Nitrogen for food packaging and processing
There are numerous uses of nitrogen for food processing. The liquid form of nitrogen is extremely cold (-196° C) and can be used to freeze food quickly. Rapid freezing of food leads to smaller ice crystals which results in smoother tasting and longer lasting food.
Did you know?
If you have a sweet tooth, you must be interested in knowing that nitrogen is used to put bubbles in chocolate bars like Dairy Milk Bubbly, Nestle Aero, and Roshen Dark Bubble chocolate. The melted chocolate is frothed up with nitrogen and when it cools down, air pockets/bubbles appear in the chocolate. Although gases like argon and carbon dioxide can be used for this purpose nitrogen makes bubbles smaller and imparts a creamier taste making the chocolate more delicious.
Nitrogen for food preservation is the best option available. By replacing oxygen in food packaging, the shelf life of the products can be tremendously increased. N2 has been used in the food packaging industry for a long time as it helps to preserve the integrity, freshness, and quality of the delivered product. Food packaging types include cans, bottles, boxes, bags, and containers (both, plastic and cardboard).
Packaged food manufacturers commonly use nitrogen purging to displace oxygen from the food package before it is finally sealed because the existence of oxygen develops moisture in the package which leads to the deterioration of food quality. Displacing oxygen from food and infusing nitrogen is a safe practice that is used throughout the food industry.
The second major reason for nitrogen being used for food packaging is to produce a pressurized atmosphere in the packed food preventing it from collapsing. Utilizing N2 guarantees that delicate food like wafers, crackers, do not get squashed in the sacs when are stored or transported. The most efficient and well-known way to use nitrogen for food processing and packaging is with a nitrogen generator. MVS Engineering Pvt. Ltd. nitrogen generators are cost-effective, reliable, and the safest alternative to high-pressure N2 cylinders. MVS is a leading manufacturer that designs and builds generators to comply with each customer’s requirements.
