folk statement is reasonable. However, since middle period of the 1990s of last century, the fruit of our country produces the area and output and begins to occupy the first in the world, and still hold a safe lead now. People do not worry that can not eat fruits, original those seem " delicious and incomparable " "worm peach rotten Li " ,Seem now it can only be the substandard product, unsuitable to furnish with the dining table thoroughly, can't enter the large market even more.
As far back as the eighties of last century, someone cultivated a kind of square water-melon to sell in Japan, this kind of water-melon is pursued by a lot of persons once going on the market, because it is too strange and eccentric. If according to the delicious statement of the date of splitting of the aslant melon, this kind of water-melon is more delicious, fact so and it how cultivate, come out.
Can the grotesque fruit be artificial
The deep and vast good colt tells reporters, it is actually very simple to foster such peculiar fruit, only when the water-melon begin to fruit, one set of a square boxes outside the fruit, pass in the period of time and change another a bit bigger square box, until the water-melon is ripe. In this way, the water-melon grown is square.
Besides the square water-melon, heart-shaped shaddock, apple with pattern of lucky characters,etc. have appeared on the market, in the computer of the deep and vast good colt, reporters saw a lot of strange and eccentric fruit pictures, among them a water-melon grows into the clown's feature, very lovely.
It cultivates peculiar fruit these to be too very simple, heart-shaped shaddock if square water-melon the same, give fruit sets of pieces of mould to let growth their. Let at the fruit longer than wording, coming too easy, simple method a bit that begin, stick one right away getting all right paper-cut change color, in fruit. Form have sunken characters, actually right away as cooking the square water-melon method at fruit, one set of moulds, is but carved with the inscription of the need on the mould, wait for fruits ripely and remove the mould outside, can see that there are fruits of unsmooth sense pattern.
Several times even dozens of are double on it is said such grotesque fruit, the price is not cheap yet, more expensive than the ordinary fruiting. Then, these fruits out of the common, in mouthfeel and nutrition is better than the general fruit.
Is the date nutrition of splitting of the aslant melon more abundant?
It needn't be, and ordinary fruit matter differences in fact, just shapes are different. The mouthfeel of the fruit is mainly differentiating from several respects such as its sweet taste, tart flavor, perfume and moisture.
And the sugar of the fruit is accumulated, generally all have such a course, namely early in growth, mainly many candy materials such as starch are accumulated in the fruit. Fruit at this time too sweetless one o'clock, because material these to have sweet taste. But with the maturity process of the fruit, many carbohydrate materials will be turned into the monosaccharide or disaccharose material slowly, and the monosaccharide or disaccharose is sweet. When many candy materials are almost transformed, the monosaccharide or disaccharose is accumulated to certain extent, enter the maturity stage of fruit at this moment. A lot of fruits, the taste when 80%-90% are well done is the best, and the fruit taken off at this moment still can be stored for some time. When the carbohydrate material is transformed down, act as many candies are totally turned into the monosaccharide in the fruit, the monosaccharide is decomposed gradually, the fruit reaches hundred per cent ripely. Although the fruit mouthfeel at this moment is sweet, often lack the tart flavor, and should not have been put for a long time, need to eat up at once after taking off. If fruit cross hundred per cent familiar with, then, mouthfeel does not getting kind, because fruit have, breathe too. The monosaccharide in the fruit is breathed, consumed at this moment, the institutional framework of cell begins to disintegrate, some original characteristics, if real fragile degree is totally lost, organize softening, send the silk floss, water content drops, it is not delicious certainly.
No matter the fruit of the normal shape, or grotesque fruit, unavoidable such a growth course. So square water-melon or with word apple mouthfeel those, essence with ordinary fruit its too much to distinguish.
Though mouthfeel of fruit the change, then how about nutritive value, can some change and deep and vast good colt say, the nutrition of the fruit that we talk about, mainly include candy, protein, fat, mineral, vitamin, cellulose,etc., some nutriment that we take notice of among them, such as mineral and vitamin,etc., last 1% proportion in being at fruit,other moisture mainly. So, are influenced by the fact that the fruit coerced of adverse circumstance was not received too much either in nutrition, will because out of shape to become very kind to human body in they,
Moreover, it is useful to fruit to coerce not every adverse circumstance, sometimes run counter to desire instead. It can be disadvantageous to fruit that it is coerced that what adverse circumstance on earth-
Why turn the pumpkin into " The wood "
At first, this kind of method of suppressing fruit and growing with the stone or mould, there are certain drawbacks. The plant all have certain resisting and pressing ability to the pressure, people, but there is every one. Once someone took pumpkins to make and test, while beginning to grow from the fruit of the pumpkin, press the stone on the fruit, the weight of the natural stone is the fruit can be afforded to bear, then change the heavier stone as the fruit is growing up constantly, until fruit being ripe. When people cut this pumpkin, find it hard and incomparable, the pulp inside makes and looks like the wood too, difficult to eat. Deep and vast good colt say this is because fruit are bearing the pressure strengthened constantly, the cell wall is thickened constantly in fruit, it is close to arrange, the fiber is thickened, organize hardening. It is hard to be such a pumpkin just like stone, come, say, certainly is delicious from mouthfeel.
