“Food grade gases” are as gases conforming to “food grade” regulations, that are used as a processing aid and/or additive in food and beverage processing.
Food grade gases (food grade nitrogen N2, food grade oxygen O2, food grade carbon dioxide CO2) have different applications in food and beverage industry:
- Food-grade gases for Modified Atmosphere Packaging (MAP), a technology to extend the shelf life of food without altering the physical or chemical properties. For example, the food-grade oxygen in red meat packaging helps retaining the high level of oxygen concentration that prevent colour changing caused by the oxidation of the red pigment.
- In food freezing, food-grade nitrogen is used in cryogenic freezing system, a technology that quickly lowers the temperature of food products, either to improve productivity for downstream processes or as a means of natural preservation by refrigerated temperatures.

- Food-grade nitrogen used in bottom-injection chilling. This cryogenic chilling technology added to the current customer’s blender, mixer, cooking kettle, or holding vessel that quickly reduces food product’s temperature and maintains temperature consistency.
- Food-grade nitrogen for the LIN (liquid-nitrogen) dosing systems commonly used in bottling processes for non-carbonated beverages (water, juices, teas, etc.). The dosing systems add a droplet of liquid nitrogen and trap it by immediately capping the bottle. The trapped droplet expands as it vaporizes and increases the internal pressure. The pressure increase ‘rigidifies’ the bottle, making it robust enough to stack.
Operating our own Air Separation Plant and supplying directly to customers by delivery tankers, Linde Vietnam brings to customers food-grade gases at high-purity, consistently high quality and competitive price.
The food-grade nitrogen and food-grade oxygen are supplied in different modes in relevant to customer’s demand volume from 10 Nm3/hr to more than 1,000 Nm3/hr. We also provide On-site plant solutions for customer with high demand of Nitrogen.
