Modified Atmosphere Packaging for semi-bulk macadamias

How Modified Atmosphere Packaging preserves macadamia quality

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

Because macadamias 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 delicate taste, aroma and commercial value.

Correct drying, moisture control and product inspection remain essential. MAP cannot restore macadamias that are already too moist, oxidised or damaged.

Benefits for macadamia and your business

Applying MAP to semi-bulk macadamias can help growers, processors, exporters and ingredient suppliers extend shelf life and preserve product quality throughout 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 taste, aroma and colour of macadamias.

Stabilised moisture content

High-barrier liners limit moisture exchange with the external atmosphere, helping macadamias retain their texture and reduces the risk of softening, excessive drying, condensation or mould growth.

Non-chemical insect treatment

Flushing bags with   or   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 macadamias preserve their quality for longer, MAP provides more flexibility in deciding when they are stored, shipped, processed 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 macadamias 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 →

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.
