Liquid Nitrogen (LN2) Dosing

Liquid Nitrogen LN2 Dosing in Food & Beverage, Personal care product packaging: enhancing quality, shelf-life, consumer satisfaction, and environmentally friendly.


Maintaining product quality and extending shelf life are critical objectives in the food, beverage & personal care industry. To achieve these goals, innovative techniques are continuously being developed. One such technique gaining popularity is liquid nitrogen dosing, which involves the controlled injection of liquid nitrogen into product containers during the packaging process.

Liquid nitrogen dosing is considered one of the most significant cryogenic technology adaptation, which not only benefit many industries in their cost reduction and quality improvement in product packaging, but also the environment.

Benefits of Liquid Nitrogen Dosing

Liquid nitrogen dosing offers a wide range of advantages for product packaging. Let’s explore some of the key benefits.

Preservation of Freshness and Taste

By displacing oxygen, liquid nitrogen dosing effectively prevents oxidation and the growth of spoilage microorganisms. This preservation technique helps maintain the freshness, taste, color, and nutritional value of beverages. It is particularly beneficial for oxygen-sensitive products like juices, wines, teas, nuts, flavored health supplements, and carbonated drinks.

Nitrogenation for Beverage Products

Nitrogenation enhances product creaminess and creates a captivating cascading bubble effect during pouring. Nitrogenation also reduce dissolved oxygen content in the product.

Improved Packaging Rigidity

The expansion of liquid nitrogen into gas within the container creates internal pressure, resulting in a firmer and sturdier packaging structure. This increased rigidity enhances the container’s ability to withstand external forces, reducing the risk of damage during transportation and storage.

Mitigation of Vacuum Paneling

Vacuum paneling, a common issue in hot-filled product packaging, can lead to deformation when the vapor inside the container condenses, creating a vacuum paneling effect. LN2 dosing effectively mitigates this risk by introducing liquid nitrogen into the headspace, countering the formation of vacuum and maintaining the integrity of the packaging.

Lightweighting and Sustainability

Liquid nitrogen dosing supports lightweighting efforts in packagingdesign. The internal pressure generated by the expansion of liquid nitrogen allows for the reduction of material thickness while preserving the structural integrity of the container. This approach reduces environmental impact by using fewer raw materials, lowers shipping costs, and contributes to overall sustainability in product packaging. This innovation benefits not only the food and beverage industry but also sectors like personal care, chemicals, and various other products that utilize plastic or metallic packaging materials.
