How Effective is Vacuum Sealing?
Last Updated January, 2020
Vacuum sealing is a process which is used to prevent most of the food items from breaking down when exposed to air. This storage method works well with the dry food items, frozen foods, and even refrigerated food. Some even use it to store other items like jewelry, especially the one made out of silver, since the vacuum would prevent any sort of tarnishing to occur while they are stored away in our closets. However, it is to note that this process should in no way replace the conventional heat locking system used for cans or the refrigeration or freezing of food items.
So, just how how effective is vacuum sealing?
It is one of the most economical and effective methods used to increase the life of the items we intend to store. Especially, if it food then this method helps retain the texture and the taste of the items being stored. Some of the other benefits that the method poses are:
This method has no downside to it except for the fact that the bags are not completely impervious to air. So after a couple of years, the things might start to get damaged since the air would get accumulated in the bag. Also, this method is not effective against the storage of the pointy object. While the vacuum channel creates a vacuum in the bag, the sharp edges can rupture the bag and allow air to enter.
Some people use oxygen absorbents with this process to further increase the life of the things being sealed. In case it is the food, then you might want to freeze it before sealing so the liquid doesn’t crawl out of it to break the seal. Same is applicable for saucy food. Refrigerate it before sealing so that the sauce thickens and loses its liquid form.
Although vacuum sealing works on mostly all kinds of food items but tries to store only the ones that you eat so that the effort and the food are not wasted.
