The food industry has always been concerned with the freshness of food since this is how they are able to make a profit. The longer the freshness last, the more places it can be shipped to and the more people these products can reach. This is why many companies employ nitrogen membrane generators to help them fulfill their goals.
Packaged foods are usually carried in food trucks to their destination. When a customer decides to buy a particular food item, they want to be sure that it looks and taste the way it should. Many times a person will not purchase something that does not meet their standard of what quality is or what the companies claim it should be.
As a result, companies have to come up with solutions that will solve the various issues concerning preservation. One of these is oxidation. This occurs when a food is exposed to oxygen, and over a period of time, the color aroma, and flavor of the food changes. A good example of this is an apple that has been cut which turns brown changing the way it taste and looks.
To prevent this from taking place, nitrogen is used to replace as much oxygen as possible in packages. Nitrogen is inert and does not react in any way with the chemicals that naturally occur in food. This is an advantage for companies who need a solution to the problem of maintaining freshness in packaging.
In addition to minimizing bacterial growth, it also helps in preventing rancidity caused by the natural oils found in food. These oils can be found in products like potato chips and other foods that have naturally occurring oils in them. A process known as blanketing coats the food with a layer of the inert gas which helps the product to have a longer shelf life.
The nitrogen used must also be of a quality that is compatible with food. There is an industry standard which suppliers have to comply with in order to be able to use this gas in the packaging of food. The purity level of the nitrogen is also important and depending on the food can range from 95% to 99.9% purity. An oxygen meter is used by companies to measure the minimum amount of oxygen in the package that can remain without spoilage to determine how pure the nitrogen should be.
There are different types of systems that are used to create the purity that is needed. If membrane technology is used, the purity level is less than it would be using a different system. Some companies are satisfied with 98% percent which is what they will get if they use this type of technology. On the other hand, other companies might need a higher number.
Advanced technology have allowed members of the food industry to create products that will not spoil after a short period of time. This is good for those in business because they will be able to serve millions of customers all over the country. However, it is also good for the customer since they will be able to have foods that are convenient to use.
