Preserving Peanut Quality Under Hermetic Storage
Peanuts travel long distances and often remain in storage for extended periods. During that time, quality loss is a persistent concern. Rising free fatty acids, flavour deterioration and mould risks

Soybean seeds
Soybean seeds are a high-value agricultural input where storage quality directly affects germination, vigour and yield potential. Preserving seed integrity over time requires precise control of moisture, temperature and biological activity.
Soybean seeds are particularly sensitive during storage due to their high oil content and hygroscopic nature. Moisture fluctuations accelerate lipid peroxidation, leading to rapid loss of viability and seed quality. Elevated temperatures and long storage durations further intensify deterioration, while mechanical damage during post-harvest handling weakens seed structure and germination performance. Conventional preservation often relies on refrigerated storage, which is costly and energy-intensive. In large-scale seed production regions, especially warm climates, a reliable solution is needed that stabilizes internal conditions without compromising seed vitality or increasing operational complexity.
Challenges in soybean seed preservation
Viability at risk
Soybean seed preservation is challenged by the interaction of moisture, temperature and time. Excess humidity promotes mycoflora development, accelerating deterioration and reducing germination capacity. At the same time, soybean seeds readily absorb or release moisture from their surroundings, making them highly sensitive to ambient conditions.
Mechanical stress during handling causes micro-damage that may not be visible but significantly reduces storage performance. Lipid peroxidation further degrades seed quality, especially under oxygen-rich conditions. Insect presence compounds these risks, as eggs may survive initial cleaning and hatch during storage. Maintaining stable, low-oxygen conditions is essential to protect soybean seed viability over extended periods.\

The VacQPack solution for soybean seeds
Controlled viability
VacQPack preserves soybean seeds using bulk-sized Modified Atmosphere Packaging (MAP) combined with vacuum and controlled storage temperature. High-barrier EVOH liners maintain a stable internal atmosphere with very low oxygen and water vapor transmission, protecting seeds from external humidity and temperature fluctuations. The low-oxygen environment slows lipid peroxidation, inhibits fungal growth and eradicates insects organically, including eggs. Unlike cold chambers, VacQPack uses ambient temperature as an active tool, reducing energy costs while preserving germination potential, vigour and long-term seed quality—even in hot, remote production regions.
- 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.
