Advantages and disadvantages of vacuum sealer
As with other foods, even keeping the bread in a vacuum can have advantages and disadvantages, but the former are much more numerous.
Among the advantages, first of all, it should be known that thanks to the absence of air, the vacuum prevents the proliferation of aerobic microbes, which improves the conservation of the bread itself, as well as other foods.
The lack of air also interrupts the oxidation process, due to oxygen, which prevents the chemical alteration of the bread. Thanks to this, the bread maintains its flavor and fragrance unaltered. The vacuum also manages to keep the freshness intact and keeps the bread away from bad smells.
However, not all bacteria stay away with the vacuum: in fact, there are anaerobic bacteria that grow in environments where oxygen is absent. And this is why, in industrial production, a particular gas is added, which prevents the development of these bacteria.
Other foods that can be vacuum-packed
Bread, therefore, is one of the main foods that can benefit most from vacuum preservation as air is one of the main enemies of this food. However, it is not the only food that can be vacuum-packed to keep food fresh and wholesome.
Even meat, fish, crustaceans, and many other foods can be kept fresh thanks to the action of the vacuum: it will be sufficient to pack the foods, remove the air, and you're done. You can store the food and be able to consume it even many days after putting it in a vacuum.
Even the liquid may be kept in a vacuum. However, to obtain a good result, a particular machine called "bell" must be used. It is a type of vacuum machine, however, which is very expensive and which is therefore recommended for those who have a restaurant or shop.
