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
Prunus dulcis
Almonds
Almonds are a premium nut valued for taste, nutrition and versatility. Their high oil content makes them especially sensitive during storage and transport, where small deviations in conditions can quickly impact quality and market value.
Despite their natural antioxidants, almonds remain vulnerable to moisture, oxygen and environmental exposure. Their oil-rich composition accelerates rancidity when exposed to air, while hygroscopic behavior makes them prone to chemical and physical changes. Insects, pests and direct sunlight further threaten quality, and almonds easily absorb surrounding odors during storage. For organic almonds, preservation becomes even more complex, as chemical fumigation, irradiation or pasteurization are not acceptable options. Roasted almonds add another layer of risk, as oxidation can trigger mold growth and mycotoxin formation. Protecting almonds long-term requires precise control without compromising flavor, safety or organic integrity.
Challenges in almond preservation
Delicate balance
Almond preservation demands careful management of multiple interacting risks. Moisture migration encourages mold development, while oxygen exposure accelerates rancidity and flavor loss. The pointed shape of almonds adds a physical challenge, as inadequate packaging may perforate liners over time. Insects and pests can infest stored almonds, especially in warm climates or during long transoceanic transport.
For organic almonds, the challenge intensifies. Chemical treatments are not permitted, yet long-term storage and overseas logistics remain unavoidable. Roasted almonds are even more sensitive, as heat treatment increases susceptibility to oxidation and mycotoxin risks. In all cases, maintaining stable conditions without introducing residues or altering natural characteristics is critical to protect quality, compliance and commercial value.

The VacQPack solution for almonds
Organic control
VacQPack protects almonds using bulk-sized Modified Atmosphere Packaging (MAP) combined with high-barrier, puncture-resistant liners. By removing oxygen and creating a controlled atmosphere under low pressure, VacQPack slows oxidation, prevents insect activity and stabilizes moisture levels. The multi-layer EVOH-based liner resists perforation from almond edges while maintaining excellent gas and vapor barriers. Fully organic and residue-free, the VacQPack solution extends shelf life for raw and roasted almonds alike, preserving flavor, texture and nutritional value throughout long storage and global transport.
- 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.
