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
Zea mays
Corn / Maize
Corn is a globally important grain where storage quality directly affects safety, nutritional value and downstream use. Moisture, oxygen and biological activity must be carefully controlled to prevent spoilage during storage and transport.
After harvest, corn kernels remain biologically active. Respiration continues during storage, generating heat and moisture that can quickly destabilize bulk volumes. High moisture levels and warm temperatures stimulate fungal growth, fermentation and insect activity, leading to quality loss and safety risks. Conventional storage systems often struggle to control these processes consistently, especially for organic corn where chemical fumigation is not desired. Maintaining low oxygen levels and stable internal conditions is essential to preserve corn quality, prevent spoilage and support long-term storage across different climates and infrastructures.
Challenges in corn preservation
Active grain
Corn preservation is challenged by its high biological activity. Residual respiration increases internal temperature and moisture, creating ideal conditions for fungi and spoilage organisms. Elevated moisture levels accelerate fermentation, yeast development and fatty acid degradation, especially in warm environments.
Insects further complicate storage, while uncontrolled oxygen availability sustains both pests and microbial growth. In bulk storage, moisture and heat can spread rapidly through the grain mass, amplifying damage. Traditional storage systems rely heavily on environmental control, which is difficult to maintain consistently. Effective preservation requires actively limiting oxygen to slow respiration and stabilize the grain.

The VacQPack solution for corn
Respiration control
VacQPack preserves corn using bulk-sized Modified Atmosphere Packaging (MAP) that actively reduces oxygen levels to control seed respiration and biological activity. Vacuum combined with nitrogen flushing lowers oxygen to around 4% or less, further reduced by natural seed respiration. High-barrier liners prevent oxygen and moisture ingress, inhibiting fungi and insects organically. By stabilizing internal temperature and moisture, VacQPack prevents fermentation and spoilage, enabling safer long-term storage of organic corn without chemical fumigation while preserving nutritional quality and operational efficiency.
- 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.
