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
Chenopodium quinoa
Quinoa
Quinoa is a high-value Andean grain prized for its nutritional profile and functional properties. Preserving its sensory quality, safety and market value during storage and transport requires precise control of oxygen, moisture and biological activity.
Compared to common cereals, quinoa contains higher fat levels and is more sensitive to environmental conditions. Air humidity directly influences seed moisture, and when combined with elevated temperatures, respiration intensifies. This can lead to self-heating, moisture buildup and quality degradation. Conventional small-bag packaging offers limited protection and increases handling costs. As global trade in organic quinoa expands, producers and traders increasingly need bulk solutions that protect organoleptic quality, enable efficient logistics and allow safe treatment of infested lots without chemical intervention.
Challenges in quinoa preservation
Sensitive grain
Quinoa preservation is challenged by a combination of physical, biological and safety risks. Elevated moisture and temperature increase respiration, causing self-heating and potential hot spots within bulk storage. This environment promotes insect development and microbial growth, leading to quality loss and contamination.
High fat content accelerates deterioration when oxygen is present, while insects and cross-contamination further reduce marketability. In severe cases, internal heating may create safety hazards. In addition, infested organic quinoa often loses commercial value, despite still being recoverable. Effective preservation requires airtight packaging, controlled atmosphere and the ability to treat and restore compromised lots without residues.
- Moisture instability
- Insect infestation
- Self-heating risk

The VacQPack solution for quinoa
Restored value
VacQPack preserves quinoa using bulk-sized Modified Atmosphere Packaging (MAP) with high-barrier liners that restrict oxygen transmission and stabilize moisture. Vacuum and controlled gas flushing reduce respiration and inhibit insects organically, while supporting efficient handling and logistics in 1–2 ton bulk units. Outside liners can also be applied to palletized bags when smaller packaging is required. VacQPack liners are resealable, allowing repeated sampling or partial unloading without losing protection. Even infested organic quinoa can be treated using CO₂, pressure and temperature, restoring quality and returning the product to the market safely and residue-free
- 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.
