 Which Foods Should Never Have Their Vacuum Seals Broken?
Food vacuum sealers are really helpful pieces of equipment. However, there are some food items that should not be vacuum-sealed and others that need to be prepared in a particular way before they may be safely vacuum-sealed. These foods typically contain anaerobic bacteria, which is a type of bacteria that is able to flourish even in the absence of air and oxygen.

What are the disadvantages of using vacuum packaging for food

Food can be preserved by the use of vacuum sealers by first removing all oxygen from the area surrounding the food item, and then ensuring that the vacuum-sealed packaging remains airtight. Because anaerobic bacteria do not require oxygen to thrive, there is a possibility that the food could go bad. However, the absence of oxygen will actually accelerate the growth of pathogens that are already present in the food. This increases the likelihood that the food will become contaminated.



The shelf life of the vast majority of food items may be vastly extended by vacuum-sealing them, which can also save you some money and give you some extra time. In this post, we will discuss a few different food items that should not be vacuum-sealed as well as food items that need to undergo speedy preparation before they can be vacuum-sealed securely.



There Are Certain Foods That Should Never Be Vacuum Sealed

Uncooked Mushrooms

When vacuum sealed, new mushrooms may spoil more quickly due to the natural ripening process that they undergo. However, mushrooms that have been cooked will vacuum-seal quite well!

Fresh Bananas

It is possible to accelerate the ripening process of fresh bananas by vacuum sealing them. However, after they have been peeled and frozen, bananas can be vacuum-sealed in a manner that is not only completely safe but also quite simple.

Garlic and Onion, Chopped Raw

These food items give off a natural gas that may lead to a loss in the vacuum, which increases the likelihood that they will go bad. These foods should be stored in a vacuum.

Cheeses that aren't too firm

It is perfectly safe to vacuum-seal hard cheeses, but soft cheeses such as blue cheese, brie, camembert, ricotta, and other soft and unpasteurized cheeses can actually produce mold faster in a vacuum than in regular air. This is because a vacuum restricts the amount of oxygen that can reach the cheese's surface.

Vegetables That Have Just Been Prepared

Vegetables that are cooked in a hot steamer or steamed might provide steam that can break a vacuum. Therefore, it is very necessary to wait until the heated veggies have cooled down to room temperature before vacuum sealing them.



Complete Apples

Before vacuum sealing, the apples will need to have slices cut into them first. It is also advisable to give the apple slices a little coating of lemon juice as this will assist in preventing any discoloration that may occur.

Items Regarding Food That Need to Be Prepared Before Being Vacuum Sealed

There are certain foods that, in order to be safely vacuum sealed, require to first go through the process of blanching. When they are stored, many common vegetables release a natural gas. Because of this, if these veggies are placed in a bag that is vacuum-sealed, the gas will cause the vegetables to rot. Therefore, blanching veggies before vacuum sealing them is the recommended method to ensure their safety.

Blanching is a method of cooking in which a food product, typically a vegetable or fruit, is submerged in boiling water, withdrawn after a short period of time, and then immersed in frozen water or placed under cold running water to stop the cooking process. Blanching is also known as "shocking." After being blanched, the food items need to go through an appropriate drying process. After this point, it is acceptable to vacuum seal them and store them in the freezer for later use. The Cruciferae or Brassicaceae family is home to the majority of the vegetables that need to go through this procedure. Some examples of these plants are as follows:


Tong Choy


Brussel Sprouts






When used correctly, a vacuum sealer has a wide variety of applications around the house and has the potential to be an excellent time and money saver. Vacuum sealing is an effective method for preserving the freshness of a wide variety of perishable foods, including meat, vegetables, fruit, and other foods. After being hermetically sealed, the food can be kept in the freezer for an extended amount of time before being thawed, at which point it can be cooked or eaten. Sealing non-perishable things using a vacuum sealer is an effective method in and of itself.
