Does fresh mozzarella have to be refrigerated if vacuum sealed?

Fresh mozzarella needs to be refrigerated regardless of whether it's vacuum sealed or not. Vacuum sealing may extend its shelf life slightly by preventing air from reaching it, but it does not make the cheese shelf stable.

Fresh mozzarella is usually sold in a liquid brine, which helps preserve it. However, the cheese is still highly perishable and should be kept cold to prevent it from spoiling.

Refrigerate unopened fresh mozzarella in its original packaging until the best by date. Once the cheese is opened, it should be consumed within a few days.

If you vacuum seal the cheese yourself, be sure to use a food-grade vacuum sealer and vacuum bags. This will help to prevent the cheese from coming into contact with air, which can cause it to spoil.

Vacuum-sealed fresh mozzarella can be stored in the refrigerator for up to two weeks. However, it's best to consume the cheese as soon as possible for the best flavor and texture.
