Preserving Rice Quality with Nitrogen Storage
Rice is often regarded as a stable commodity. Once dried to a safe moisture level, it is assumed to store well and travel across continents without significant risk. In practice,

Rice is a staple food and a globally traded commodity where preservation quality directly impacts food safety, value and logistics. Moisture, insects and poor storage conditions remain the primary threats throughout post-harvest handling and transport.
After harvest, rice must be carefully dried and stored to maintain its physical and chemical stability. Storage practices vary widely across regions, influenced by climate, infrastructure and grain type. Traditional open storage systems expose rice to humidity, pests and environmental contamination, increasing the risk of spoilage and loss. Scientific consensus recognizes Modified Atmosphere Packaging as an effective alternative to reduce deterioration and protect quality. For organic rice in particular, the need for a residue-free, reliable preservation method is critical, as poor storage conditions quickly translate into higher costs and rejected cargo.
Challenges in rice preservation
Climate exposed
Rice preservation is strongly influenced by moisture control. If rice is stored above safe humidity levels, microbial growth and spoilage accelerate rapidly. In warm and humid climates, insect infestation becomes a persistent problem, while oxidation and enzymatic activity degrade quality over time.
Traditional storage systems often leave rice exposed to rain, rodents and birds, increasing contamination risks. Chemical fumigation is still commonly used, but raises regulatory, residue and acceptance issues, especially for organic rice. Long storage periods and transoceanic transport further complicate preservation, as fluctuating conditions are difficult to manage consistently. Effective rice storage requires isolation from the external environment and stable internal conditions.

The VacQPack solution for rice
Stable environment
VacQPack preserves rice using bulk-sized Modified Atmosphere Packaging (MAP) that creates a stable, homeostatic inner environment independent of external conditions. High-barrier liners, used as inside or outside liners, control oxygen and moisture levels following proper post-harvest drying. By applying vacuum and inert gases, VacQPack delivers a fully organic bio fumigation that suppresses insects and slows spoilage without chemicals. Proven in international case studies, including transoceanic logistics, VacQPack improves storage safety, preserves rice quality and optimizes global rice supply chains.
- Consistent product quality and taste
- Reduced food loss and waste
- Full control over product safety
- Optimized total cost of ownership (TCO)
- Non-chemical, organic treatment

Best practice
Learn how customers across different commodities use VacQPack as a best practice for quality protection. By applying natural MAP, they prevent insects, control moisture, and safeguard product value throughout storage and transport.
Particularly on humid and hot areas, problems like condensation, variation of moisture content, oxidation and in some cases insect infestation, are common on the difficult task of keeping the quality of soybean seeds during storage.
The refrigeration is the conventional technique for preservation, but it requires a great deal of investment on infrastructures and implies significant expenditures on energy. Besides, once the seed leaves the refrigeration mode, gets again vulnerable and enters in a rapid degradation process.
