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.
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.
Since oxygen creates this situation, which is not good for the food industry, nitrogen is used to preserve edible items in packages. This inert gas does not change the color or flavor of the food and the aroma remains the same for a significantly longer period of time. Bacterial growth is also minimized to a great degree.
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.
Purity levels of nitrogen used in the packaging of food depend on what the company needs to maintain a proper shelf life of the product. This can range anywhere from 95 - 99.9% purity depending on the type of food that is being packaged. Most companies will use an oxygen meter to determine how much oxygen can remain in the packaged product before it begins to spoil or become rancid.
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.
By having their products up to standard, companies in the food industry can provide the best service to their customers. Their products can be taken over long distances of several miles and the quality will remain the same. As a result, the customer can have convenience items that they can take with them on the go, knowing that they will last for a specific amount of time.
