Modified Atmosphere Packaging for semi-bulk pecans

How Modified Atmosphere Packaging preserves pecan nuts quality

vQm Modified Atmosphere Packaging (MAP) protects the origin quality and extends shelf life by creating a stable, protective environment around the pecans during storage and transport by extracting oxygen and replacing it with CO2 or N2.

Correct drying and product inspection remain essential, as MAP cannot correct pecans that are already too moist or damaged.

Benefits for pecan nuts and your business

Applying modified atmosphere in semi-bulk size packaging can help pecan growers, processors, exporters and ingredient suppliers extend shelf life and preserve product quality during storage and transport.

Protection against oxidation

By reducing oxygen exposure and limiting external oxygen ingress, vQm MAP helps slow lipid oxidation and the development of rancid flavours — preserving the natural flavour and colour of pecans during storage and transport.

Stabilised moisture content

High-barrier liners limit moisture exchange with the external atmosphere, helping pecans retain their natural texture and reducing the risk of softening, drying out or mould growth.

Non-chemical insect treatment

Flushing bags with CO2 or N2 naturally eliminates all insects across all life stages (eggs, larvae, pupae, and adults), removing the need for harmful pesticides like phosphine.

Greater commercial flexibility

By helping to preserve quality for longer, MAP provides more flexibility in deciding when pecans are stored, shipped or sold, based on demand, logistics and market conditions.

Recommended equipment

High-Speed Conditioning Unit

Designed for efficient vacuum and gas flushing of full big bags and wrapped pallets.

Sealer

A reliable seal is essential for maintaining the modified atmosphere inside the packaging. The recommended sealer depends on the selected packaging option.

Handheld CO2/O2 sensor

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.

Recommended packaging

To transport semi-bulk pecans we recommend the following packaging:

All packaging is designed with the vQm valve sealed inside — enabling efficient gas flushing through one secure connection point at amazing speed. Explore the vQm Two-Way Valve →

Quadro Big Bag

Its form-stable square design reduces bulging and helps maximise the use of available storage and container space.

Wrapping and Hood Liners


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.
