vQm Modified Atmosphere Packaging (MAP) helps protect the origin quality and extend the shelf life of peanuts during storage and transport. Oxygen is extracted from the packaging and replaced with carbon dioxide (CO₂) or nitrogen (N₂), creating a stable and protective atmosphere around the product.
Peanuts have a high oil content and high proportion of unsaturated fats, making them particularly sensitive to oxidative quality deterioration during prolonged storage and transport. Exposure to oxygen can lead to rancid or stale flavours and reduce the natural aroma, colour, ultimately lowering the commercial quality of the peanuts.
Correct drying, moisture control and product inspection remain essential, as MAP cannot restore peanuts that are already too moist, oxidised, mould-affected or otherwise damaged.
Applying Modified Atmosphere Packaging to semi-bulk peanuts can help growers, processors, exporters and ingredient suppliers preserve product quality and extend shelf life during storage and international transport.
By reducing oxygen exposure and limiting external oxygen ingress, vQm MAP helps slow lipid oxidation and the development of stale or rancid flavours. This supports the preservation of the natural flavour, aroma and colour of peanuts throughout storage and transport.
High-barrier liners limit moisture exchange with the external atmosphere. This helps peanuts maintain their required moisture level and natural texture while reducing the risk of rehydration, condensation-related damage and mould development.
Modified Atmosphere Packaging can be used to treat insects across all life stages in, using low-oxygen, CO₂-rich or N₂-rich atmospheres without conventional toxic fumigants. For applications specifically focused on insect treatment, please read our Non-chemical Insect Treatment page for requirements and further guidance.
By helping peanuts maintain their quality for longer, MAP provides greater flexibility in deciding when products are stored, shipped, processed or sold based on demand, logistics and market conditions.
Designed for efficient vacuum and gas flushing of full big bags and wrapped pallets.
A reliable seal is essential for maintaining the modified atmosphere inside the packaging. The recommended sealer depends on the selected packaging option.
Designed to measure and verify MAP conditions. Measuring the and CO₂ concentrations supports quality assurance and confirms that the required MAP conditions have been achieved.
To transport semi-bulk peanuts we recommend the following packaging:
All packaging is designed with the vQm valve sealed inside (that enables efficient gas flushing through one secure connection point at amazing speed) Explore the vQm Two-Way Valve →
Its form-stable square design reduces bulging and helps maximise the use of available storage and container space.
If you prefer using palletised sacks, boxes or other existing cacao packaging, you can stack them on pallets and enclose the entire unit in a vQm Wrapping Liner or a Hood liner in case an automated palletizer is used. This protects whole shipments at once without altering your existing bagging process.
Protect dried fruit against oxidation, moisture fluctuations and insects while preserving its flavour, appearance and commercial value from origin to destination.
