Vacuum sealing food is indeed an excellent choice, but it also has disadvantages. The disadvantages of vacuum-sealing food are that it can damage the flavor and the texture of certain foods. Vacuum sealing food may cause its surface to dry out, which would make it lose flavor rapidly after opening.
Some people say that vacuum-sealed food doesn’t look as appetizing as packed or canned food, because their appearance becomes dry and apparently flatter. Furthermore, the process of vacuum-sealing food may cause certain vitamins to break down, which would eventually result in the loss of nutrients. The system of removing air from the packaging causes oxidation; this causes flavor and nutrient degradation because it speeds up spoiling.
Disadvantages of Vacuum Sealing Foods To Follow
There are some key disadvantages of vacuum-sealing food such as dry food, crushed or cracked food, Lack of Nutrients, browning of some foods that are sensitive to this process. Some of the flaws of this practice are described below.
1) Dry food
A big disadvantage of vacuum-sealing foods is that it can make them parched. When the air is removed from the packaging by a vacuum sealer, it takes away the food’s natural moisture. This is a problem because it can lead to a loss of flavor and make the food more susceptible to spoilage.
2) Crushed or cracked food
Sealing can lead to the crushing or cracking of some foods. This happens because when the air is removed from the packaging, it creates a vacuum that can cause food to expand. If there is already something fragile about the food- like a crack or a fracture- then it will probably break under the pressure.
3) Browning of some foods
Certain foods, such as apples or bananas- can brown quickly when they are exposed to air. This happens because the enzymes in the food react with oxygen and cause a dark pigment to develop. If these kinds of foods are packed in a vacuum bag, then their cells will collapse under pressure. The lack of space within the packaging means there is nothing to resist the enzymes and oxygen from coming into contact.
4) Nutrients: oxidation
Vacuum-sealing can speed up the spoiling process and lead to nutrient degradation because it causes oxidation. When you remove air from food packaging, there is nothing left to protect the food from oxygen, so it breaks down immediately. This also applies when frozen foods are taken out of their packages and exposed to air. The process of vacuum-sealing food can cause certain nutrients to break down because it speeds up oxidization. However, some foods have a shorter shelf life than others.
Not only that, vacuum-sealed food may not be as healthy as you think. There are some concerns that the use of vacuum packing, especially with meat and fish, can cause the spread of bacteria. When these foods are sealed in a vacuum environment, it is much harder to destroy any bacteria that may be present.
In fact, vacuum packing can actually increase the levels of bacteria on food. Vacuum packing can also lead to the over-cooking of some foods as it speeds up the Millard reaction (the process that makes the food brown and crispy). This is because, when air is removed from the packaging, there is no way for heat to escape, so the food inside will cook much more.
So, while vacuum-sealing has some benefits, there are also some important disadvantages to be aware of. It’s important to understand these before deciding whether to use this method of food storage.
