Apple with "sideways": why scientists believe that fruits with spots dangerous

Spanish scientists said that apples with such imperfections as stains and areas of rot that are dangerous to humans. This also applies to other fruits, but mostly to the apples. Why is there such a categorical statement and there are no errors? Many of us from childhood, never paid much attention to the defects on the fruit, in the best case, just removing them with a knife. Is there a danger, really?

Among the apples that had a little lay down, you can always find the fruits of the so-called "barrels". The so-called round rotten area on the surface, extending deep into the fruit and affect the very core. All belong to this unpleasant phenomenon in different ways. Some just throw the apples with the "barrels", while others do not pay attention to them, others allowed such tainted fruit for jam or pies.

We never really think about the nature of this decay. Meanwhile, scientists have known about her a lot. "Flank" appears in the result of the defeat of the Apple special kind of penicillin a fungus, but it is not dangerous, and the product of his life. In the focus of such lesions formed patulin is an organic substance having antibiotic properties, but have more dangerous properties than useful.

Patulin once used in veterinary medicine for treatment of animals against various infections, but due toxicity banned. Overdose of this substance could kill the patient, which is easily found out by conducting experiments on laboratory rodents. Fortunately, the deadly dose to patulin from spoiled fruit person can not.

But this does not mean that it is connecting to us safely. Constantly receiving patulin in small amounts, we are constantly exposed to its negative effects. Scientists have found that the substance causes mutations by damaging genes. Such action can cause cancer, therefore, conventionally patulin is considered to be a carcinogen.

Although scientists have not been able to identify the dangerous quantities of this compound, they strongly recommend avoiding products that contain patulin. First of all we are talking about fruits, which are considered the main source of this toxin to humans.

In most countries the number patulin in products of plant origin in control. Its permissible content in the vegetable and fruit juices is 50 µg/kg. also Check jam, jams and puree apples for these products the norm patulin is 25 µg/kg For baby food the ratio is even lower and should not exceed 10 µg/kg.

Carcinogen attacks us not only in apples, but also pears, and bananas, plums, apricots and grapes. Avoid contact with patolino quite easy, as we have taken from fallen or just unsightly fruit to make jams, toppings and juices.

This is wrong, because in place of the usual injury quickly begin to multiply penicillin fungi, and consequently, patulin is formed. Therefore, pregnant women are forbidden for use any damaged fruit and for diet is to select only perfect fruit.

Was discovered patulin and many varieties of cheeses, especially with mold. But the penicillin that grows on the surface of Roquefort or kambera does not produce a carcinogen in such amount as the fungus that lives on apples. But even that patulin that appeared in the cheese, not harmful to the human body, deactivated by the amino acid cysteine, contain sulfur.

It turns out that patulin, extremely resistant to heat and even acid, is destroyed ordinary. This feature of the hazardous substances used in industrial scale, but it can be applied at home. Effective means may be sulfur dioxide, but this compound is banned in most countries of the world to add to the juices.

Patulin negative impact can be minimized if you eat damaged fruit or a variety of them together with foods rich in sulfur. Unfortunately, to use this method practically impossible. The sulphur content sufficient to neutralize patulin found in garlic and onions and in cabbage. There is sulfur in eggs, meat, poultry and fish. Needless to say that almost all of these products are difficult to combine with the apples.

But to affect patulin is still possible. To do this, just need to eat food rich in sulfur compounds before apples. In this case, learned in advance a chemical element will "trap" insidious patulin in the body and there to make it irrelevant.

So what about the apples that have spoiled the flank? On this score there are different opinions. The study's authors, scientists from Spain, believe that if the rot has seized the Apple more than a third of the fruit without the slightest hesitation to throw away.If the damaged area is smaller, you can try to cut it, but you need to retreat from messed up place on all sides not less than 1 cm, which is not always possible, if the fruit is small. Some particularly cautious experts believe that it is better to refuse in General from any Apple, damage which is noticeable to the naked eye — it would be quieter.

The most radical fighters against the rotten apples argue his opinion to the fact that patulin is not only limited to a broken spot on the Apple and a small area around you. Dangerous carcinogen fully permeates the whole fruit, however, the farther away from the source of the rot, the lower its concentration.

Summarizing, we can say that each person must decide what to do with apples with defects. The fact is that sometimes, these fruits make up a large proportion of the crop that was given to hard work. But in any case, whether you accept the information from the Spanish biologists or not, knowledge about Pauline and its dangers will not be superfluous.

Yes, you know that proper storage of fruits and other plant products, can significantly reduce the risk of exposure to dangerous doses of penicillin toxin?
