Use of OXYVITAL PSA Nitrogen Generators in Modified Atmosphere Packaging (MAP) Systems
Modified Atmosphere Packaging (MAP) is a technology that packages food products in specially formulated gas mixtures to extend shelf life, preserve freshness, and inhibit microbial growth.
OXYVITAL PSA nitrogen generators bring the oxygen level inside the package under control, creating an inert atmosphere that prevents spoilage. This preserves the quality of oxidation-sensitive food products and helps them stay fresh for longer.

Process-Compatible Integration
On-Site Production Advantage
Why Should You Use a Nitrogen Generator in Modified Atmosphere Packaging?
Provides Precise Oxygen Control
In MAP applications, the key factor determining product shelf life is the oxygen level inside the package. High oxygen accelerates oxidation, leading to discoloration and loss of flavor. PSA nitrogen generators keep the oxygen level within the desired range, bringing this process under control.
Limits Microbial Growth
Lowering the oxygen level slows the proliferation of aerobic microorganisms. This delays spoilage particularly in meat, dairy products, and ready meals, resulting in a safer, more stable product.
Enables Product-Specific Gas Adjustment
Every food product requires a different gas composition. With PSA systems, the nitrogen ratio can be precisely adjusted, providing optimal protective conditions for different product categories.
Creates an Uninterrupted, Stable Production Flow
Eliminates issues such as cylinder changeovers, gas depletion, or pressure fluctuations. The packaging line runs on a constant gas supply, minimizing production downtime.
Eliminates Dependence on External Supply
Removes delays tied to cylinder and liquid nitrogen procurement, inventory planning burden, and price fluctuations. Gas is produced directly on-site.
Keeps Operational Costs Under Control
Reduces costs allocated to logistics, storage, and supply processes. The business can manage gas usage according to its own production schedule, making costs more predictable.

Frequently Asked Questions
+Why is nitrogen used in MAP systems?
Being inert, nitrogen lowers the oxygen level inside the package. This slows oxidation, delays product spoilage, and extends shelf life.
+How is a nitrogen generator integrated into a MAP system?
PSA nitrogen generators connect directly to the packaging line, continuously supplying the required gas during filling. They can be easily integrated into existing systems.
+Which food products commonly use MAP with nitrogen?
It's widely used for oxidation-sensitive products such as meat and meat products, dairy products, ready meals, snacks, coffee, and nuts.
