Whenever a person visits a grocery store, they will always find packaged foods that are fresh and ready to eat. What they may not realize is that this is possible due the operation of nitrogen membrane generators that are used in the food industry. The use of this equipment enables companies to accomplish their goal of having products stay fresh long enough so that they can reach stores across the country.
One can tell how fresh a food is by the color, flavor, and aroma of it. If these three factors are not in place, a person will not buy the product because it is not appetizing. Also, one has to be careful of getting sick due to products that are not well preserved for a reasonable amount of time. This can cause companies to lose money and customers to lose faith in the companies if there are no solutions.
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.
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.
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.
