vQm Modified Atmosphere Packaging (MAP) helps protect the origin quality and extend the shelf life of hazelnuts by creating a stable, protective environment during storage and transport. Oxygen is extracted from the packaging and replaced with carbon dioxide (CO₂) or nitrogen (N₂).
Because hazelnuts have a high natural oil content, they are particularly sensitive to oxidation. Reducing oxygen exposure helps slow the development of rancid flavours and protects their natural taste, aroma and colour.
Correct drying, moisture control and product inspection remain essential, as MAP cannot restore hazelnuts that are already too moist, oxidised or damaged.
Applying Modified Atmosphere Packaging to semi-bulk hazelnuts can help growers, processors, exporters and ingredient suppliers extend shelf life and preserve product quality during storage and transport.
By reducing oxygen exposure and limiting external oxygen ingress, vQm MAP helps slow lipid oxidation and the development of rancid flavours. This supports the preservation of the natural flavour, aroma and colour of hazelnuts during storage and transport.
High-barrier liners limit moisture exchange with the external atmosphere, helping hazelnuts retain their natural texture and reducing the risk of softening, excessive drying, condensation-related damage or mould growth.
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 hazelnuts 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 hazelnuts 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 hazelnuts against oxidation, moisture fluctuations and insects while preserving its flavour, appearance and commercial value from origin to destination.
