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
Triticum spelta
Spelt
Spelt is a premium ancient grain valued for its nutritional profile and traditional character. As demand grows, preserving its sensory qualities and organic integrity during storage has become essential for protecting value and market trust.
Spelt has re-emerged as a high-value grain, often stored for extended periods to meet specialty and organic market demand. While its thick husk offers some natural protection, spelt remains vulnerable to moisture imbalance and insect infestation during storage. In recent years, increasing pest pressure across Europe has intensified preservation challenges. Conventional solutions such as chemical fumigation or cold storage are either undesirable for organic products or costly and slow. Maintaining spelt’s original taste, structure and quality requires a controlled, residue-free approach that stabilizes conditions throughout storage and transport.
Challenges in spelt preservation
Ancient grain risks
Spelt preservation is primarily challenged by pest control and moisture dynamics. Weevils and moths increasingly attack stored spelt, particularly during long storage periods. While the husk provides partial protection, infestations can still develop and spread through cross-contamination.
Moisture fluctuations lead to condensation and evaporation, which can compromise grain quality and encourage biological activity. Traditional solutions such as silo bags, container liners or refrigeration offer limited control, require intensive handling or incur high energy costs. Chemical fumigation is incompatible with organic standards. The challenge lies in controlling insects, moisture and atmosphere precisely, while preserving spelt’s natural characteristics and keeping operations efficient.

- Moisture imbalance
- Cross contamination
- Organic compliance

The VacQPack solution for spelt
Natural control
VacQPack preserves spelt using bulk-sized Modified Atmosphere Packaging (MAP) that creates a stable, low-oxygen environment inside high-barrier liners. By combining vacuum, controlled gases and temperature as an active parameter, VacQPack eliminates insects organically, including eggs, without chemicals. COâ‚‚ is applied for rapid bio fumigation when infestations are identified, while nitrogen offers a cost-effective solution to control moisture and prevent condensation. The result is a flexible, energy-efficient alternative to fumigation, cold storage and silo systems, preserving spelt quality, safety and organic integrity over the long term.
- 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.
