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

Cashew
Cashew nuts are a globally traded, high-value commodity that demands careful preservation. Long transport routes and variable climates expose cashews to moisture, insects and oxidation, putting quality, safety and value at risk.
Cashews are typically dried and stored under strict environmental conditions, with recommended relative humidity and temperature ranges to prevent deterioration. In reality, cashews travel thousands of kilometers from origin to processing and consumption markets, encountering fluctuating climates along the way. Traditional jute or polypropylene bags offer little protection against these changes, increasing the risk of moisture uptake, infestation and odor absorption. Although cashews contain healthier fats and natural antioxidants, their oil content still makes them vulnerable to rancidity. For producers, processors and retailers, maintaining stable quality without constant environmental monitoring is a major challenge.
Challenges in cashew preservation
Long-distance stress
Cashew preservation is highly sensitive to external conditions. Moisture fluctuations can quickly lead to quality loss, while insect infestations remain one of the most common threats during storage and transport. Oxygen exposure accelerates oxidation and rancidity, reducing shelf life and sensory quality. In addition, cashews readily absorb surrounding odors, which can damage product integrity during mixed cargo storage.
These risks are amplified by the long supply chains typical in the cashew industry. Cashews often pass through multiple climate zones, making consistent storage conditions difficult to maintain. Conventional packaging requires continuous monitoring and corrective actions, increasing operational complexity and cost. A solution that isolates the product from its environment is essential.

The VacQPack solution for cashews
Stable atmosphere
VacQPack creates a controlled inner environment around cashews using bulk-sized Modified Atmosphere Packaging (MAP). High-barrier liners restrict oxygen and water vapor transmission, protecting cashews from oxidation, condensation and external odors. Combined with low pressure and a controlled gas atmosphere, the VacQPack system effectively eliminates insect activity and stabilizes quality regardless of external climate conditions. Fully organic and residue-free, VacQPack enables long-distance storage and transport without continuous environmental monitoring, extending shelf life and helping cashew producers and traders reduce losses while delivering consistent quality.
- 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.
