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.
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.
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.
Another issue with food and maintaining freshness is the natural oils contained in the products which can cause rancidity. This is also solved using nitrogen since it is inert and does not cause a reaction with other chemicals inside the food. This gas is used to blanket the product which prevents the oils from being oxidized. The oxygen levels found in the food have to be kept very low for this to take place.
An inert gas like nitrogen, cannot be used just as they are. They have to be food grade and must have a certain level of purity depending on the type of food that is being packaged. The purity level of the gas can begin at 95% and go up to a level of 99.9%. Most companies use an oxygen meter to help them decide on the level of purity they need.
When membrane technology is used to generate nitrogen, the purity level of it is usually less than 98%. This might be good enough for certain companies that manufacture certain types of foods, but it might not be good for others. In this case, another system is usually used if a higher percentage of purity is needed.
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.
