What is vacuum packing and how does it work?
Vacuum packing is a method of preserving food by removing air from the packaging before sealing it. This process significantly reduces the amount of oxygen that comes into contact with the food, which can slow down oxidation and the growth of bacteria. By creating a vacuum-sealed environment, food can last much longer compared to conventional storage methods.
In addition to its preservation benefits, vacuum packing also serves to save space. The absence of air allows the food to be packed more tightly, which is especially helpful for items like clothes, bedding, or even bulky foods. Vacuum packing is commonly achieved using specialized machines, which draw out the air and seal the package in one automated process.
What types of foods can be vacuum packed?
Most types of food can be vacuum packed, including meats, vegetables, fruits, and dry goods like nuts and grains. However, it’s essential to consider the moisture content of the food. Solid items that are less moist are generally better suited for vacuum packing, as high moisture levels can lead to spoilage or the growth of mold.
Some foods, such as soft cheeses or delicate vegetables, can be vacuum packed with care. It’s important to partially freeze these items or use a gentle setting if your vacuum packing machine has one. Vacuum packing can also be an effective way to store leftovers, reduce food waste, and keep pantry items fresh for longer.

Generally, vacuum-sealed meats can last in the freezer for up to two to three years, while vegetables can last approximately 8 to 12 months. The absence of air helps extend the freshness of the food well beyond the typical refrigerator shelf life.
For dry goods, vacuum packing can keep items fresh for months or even years, depending on the storage environment. It’s crucial to store vacuum-packed food properly, as light, heat, and moisture can still cause food to deteriorate even in a vacuum-sealed bag. Always label and date your vacuum-packed items to monitor their freshness.
Is vacuum packing suitable for sous vide cooking?
Yes, vacuum packing is highly suitable for sous vide cooking. In fact, it’s one of the essential techniques used in this cooking method. Sous vide involves cooking food in a water bath at precise temperatures for extended periods, and vacuum packing ensures that the food is sealed tightly, preventing water from entering and diluting flavors.
Using vacuum-sealed bags for sous vide also helps to maintain the food’s moisture, which leads to a more flavorful and tender outcome. Additionally, vacuum packing eliminates the risk of food contamination from the water bath, making it a safe and effective method for cooking a wide variety of foods.
Can I vacuum pack liquids and how do I do it?
Vacuum packing liquids can be challenging but is possible with the right techniques. To vacuum pack liquids such as soups or marinades, it’s advisable to freeze the liquid in a container or tray until it solidifies. Once frozen, transfer the solidified liquid into a vacuum seal bag for sealing. This way, you prevent the liquid from being sucked into the machine during the sealing process.
Another option is to use vacuum-packable bags designed for liquids, which often come with special features to contain spills. Always leave enough space at the top of the bag, as the liquid may expand when frozen. Remember that vacuum sealing liquids may reduce their shelf life in the fridge, so it’s often best done for freezer storage.
Can I reuse vacuum-sealed bags?
