The "vacuum" is a food preservation technique that is done by removing air from the inside of a container by suction. As a consequence, the food present inside the container is found in a condition of environmental pressure.
To induce vacuum in food, two basic components are needed: the machine and the containers. The vacuum machine, also called vacuum , is an instrument that extracts the air from the bag containing the food and seals it. The effectiveness of the method is mainly linked to the elimination of oxygen. This gas is a powerful oxidizing agent and causes food to brown. Moreover, a part of the microorganisms responsible for food degeneration is of the aerobic type, that is, it lives and multiplies thanks to the presence of oxygen.
In addition to preservability, the following advantages are also observed:
A greater freshness of food at the time of use, therefore an optimal maintenance of color, aroma and taste;
Exceptional preservation of food liquids.
This last point therefore allows to gain greater food yield and lower the costs of raw materials.
