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

Oats
Oats are a nutritious grain where storage quality directly affects food safety and functional performance. Moisture, insects and condensation are constant threats, especially in organic oat supply chains where chemical treatments are not an option.
Oats are typically harvested at low moisture levels to avoid shattering, yet even small deviations during storage can cause rapid quality loss. Moisture levels above safe thresholds encourage fungal growth, while condensation during storage or transport can quickly compromise bulk volumes. In conventional infrastructure, insect infestations may occur within a few months, even under good handling practices. As oats are rich in fats and proteins compared to other grains, maintaining stable conditions is critical to preserve shelf life, nutritional value and processing suitability. Long-term storage therefore requires precise atmospheric and moisture control rather than reactive intervention.
Challenges in oat preservation
Moisture sensitive
Oat preservation is primarily challenged by moisture dynamics. Condensation and evaporation during storage or transport can rapidly raise moisture content, increasing the risk of fungal growth and spoilage. Once moisture exceeds safe limits, quality degradation accelerates and food safety is compromised.
Insect infestation is another major risk, particularly in bulk storage where oxygen remains available. Traditional chemical fumigation, such as phosphine, is increasingly restricted or undesirable for organic oats. Temperature fluctuations further complicate storage stability, while inconsistent packaging methods can lead to uneven preservation across volumes. Effective oat storage requires a system that keeps moisture stable, oxygen low and conditions consistent, regardless of packaging size or external environment.

The VacQPack solution for oats
Consistent control
VacQPack preserves oats using bulk-sized Modified Atmosphere Packaging (MAP) that actively controls oxygen, moisture and condensation. High-barrier liners combined with vacuum and inert gas flushing using COâ‚‚ or nitrogen create a low-oxygen environment that inhibits insects and slows biological activity. The VacQPack Cleanpack Combi applies identical preservation parameters across both bulk and smaller packaging formats, ensuring consistent quality throughout the supply chain. Fully organic and residue-free, VacQPack extends oat shelf life while maintaining safety, nutritional integrity and operational flexibility.
- 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.
