The vacuum storage is a very simple system proposed by Agritech Store, with a whole series of machines and accessories, which consists in the elimination from the container air present or only of some gases, such as oxygen mainly responsible for the oxidation.
This technique is used efficaciemente also industrial and commercial level, in order to protect as well as food materials also of different nature from contamination by dust and microbes.
With this type of treatment is possible to keep a food longer because in the absence of air most of the microorganisms and bacteria can not develop.
It is a technique that retains the flavor, aroma, color and nutritional properties of food and is used both raw and cooked products, often combined with refrigeration.
The retention time of the products under vacuum and then extends, and may vary depending on the type of food.
For the vacuum bags are used or envelopes of plastic material, trays polyethylene, or aluminum treated for food use, whose thickness and thermal resistance varies depending on the type of food and of subsequent treatments.
In fact, after the creation of a vacuum, it is possible to subject the product to pasteurisation, cooking or refrigeration.
The bags and containers are impermeable to oxygen and moisture.
The main advantages are:
The arrest of the development of aerobic microorganisms;
The 'chemical changes due to oxygen (oxidation);
The freshness and protection from external penetrating odor.
The easy stacking and storage containers without sticking to the other, (for example in the freezer).
