Description

 Vacuum sealers can be used to vacuum package most kinds of foods as well as household items. However, there are certain guidelines that should be followed to maximize the capabilities of your vacuum sealer:
Vegetables should not be vacuum sealed fresh. It is best to blanch them (place in boiling water until the are hot, yet still crunchy), then submerge in ice water to stop the cooking process. This will allow the vegetables to retain their color and firmness. You may then continue with the vacuum sealing. You can also freeze the fresh vegetables and then continue the vacuum sealing process. If this is not followed, they will emit a gas after they have been vacuum sealed that will interfere with the vacuum seal of the bag.
Any food, such as meat or fish, that is very moist, is best vacuum sealed after it has been frozen. The excess moisture in the food will interfere with the sealing phase. Likewise, more delicate foods, such as bread or fruit, which are likely to be compressed under the pressure of vacuum sealing should also be frozen first to help the product hold its shape.
