5 home hazards conservation

Cooking conservation of his fruits and vegetables - this is, of course, wonderful. But do not forget that they can harm health. How to avoid it?

Pickles and preserves

- It is believed that at home salting killed all the useful items, - says our expert dietician Lyudmila Denisenko. - Yes, vitamin C is decomposed by heat treatment - about 70 percent of his stock disappeared from thermally processed fruits and vegetables. But the antioxidants lycopene and beta-carotene (from carrots and tomatoes) are not only perfectly preserved, but even improve their properties. Also, nowhere is not lost during preservation calcium, magnesium and other minerals. But without pickles, jams winter table will still be poor. So do them, certainly worth it, but do not forget - if you have any contraindications, it is better not to get involved strongly pickles. Even healthy people feast on them is no more than once or twice a week.

Aspirin allergy

Many housewives still prefer to throw aspirin to prevent fermentation. But remember - it is able to cause allergies! Particularly careful with aspirin use to be for people suffering from asthma, sinusitis (inflammation of the nasal passages frequently) and urticaria.

Stone fruit jam can be poisoned

Any jam - not for diabetics and dieters.

And very important: in the nuclei of almost all stone fruit (including cherries and peaches) contains a substance amygdalin. Once in our body, it is converted to prussic acid - one of the most dangerous poisons. But do not be so afraid of - fresh and freshly preserved berries with seeds contain small amounts of amygdalin, it is not dangerous to health. But the longer the jam is stored, the more hazardous substance therein. Therefore, all work with seeds can be stored for no longer than a year. By the way, not worth the risk, giving such compotes and jams from stone to children under 12 years. Of course, if the berries were preserved fruits seedless, they are safe.

Vinegar and salt dangerous for the kidneys.

Any pickles, but most marinades can be dangerous for people with diseased kidneys, problems with the gastrointestinal tract. And also for those who are prone to edema, and hypertension. Of course, just abandon the home delicacies not necessary, but restrict them still have.

Oil spurs pancreatitis

Lots of salads prepared with the addition of a fair amount of oil. This, of course, inevitable. Yet such blanks should not get involved people with pancreatitis, cholecystitis, etc. And remember - In spite of the benefits, a large number of oil - it is also high in calories.

Wrinkled barrel - the source of the fungus

The best way to preserve Kripen'ka rosy apples, berries are not wrinkled, and not spoiled tomatoes.

- The fact that all the bruising, bruising and brown flanks of fruits and vegetables - a source of fungi, - says Lyudmila Denisenko. - A mold produces a hazardous compound - patulin. Even if you carefully will cut a beaten side, and the rest finely crumble and spend the heat treatment, it will not protect you from infection. Moulds affect the whole fruit. And if in fresh apples, tomatoes, berries patulin can cause food poisoning, then he will not get anywhere in the blanks. This resistant virus is not killed by boiling, frying and sautéing (generally rotten tomatoes to use is not worth it in the roasting in the soup). Over time, in billets, in which were affected by a fungus vegetables and fruits, the poison is released gradually destroys the liver. So it is not worth the risk. Tainted fruits send to the compost, and banks - just good!

- Still, the most correct way of harvesting the wealth of summer - frost - said to m n Michael Zeigarnik. - In such vegetables and fruits preserved far more vitamins and minerals than cooked. The only negative is perhaps the aesthetic. Ice crystals rupture the structure of frozen pieces, so the views are not as beautiful as in a jam.

- Strictly speaking, little has changed canning - agronomist says Mikhail Vorobyov. - There is still boiling - the main way of blanks. The most important invention of the last decades can be considered as a screw on the half-turn cover. It is much easier work of housewives who prefer to harvest your vegetables and berries for the winter.

There are also vacuum cover, the air from under the special pump which is evacuated, and the workpiece is stored longer. So far, however, widespread, they have not received.

And, of course, is still relevant sterilized jars. In the usual course of the old methods, but the civilization comes to the aid of the hosts.

Sterilizing with steam over a pan of boiling water to put the lattice on which banks are set upside down. Now even invented a special attachment to the pan, which facilitates a steam process. Warning - you can get burned by steam.

Wet banks are put in the oven, preheated to 160 degrees, and are dried until complete evaporation of the droplets from the walls. The risk that banks could burst.

At the bottom of the banks, pour a little water and put in the microwave at maximum power for 2 - 3 minutes.

The dishwasher can be sterilized once a lot of cans - used high-temperature mode.

Electric household sterilizer. In fact - this is home autoclave. There is placed just a lot of cans. But should such a device a lot.
