FAQs

How does vacuum sealing prevent freezer burn on meat and vegetables?

Freezer burn occurs when air comes into contact with food surfaces, causing dehydration and oxidation. In the Australian climate, where freezers work hard to maintain temperatures, vacuum sealing is especially effective because it removes almost all the air from the packaging. By creating a hermetic seal, the moisture is locked inside the food, and the dry air of the freezer is kept out. This prevents the formation of ice crystals within the food fibres, ensuring that when you eventually defrost your steak or veggies, they retain their original texture, colour, and juicy flavour.

Can I use a vacuum sealer for liquids like soups or marinades?

While standard external vacuum sealers can be tricky with liquids because the suction can pull moisture into the pump, it is certainly possible with the right technique. For domestic machines, the best approach is to partially freeze the liquid into a solid or semi-solid state before sealing. Alternatively, professional-grade chamber vacuum sealers are designed specifically for this task, as they equalise pressure inside and outside the bag, allowing liquids to stay in place. Using the “moist” setting on advanced models or placing a folded paper towel at the top of the bag can also help prevent liquid interference.

Are vacuum sealer bags recyclable or reusable in Australia?

Many vacuum sealer bags used in Australia are made from high-quality, heavy-duty plastics that can be washed and reused, provided they haven’t contained raw meat or greasy foods. To reuse, simply cut the seal, wash the bag thoroughly with warm soapy water, and allow it to dry completely. For recycling, many of these bags are considered “soft plastics.” You should check with your local council or look for dedicated soft-plastic recycling bins at major supermarkets to ensure they are disposed of correctly. Manufacturers are also increasingly developing compostable and biodegradable film options to reduce environmental impact.

How much longer does vacuum sealing actually make food last?

Vacuum sealing can extend the shelf life of food by three to five times compared to conventional storage methods like plastic wrap or containers. For example, raw meat that usually lasts three days in the fridge can often stay fresh for up to nine days when vacuum-sealed. In the freezer, the results are even more dramatic; fish or poultry that might last six months in a standard freezer bag can remain in peak condition for up to two years. This longevity makes it an exceptional tool for Australian families looking to prepare bulk meals or store seasonal harvests.

Is it necessary to blanch vegetables before vacuum sealing them?

For the best long-term results, it is highly recommended to blanch most vegetables before sealing. Blanching—the process of briefly boiling then icing the produce—stops the enzymatic actions that cause loss of flavour, colour, and texture over time. It also cleans the surface of any bacteria. If you seal raw vegetables without blanching, they may continue to release gases inside the bag, which can cause the vacuum seal to expand and fail. Once blanched and dried thoroughly, the vegetables can be sealed and frozen, maintaining their “garden-fresh” quality for many months in your freezer.
