A vacuum sealer is a kitchen appliance that removes air from a plastic bag before sealing it, creating an airtight seal. This process helps to preserve food by preventing the growth of bacteria and mold, which can cause food to spoil. Vacuum sealers are commonly used to store food for longer periods of time, such as for freezing or sous vide cooking.
There are many different types of vacuum sealers on the market, each with its own features and benefits. Some of the most important factors to consider when choosing a vacuum sealer include the size of the unit, the type of bags it uses, and the features it offers. Some vacuum sealers also have built-in features, such as a cutter or a scale, which can be convenient for some users.
