The main goal of any business dealing with food is the maintenance of freshness. This is important because foods of various kinds have to travel long distances and there is also the convenience of packaged products which are used by many around the world. This article will look at how the food industry benefits from Nitrogen Membrane Generators.
In order for a particular food item to remain fresh in a package, the color, aroma, and flavor has to be preserved. Most people expect their food to look as if it has been prepared the same day. They expect it to taste, smell, and look appetizing. If it does not meet these requirements, they will not buy the product.
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.
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.
When this level of purity has been decided, a company can then choose the type of system they will use to package their food item. Membrane technology is one of the systems used to create a certain level of purity which is usually below 98%. This is usually good enough for certain types of foods depending on what the company needs.
The creation of packaged foods means that technology has to be used to create a product that will last. There are different types of processes that can be used to accomplish the goal of providing freshness. However, it is the companies that have to decide which one they will use to suit their needs.
