Minipack Chamber Vacuum SealersIf you need to provide maximum shelf life for vacuum-sealed food, without removing all of the air, you need to use what’s known as an inert gas kit. Minipack, one of the leading manufactures of commercial and industrial vacuum food sealers (found here), offers inert gas flush kits for all their chamber machines. This article will cover what is involved in an inert gas kit and why you may want one for yourself.

Vacuum sealers, out of the box, can be used to remove air from a bag for preservation purposes. Minipack vacuum sealers can remove 99.9% of the air in a bag. For food preservation purposes, this gets the job done. The only problem is that not everyone wants to remove all of the air. Many fruits, vegetables, chips, bread products and other food will be damaged and crushed if all the air is removed. By using an inert gas flush kit, air can still be left in the bag and thus the food itself is not damaged.

Why swap out the air? One of the most damaging gasses you can have in packaged food is oxygen. This is because most food-damaging life forms and bacteria use oxygen. In practice, the removal of that oxygen will eliminate the very gas needed to sustain life. This is done by re-balancing the gasses.

Re-balancing of gasses is most economically done via an inert gas kit. The inert gas kit is used to flush out oxygen (O2). Oxygen makes up about 20.9% of the air we breath. The gas kit creates a modified atmosphere, which is process of moving the 20.9% oxygen content down to 0%. By removing the oxygen, and replacing it with another gas, food shelf life can be dramatically extended.

While the oxygen is removed, it has to be replaced by another gas. One of the most popular inert gasses used is nitrogen (N2). Another inert gas is carbon dioxide (CO2), which helps cut down on bacterial growth while lowering the PH. Carbon monoxide has even been used as an inert gas as it helps red meet retain a bright red color. These gasses are all considered to be safe for use with food. The gas used will ultimately depend on the product being packaged.

As mentioned earlier, Minipack offers an inert gas flush kit for all their machines. That kit must be factory installed, so you will want to request it when purchasing a new machine. The price of the kit varies from one machine to another.
