Food Grade Gases
Afrox Freshline nitrogen and CO₂ for MAP packaging, flash freezing, carbonation, and controlled-atmosphere storage.
FOOD GRADE GASES
Afrox Freshline certified food-grade gases for packaging, freezing, carbonation, and dispensing.
Stargas delivers Afrox Freshline food-grade nitrogen and CO₂ for food and beverage processing, packaging, and dispensing applications. Our products meet all relevant safety, quality, hygiene, and compliance legislation.
Food-grade nitrogen is odourless, colourless, and tasteless. It does not affect food quality, is non-flammable, and does not support combustion. With a purity of 99.995%, it's the industry standard for MAP packaging and controlled atmospheres.
From flash freezing and modified atmosphere packaging to carbonation and draught beer dispensing, we supply the right gas, in the right format, with full traceability and documentation.
Afrox Freshline gases are certified food-safe and fully traceable — giving you compliance, quality, and peace of mind for every product line.

NITROGEN VS CARBON DIOXIDE
Both play critical roles in food and beverage applications, but they serve very different purposes.
| Application | Nitrogen (N₂) | Carbon Dioxide (CO₂) |
|---|---|---|
| Carbonation | Does not carbonate | Carbonates beverages |
| Taste Impact | Neutral, smooth | Sharp, acidic bite |
| Draught Beer | Stouts & nitro beers | Lagers, ales & ciders |
| Packaging | Displaces oxygen | Preserves carbonation |
| Shelf Life | Extends freshness | Maintains sparkle |
| Solubility | Low solubility | Highly soluble in liquid |
When to Use Nitrogen (N₂)
- Dispensing stouts and nitrogenated beers
- Modified atmosphere packaging (MAP) for fresh produce
- Purging oxygen from food containers and tanks
- Cryogenic freezing and flash chilling
When to Use Carbon Dioxide (CO₂)
- Carbonating soft drinks, sparkling water, and beer
- Dispensing lagers, ales, and ciders on draught
- Preserving carbonation in packaged beverages
