Food-grade N₂ displaces oxygen in packaging to extend shelf life 2–5×. Chips, coffee, nuts, fresh produce, baked goods, dairy, and prepared meals.
N₂ flushing reduces residual O₂ to <0.5%, slowing oxidation and microbial growth. Shelf life increases 2–5× vs. air packaging — less waste, longer distribution reach.
Replace artificial preservatives with natural oxygen displacement. No chemical additives needed. Clean label appeal for health-conscious consumers and retailers.
On-site N₂ generation costs pennies per cubic meter. No liquid N₂ delivery charges, cylinder deposits, or scheduled refills. Payback typically 6–10 months.
304/316L stainless steel construction. Food-grade filtration with 0.01 micron. Compliance documentation for FDA and EU food contact regulations.
