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.
To make sure that the customer is satisfied, the companies make use of various processes in order to create the best environment for the quality of the food to be maintained. To do this, there has to be a way to prevent oxygen from interacting with the natural chemicals found in food. This interaction is known as oxidation, which can be seen when cut fruits like apples turn brown.
This is one of the reasons why nitrogen is used in the packaging of food. It does not change the color, flavor or aroma of the food the way oxygen would. It also helps to minimize the bacterial growth that easily occurs in food. This is due to the fact that nitrogen is an inert gas and will not react with other chemicals in edible products.
Oxidation does not only affect the color of the food in question, but it also interacts with natural oils creating rancidity. To prevent this process from taking place, nitrogen blanketing is used to stop the process of rancidity which helps to maintain the freshness of the product. Items with naturally occurring oils in them include chips and other snack foods that have a significant amount of oil.
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.
