The answer is YES . But bread is soft and contains air-filled chambers, how can I do to prevent it to be over vacuuming ?
Freezing before vacuum
The easiest way to safely seal your bread is to freeze it first. This will make the bread rigid enough that it won't crush when the air is vacuumed out. Simply place the bread you want to seal on a pan or other freezer-safe dish and place it in the freezer for a couple of hours. Once it has been thoroughly frozen, pull it out, place it in a vacuum seal bag, and proceed to vacuum and seal it. Freezing your bread first is a method that works with any vacuum sealer machine.
Some vacuum sealers will allow you to seal unfrozen bread by using a "pulse" setting. With this setting, the machine will remove only as much air as you tell it to. By controlling the amount of air removed, you can stop the vacuum process and seal the bag before the bread is crushed. The exact process varies by machine, so check your vacuum sealer's instruction booklet for more information.
No matter which method you choose, the cost savings of sealing breads, over letting them get moldy on the counter, is worth the effort.
