Vacuum Barrier’s NITRODOSE® liquid nitrogen injection systems are used to pressurize and/or inert delicate packages, like cans and PET bottles.
The same equipment used for pressurization and inerting can also be used for nitrogenation of beer or coffee, with or without widget. The result is a smooth, creamy product with an attractive cascade effect after pouring.

A precise drop of rapidly expanding liquid nitrogen into hot and cold fill lightweight PET packages and aluminium cans allows for consistent pressure from package to package and eliminates paneling and palletizing problems.
While efforts to reduce the amount of plastic used in each bottle have resulted in more environmentally friendly packaging, these lightweight bottles are less stable. Dosing the headspace of the filled bottles with liquid nitrogen pressurizes the container and adds rigidity, which helps during packaging and handling.
NITRODOSE® systems are also used to inert packaged foods reducing the oxygen absorption by the product to extend shelf life and maintain product taste, color and freshness.
Application in the spotlight: jars of peanuts
Measured amounts of liquid nitrogen evacuate the air in jars of peanuts.

Food Packaging: Is liquid nitrogen dosing a nutty idea?
NITROGENATION OF COFFEE
The addition of Liquid Nitrogen to ready-to-drink coffee products just after filling adds pressure to aluminum cans. This provides the can with some rigidity making it more stable. Liquid Nitrogen dosing can also help reduce O2 in the headspace preserving the flavor and aroma of the coffee.
As cold-brew coffee continues to grow in popularity, more companies are looking to add nitro-coffee to their offering. The same equipment used for pressurization can also be used to nitrogenate coffee to get the smooth, creamy, and attractive cascade effect after pouring, with or without a widget.
NITROGENATION OF BEER
Dissolved oxygen in beer is closely monitored and controlled throughout the brewing process, but O2 pickup can occur during filling. Reducing O2 in the headspace preserves the flavor and aroma of the beer.
Nitro-style beers are a growing segment of the craft brewing industry. The same equipment used to purge the headspace can also be used to nitrogenate a beer to get the smooth, creamy, and attractive cascade effect after pouring, with or without a widget.
