The greatest benefit to the body comes from eating fresh fruits and vegetables. They contain many useful vitamins and minerals. The traditional canning has been replaced by a vacuum system, which allows us to preserve the freshness of products. "VAKS" - a device for canning by creating a vacuum. Let's take a closer look at how this simple mechanism works.
WAX - what is it?
Preserving fruits, vegetables and various foods can significantly extend their shelf life. Conventional canning involves preliminary heat treatment of products. A more modern method of harvesting is the vacuum system "VAKS". Recently, the device is used more and more often, because the products are much better stored in a vacuum. This avoids oxidation and damage to the preservation. Indeed, under a metal or nylon cover, gases are gradually collected, which lead to spontaneous opening of the workpiece.
Originally availablea set of special caps (9 pieces) and a pump to create a vacuum in the container. The manufacturer made sure that the product is suitable for all consumers, and therefore offers several options for the diameter of the caps. This means that when preserving drinks and food in non-standard containers, housewives will not have problems.
The vacuum canning system has become a godsend for many. With its help, it is possible to pump out air from a glass container for canning without any problems. This system can be used to store groceries at home or while traveling.
System Benefits
An original Russian-made invention is used to preserve all kinds of products and preserve the maximum amount of useful substances. Vacuum caps can be used up to 200 times. They completely replace the usual metal ones, which are always used for preservation.
Vacuum canning is used to prepare food for the winter and to prolong the freshness of cereals, pasta, flour, drying fruits and berries. The latter are usually simply dried and stored in containers. However, most often, various bugs are planted in dried fruits, after which the product is no longer usable. The vacuum system avoids the appearance of parasites in food during long-term storage.
The air pump plays the role of a seaming key. Only, using this simple device, there is absolutely no need to make efforts and try to roll up the lid. Enoughjust make a few movements, and the container with the product will be securely closed. Special lids for vacuum preservation do not leave chips and cracks on glass containers when opened. They are equipped with a valve through which air is pumped out.
Scope of application
The most natural way to store perishable products is vacuuming. If some time ago such a technique was not available for use at home, then with the advent of the VAKS system, everything became a reality. It is used not only for traditional canning. The method is suitable for use in the following cases:
- bulk storage;
- prepared food storage;
- storage of dairy products, cheeses;
- storing fresh herbs;
- storage of sausage products;
- storage of fresh juices from fruits and vegetables.
If you pre-dry fruits, vegetables or berries in a dryer, their shelf life in a vacuum increases several times. The vacuum canning system can be used to marinate meat and fish delicacies. Under such conditions, the marinade penetrates the food faster.
"WAKS" allows you to re-preserve products after opening. This means that if you open a product and do not use it completely, you can close the glass container again with the same lid.
Disadvantages of the method
Despite its many advantages, the system also has somelimitations. First of all, it concerns the cost of the device. Vacuum covers "VAKS" and the pump will cost consumers 750-800 rubles (standard). Sometimes you can find cheaper deals, but according to reviews, these are non-original products. The manufacturer also produces a set that includes an increased number of caps (28 pieces). The cost of such a system is at least 1,300 rubles.
In some cases, conventional lids should still be used for preservation. Some housewives complain that the VAKS vacuum system cannot cope with the preservation of cucumbers, tomatoes.
How to use?
To keep food fresh for a long time, it is important to know how to use the canning system correctly. First of all, you should pay attention to the glass container that will be used. It should not be chipped or otherwise damaged.
Before installing the lid on the neck of the container, it is necessary to check the tightness of the seals. They must be fully seated in the grooves. After that, a pump is inserted into the hole on the lid, and the air is pumped out of the tank by moving the rod up and down. Such actions must be performed no more than 5. If longer storage of products is necessary, about 15 rod movements are performed.
To open the container, you just need to lift the valve on the lid. Do not use sharp objects for this.
VAKS vacuum system: reviews
The device is considered new onmarket, but, despite this, has already managed to earn a lot of positive recommendations. Vacuum storage keeps most perishable foods fresh.
When properly used, the air pump will last a long time. Periodically, it must be disassembled, washed, dried and lubricated with petroleum jelly. If the cuff of the pump is rough, it should be held in hot water. If this manipulation does not bring the desired result, it must be replaced.
To make sure that the vacuum system is working, you need to draw a small amount of water into the container, close the lid and pump out the air with a pump. The jar is then turned over. The appearance of air bubbles indicates a breakdown of the system.
