Frequently Asked Questions

How does a vacuum sealer machine prevent freezer burn?

Freezer burn occurs when air comes into contact with food surfaces, causing dehydration and oxidation in the cold environment. A vacuum sealer machine removes almost all the air from the packaging before creating a heat-fused seal, ensuring that no oxygen can reach the food. By eliminating the air, moisture is locked inside the item, and the protective barrier prevents ice crystals from forming directly on the food. This process keeps your meat, vegetables, and pre-prepared meals looking and tasting fresh for much longer than traditional storage methods like freezer bags or plastic wrap.

Can I vacuum seal delicate or liquid-based foods?

Yes, many modern vacuum sealers include a “pulse” function or a “gentle” setting specifically designed for delicate items like berries or pastries, allowing you to stop the suction before the food is crushed. For liquids such as soups or stews, it is often best to pre-freeze the liquid in a container until it is solid before vacuum sealing it in a bag. Alternatively, some advanced machines feature a moist or liquid mode that manages the vacuum process to prevent fluids from being sucked into the pump, ensuring a secure seal without making a mess or damaging the machine’s internal components.

What types of bags are compatible with external vacuum sealers?

External vacuum sealers typically require specific “channelled” or “embossed” bags that have a textured internal surface. These tiny ridges or channels are essential because they allow the machine to draw the air out effectively when the bag is closed. Smooth bags, which are often used in commercial chamber sealers, will generally not work with domestic external machines because the two smooth sides press together and prevent the air from being extracted. Using the correct Australian-standard embossed bags or rolls ensures a high-quality vacuum and a reliable heat seal that will withstand long-term storage in the pantry or freezer.

Is it necessary to refrigerate food after it has been vacuum sealed?

Vacuum sealing is a preservation aid, but it is not a substitute for proper temperature control. While the process removes oxygen to slow down spoilage and prevent mould growth, certain types of bacteria can still thrive in anaerobic environments. Therefore, perishable items such as fresh meats, dairy, and cooked leftovers must still be stored in the refrigerator or freezer after sealing. Vacuum sealing significantly extends the life of these refrigerated items, but it does not make them shelf-stable like commercial canning or heat-sterilisation processes would, so following standard food safety guidelines remains vital.

How do I maintain my vacuum sealer for long-term use?

To keep your machine in top condition, you should regularly wipe down the vacuum chamber and the sealing strip with a damp cloth to remove any food residue or liquid. It is important to inspect the foam gaskets periodically, as these can become compressed or cracked over time, leading to air leaks; many Australian suppliers offer replacement gaskets when needed. When storing the machine, ensure the lid is closed but not locked, as keeping it under constant pressure can deform the gaskets. Routine cleaning and careful handling of the heating element will ensure consistent, airtight seals for many years of operation.
