    Gas Flush Packed Food

    The gas flush packaging machine finds its most common and wide application in the food industry. The reason behind this lies in the fact that the gas flush packaging machine preserves the quality of food during the intended time period.

    As already discussed, the gas flush packaging machine eliminates all the oxygen or any other foreign particle present inside the packaging.

    The oxygen present in the atmosphere actually play a significant role in food spoiling. It can do it in various ways such as oxidation reactions and provision of suitable conditions for microbial growth and contamination.

    These reactions or processes lead to a very off flavor and a foul order of food. The gas flush packaging machine actually saves the food from all this because of its efficient operation.

    Many different kinds of food products such as sea food, poultry items, meat and cheese are packed using the gas flush packaging machine.

    The Pharmaceutical Industry

    Gas Flush Packaging

    The gas flush packaging machine is also used in the pharmaceutical industry for packaging the drug products that are prone to damage due to atmospheric oxygen, moisture or microbial contamination.

    The environmental damage to the drug can reduce its efficacy to such a low level that it fails to achieve minimum effective concentration in the blood. The contaminated drug also has an increased toxicity which can lead to severe side effects.

    The gas flush packaging machine saves the drug product from any damage during the intended shelf life. In this way, the efficacy and effectiveness of the drug product is conserved throughout the shelf life.

    5.How the gas flush packaging machine works?

    gas flush packaging machine works

    The gas flush packaging machine is a very simple machine and its working is not too complicated. It does an amazing job by following just a few simple steps.

    First step in the working of the gas flush packaging machine is flushing off the gases (especially oxygen) present inside the package. For this purpose, of gas such as nitrogen or carbon dioxide is frequently injected in and evacuated out of the package many times.

    The density of the gas used for flushing is usually greater than oxygen. This causes the forceful elimination of oxygen from the package. This step reduces the oxygen concentration inside the package to a significantly low level.

    The second step involves the vacuum packaging. The gas flush packaging machine creates a vacuum inside the package and then the package is sealed.

    Vacuum sealing ensures prolonged quality preservation of the products by reducing the chances of microbial growth.

    These two steps briefly explain the working of the gas flush packaging machine.

    6.Which kinds of gases are used in gas flush packaging machine?


    The working of the gas flush packaging machine greatly depends upon the type of gas you are using for flushing purpose. Choosing the right gas for your intended purpose is a very crucial step. Different types of gases used in the gas flush packaging machine are discussed below.


    Being a non-reactive and an inert gas, nitrogen is used in the gas flush packaging machine for eliminating the air from the package. Oxygen is the main target of nitrogen.

    Nitrogen also finds its application as a filler gas for prevention of the collapse that may be caused in the packaging of the products which tends to absorb carbon dioxide.

    Nitrogen (100%) is also used for preventing the oxidative rancidity in the packaging of the dry snacks.

    Carbon dioxide

    Carbon dioxide is the most efficient gas for inhibiting the microbial growth. Therefore, using carbon dioxide for flushing purpose can be very beneficial.

    Generally, the greater the concentration of carbon dioxide used, the greater is the preservation of products inside the package. But the level of carbon dioxide must not exceed limit because it can lead to package collapse, tainting of flavor and drip loss.

    The lower limit of the concentration must also be considered. For example, minimum concentration of carbon dioxide for controlling the growth of molds and bacteria must be greater than 20%. Any concentration below 20% will not do the job effectively.


    Visual look of Aragon gas

    Visual look of Aragon gas

    The properties of argon are same as nitrogen. Argon is non-reactive, odorless, tasteless and an inert gas. The molecular weight of argon is greater than that of nitrogen.

    Argon can replace nitrogen in the controlled atmosphere in various applications because of its similarity with nitrogen but a greater weight.

    The solubility of argon is twice as compared to that of nitrogen. These factors make argon a preferred gas for usage with the plant products.

    It is believed that argon inhibits microbial growth, harmful chemical reactions and enzymatic activities.


    Surprisingly, oxygen is also sometimes used as a MAP gas. Although oxygen has destructive reactions with food that cause its spoiling but in some cases, oxygen may prove to be beneficial.

    For example, oxygen can inhibit microbial growth in some vegetables and fruits. It can also maintain respiration in plant products and freshness in meat.

    Carbon Monoxide



    Carbon monoxide is harmful, flammable, colorless, odorless and a toxic gas. Carbon monoxide is also used in gas flushing along with carbon dioxide for increased shelf life and preservation of red meat.

    The properties of carbon monoxide that make it a worthy candidate for its use in gas flushing include its stability at higher temperature and its ability to inhibit the growth of many harmful bacteria

    9.Which gas is suitable to use in a gas flush packaging machine to keep the food fresh?

    keep the food fresh

    The best gas to use in a gas flush packaging machine to keep food fresh is carbon dioxide (CO2). Carbon dioxide is an inert, non-toxic gas that helps prevent the growth of bacteria and microorganisms, as well as slowing down spoilage.

    Carbon dioxide is also used in modified atmosphere packaging (MAP) systems, where it is combined with other gases like nitrogen or oxygen to create an optimum environment for preserving food. Additionally, CO2 is also used for carbonation and freezing applications.

    It has a low vapor pressure, which helps it penetrate deep into the package, thereby creating a tight seal. It is also easy to transport and handle, making it an ideal choice for gas-flushing packaging systems.

    Aside from CO2, other gases that can be used for gas flush packaging include nitrogen (N2), oxygen (O2), argon (Ar), and hydrogen (H2). However, these gases may be less effective than CO2 in preserving food quality and shelf life.
