1. Oxygen Scavenging and Lipid Protection
While makhana is extremely low in fat (under 0.5%), residual unsaturated fatty acids can undergo oxidation if exposed to atmospheric oxygen and heat over prolonged periods. Nitrogen purging (99.5% N2 purity) replaces headspace oxygen, preventing off-flavors and rancidity.
2. Structural Protection Against Transit Breakage
Puffed lotus seeds are fragile. Nitrogen pillow-packs create an internal cushion that protects popped lava from crushing during palletization, container handling, and rough freight journeys.
3. Shelf-Life Extended Beyond 12 Months
Hermetic barrier foil packaging paired with nitrogen flushing ensures that export consignments arriving in North America or Europe retain identical oven-fresh crispness as the day they were processed in Bihar.
