Nitrogen is one of the most popular gases in modified atmosphere packaging. By replacing oxygen in food packaging， nitrogen can significantly extend the shelf life of food - which means less waste and happier customers.

How to extend the shelf life of nitrogen

Modified atmosphere packaging is an important part of food preservation， because it eliminates oxygen and replaces it with nitrogen. As you know， mold and bacteria like mold depend on oxygen for growth. When you remove oxygen， your food will stay on the shelf longer. Nitrogen used for food preservation is also important because it fills every space in the package， so there is no place for water to enter. The modified atmosphere packaging machine allows you to easily replace oxygen with nitrogen on site， greatly reducing waste. Your company saves thousands of dollars every year.

Determination of nitrogen content for food preservation

When determining the nitrogen content for food preservation， there is no universal answer. There are many influencing factors for modified atmosphere packaging， but in general， you need to consider the following five characteristics:

Natural shelf life - compared with shelf-life foods such as honey or dried beans， rapidly deteriorating foods obviously need more nitrogen to preserve the food.

Type of gas mixture - nitrogen is not the only gas used in modified atmosphere packaging. In fact， UNIDO has prepared some recommended gas mixtures for different types of food. Foods with the highest moisture content， such as fresh pasta or pastries， usually use 99-99.9% nitrogen， while others use a mixture of nitrogen and carbon dioxide.

Packaging type - how much material do you use? Is it porous and easily punctured， or is it solid and dense? If there is any possibility of gas escaping， you need to keep this in mind when determining how much nitrogen is required when using the modified atmosphere packaging machine.

Storage conditions - is your product stored on an open shelf or refrigerated or frozen? Foods stored at room temperature usually require more nitrogen.

Advantages of owning a field nitrogen generator (nitrogen generator):

Before using the nitrogen generation system on site, many enterprises in the industry have no choice but to buy nitrogen elsewhere. However, the use of on-site nitrogen generator can eliminate all the troubles related to bulk purchase of nitrogen. Our nitrogen generator is an option with the greatest benefit: the average cost of producing nitrogen by ourselves is one-third to one-half lower than the relevant cost of purchasing nitrogen. Using the on-site nitrogen generator system, there is no need to pay the freight when purchasing nitrogen. Our nitrogen generator system usually allows you to recover the cost within 18 months.

In addition to economy, the nitrogen generator system of the on-site nitrogen generator also provides:

Reliability - the nitrogen generator system, that is, the on-site nitrogen generator system, uses the surrounding air to generate nitrogen. Therefore, our customers never have to worry about the shortage of nitrogen. Reduce stress - improve safety through storage. Simple - we make it easy for people without relevant equipment experience. The visual touch screen control can control the stability of gas purity. At the same time, it can operate self diagnosis, visual operation diagram and maintenance plan reminder on the screen. Flexibility - our equipment is small and can be transported under various conditions, so as long as there is air and electricity, the equipment can operate stably anywhere. Fully automatic - once a downstream request is detected, production begins.

Why use XITE nitrogen generator?   Our nitrogen generator system provides reliable on-site nitrogen supply for various industries, which is famous in China and Southeast Asia. Our on-site nitrogen system can produce nitrogen with purity up to 99.999%. For our nitrogen generator, it can meet the nitrogen production in any place and any complex environment.
