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

Nuts
Nuts are high-value, nutrient-rich commodities where freshness, taste and shelf life directly determine market value. From origin to destination, protecting nuts against oxidation, moisture and infestation is essential for quality preservation.
Tree nuts such as cashew, almond, hazelnut, pistachio, walnut, macadamia and pecan, as well as groundnuts produced at scale, are especially sensitive due to their fat content. Exposure to oxygen, humidity and mold can quickly lead to rancidity and quality loss. In recent years, the nut industry has shifted from traditional small-bag handling to bulk packaging, improving efficiency and control. This transition requires packaging that not only protects quality, but also supports mechanized handling, optimized logistics and residue-free preservation. VacQPack enables this shift by safeguarding nuts throughout storage and transport, while maintaining the sensory qualities buyers and consumers expect.

The VacQPack solution for nuts
Bulk protection
VacQPack applies bulk-sized Modified Atmosphere Packaging (MAP) to protect nuts under stable, low-oxygen conditions throughout storage and transport. High-barrier liners prevent oxygen ingress and moisture migration, slowing oxidation and reducing the risk of rancidity, mold and insect infestation. The system supports large-volume big bags, enabling efficient palletized handling and optimized container loading without additional desiccants or secondary packaging. Fully organic and residue-free, VacQPack helps nut producers, processors and traders reduce losses, extend shelf life and preserve taste, texture and freshness across the entire supply chain.
- 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.
