What Do We Use Nitrogen For? The 5 Major Uses Of Nitrogen In Everyday Life

Nitrogen gas makes up approximately 78 percent of our atmosphere, which makes it one of the most common gases on Earth. Nitrogen is non-toxic and inert, so it’s a safe gas to include in industrial processes.

If you’re wondering “What do we use nitrogen for?” the answer is, a lot!

The prevalence of nitrogen in our atmosphere combined with its inert properties makes it a very useful gas for food packaging, pharmaceuticals, and other industries. The use of nitrogen can prevent oxidation, corrosion, and deterioration of materials like foods and medicines. In this article, we’ll go over the uses of nitrogen and how it’s beneficial to industrial processes.

5 Major Uses of N2 in Everyday Life

Do you need a nitrogen generator? You probably do if you’re involved in one of the following industries. If you do need an N2 generator, whether that’s a PSA nitrogen generator or a membrane nitrogen generator, contact On Site Gas Systems to get started.

Food Packaging & Preservation

Nitrogen gas has transformed the food packaging industry. Exposure to oxygen shortens food shelf life by causing oxidation, leading to a change in food quality, flavor, smell, and color. By packaging food in a nitrogen-rich environment, food manufacturers can limit food’s exposure to oxygen and thus prevent food from deteriorating in the packaging.

Packaging with nitrogen is often done with a nitrogen flush technique, meaning that the oxygen and other gases in the packaging are flushed out with nitrogen. The nitrogen is sealed in the package, creating a protective bubble around the food and preventing it from breaking in transport.

Electronics

Nitrogen’s inert properties have an advantage over oxygen in electronics soldering. The use of oxygen in electronics soldering can cause oxidation in the immediate area being soldered, but nitrogen does not.

Oxidation is detrimental to soldering tools, circuit boards, and component leads. Oxidation is the rusting process that causes deterioration of many metals. The use of nitrogen in electronics soldering leads to a more durable electronics product and helps preserve the soldering tools used as well.

Pharmaceuticals

Just as nitrogen is used in food packaging to prevent oxidation of foods, nitrogen is also used in pharmaceutical packaging to prevent oxidation of medications. This helps preserve medication quality and integrity and leads to a longer shelf life. The use of nitrogen in packaging also makes for easier transportation and allows medications to be transported all over the world, because of the way nitrogen extends medication shelf life.

Beer/Beverage

In the beer and brewing industries, nitrogen is used to purge tanks to prevent drink spoilage. Nitrogen use in beer has also been attributed to better flavor as well as longer shelf life. Nitrogen is used to create the “fizz” in beer and is sometimes favored over CO2 because it is less likely to cause unwanted chemical reactions.

Tire Inflation

Nitrogen gas is an important tire filler. Not everyone who drives a car needs nitrogen-filled tires, but some prefer it. The reason that nitrogen is slightly better for filling tires than normal air is that nitrogen molecules are larger than oxygen molecules. Tires are porous, and sometimes temperature changes can force oxygen out of the tires via the pores.

This very slow leak can result in minute changes in tire pressure over time. Since nitrogen molecules are larger, the leak produced by nitrogen tires is much slower, leading to more consistent tire pressure over time.

Nitrogen Purging Systems: What They Are & How They Work

Nitrogen purging is an important industrial process that impacts many industries, from brewing to shipping. If your business requires nitrogen purging systems, knowing what they are and what the process looks like can help you determine if it’s needed at your plant or business.

If you need to set up a nitrogen purge system, it’s important to buy from a reputable company, like On Site Gas Systems, that creates high-quality products.

What Is Nitrogen Purging?

Nitrogen purging is a process that removes the environment of unwanted gasses using nitrogen. As an inert gas, nitrogen can be used to displace other gasses without setting off a chemical reaction. During nitrogen purging, nitrogen may be used to displace oxygen and other gasses that contribute to oxidation.

There are many reasons for purging with nitrogen, but the most obvious benefit is the removal of gasses that lead to the chemical alteration of products. Purging with nitrogen can prevent moisture-related damage to equipment and products.

How Does Nitrogen Purging Work?

There are four ways to purge with nitrogen:

Pressure-hold vacuum method. The pressure-hold vacuum method involves pressurizing a vessel using nitrogen. When the contents of the vessel are combined with nitrogen, the original gas becomes diluted. The combination of gasses is vented and then the vessel is re-pressurized with nitrogen. This process is repeated as many times as necessary until the contents of the vessel have an acceptable level of nitrogen. This works on vessels with only one opening.

Pressure transfer of liquids. Pressurizing the headspace within a vessel allows for the transfer of liquids without a pump. Doing this significantly reduces the risk of oxidation, which can occur while transferring liquid from one tank to another.

Displacement purging. This process works in pipelines and in vessels shaped like pipes. The process works when a scraping piston, called the “pig” is propelled by the nitrogen pressure. The pig pushes through the line and purges the line of contents that are not nitrogen. Sometimes, the pig is replaced with an inert fluid.

Dilution purging. Dilution purging works by mixing nitrogen with the gas to be purged. This works in vessels with two openings. The nitrogen gas is pushed into the vessel and mixed with the other gas in the vessel and then is effectively purged through the outlet.

When deciding which type of nitrogen purging is right for your industrial process, it’s important to consider factors like the vessel’s shape and how many inlets and outlets are available. No matter what method you choose, you’ll need a steady supply of nitrogen to make this process work. For this, you’ll need a nitrogen generator.

Nitrogen generators come in different types and can produce different levels of purity. On Site Gas Systems makes PSA (pressure swing adsorption) generators and membrane nitrogen generators for businesses that need a steady supply of nitrogen for their manufacturing and other processes. We also make custom generators to ensure that businesses can find the right type of generator no matter what their needs. To find out which type of nitrogen generator is right for your business, contact On Site Gas Systems.

How Nitrogen Flush Packaging Machines Prevent Food Spoilage

If you’re in the food packaging industry, you know how important it is to ensure that your food stays fresh for as long as possible. For many kinds of food, just how fresh the food stays depends on the packaging.

The right type of packaging can help your food stay fresh for a long time, and for many types of food, nitrogen flush packaging is the right type of packaging. Knowing how nitrogen flush works, why it helps extend the shelf life of your foods, and what you can do to use this type of packaging in your business is important. Here’s what you should know.

What is Nitrogen Flushing in Food Packaging?

Nitrogen flushing is the process of flushing out the air in a package to replace it with nitrogen. First, the food is inserted into the packaging. Next, the package is flushed with nitrogen. The nitrogen displaces the air in the package while drying out unwanted moisture in the packaging. Finally, the package itself is sealed up.

This process is used in the packaging of many different types of food, including potato chips. Nitrogen takes up space in the bag and keeps the bag puffed up when it’s sealed. This puffiness gives the chips a cushion and prevents the chips from becoming crushed during transportation.

Why Is Nitrogen Gas Used in Packaging?

Nitrogen gas is used in packaging because:

  1. It’s easy to access (it is in the air all around us)
  2. It’s inert
  3. It’s non-toxic
  4. It helps to prevent spoilage

All of these qualities make nitrogen a relatively easy gas to use for food packaging. It’s also very effective.

Nitrogen does not react with the food in the package, so it stops the food from deteriorating over time. Food that has been stored in nitrogen-rich packaging can retain its flavors and colors for much longer than it would if it had been stored in an environment that contained oxygen.

How to Produce Nitrogen for Food Packaging

The most efficient way to produce nitrogen for food packaging is with an On Site Gas Systems nitrogen generator. Nitrogen generators pull the nitrogen from the surrounding air, filter out the oxygen and other particles in the air, and then expel a steady supply of nitrogen to use for nitrogen flushing.

What Are the Benefits of Using Nitrogen Gas in Packaging?

There are many benefits of using a nitrogen flush packaging machine for your food packaging business.

Safe

Nitrogen gas is a non-toxic gas, so it’s safe to work with, and safe to use in food packaging for humans.

Displaces Oxygen

In food packaging, nitrogen helps reduce the amount of oxygen present, which can promote the growth of harmful microorganisms in the food. Oxygen also accelerates the deterioration of food, altering its flavor and color. By using nitrogen packaging, a low-oxygen environment is created, slowing down these negative effects.

Non-Reactive

Nitrogen is an inert gas, which means that it will not react with the food in the packaging. Whereas oxygen causes these off flavors and can change the appearance of the food over time, nitrogen cannot.

Abundant

Nitrogen makes up approximately 78% of the Earth’s atmosphere. This abundance helps make harnessing nitrogen in the air relatively easy. With a relatively low-cost nitrogen generator system, food packaging companies can use the nitrogen that’s present all the time to keep food fresh.

Nitrogen Gas: A Packaging Gas That Keeps Your Snacks Fresh & Last Longer

Most consumers don’t realize it, but food packaging companies rely on nitrogen to keep their food fresh. Nitrogen is a convenient, plentiful gas that’s all around us, and when it surrounds food, that food can stay fresh for longer periods.

N2 packaging allows food to be stored for a long time. With this type of packaging, food can be transported to locations all around the world for commercial purposes.

If you’re a consumer, you probably interact with nitrogen packaging all the time. If you represent a food packaging business, nitrogen gas for packaging is one of your best tools for keeping food fresh. Here’s what to know about nitrogen packaging processes.

What Is Nitrogen Packaging?

Nitrogen packaging involves filling a package with nitrogen and then sealing it to ensure the nitrogen remains trapped inside. This technique, prevalent in the food and pharmaceutical sectors, serves to maintain the freshness of the package’s contents. The nitrogen acts as a preservative, displacing oxygen which can cause spoilage. As a result, products last longer, retain their flavors, and stay free from undesirable contaminants.

Why Nitrogen Is Used in Food Packaging & How Does N2 Keep Snacks Fresh?

Nitrogen, a non-reactive gas that naturally exists in the air we breathe, plays a pivotal role in food packaging. Extracting nitrogen from the atmosphere is both straightforward and cost-effective. When introduced into food packaging, nitrogen remains inert, meaning it doesn’t interact with the food. This unique property helps prolong the freshness of the food, preventing the rapid deterioration often caused by oxygen-rich environments.

How to Make Nitrogen Packaging Happen In Your Business

There are many ways to get a steady supply of nitrogen in your food packaging process. By utilizing a reliable On Site Gas Systems nitrogen generator, your business can get the nitrogen it needs to keep operating.

However, not all methods of nitrogen acquisition are created equal. Nitrogen cylinders, for example, have more disadvantages than generators. These cons should be considered before making the decision to rent cylinders. Remember, choosing the right source of nitrogen is important for the long-term success of your business.

Cylinder Rental

Nitrogen cylinder rental is a common method that businesses use to get the steady supply of nitrogen they need. However, renting your nitrogen in cylinders or another type of container creates an ongoing cost. If your business is heavily dependent upon nitrogen, cylinder rentals can become inefficient and expensive.

On Site Generator

Nitrogen generator systems are an efficient and effective way to remove nitrogen from the air and use it in packaging. Nitrogen generators come in two types: membrane nitrogen generators and pressure swing adsorption generators (PSA). The differences between these two types of generators give businesses flexibility when choosing the generator for their needs.

Once the generator is purchased, there are few ongoing costs. Maintenance needs for both of these system types are relatively low, and the same goes for utility costs. These systems produce a steady, dependable supply of nitrogen without incurring the ongoing costs that nitrogen cylinders represent.

How To Prepare Your Business For An Onsite N2 Generator (What To Consider)

If your business is nitrogen dependent, then a nitrogen gas generator may be the right piece of equipment for your industrial processes. Nitrogen gas generators are an essential tool for businesses in pharmaceuticals, food processing, metallurgy, aerospace, and more. If your business has a need for nitrogen and is currently dependent upon nitrogen cylinders or liquid nitrogen you could be losing money on monthly expenses relating to nitrogen deliveries.

Purchasing a nitrogen generator system can help your business save money while also ensuring that your business will have the continuous supply of nitrogen that it needs to keep functioning. Before installing a nitrogen generator, it’s important to understand the many ways your business must prepare for this type of installation.

Why Get An N2 Gas Generator Installed?

Does your business need a nitrogen generation system? Below are some of the benefits of nitrogen generator installation:

  • Generators offer a continuous supply of nitrogen provided at a minimal monthly expense
  • Nitrogen generators need little monthly maintenance to function
  • Nitrogen generators are far more efficient and eco-friendly than nitrogen cylinders
  • Your business can save money on regular nitrogen costs with a generator

What To Consider Before Installing a Nitrogen Generator System

Before installing a nitrogen generator in your business, there are many notable factors. Here’s what to know about when trying to decide if a nitrogen generator is right for your business:

Do You Have the Space?

Nitrogen generators don’t have to be very large. In fact, membrane nitrogen generators, with no moving parts, have a relatively small footprint and can easily be used for mobile applications. The size required for a generator depends on how much nitrogen gas is needed for your process. Still, even businesses that need a lot of nitrogen can get by with a relatively small nitrogen generator. If you’re not sure what size generator is right for your needs, speak with the experts at On Site Gas Systems.

Infrastructure Considerations

Because nitrogen generators extract nitrogen from the air in the environment, your nitrogen generator will need piping from your compressed air supply. Your business may already have this type of piping network in place for your industrial processes. If this is the case, you may not need to make changes to your facility. However, if your facility does not have this piping in place, you’ll need to get it in place before the generator can be run on site. Work with your generator manufacturer to ensure that the piping that you’ve installed is adequate for your nitrogen generator.

Power Source

Your nitrogen generator will need a power supply. Nitrogen generators only require a minimum of power. Usually, no more power than it takes to run a desktop computer.

Ventilation Requirements

Ventilation is required for the space around the nitrogen generator. The nitrogen generator will expel waste (mainly in the form of low-concentrated oxygen) that should be ventilated from the space. Under normal conditions, the area where the nitrogen generator is located will have natural ventilation, and no changes are needed.

The Differences Between PSA N2 Generators vs. Membrane N2 Generator Technology

If your business relies on nitrogen for its industrial processes, you may need an onsite nitrogen generator to produce the quantities of nitrogen you need on an ongoing basis. It takes only a little bit of searching online to discover that there are multiple types of nitrogen generators, including pressure swing adsorption (PSA) nitrogen generators and membrane nitrogen generators.

These two types of generators function very differently. Each has specific benefits that make them important for different industries and types of businesses. If you need help determining which type of nitrogen generator is right for you, it helps to get assistance from the experts here at On Site Gas. At On Site Gas, we can help you decide which type of nitrogen generator is best for your business.

Here, we’ll discuss the differences between PSA and membrane nitrogen generators, covering everything you need to know.

What Is a PSA N2 Generator?

PSA nitrogen generators are the preferred type of generator for businesses that need high-purity nitrogen gas. High-purity gas is gas with a purity level of approximately 99.9995%. This purity level is often required in electronics manufacturing, chemical and petroleum industries, and metallurgy.

What Is a Membrane N2 Generator?

A membrane nitrogen generator uses a membrane to separate nitrogen from other elements in the air. Membrane nitrogen generators produce nitrogen at a purity level between 95 and 99.9%. This purity level makes membrane nitrogen generators a perfect choice for manufacturers in the food and beverage industry as well as the automotive and aerospace industries.

What Are The Differences Between PSA and Membrane Nitrogen Generator Technology?

PSA and membrane nitrogen generators each produce nitrogen, but they work very differently. Here’s how:

How Does a Nitrogen PSA Generator Work?

PSA generators pull air into a tank that contains a carbon molecular sieve (also called a CMS). The generator then increases pressure in the tank, and the CMS absorbs oxygen and other non-nitrogen particles. Once this is done, a high-purity stream of nitrogen is produced.

PSA generators usually have two tanks that work in tandem, so while one tank is filling and producing nitrogen, the other tank can clean out the CMS material. Then, the tanks switch roles. This repeats over and over again as the PSA nitrogen generator works.

Benefits of a PSA Generator

  • Low maintenance. PSA generators are generally low-maintenance. These generators require periodic filter changes but can otherwise last for many years without any needed repairs or other types of maintenance. With this level of care, PSA generators can last for two decades or more.
  • Consistent production of nitrogen. Even as they age, PSA generators continue to produce nitrogen at the same purity level. This makes PSA generators a good investment for businesses that need high levels of nitrogen.

How Does a Nitrogen Membrane Generator Work?

Membrane nitrogen generators work by pushing air through a cylindrical tube that contains a nitrogen generator membrane fibers. As the gas enters the membrane, the unwanted elements in the air (oxygen, for example) are directed to an exhaust vent, while the nitrogen gas exits at the outlet portion of the tube.

This produces a continuous flow of nitrogen gas. There are no moving parts for this type of generator, and that can be very helpful for processes that are sensitive to vibrations.

Benefits of a Membrane Generator

  • Simplicity of design. Membrane generators have no moving parts, which means that they’re especially easy to maintain. This also ensures a continuous supply of nitrogen.
  • Easy to store. Membrane generators are compact, so they’re easy to store in small spaces and can be configured for mobility as well.
  • Long-lasting and durable. Because they have few or no moving parts, membrane generators are easy to maintain and last for a long time.

Still Not Sure Which Generator To Buy? Call On Site Gas

The professionals at On Site Gas are available to help you decide which type of nitrogen generator is right for you. In addition, we design custom generators for our clients. Call for a consultation, and we can design the best nitrogen generator for your needs.

Choosing the Right PSA Nitrogen Gas Generator for Your Specific Application

Nitrogen gas is an in-demand product used in a variety of industries, from food packaging to steel production. In many industries, nitrogen is used to prevent products from spoiling, thus allowing food and medications to be stored longer and transported long distances. This makes nitrogen very important to our global supply chain, and an important material for many companies. Nitrogen is present in the air we breathe, but capturing nitrogen for use in manufacturing industries requires special equipment.

If you’re a business that uses nitrogen in its day-to-day manufacturing, it’s important to find the right type of nitrogen generator for your business. The best generators will efficiently produce enough nitrogen for your needs, at the purity level that you require.

Unlike cylinders or liquid nitrogen, PSA nitrogen generators are cost-effective and relatively low-maintenance. There are many benefits of quality nitrogen generators. Here’s what you need to know.

What Is a PSA Nitrogen Generator?

PSA stands for pressure swing adsorption. A PSA nitrogen generator is a device that produces nitrogen through a process that starts when compressed air is filtered to move impurities like oil and moisture. Once the air has been filtered in this way, it is passed to adsorption vessels with a special sieve that can adsorb any remaining carbon dioxide, moisture, and oxygen. Once this is done, the filtered nitrogen is produced at the desired purity, while any remaining oxygen is vented back into the atmosphere.

What Is a Membrane Nitrogen Generator?

A membrane nitrogen generator works by pushing compressed air through polymer fibers. As the compressed air moves through the fibers, the nitrogen molecules are separated from the other molecules in the air. Through this process, nitrogen is produced at the desired purity. While any remaining oxygen is vented back into the atmosphere.

PSA vs. Membrane

PSA and Membrane nitrogen generators are both similar but very different devices, so it’s important to understand those differences when trying to determine which type of generator is right for your business.

PSA Generator Purity Levels

Nitrogen purity is an important factor when trying to choose between two different types of generators. PSA nitrogen generators can provide nitrogen at a higher purity than membrane nitrogen generators. In fact, PSA generators from On Site Gas can produce nitrogen at a purity level of up to 99.9995%, depending on your needs. Knowing the purity level that’s required for your manufacturing process is important when trying to decide which type of generator is right for you, so have this information before you start shopping for a generator manufacturer.

PSA Generator Consistency

PSA nitrogen generators can reliably produce the nitrogen gas at the high purity level required. In industries where a consistent high purity level is required, PSA generators are the best product.

PSA Generator Durability and Maintenance

PSA nitrogen generators have few moving parts, so they’re long-lasting and require little maintenance. Many of On Site Gas’s PSA nitrogen generators last for twenty years or more before needing replacement. The sieve material that is used in the PSA process can last for decades with minimum maintenance.
Membrane Generator Purity Levels

Membrane generators from On Site Gas can produce nitrogen with a purity level between 95% and 99.9%. Talk to your representative from On Site Gas to tell them the purity level that you require.

Membrane Generator Durability and Longevity

Membrane generators have no moving parts, which makes them easy to maintain and easy to repair if needed. Membrane generators made from On Site Gas last for many years.

Why PSA or Membrane Nitrogen Generators?

PSA or Membrane nitrogen generators from On Site Gas are preferred by many businesses for nitrogen delivery. There are many reasons for this, including energy savings, cost savings, safety, and versatility.

Energy savings. On Site Gas PSA or Membrane nitrogen generators go into standby mode when not in use, as pressure monitors within the system continue to create just enough pressure to ensure nitrogen generation is quick and efficient when nitrogen generation begins.

Cost savings. PSA or Membrane nitrogen generators are a budget-friendly option for businesses that need an affordable supply of nitrogen. PSA or Membrane nitrogen generators are much more affordable than cylinder delivery or liquid delivery of nitrogen.

Safety. Nitrogen generators are safer than high-pressure cylinders full of gaseous nitrogen, and cryogenic liquids full of very cold nitrogen. Nitrogen generators are stable, easy to use, and produce a steady supply of nitrogen when needed.

Versatility. PSA or Membrane nitrogen generators are highly versatile and can be used for applications across industries ranging from electronic manufacturing to food packaging to laser cutting. On Site Gas has created nitrogen generators that provide the quantity, purity, and flow of nitrogen that you require.

How Do Onsite Nitrogen Generators Work?

Nitrogen is a crucial element that makes up a significant portion of the air we breathe. It is an inert, non-toxic gas with a wide range of industrial applications, from preserving food to facilitating steel production. For businesses requiring a consistent supply of nitrogen, onsite nitrogen generators offer a cost-effective and reliable solution. But how do these generators produce nitrogen? Let’s dive into the mechanics.

Methods of Nitrogen Production

Onsite nitrogen generators employ various technologies to produce nitrogen gas tailored to specific industrial needs. Whether you’re looking for high purity levels or have budget constraints, there’s likely a nitrogen generator that fits your requirements. Here are some common types:

PSA Nitrogen Generator

PSA, or Pressure Swing Adsorption, is a popular method for nitrogen generation. In this system, air is drawn into the unit and passed through carbon molecular sieve (CMS). This sieve material has microscopic pores that trap oxygen, moisture, and other impurities, allowing only nitrogen to pass through. The system alternates between two chambers to ensure continuous operation.

Advantages:

  • Continuous Operation: Can run 24/7 to meet your nitrogen needs.
  • High Purity: Capable of producing nitrogen with up to 99.9995% purity.
  • Cost-Effective: Operating costs are significantly lower compared to renting nitrogen cylinders.

Membrane Nitrogen Generator

In a membrane generator, compressed air is forced through a bundle of hollow fibers. These fibers selectively permit nitrogen to pass through while filtering out oxygen and other contaminants. The purity level can be adjusted by manipulating the airflow.

Advantages:

  • Continuous Operation: Can run 24/7 to meet your nitrogen needs.
  • Purity Flexibility: Can achieve up to 99.9% nitrogen purity.
  • Low Maintenance: Simple design with few moving parts.
  • Available on demand when your operation needs it, no need to wait for deliveries.
  • Cost-Effective: Operating costs are significantly lower compared to renting nitrogen cylinders.

Custom Generators Available

On Site Gas creates custom generators for businesses, to meet the unique needs of our clients. If a custom generator is needed for your business, we can assess your needs and help you select the right design. Our custom-engineered systems are designed to be an ideal fit for your industry and production environment. We’ll design your generator to meet your unique needs, and provide training.

Refurbished Generators Available

Not every business needs a custom-built nitrogen generator for their business. In fact, some of our clients prefer a refurbished system. These generators have been used by previous clients and have since been completely restored. We fix up generators at On Site Gas to ensure that each refurbished generator we sell meets our most stringent requirements. When you purchase a refurbished generator, you can be sure that your generator will be in good condition and ready to operate for years to come.

Why a Generator Instead Of Nitrogen Cylinder Delivery?

Nitrogen cylinders are commonly used by businesses that only need a small amount of nitrogen, or only need nitrogen occasionally. Cylinders are effective but have many logistical problems, including:

Safety issues. Nitrogen is under high pressure when it’s in a cylinder, which can come with safety risks. Every person who uses these cylinders needs to be taught how to use them safely to avoid accidents.

Space consuming. Depending on how much nitrogen your business requires, and how much nitrogen you order at a time, nitrogen cylinders can take up a lot of space in your facility.

Some nitrogen is always wasted. Some nitrogen is always wasted when you’re using nitrogen from cylinders. Once the nitrogen reaches a certain quantity in the cylinder, the cylinders must be returned to be refilled.

Cost-inefficient. Nitrogen cylinders may be affordable for a one-time only rental, but consider the cost of renting cylinders on an ongoing basis, for many years. Over time, nitrogen cylinders can cost your business far more money than the one-time cost of purchasing a nitrogen generator.

Administrative costs. In addition to the costs of renting nitrogen cylinders, many administrative costs and inconveniences can come from cylinder rental. Supply chain problems can dramatically impact the availability of nitrogen cylinders when they’re needed. Searching for a new nitrogen producer/supplier could waste time and cost your business money.

What Are The Benefits of Modified Atmospheric Packaging (MAP)?

Most foods spoil quickly when they’re exposed to oxygen. The challenge of the food packaging industry is to minimize food contact with oxygen, preventing the food from deteriorating so quickly. This is the basis of modified atmosphere packaging (MAP): by reducing or eliminating food exposure to oxygen, modern packaging helps food last for as long as possible.

There are many benefits of MAP. If you’re in the food industry, it’s important to understand how MAP works and how MAP can benefit your business.

What is Modified Atmospheric Packaging?

Modified atmosphere packaging is food packaging with a controlled environment inside. By reducing the oxygen levels in the packaging, the food’s freshness and quality are preserved for a much longer period.

How does oxygen cause food to spoil? Oxygen:

  • Produces lipid oxidation reactions
  • Causes high respiration rates in fruit and vegetables
  • Promotes growth of microorganisms

Reducing oxygen in the packaging thus delays the reactions that lead to spoilage. The MAP process reduces the oxygen in packaging for exactly that purpose.

What Are The Benefits of MAP?

There are many benefits of using MAP for food items. For example:

  • Long shelf life. MAP allows food to last far longer in its packaging than would otherwise be possible.
  • Packaged products look better. By preventing the food from spoiling or changing while on the shelf, MAP also prevents food from losing its aesthetic appeal.
  • Food retains its nutrients. When food begins to degrade, it can lose its nutritional value. MAP prevents this from happening and thus helps the food stay nutritionally beneficial.
  • Food tastes better. Just as MAP helps food retain its nutritional value, MAP also prevents food from developing off flavors that can ruin the eating experience.
  • Eliminates the need for chemical additives. Chemicals can be used to ensure that food stays fresh, but with MAP, that’s not necessary.
  • Reduces food waste. Food packaged in MAP lasts so long that it’s more likely to be used before it goes bad.
  • Wider distribution range. MAP allows food to be sold in a wider geographic market because the food can tolerate longer shipping times.

Who Needs MAP?

MAP can be used for producers of different food groups. From meats to fruits and vegetables, MAP is helpful for consumable goods. If your business sells pre-packaged food, there’s a good chance that MAP is the appropriate type of packaging for your food product.

How Does MAP Work?

Modified atmosphere packaging works by using a MAP machine to seal food inside a package with a mixture of gasses that can slow down the rate of oxidation and growth of microorganisms. This stops food spoilage and ensures a longer shelf life for the food. The type of atmosphere inside the packaging can vary, but generally speaking, the gasses used in MAP include carbon dioxide, oxygen, and nitrogen.

Two Types of MAP

There are two types of MAP: passive-modified atmosphere packaging and active-modified atmosphere packaging. In active MAP, food is stored in a package that contains the specific mixture of gasses needed for safe storage. In passive MAP, the food product is sealed in a permeable package that allows the correct atmosphere within the package to develop gradually.

Fulfill Your Nitrogen Needs With A Nitrogen Generator

If your business has a consistent need for nitrogen for your modified atmosphere packaging machines, you have options. Some businesses purchase their nitrogen in containers like cylinders or dewars. Cylinder rental may seem like an economic option when you’re considering the cost of a one-time cylinder rental, but those costs can add up if you need to rent cylinders on a regular basis.

Save money and hassle with a nitrogen generator. A nitrogen generator may cost more upfront, but after this one-time purchase is made, the cost to run a nitrogen generator is far less than a cylinder rental. Over many years, your business can save hundreds or thousands on nitrogen.
